Writing 101 Day Three

Practice makes perfect.

Again, here is the WordPress theme for the day:

Day Three: Commit to a Writing Practice

Today’s Prompt: Write about the three most important songs in your life — what do they mean to you?

Nailing Brahms’ Hungarian Dance Number 5 on your alto sax. Making perfect pulled pork tacos. Drawing what you see. Or, writing a novel. Each requires that you make practice a habit.

Today, try free writing. To begin, empty your mind onto the page. Don’t censor yourself; don’t think. Just let go. Let the emotions or memories connected to your three songs carry you.

Today’s twist: You’ll commit to a writing practice. The frequency and the amount of time you choose to spend today — and moving forward — are up to you, but we recommend a minimum of fifteen uninterrupted minutes per day.

The basic unit of writing practice is the timed exercise. – Natalie Goldberg

Author Natalie Goldberg says to “burn through to first thoughts, to that place where energy is unobstructed by social politeness or the internal censor.” Here are some of her rules of free writing practice from Writing Down the Bones, which we recommend you keep in mind:

Keep your hand moving. (Don’t pause to reread the line you’ve just written. That’s stalling and trying to get control of what you’re saying.)

Don’t cross out. (That is editing as you write. Even if you write something you didn’t mean to write, leave it.)

Don’t worry about spelling, punctuation, grammar. (Don’t even care about staying within the margins and lines on the page.)

Lose control.

Don’t think. Don’t get logical.

Go for the jugular. (If something comes up in your writing that is scary or naked, dive right into it. It probably has lots of energy.)

Jorge Luis Borges said: “Writing is nothing more than a guided dream.” So, what are you waiting for? Get writing. Fifteen minutes. Go. And then, do it again tomorrow, and the day after, and the day after.

Now having written a daily post for well over five years, I’m comfortable with the concept of committing to a writing practice.

Thus I’m going to republish something that gets to the heart of more worldly matters – keeping a smile on your face in these ‘interesting’ times. It comes from a blog that I recently started following: One Regular Guy Writing about Food, Exercise and Living Longer.

How You Can Benefit from a Positive View on Your Life – WSJ

Regular readers know that I have embraced the theory of positive psychology. I have written a number of posts on the benefits of a positive point of view. You can find an index of them at the end of this post.

Meanwhile, I was thrilled to see Elizabeth Bernstein’s piece in the Personal Journal of Tuesday’s Wall Street Journal entitled “It’s Healthy to Put a Good Spin on Your Life.“

In a study of a large number of adults in their mid to late 50’s researchers found that “when people displayed higher levels of agency, communion and redemption and lower levels of contamination, their mental health improved. They consider good mental health to be low levels of depression and high levels of life satisfaction and psychological and social well-being.”

They explained the four keys to good mental health as follows:

• Agency—Did the subjects feel able to influence and respond to events in life, or did they feel battered around by the whims of external forces?
• Communion—Are the people connected to others or disconnected?
• Redemption—Did the subjects take a negative experience and find some positive outcome?
• Contamination—Did they tell narratives of good things turning bad?

I would like to point you to a post I wrote in May of 2011 called Super Tools for Handling Stress.

In it I quoted Maggie Crowley, Psy.D., a Health Psychologist at the center for Integrative Medicine and Wellness at Northwestern Memorial Physicians Group.

Dr. Crowley listed the following as maladaptive coping strategies:

*Demand our circumstances be different
*Devalue ourselves and others
*Demean/blame ourselves and others
*When the above fail to work, do we choose another strategy?
*Or, do we double our ill-conceived efforts and feed our downward spiral.

She said that we needed something to shift our mental gears out of the stressful/fearful response that triggers that damaging cascade of negative emotion. She suggested the following activities that set off the parasympathetic approach:

*Practicing appreciation
*Making choices that are positive
*Using constructive language
*Employing our strengths and personal power.

I think that there is a great similarity between the four keys to good mental health mentioned in the Journal and the points made by Dr. Crowley in dealing with stressors.

Regarding positive psychology, I have found it answered a lot of questions for me. If you are interested you can explore it in the following posts:

This is such incredibly powerful and useful advice with lots of further reading to boot!

For we are bombarded with negative news from all quarters and having a healthy relationship with oneself and, thence, with the world around us is, in the end, what life is all about.

Seeing the bigger picture.

Look beyond appearance and prejudice.

I had in mind to republish a recent George Monbiot essay but then saw this post from Alex Jones’ blog The Liberated Way. It seemed a perfect follow-on to yesterday’s Picture parade ninety. It is republished with Alex’s kind permission.

Look beyond appearance and prejudice

Everything in nature is good says the philosopher Heraclitus. Humans love to divide everything into good and bad, thus missing the beauty of what nature offers in the blindness of their prejudices.

A few years ago, I intervened to save a baby crow from traffic and school children, taking it to a veterinarian surgery, who had the contacts of people who could look after it. The receptionist annoyed me on seeing the bird describing it as “evil.”

In fact, if people can look beyond the superstitious nonsense surrounding these black feathered birds, there is an intelligent empathy lurking inside these beautiful corvids. If humans, dolphins and octopuses are in the top division of “intelligent” animals, the corvids, including magpies, jackdaws, ravens, crows, choughs and rooks, are in the same division. The corvids use tools, play, can problem-solve, express empathy and have a rudimentary sense of self based on experiments showing they recognise themselves in a mirror. The BBC recently reported how a child had developed a close relationship with crows she was feeding in the garden, birds that were leaving her gifts. A flood of feedback by readers revealed that gift-giving by corvids to those showing kindness to them was common around the world.

