A Good Samaritan was hiking a narrow, slippery trail on Lookout Mountain in Phoenix, Arizona, and was very focused on his hike until something caught his eye. He was about half a mile up the mountain and a little off the beaten path when he caught a glimpse of light reflecting off of something — and was shocked to realize it was a pair of amber eyes.
The eyes belonged to a very scared dog huddled up in a tiny hole in the side of the mountain. She was completely blending in with her surroundings, and if she hadn’t had such piercing eyes, the hiker may not have noticed her. He had no idea how she’d managed to get up there, but it was clear that she’d been stuck for a while and might not be able to last much longer.
The Good Samaritan quickly contacted the Arizona Humane Society (AHS), who sent two emergency animal medical technicians, Tracey Miiller and Ruthie Jesus, out to help while he waited with the pup until they arrived. The dog was definitely scared but seemed open to getting help.
“This Good Samaritan waited probably almost two hours, and then we found this incredible dog, who incidentally is literally the same color as the dirt,” Jesus said in a press release. “She blends in so much, the complainant told us that he wanted to call her Bright Eyes because when he hiked past her, that was literally the only thing he saw was her amber bright eyes staring back at him.”
After a quick and careful assessment on the side of the mountain, the technicians determined that Bright Eyes was dangerously dehydrated with cut-up paws and a wound on her rear end.
“She was really sweet and letting me pet her head, but she absolutely did not want to come out of that den, so I kind of had to just sort of pull her out,” Jesus said.
She was definitely too weak to walk with her rescuers down the mountain, so the technicians took turns carrying her until they reached the ambulance. Bright Eyes was calm the whole time, so grateful to finally be safe.
“She actually really just relaxed and seemed to enjoy being carried down the mountain,” Jesus said. “But it was a very teeny-tiny rocky trail that was pretty slick, and so Tracey and I took turns carrying her down the mountain, and she was just an absolute angel. She knew we were getting her to safety.”
It’s still a mystery as to how or why Bright Eyes ended up on the mountain in the first place, but the important thing is someone found her and now she’s getting the care she needs.
“We were so elated to be able to get her,” Jesus said. “She was just so dehydrated. I think she’d probably been up there several days and that was probably her last day, and this Good Samaritan really just saved her life.”

Frankly, there’s nothing more to add to this account. For it captured all that so many people do for dogs.
I have no excuse for not being better at looking after my teeth, for one of my elder sisters, Corinne, was a dental assistant and when I was in my mid-fifties I moved down to South-West England and bought a home just a few miles from Corinne’s home. Thereafter she looked after my teeth at the dental practice in Totnes.
But I was careless in following Corinne’s advice and it wasn’t until in my seventies, and living in Merlin, Oregon, that I saw the light; so to speak!