The symbol of my town port is the raven. My business carries the logo of the raven, a symbol for me of its intelligence. The stories of various archetypes such as Apollo, the Celtic Mercury and Odin had ravens as their messenger birds, who symbolised memory, thought, wisdom, intelligence, and the gathering or delivery of knowledge.

The sad situation is that most people blind themselves to the beauty of a living thing like a crow or raven, based on appearance and prejudice, so that they will do it harm, even though it might manifest the very qualities of intelligence and empathy that humans admire but often appear to lack.

There was a recent TED Talk that fits very nicely with today’s theme. It’s just fifteen minutes long. Enjoy.

What do you call a veterinarian that can only take care of one species? A physician. In this short and fascinating talk, Barbara Natterson-Horowitz shares how a species-spanning approach to health can improve medical care of the human animal — particularly when it comes to mental health.

Protecting the brain.

The joys of growing ever more old!

Last Saturday, in a humorous post called Cognitive Ageing, I wrote:

Or put another way: I can remember everything except the things I forget.

Like many others of my age, the short-term memory is not as sharp as it used to be (not that I can remember when that was! 😉 )

Today’s post is to pass on a recommendation for a programme called Lumosity. It was recommended to me by my local doctor and I signed up in February of this year. Clearly, it is impossible to know, in a scientific way, how much good it has done me but instinctively I feel it has made a strong, positive difference. Let me quote from their website:

The Science Behind Lumosity

Neuroplasticity: how the brain is capable of change

Scientists have historically believed that once a person reaches adulthood, their cognitive abilities are immutable. But beginning in the early twentieth century, that theory has been contested by evidence suggesting that the brain’s abilities are in fact malleable and plastic. According to this principle of neuroplasticity, the brain is constantly changing in response to various experiences. New behaviors, new learnings, and even environmental changes or physical injuries may all stimulate the brain to create new neural pathways or reorganize existing ones, fundamentally altering how information is processed.

One of the most dramatic examples of neuroplasticity at work comes from a 2000 brain scan study on London taxi drivers (Maguire et al., 2000). In order to earn a license, London taxi drivers typically spend about two years learning to navigate the city’s serpentine streets. What mark, the study’s researchers wondered, did this long, rigorous period of training leave on taxi drivers’ brains? Under the scrutiny of fMRI scans, 16 male taxi drivers in this study were revealed to have larger hippocampuses than a control group of 50 healthy males of similar ages. And the longer the time spent as a taxi driver, the larger the hippocampus tended to be. As a brain area involved in memory and navigation, the hippocampus likely changed in response to the taxi drivers’ experiences.

Most instances of neuroplasticity-based changes in the brain are much more subtle. But in recent decades, it’s cases like that of the London taxi drivers that have inspired certain members of the scientific community to pursue the next logical step in research: rather than passively waiting to see how the brain might respond to circumstances, is it possible to direct that capacity for change, targeting improvements in specific key abilities?

The science of cognitive training seeks to answer this question. In 2013 alone, 30 cognitive training studies were registered on the government database ClinicalTrials.gov. Lumosity scientists, with the help of outside collaborators, contribute to this research effort: so far, 7 peer reviewed studies have been published using Lumosity as a cognitive training tool for diverse populations, including healthy adults, cancer survivors, elderly people, and children with a genetic disorder.

Maguire, E. A., Gadian, D. G., Johnsrude, I. S., Good, C. D., Ashburner, J., Frackowiak, R. S. J., & Frith, C. D. (2000). Navigation-related structural change in the hippocampi of taxi drivers. Proceedings of the National Academy of Sciences of the United States of America, 97(8), 4398-4403.

Clearly, without trying it out yourself, it’s difficult for me to convey the nature of the ‘games’ that are provided.

What I can do is to republish a review that appeared on the website MD-Health.

Does Lumosity Work?

Lumosity was designed by several leading neuroscientists, which adds an air of credibility to this popular site, and combines the perks of social networking with brain training technology that supposedly makes your brain function at a higher level. But do these brain training games really work? There is plenty of evidence to support and contract the claims made by this popular gaming website, so it is important to look at the facts before making this determination.

What is Lumosity?

Lumosity is a webpage that features several different brain training games. Players are encouraged to create a profile that allows them to track their progress and play certain games that target mental flexibility, memory, problem solving, speed and attention. The idea is that performing these tasks regularly will help “train” your brain to function more effectively.

How Does Lumosity Work?

The web page explains that Lumosity is based on neuroplasticity, which treats the brain like a muscle that needs to adapt when it is presented with new challenges. The idea here is that if you present your brain with harder challenges, the portion of your brain meant to help solve them will grow larger and more functional. Previously it was believed that neuroplasticity was only available in children with brains that were still developing, but recent science leads researchers to believe that this skill is also available for adults.

Lumosity depends on two basic elements when users create their training program. First, users need to use the program regularly. This is similar to creating a daily routine at your local gym to work and tone your muscles. Your routine will not be as effective if you do not stick with it. The second part of this training program depends on users using many different types of games. There are 35 different games available on Lumosity in addition to many different skill levels within these games. Players should use a variety of different games and increase the difficulty level over time to help ensure that they are continuing to challenge the mind. Creating your initial profile gives the player an opportunity to see what weaknesses they have so they can create a routine that is ideal for their situation.

Is Lumosity Effective?

There are several scientific studies that lead scientists to believe that the brain training activities at Lumosity do have an effect on the brain. A study at the University of Michigan found that adults that used brain training games for a regular amount of time saw an improvement in test scores for dual attention asks and memory games in multiple tests. A similar study at Brown University also saw adults exceeding expectations in brain performance after using brain training games to aid in their work. These programs were found to boost the working memory which helps users keep track of tasks they are currently performing.