Healthy teeth are wondrous and priceless – a dentist explains why and how best to protect them
Yet, in a society where 1 out of 5 Americans ages 75 and up live without their teeth, many people may not realize that teeth are designed to stay with us for a lifetime.
In the process, I have developed reverence for natural teeth and for the complex beauty of these biological and mechanical masterpieces.
Designed for lifelong function
The secret of teeth longevity lies in their durability as well as in how they are anchored to the jaw – picture a hammer and its hand grip. For each tooth, durability and anchorage are functions of the complex interface between six different tissues; each alone is a biological marvel.
For anchorage, the cementum, ligament and bone grip the tooth at its root portion that is buried under the gum. The ligament, a soft tissue that is about 0.2 millimeters wide (about the diameter of four hairs), attaches the cementum of the root on one end to the bone of the jaw on the other end. It serves to anchor the tooth as well as to cushion its movement during chewing.
For durability, however, the secret lies in the enamel, dentin and pulp – our focus in this discussion.
The enamel is the protective shell that covers the visible part of the tooth above the gum. Thanks to its high mineral content, enamel is the hardest tissue in the body. It needs to be, since it acts as a shield against the constant impact of chewing.
Enamel does not contain cells, blood vessels or nerves, so it is nonliving and nonsensitive. Enamel is also non-regenerating. Once destroyed by decay or broken by misuse such as ice chewing, nail biting or bottle opening – or touched by the dental drill – that part of our priceless enamel is gone for good.
Because it interfaces with a germ-laden world, the enamel is also where decay starts. When acid-generating bacteria accumulate on unbrushed or poorly brushed teeth, they readily dissolve the minerals in the enamel.
How bacteria invade the teeth and cause cavities.
Like hair or fingernails, the non-innervated enamel is not sensitive. The decay advances through the 2.5-millimeter thick (tenth of an inch) layer of enamel painlessly. When caught at that phase during a dental checkup visit, the dentist can treat the decay with a relatively conservative filling that hardly compromises the tooth’s structural integrity.
Because of its high mineral content, enamel is stiff. Its lifelong support is provided by the more resilient infrastructure – the dentin.
Dentin and pulp – body and heart
With less mineral content than enamel, dentin is the resilient body of the tooth. It is a living tissue formed of parallel tiny tubes housing fluid and cellular extensions. Both originate from the pulp.
The pulp is the tooth’s soft tissue core. Vastly rich in cells, blood vessels and nerves, it is the life source of the tooth – its heart – and the key to its longevity.
Like smoke detectors communicating with a remote fire station, the cellular extensions within the dentin sense decay as soon as it breaks through the nonsensitive layer of enamel into dentin. Once the extensions communicate the danger signal to the pulp, our tooth sensitivity alarm goes off: The tooth heart is in flames.
The inflamed pulp initiates two protective actions. The first is to secrete an additional layer of dentin to delay the approaching attack. The second is toothache, a call to visit the dentist.
The earlier the visit, the less the drilling and the smaller the filling. If caught in time, most of the tooth’s natural tissues will be preserved and the pulp will likely regain its healthy state. If caught too late, the pulp slowly dies out.
Without its heart, a nonliving tooth has no defense against further decay invasion. Without a hydration source, a dried-out dentin will sooner or later break under the forces of constant chewing. Besides, a tooth that has already lost a significant portion of its natural structure to decay, cavity preparation or root canal instrumentation becomes weak, with limited longevity.
In other words, the tooth is never the same without its heart. Pulpless, the tooth loses its womb-to-tomb endurance and mother nature’s lifelong warranty.
The tooth coming together
More complex – and more precious – than a pearl within an oyster, the formation of a tooth within our jawbone involves layered mineral deposition. As tooth development progresses in a process of ultimate cellular engineering, the cells of the six aforementioned tissues – enamel, dentin, pulp, cementum, ligament and bone – multiply, specialize and mineralize synchronously with each other to form uniquely interlocking interfaces: enamel to dentin, dentin to pulp, cementum to dentin and cementum to ligament to bone.
In a progress akin to 3D printing, the tooth crown grows vertically to full formation. Simultaneously, the root continues its elongation to eventually launch off the crown from within the bone across the gum to appear in the mouth – the event known as teething. It is about that time, around 12 years of age, that our set of adult teeth is complete. These pearls are set to endure a lifetime and are undoubtedly worth preserving.
Save your teeth, visit the dentist
Tooth decay, the most prevalent disease in humans, is both predictable and preventable. The earlier it is caught, the more the tooth integrity can be preserved. Since the process starts painlessly, it is imperative to visit the dentist regularly to keep those insidious germs in check.
During your checkup visit, the dental professional will clean your teeth and check for early decay. If you are diligent with your daily preventive measures, the good news for you will be no news – enough to make anyone smile.
Recently, staff at the Wyandotte Animal Shelter in Michigan took in a dog whose condition was described as among the worst they’d ever seen. Pixie, as the dog is named, had fur so overgrown and matted that she could hardly move.
Gazing upon Pixie, one might never guess that an adorable dog existed beneath it.
Wyandotte Animal Shelter
According to staff at the shelter, Pixie was surrendered by her owner, who, regrettably, had neglected to give her the care and attention she needed — leading to her severely unkempt condition. Ultimately, though, his decision to surrender her is what Pixie needed most.
“He had a hard time letting her go but surrendered her to us so we could ensure she would go to someone who could give her the life she deserved,” the shelter wrote.
With that, Pixie’s world was about to change forever — and it would have to start with a much-needed haircut.
Wyandotte Animal Shelter
Staff at the shelter reached out to The Downriver Grooming Co. for what would be an emergency grooming session to help Pixie escape from her matted prison.
“[They got] her in within minutes of our call, and for [three] hours they spent freeing her from that matted fur,” the shelter wrote.
Wyandotte Animal Shelter
After all was said and done, the real Pixie had emerged.
She was totally unrecognizable from her former self.
Wyandotte Animal Shelter
“This little girl was only 5.5 pounds, but she seemed twice her size due to the matted fur,” the shelter wrote, adding that she was in remarkably good health, despite her ordeal beneath that overgrown coat.
Pixie’s world had changed for the better — but it wouldn’t be long until it improved even more.
Wyandotte Animal Shelter
Within days of Pixie’s transformation, thanks to the kindness of those who’d helped her, the little dog got the second chance she so desperately needed.
“Pixie was adopted,” a spokesperson for the Wyandotte Animal Shelter told The Dodo. “Her new family reports that she is doing very well in her new home.”

We all need second chances from time to time, humans and dogs.
Although I was born in London in 1944, as a result of an affair between my father and mother, my father had two daughters with his wife, Maud, and Rhona and Corinne, for they were their names, took me under their wing. In the 50s Maud, Rhona and Corinne all moved to Devon and I started going regularly to Totnes. When I started driving I usually stopped for a break close by Stonehenge so the site has a special interest to me.
So when I saw this article in The Conversation it had to be shared.

Stonehenge may have aligned with the Moon as well as the Sun
When it comes to its connection to the sky, Stonehenge is best known for its solar alignments. Every midsummer’s night tens of thousands of people gather at Stonehenge to celebrate and witness the rising Sun in alignment with the Heel stone standing outside of the circle. Six months later a smaller crowd congregates around the Heel stone to witness the midwinter Sun setting within the stone circle.
But a hypothesis has been around for 60 years that part of Stonehenge also aligns with moonrise and moonset at what is called a major lunar standstill. Although a correlation between the layout of certain stones and the major lunar standstill has been known about for several decades, no one has systematically observed and recorded the phenomenon at Stonehenge.
This is what we are aiming to do in a project bringing together archaeologists, astronomers and photographers from English Heritage, Oxford, Leicester and Bournemouth universities as well as the Royal Astronomical Society.
There is now an abundance of archaeological evidence that indicates the solar alignment was part of the architectural design of Stonehenge. Around 2500 BC, the people who put up the large stones and dug an avenue into the chalk seemed to want to cement the solstice axis into the architecture of Stonehenge.
Archaeological evidence from nearby Durrington Walls, the place where scientists believe the ancient people who visited Stonehenge stayed, indicates that of the two solstices it was the midwinter one that drew the largest crowd.
But Stonehenge includes other elements, such as 56 pits arranged in a circle, an earthwork bank and ditch, and other smaller features such as the four station stones. These are four sarsen stones, a form of silicified sandstone common in Wiltshire, that were carefully placed to form an almost exact rectangle encompassing the stone circle.
Only two of these stones are still there, and they pale in comparison to their larger counterparts as they are only a few feet high. So what could their purpose be?

Lunar standstill
The rectangle that they form is not just any rectangle. The shorter sides are parallel to the main axis of the stone circle and this may be a clue as to their purpose. The longer sides of the rectangle skirt the outside of the stone circle.
It is these longer sides that are thought to align with the major lunar standstill. If you marked the position of moonrise (or set) over the course of a month you would see that it moves between two points on the horizon. These southern and northern limits of moonrise (or set) change on a cycle of 18.6 years between a minimum and a maximum range – the so-called minor and major lunar standstills, respectively.
The major lunar standstill is a period of about one and a half to two years when the northernmost and southernmost moonrises (or sets) are furthest apart. When this happens the Moon rises (and sets) outside the range of sunrises and sets, which may have imbued this celestial phenomenon with meaning and significance.