The thing to remember when analyzing these results is that they came from laboratory conditions. These adults used Lumosity games for hours every day for several months. Users that do not work on a similar schedule will not see these types of results. There is a great deal of evidence that supports the idea that brain training games can help grow and develop the mind, but not necessarily any evidence that Lumosity and the brain training games available here are more effective than other training games that are on the market elsewhere. In general, keeping the mind active and challenging your mind to learn more advanced tasks and ways of thinking are healthy and can help you perform tasks more effectively, and if Lumosity helps you accomplish this, then it can be seen as a positive asset.

There was a review published in The Guardian newspaper back in April, 2013 from which this extract is offered:

According to the website for Lumosity, which devised these games and is one of the best-known internet providers of brain training, setting aside a few minutes each day to complete the above tasks can make you feel “smarter, sharper, and brighter”. By factoring in a mental workout in the same way that we might go to the gym to exercise, we get cleverer and our IQ rockets.

That, at least, is the idea. And there are lots of people who buy it. In recent years, brain training has become a multimillion-pound business with companies such as Jungle Memory, Nintendo and CogniFit developing a wide range of user-friendly neuroscientific puzzles for the average punter. Lumosity itself has grown by 150% year-on-year since its launch in 2005 and now reaches more than 35 million people worldwide. In January alone, the company’s mobile app was downloaded nearly 50,000 times a day and its revenue hit $24m (£16m).

Co-founded by Michael Scanlon after he abandoned his neuroscience PhD at Stanford University, California, the business also has an extensive research programme that studies the effects of computerised cognitive training as well as conducting experiments over the web.

I can also republish another article from the Lumosity website:

The Science Behind Lumosity

The scientific roots of the Lumosity program

Research has found that certain types of activities may impact the brain more than others (Mechelli et al., 2004; Gaser and Schlaug, 2003; Draganski et al., 2006). It’s believed that as an activity is repeated, the brain tends to fall back on the same set of existing neural pathways. To continue changing, the brain must be exposed to novel, adaptive experiences that challenge it to work in new ways.

Drawing on this idea, Lumosity is designed to give each person a set of exercises that challenge their cognitive abilities.

Lumosity “games” are based on a combination of common neuropsychological and cognitive tasks, many of which have been used in research for decades, and new tasks designed by an in-house science team. Working with experienced game designers, Lumosity neuroscientists have transformed these tasks into over 40 challenging, adaptive games.

Lumosity’s game-based training program is designed to expose your brain to gradually increasing levels of challenges, adapting game difficulty to your individual ability level. As your scores increase, you may encounter new or more difficult games. Modelled from the concept of a physical personal trainer, Lumosity pushes you to operate at the limits of your abilities and stay challenged.

Lumosity is not expensive and while it is impossible to be objective about the positive difference it is giving me I wouldn’t give up on it.

Now where did I leave my car keys???

The continuing story of dogs and humans.

Staying with the theme of the relationship with humanity’s oldest friend.

Yesterday, I offered the first of two articles forwarded to me by local friend Jim, a vet, about the domestication of the wolf.

Here is the second.

Study narrows origin of dogs

By Krishna Ramanujan/ January 16th, 2014

Genomic sequencing of genetically divergent dogs, such as this basenji from the Congo, together with wolves and other wild canids, provides rich information about the history of domestic dogs.

The paper did not include a picture of Basenji dogs but a web search found the one above. Source: https://www.basenji.org/BasenjiU/Owner/103History/103History.html

Dogs were domesticated between 9,000 and 34,000 years ago, suggesting the earliest dogs most likely arose when humans were still hunting and gathering – before the advent of agriculture around 10,000 years ago, according to an analysis of individual genomes of modern dogs and gray wolves.

An international team of researchers, who published their report in PLoS Genetics Jan. 16, studied genomes of three gray wolves, one each from China, Croatia and Israel – all areas thought to be possible geographic centers of dog domestication. They also studied dog genomes from an African basenji and an Australian dingo; both breeds come from places with no history of wolves, where recent mixing with wolves could not have occurred.

Their findings revealed the three wolves were more closely related to each other than to any of the dogs. Likewise, the two dog genomes and a third boxer genome resembled each other more closely than the wolves. This suggests that modern dogs and gray wolves represent sister branches on an evolutionary tree descending from an older, common ancestor. The results contrast with previous theories that speculated dogs evolved from one of the sampled populations of gray wolves.

“This is an incredibly rich new dataset, and it has allowed us to carry out the most detailed analysis yet of the genetic history of dogs and wolves,” said Adam Siepel, associate professor of biological statistics and computational biology at Cornell and a co-author of the paper. “There are still many open questions, but this study moves the ball forward,” Siepel added.

Computer methods for analyzing complete genome sequences developed by Ilan Gronau, the paper’s second author and a postdoctoral associate in Siepel’s lab, played a key role in the collaboration. Gronau’s computer program, called G-PhoCS (Generalized Phylogenetic Coalescent Sampler), was previously applied with success in a 2011 Nature Genetics study of early human history and demographics.

In this case, G-PhoCS provided a detailed picture of the demographic changes that occurred during the divergence of dogs from wolves. The analysis revealed there was a sizable pruning in population of early dogs and wolves around the time of domestication. Dogs suffered a sixteenfold cut in population size as they diverged from an early wolf ancestor. Gray wolves also experienced sharp drops in population, suggesting that the genetic diversity among both species’ common ancestors was larger than represented by dogs and modern wolves. In addition, there was considerable gene flow between dogs and wolves after domestication. Accounting for gene flow was a major challenge in the analysis, and Gronau’s research on this topic proved valuable in obtaining an accurate model of canid demography.

The picture emerging from this study will allow researchers to better interpret genetic differences observed between dogs and wolves and to identify differences driven by natural selection. “This paper sets the stage for the next step in the study of dog domestication that tries to determine the genetic changes that enabled this amazing transformation,” said Gronau.

The study’s senior authors included geneticists John Novembre at the University of Chicago and Robert Wayne at the University of California, Los Angeles (UCLA). Adam Freeman, a postdoctoral fellow at UCLA, was the paper’s first author. Adam Boyko, a Cornell assistant professor of biomedical sciences, also co-authored the paper.

The study was funded by various sources, including the National Science Foundation, National Institutes of Health and Life Technologies.

Staying with the theme of our early companions, back on the 28th February, 2015 there was an article in the UK’s Guardian newspaper about the way wolves helped early modern man. Now I don’t have permission to republish the full article but here’s a taste:

How hunting with wolves helped humans outsmart the Neanderthals

Forty thousand years ago in Europe our ancestors formed a crucial and lasting alliance that enabled us to finish off our evolutionary cousins, the Neanderthals.

Dogs are humanity’s oldest friends, renowned for their loyalty and abilities to guard, hunt and chase. But modern humans may owe even more to them than we previously realised. We may have to thank them for helping us eradicate our caveman rivals, the Neanderthals.

According to a leading US anthropologist, early dogs, bred from wolves, played a critical role in the modern human’s takeover of Europe 40,000 years ago when we vanquished the Neanderthal locals.

The Guardian article finishes, thus:

Thus we began to change the wolf’s appearance and over the millennia turned them into all the breeds of dog we have today, from corgis to great Danes. Intriguingly, they may have changed our appearances as well, says [Professor Pat] Shipman, whose book, The Invaders: How Humans and Their Dogs Drove Neanderthals to Extinction, will be published this month. Consider the whites of our eyes, she states. The wolf possesses white sclera as does Homo sapiens though, crucially, it is the only primate that has them.

“The main advantage of having white sclera is that it is very easy to work out what another person is gazing at,” added Shipman. “It provides a very useful form of non-verbal communication and would have been of immense help to early hunters. They would been able to communicate silently but very effectively.”

Thus the mutation conferring white sclera could have become increasingly common among modern humans 40,000 years ago and would have conferred an advantage on those who were hunting with dogs.

By contrast, there is no evidence of any kind that Neanderthals had any relationship with dogs and instead they appear to have continued to hunt mammoths and elks on their own, a punishing method for acquiring food. Already stressed by the arrival of modern humans in Europe, our alliance with wolves would have been the final straw for Neanderthals.

Nor does the story stop in Europe, added Shipman. “I would see this as the beginning of the humans’ long invasion of the world. We took dogs with us wherever we went after our alliance formed in the palaeolithic. We took them to America and to the Pacific Islands. They made hunting easy and helped guard our food. It has been a very powerful alliance.”

RISE AND FALL OF NEANDERTHALS

250,000 years ago The first Neanderthals appear in Europe.

200,000 years The first modern humans appear in Africa.

70,000 years The first modern humans leave Africa.

50-60,000 years Modern humans and Neanderthals share territory in Middle East.

45,000 years Modern humans enter Europe.

40,000 years Neanderthals disappear.

I don’t know about you but I find the history of our, as in man’s, relationship with wolves and thence with dogs to be not just romantic but spiritually significant. To know, as I hug one of our many huggable dogs here at home, that I am bonding my mind and emotions with an animal that has been my partner for tens of thousands of years is beautiful beyond words.

(I took a break of a couple of minutes at this point to grab my camera and take a photograph of Hazel sleeping next to my chair, as she so often does when I am writing. Then one of her when she looked up at me. Here they are:)

oooo

That second photograph reminds me that somewhere I read that dogs are the only animal that can look to where a human is directing a gaze or pointing a finger.

What an incredible relationship!

And human wisdom?

No other planet to move to!

The title of today’s post picks up the theme of yesterday’s post Dog Wisdom, that incorporated a wonderful essay from Mark Rostenko about the wisdom of dogs.

The words in the sub-heading came to me because, unlike wild dog packs, we do not have the luxury of our ‘alpha female’ deciding her pack’s territory is no longer viable and they needed to move on.

All of which serves as an introduction to a recent essay from Martin Lack over on the blog Lack of Environment. Martin is well qualified to write on such matters as climate as he has been a Fellow of the Geological Society (FGS) since 1992 and a Chartered Geologist (CGeol) since 1998. His essay was published on the 15th March and is called Merchants of Doubt need to do the math.

ooOOoo

A feature-length documentary, based on the content of the Merchants of Doubt book by Naomi Oreskes and Erik Conway, went on general release at movie theatres in the USA this weekend.

As Desmogbog.com points out, it has already attracted the attention of an odd mixture of ideologically-motivated deniers of the reality of anthropogenic climate disruption.

I say “odd” because, as per the above link, those who prefer to see climate science as a conspiracy to raise taxes (and install worldwide Communist government via the United Nations, etc.) include both longstanding disputers of inconvenient science like Fred Singer (who questions whether the movie is defamatory) and self-confessed non-experts like James Delingpole.

Both of the above would have done well to watch a recent BBC Four (television) programme – Climate Change by Numbers. In contrast to just about every other programme about climate change that you might have seen, this one is presented by three mathematicians. A 30-second trailer is inserted below but, if you have not seen the full 74-minute programme (opens in a new window), I really would recommend it.

http://www.youtube.com/watch?v=k2nyUAGezg4

The programme focuses on three numbers:
— 0.85 Celsius – the rise in average global surface temperatures since the 1880s.
— 95% – the certainty of the scientific community that this is primarily human-caused.
— 1 trillion tonnes – humanity’s carbon budget to avoid 0.85 increasing to 2 Celsius.

Along the way, the programme highlights the early work of Svante Arrhenius – who determined that a halving of atmospheric CO2 could cause a 4 Celsius drop in temperature (and therefore that a doubling of CO2 will cause a 4 Celsius rise).

With regard to the accuracy of computer models, the programme highlights the way in which this has been proven by their ability to predict the cooling effects of large volcanic eruptions.

With regard to our carbon budget, the programme highlights the fact that humanity has already burnt 0.5 trillion tonnes and, unless radical changes are made to global trends, will burn the remaining 0.5 trillion tonnes within 30 years. It also points out that, as ongoing events might well suggest, even 2 Celsius could have severe and pervasive impacts (as the IPCC described them last year).

All very inconvenient for libertarians everywhere, I guess.

Learning sleep from our dogs!

Lack of sleep can have a role in obesity and diabetes.

Hazel asleep on the living-room couch at 2pm yesterday.

The sub-heading is taken from an item on the BBC News website that I read yesterday morning. (I’m republishing it in full so that readers are fully informed.)

Lack of sleep can have role in obesity and diabetes, study says

By James Gallagher, Health editor, BBC News website, San Diego

If you need a lie-in at weekends to make up for lack of sleep in the week, you may be at risk of obesity and type 2 diabetes, a study suggests.

The sleeping habits of 522 people found those losing sleep on weekdays were more likely to develop the conditions.

The findings, shown at the Endocrine Society‘s annual meeting, suggested increasing sleep could help patients.

Experts said the findings were interesting and called for the idea to be tested in large trials.

Studies have already shown that shift work can rapidly put healthy people into a pre-diabetic state.

The action of throwing the body clock out of sync is thought to disrupt the natural rhythm of hormones in the body, leading to a host of health problems.

But the pressures of work and social lives mean many people cut their sleep during the week and catch up at the weekend. Researchers are investigating whether there is a health impact.

Widespread

The study, by a team at the University of Bristol in the UK and Weill Cornell Medical College in Qatar, assessed “sleep debt” – a measure of the difference in the nightly hours asleep on weekdays and at the weekend.

“We found that as little as 30 minutes a day sleep debt can have significant effects on obesity and insulin resistance,” said Prof Shahrad Taheri from Weill Cornell.

He added: “Sleep loss is widespread in modern society, but only in the last decade have we realised its metabolic consequences.

“Our findings suggest that avoiding sleep debt could have positive benefits for waistlines and metabolism and that incorporating sleep into lifestyle interventions for weight loss and diabetes might improve their success.”

The study was funded by the UK’s Department of Health, where 10% of healthcare budgets are already spent on treating diabetes.

The disease can lead to blindness, increase the risk of heart attacks and strokes, as well as damaging nerves and blood vessels – dramatically increasing the risk of a foot needing to be amputated.

What the researchers do not know is the impact of improving people’s sleep so they get more on a weeknight and do not need a weekend lie-in.

Dr Denise Robertson, a senior lecturer from the University of Surrey, commented: “This work is interesting and consistent with prospective data found in healthy individuals without type 2 diabetes.

“However, before this association between sleep length, obesity and metabolic status can be used in terms of public health we need the next tier of evidence.

“To date there have been no randomised controlled trials where sleep debt is addressed and a metabolic benefit is observed. However, the potential for such interventions to impact on health is great.”

So while it might be regarded as a little ‘tongue-in-cheek’ to say that we need to learn to sleep more effectively from dogs, the BBC item suggests that it’s not as silly as one might think.

Lilly, to the rear of Paloma, sleeping soundly yesterday afternoon.

In the photograph above of Lilly and Paloma, both Mexican feral dogs rescued by Jean many years ago, sleep and a gentle life have allowed Lilly to achieve the grand old age of 17! In human terms that would be the equivalent of 136-years-old!

1 minute for Irish Greyhounds

Featured by dogleadermysteries

Please help Irish Greyhounds by signing this Care2 petition

Save greyhound dogs’ lives in less than 1 minute

Bring Irish Greyhound Racing Regulations in line with the United Kingdom

I will not submit my readers to the horrors racing greyhounds endure or lose their lives from. I never thought any thing could be worse than dogs bred in puppy mills. After reading the Care2 petition’s explanation of the conditions and animal cruelty in Ireland’s dog racing world, now I feel sadder but an informed and wiser person.

My friend, Rosee Riggs, sent me this petition. The situation and welfare for dogs on Irish racetracks distresses all animal lovers everywhere. Without boring you with research and background, the essence of this petition effort targets raising Irish greyhound racing rules to match those in Great Britain.

4 great things about greyhound dogs

From Care2: legal changes needed to better protect Irish track greyhounds

Have a veterinarian present at all race meetings, trials and sales trials who must inspect every greyhound before it runs;
Provide the veterinarian with appropriate facilities;

Care2 Petition Bring Irish Greyhound Racing Regulations in line with the UK

Please sign and share

Thanks for reading, Deborah Taylor-French

ooOOoo

Delighted to say that at 15:30 PST yesterday, the Care2 Petition site read:

we’ve got 169,061 signatures, help us get to 170,000

and went on to explain the background to the petition:

There are major concerns about animal welfare issues relating to the racing greyhound industry in Ireland. Many puppies and older dogs which don’t perform to racing owner expectations are killed simply because they won’t make money for the owner. They are discovered in mass graves with their tattooed ears hacked off so they can’t be identified – so that their owners can’t be held accountable.

Dogs are generally kennelled, constantly muzzled, for 23-24 hours a day for their entire racing life. There are usually at least two dogs per small kennel, sharing one bed (with straw if they are lucky). The kennels are overcrowded, not properly maintained and badly cramped.

In the UK there are regulations which provide some protection for racing greyhounds. These regulations do not exist in Ireland where most racing greyhounds come from. Changes need to be made to bring the laws in Ireland in line with those in the UK. These rules aren’t perfect but they do offer a lot of improvements to the lives of these beautiful dogs.

Please sign the petition to show the Irish Greyhound Racing Board that the public cares about these dogs, to encourage them to support laws to protect these dogs.

At least 20 greyhounds a day, either puppies, which do not make the track because of lack of “prey drive”, or ‘retired’ dogs, aged between 18 months to 3-4 years, simply ‘disappear’ according to “records”. All dogs should be identifiable by the tattoos & registry records. When they are tattooed the dogs are roughly handled & dragged around by their ears with pincers.

There’s a bit of a smell!

The incredible power of the nose of a dog.

Young Oliver had an upset tummy during the night resulting in the bedroom carpet needing a little ‘sorting out’ after midnight. Thus I was very grateful that a human’s sense of smell is very much inferior to that of the dog!

Oliver sleeping in front of the wood-stove yesterday morning.

I couldn’t escape the irony that today’s post was inspired by an email from friend Dan Gomez. His email included the link to an article on the Brain Links website. It was called How a Dog Actually “Sees” the World Through Smell. Here’s how the article opened:

“The world of scents is at least as rich as the world of sight.”

Even though smell is the most direct of our senses and the 23,040 breaths we take daily drag in a universe of information — from the danger alert of a burning odor to the sweet nostalgia of an emotionally memorable scent — our olfactory powers are not even mediocre compared to a dog’s. The moist, spongy canine nose is merely the gateway into a remarkable master-machine which can detect smells in concentrations one hundred-millionth of what we humans require to smell something, and then transmute them into immensely dimensional and useful information about the world. So magnificent is the dog’s olfactory brawn — including the ability to sniff out skin, breast, bladder, and lung cancers with an astounding degree of accuracy and to literally smell fear — that to our primitive human perception it appears like nothing short of magic.

The article also included this short TED Talk but I have taken the liberty of including the paragraph that preceded the YouTube video.

How that neurobiological magic happens is what cognitive scientist Alexandra Horowitz — who heads the Dog Cognition Lab at Barnard College but has also produced a canon of invaluable insight on how we humans construct our impressions of reality — explains in this short animation from TED-Ed, based on her illuminating book Inside of a Dog: What Dogs See, Smell, and Know (public library):

Do go across and read the full article.

Mind you, referring back to our overnight doggy incident, I did find one paragraph slightly at odds with my personal views on the subject. It was this one:

We humans tend not to spend a lot of time thinking about smelling. Smells are minor blips in our sensory day compared to the reams of visual information that we take in and obsess over in every moment.

I’m here to tell you that at 1am yesterday morning, my sense of smell was anything other than a minor blip!

OK, before I close, I just want to alert all you dear readers to the fact that from later today until early March my son, Alex, is visiting us. His plans are to find somewhere in Oregon to enjoy some skiing but the very mild Winter so far may put a spanner in those works.

For obvious and natural reasons, writing posts for Learning from Dogs will not be a daily high priority. So if you read a number of posts previously published in earlier times you will understand why. Thank you.

One small step at a time

We have absolutely no choice other than to change our ways.

I closed yesterday’s post, Stepping back from the future, with these words:

Tomorrow, I want to offer the example of someone who has been sufficiently strong to take one small step back to sanity.

What I am offering is the reposting of an item in 2013 on Transition Network over in the UK. As you read it, do bear in mind that the references to Amazon are, in the main, to Amazon in the United Kingdom.

The day I closed my Amazon account

Published on December 5, 2013, by Rob Hopkins

I’ve done it. I’ve closed my Amazon account. I now stand before you as an ex-Amazon account-holder. I feel curiously shaky, but at the same time empowered, excited even. While opening a new Amazon account is easy as pie, closing one is another matter altogether. I’d like to share with you how, and why, I did it.

Was it the recent Panorama programme about working conditions in those vast Amazon ‘fulfilment centres’ that tipped me across into doing something? Was it the stories about the appallingly low levels of tax Amazon pay in the UK? Was it the recent video showing Amazon’s plans to be delivering across the UK within 30 minutes through the use of drones? Was it hearing the level of taxpayers’ money that goes in sweeteners to attracting Amazon to open up in different communities, while the profits generated pour out of those same places? What actually tipped me across was a conversation I had with a book seller in my town. It was that that led me, finally, to build the steely resolve needed to close down my Amazon account.

Yes, I confess, I had an Amazon account. I buy music from my local record shop, I support my local book shops, but there are times when I need a book quickly, or feel I do, and it’s just easier and more convenient. And, if I’m honest, I love getting exciting parcels in the post. And isn’t it cheap? But as Carole Cadwalladr, who went undercover in Amazon’s Swansea ‘fulfilment centre’ for The Guardian puts it:

Our lust for cheap, discounted goods delivered to our doors promptly and efficiently has a price. We just haven’t worked out what it is yet.

I’ve always had that nagging conscience that it’s not OK really, but I have just had it ticking away in the background and carried on using it on occasion. The conversation that tipped it for me, with my local bookseller, was around “what would it take for you to stop supporting Amazon?” His example was Primark, recently implicated in child labour in the manufacturing of some its clothes. We know that’s the case, but we still shop there. If we knew that 8 year olds work there, would we stop shopping there? Or 5 year olds? If we knew that every day they arrive for work they get hit with a stick, would we still pop in there for a cheap new shirt? And if they got hit 3 times, and then again in the middle of the day? Where do we draw the line?

Our tendency is to draw a line, but then for that line to slip. What swung it for me was thinking that actually, what I already know should be enough to make me withdraw my support. Also, it was thinking about where the world will be in 5 years time if we continue to give Amazon our support. More and more low paid jobs, with little Union protection, in conditions described in the BBC documentary as “… all the bad stuff at once. The characteristics of this type of job, the evidence shows increased risk of mental illness and physical illness.”

We’ll see Amazon ‘fulfilment centres’ that look like a wasp’s nest, with drones flying in and out. High streets swept clean of bookshops, indeed of most shops, as Amazon spread into selling virtually everything that local economies sell, but far cheaper. It made me think about what kind of a world I’m creating for my sons as they enter the work place. What kind of opportunities will Amazon offer them, as they gut local economies and focus economic activity into vast warehouses along the side of motorways?

I give so much of my time every day to trying to create a different, more just, more resilient world, yet my shopping decisions undermine that. There is also an extraordinary arrogance to thinking that it is OK for you to fill peoples’ airspace, the sky above their heads, with your drones, delivering your products to people for your profit. What happens for a company to get so huge that that is considered acceptable? It is about getting too big. Amazon is too big. Far too big. But it clearly sees that it has only just started. That’s not good.

So, decision made, and with a commitment to source those things in other ways, I went to the website to close my account. Closing an account with Amazon is like breaking up with a girlfriend whose level of obsessive denial is such that the possibility you might want to split up with her doesn’t even enter her consciousness. It’s a fascinating process. Opening an account with Amazon is so easy. Closing an account is, as my 15 year-old son might put it, a right mission.

Click on ‘Your account’ and there is no option anywhere of “Close my account”. Nothing. Like it’s not even a possibility that it might entertain. I had to Google (and don’t get me started on them) “closing your Amazon account”. If you search the Amazon site for “close my account” it yields no results. See below:

The Google link took me to their Help section, on pages that bear the slogan “we’re the people with the smile on the box”, prompting the thought that the inside of their box-like warehouses are probably somewhat bereft of smiles. If offers you a drop-down menu under the helpful title “what can we help you with?”. Surely that’s where I’ll find “Close my Account”? No. You get a range of choices, “An order I placed”, “Kindle”, “Digital services” and, er, “Something else”. Guess I’m “something else” then. So I click that.

I’m then given another 4 options, none of which are “Close my account”. I’m asked to “tell us more about your issue”, and given another list where my option is “other non-order question”. Given that still, the idea that I might have got this far could mean I want to close my account is clearly unimaginable, I am then given an option to email, to phone, or to “chat”. So I click on “chat”, and am told “a customer service associate will be here in a moment”.

A charming man then begins to chat with me. Here’s how our conversation went:

Me: I want to close my account please. How do I do that?

Tom (not his real name): Thank you for contacting Amazon.co.uk. My name is Tom. May I know your name, please?

Me: Rob

Tom: Thank you. I’m sorry to hear that you want to close the account. May I know the reason for closing the account please?

Me: Certainly. I am appalled by the way Amazon operate as highlighted in the recent BBC Panorama programme. I am appalled at the recent story on Amazon considering deliveries in future by drone. I am appalled by the low level of tax Amazon pay in the UK. I have been a customer for years, but I feel Amazon has become too big, and eats everything in its path. It is no longer something I wish to support.

Tom: I’m sorry for the situation. For confidentiality reasons, I’m not able to close your account for you in chat, so I’m going to send you an e-mail with the information to close the account. When you receive it, please respond to that e-mail so that we will close your account.

Me: Thank you Tom. I would really like my reasons for leaving to be registered somehow, as I think a lot more people will be closing their accounts for similar reasons, and it would be good for that to be noted by those in charge. Will that be possible?

Tom: Unfortunately we will not be able to comment on this issue. However, I will send you an email regarding the closing of the account. Is there any thing else I can help you with?

Me: I am not asking you to comment on the issue. I am asking you to make sure that the reasons for my closing my account are passed on to management. If I ran a business I would want to know why my customers were closing their accounts. Is that not the case at Amazon?

Tom: Sure, all the information’s will be recorded and forwarded to the appropriate department.

Me: Thank you Tom. I appreciate your help.

Tom: Thanks for your understanding. We hope to see you again soon! Have a Nice Day!

I later received an email from Customer Support to say:

“We appreciate your feedback and have forwarded it to the appropriate team internally. We are proud to provide a safe and positive working environment for all of our associates. Information about working at our fulfilment centres can be found at the following link: www.amazon.co.uk/fcpractices“

Amazon may be cheap, but cheap comes at a cost for someone else. And, after all, much of what is bought on there is throwaway rubbish. As Carole Cadwalladr puts it:

The warehouse is 800,000 square feet, or, in what is Amazon’s standard unit of measurement, the size of 11 football pitches (its Dunfermline warehouse, the UK’s largest, is 14 football pitches). It is a quarter of a mile from end to end. There is space, it turns out, for an awful lot of crap.

Me, I resolve to buy less, but better. Less, but longer-lasting. Less, but local. The thought of where we will end up in 5 years time, 10 years time, 20 years time, if companies like Amazon continue as they are, really frightens me. It’s not good, it’s not right. It’s not about our needs, it’s about the needs of huge investors. I want a different world for my boys.

I can’t, on my own, do that much about it. I can’t insist that the UK government legislate so that, as in Holland, the Recommended Retail Price (RRP) is the legal minimum at which any book can be sold, although I think that is grounds for a really timely campaign. Because of that, Amazon don’t really operate in Holland. Bring back the RRP for books here, and let’s have a level playing field. As I say, I can’t do much, but I can withdraw my support. I just have withdrawn my support. It feels surprisingly unsettling, as one does after ending a relationship, but it was the right thing to do. It may be a drop in the ocean, but if enough people do it….

ooOOoo

As you might expect, I do have an Amazon account but will look closely into alternatives. In that regard, I just want to expand on the link underneath the earlier phrase, “commitment to source those things in other ways“. The link takes you to an article in the Guardian newspaper, online version, dated the 16th May, 2013. Here are the opening paragraphs:

Amazon’s tax bill is in the news again, after a Guardian investigation put the spotlight on its financial arrangements. There’s a growing swell of people who want to use an alternative place to buy – including my colleague Patrick Collinson who wrote about his attempts to kick the Amazon habit in November.

But it is not always easy to find good alternatives online: if you want to buy either the latest Dan Brown novel (and clearly some people do), Mad Men series five on DVD, or even a packet of Pampers nappies, Amazon seems to come top of the search pages.

That Patrick Collinson piece is a ‘must-read’.

Watch our juicy explainer about the environment’s growing economics problem.

By Sam Bliss on 9 Feb 2015

Consume less, share more. Those are some basic principles behind degrowth, an idea and movement that rejects economic growth as a goal for society. This video explains degrowth with oranges, juice, and peels.

But wait, you ask, isn’t growth a good thing? In an age when we’re conditioned to equate growth with progress, degrowth sounds insane. In reality, pursuing endless exponential expansion of the economy is insane — and impossible. Humans already use resources faster than Earth can replenish them and produce wastes, like carbon emissions, faster than Earth can assimilate them. Hence, degrowth.

Degrowth isn’t about making everyone poorer; it’s about redefining wealth to acknowledge that real well-being can’t be measured in dollars. It’s about breaking down the artificial barrier between life and work; it’s about valuing cooperation over competition; it’s about democracy, autonomy, solidarity, and climate justice. Most importantly, degrowth means sharing society’s surplus for awesome art projects and epic, week-long gatherings.

Check out the vid to get juiced on degrowth.

Sensitivity to the world around us.

The more we give up, the more we ‘own’.

It is a very common, understandable trait of us humans to put our own lives first. I mean that much more in the psychological sense than in the sense of our daily activities although what we think and feel, inevitably, influences how we behave. One of the fabulous qualities of our dogs is that they are so much more sensitive to the world around them than to their own internal thoughts and feelings. Right from the early years of having Pharaoh in my life I was aware that he ‘read’ my emotions easily and soon became an instinctive ‘friend’, especially when I was troubled.

Years later, all of the dogs love it when Jean and I are in happy, positive places and you can see how our human states of mind link so directly to the mood of our dogs.

All of which is my introduction to an essay recently read over on the Big Think blogsite. Specifically, one about living empathically. The essay is called: Let’s Make 2015 “The Year of Living Empathetically” and here are the opening paragraphs:

Let’s Make 2015 “The Year of Living Empathetically”

by JOAN COLE DUFFELL

I began the new year on a very positive – and inspiring – note after reading Eric Liu’s latest commentary on “Radical Empathy”.

The founder and CEO of Citizen University, Liu shows us that laying aside our egos – our need to be in the right – in favor of standing in the shoes of others, is key to addressing so many of the problems that we (once again) confronted in 2014.

This insight – without question – is a wake-up call to our country as 2015 unfolds.

That’s why I think we should resolve to make 2015 “The Year of Living Empathetically.”

We need to make the practice of empathy our New Year’s exercise regimen, our social-emotional diet for the next 365 days.

Let’s practice empathy at home, with our spouses and kids.

Let’s practice empathy in the workplace, as we give and receive feedback, and credit others’ contributions generously.

Let’s practice empathy in the classroom, especially when kids are struggling and need our support.

Let’s practice empathy in public service, as we encounter people who look different from us, and whose lives matter every bit as much as our own.

Let’s practice empathy as we encounter people on the street, who may be less fortunate, and are just as human.

Let’s practice empathy when resolving conflict, whether interpersonally or on a global-political level.

And let’s practice empathy in local and state governments, and in the halls of Congress, so that we might truly listen in order to solve real problems

If all this sounds like a tall order – you’re right; it is.

As Brene Brown, a research professor at the University of Houston Graduate College of Social Work, points out, empathy is a challenging personal choice that requires us to become vulnerable in an effort to connect with another person.

It is not a long essay, so do drop across to here and finish reading it.

As is the way of ideas, serendipity is always actively working ‘under the hood’.

Why do I say that?

Because as soon as I was clear about what I wanted to offer you for today, in to my ‘in-box’ came the latest TED Talk. A talk from Ben Ambridge entitled: 10 myths about psychology: Debunked. It so resonated with today’s theme and is offered below.

http://www.youtube.com/watch?v=ce31WjiVcY0

Published on Feb 4, 2015
How much of what you think about your brain is actually wrong? In this whistlestop tour of dis-proved science, Ben Ambridge walks through 10 popular ideas about psychology that have been proven wrong — and uncovers a few surprising truths about how our brains really work.

Ben Ambridge is the author of “Psy-Q,” a sparkling book debunking what we think we know about psychology.

Why you should listen?

Ben Ambridge is a senior lecturer in psychology at the University of Liverpool, where he researches children’s language development. He is the author of Psy-Q, which introduces readers to some of the major findings in psychology via interactive puzzles, games, quizzes and tests.

He also writes great newsy stories connecting psychology to current events. His article “Why Can’t We Talk to the Animals?” was shortlisted for the 2012 Guardian-Wellcome Science Writing Prize. Psy-Q is his first book for a general audience.