The strongest evidence we have for people marking the major lunar standstill comes from the US southwest. The Great House of Chimney Rock, a multi-level complex built by the ancestral Pueblo people in the San Juan National Forest, Colorado, more than 1,000 years ago.
It lies on a ridge that ends at a natural formation of twin rock pillars – an area that has cultural significance to more than 26 native American tribal nations. From the vantage point of the Great House, the Sun will never rise in the gap between the pillars.
However, during a major standstill the Moon does rise between them in awe-inspiring fashion. Excavations unearthed preserved wood that meant researchers could date to the year episodes of construction of the Great House.
Of six cutting dates, four correspond to major lunar standstill years between the years AD1018 and AD1093, indicating that the site was renewed, maintained or expanded on consecutive major standstills.
Returning to southern England, archaeologists think there is a connection between the major lunar standstill and the earliest construction phase of Stonehenge (3000-2500 BC), before the sarsen stones were brought in.
Several sets of cremated human remains from this phase of construction were found in the southeastern part of the monument in the general direction of the southernmost major standstill moonrise, where three timber posts were also set into the bank. It is possible that there was an early connection between the site of Stonehenge and the Moon, which was later emphasised when the station stone rectangle was built.
The major lunar standstill hypothesis, however, raises more questions than it answers. We don’t know if the lunar alignments of the station stones were symbolic or whether people were meant to observe the Moon through them. Neither do we know which phases of the Moon would be more dramatic to witness.
A search for answers
In our upcoming work, we will be trying to answer the questions the major lunar standstill hypothesis raises. It’s unclear whether the Moon would have been strong enough to cast shadows and how they would have interacted with the other stones. We will also need to check whether the alignments can still be seen today or if they are blocked by woods, traffic and other features.
The Moon will align with the station stone rectangle twice a month from about February 2024 to November 2025, giving us plenty of opportunities to observe this phenomenon in different seasons and phases of the Moon.
To bring our research to life, English Heritage will livestream the southernmost Moonrise in June 2024, and host a series of events throughout the year, including talks, a pop-up planetarium, stargazing and storytelling sessions.
Across the Atlantic, our partners at the US Forest Service are developing educational materials about the major lunar standstill at Chimney Rock National Monument. This collaboration will result in events showcasing and debating the lunar alignments at both Stonehenge and at Chimney Rock.
I came across this post yesterday and thought that it would make a good article for today. But the truth is that I, and I expect many other readers, do not understand the article.

Employees Heartbroken When They See Someone Tied To ‘Do Not Abandon Animals’ Sign
Outside the front door of the Harbor Humane Society sits a sign. “Do not abandon an animal here,” the sign reads. “Wait until business hours. No fee for bringing an animal to HHS. For the sake of the animal, please be humane.” An older, outdated version of the same sign sits at the back of the shelter, too, near some picnic tables where employees can take a break. When they arrived at work one morning recently, there were no animals waiting for them out front.
Harbor Humane Society
Sadly, the same could not be said for the sign in the back.
Tied to the base of the “do not abandon animals” sign was a tiny dog who had been abandoned there the night before. Security footage showed the dog, later named Trixie, had been tied to the sign around 9 p.m. and wasn’t found until 7:30 a.m. the next morning, meaning she’d waited there for 11 hours.
Harbor Humane Society
“Our team member was just about to unarm the building (had just arrived to start their morning shift) when she noticed the dog tied to the signpost near our intake door located toward the back side of the shelter,” Jen Nuernberg, director of marketing and strategic initiatives at Harbor Humane Society, told The Dodo. “Initially, she was nervous and scared, barking at her. But once she crouched down and gave her some time, she quickly warmed up and crawled right into her lap. She has been very friendly ever since!”
Harbor Humane Society
Trixie was terrified out there all alone, wondering why she’d ended up there. As soon as she met her rescuer, though, all was well. She was rushed inside and eventually met the rest of the staff members, who were just as heartbroken by the situation. Thankfully, Trixie seemed to be pretty healthy, just a little confused — as was everyone at the shelter.
“When someone abandons an animal without any information, we are just left to guess,” Jen Self Aulgur, executive director at Harbor Humane Society, told The Dodo. “So we can assume she is about 3 to 4 years old, but we don’t know her story, her name, her likes, her favorite treats or toys. This is all information we try to get on animals when they are surrendered to the shelter.”
Harbor Humane Society
The shelter employees are still hoping someone might come forward to give them some information about Trixie before she’s adopted, just to make sure she’s getting the best care possible.
“This pup deserves to have her story and history known,” Self Aulgur said. “We do not want to shame or get you in trouble — we just want to help this poor pup.”
Harbor Humane Society
Trixie is safe now and will be available for adoption in about a week or so. Until then, she’s getting as many kisses and cuddles as the staff can give her while she dreams of her loving forever family.
ooOOoo
Let me add my wishes to the Harbor Humane Society in hoping that very soon Trixie will be adopted by that loving family.
There were so many things that I could have written about for today but they were all swept aside by an email that came in from an old friend of mine, Chris Snuggs.
Chris and I go back many years to the time when I was a visiting teacher at Isuga in France.
But the point of this post is to share the video that Chris provided about Julie Christie. Here is the first part of a WikiPedia article:
A riveting history of counting and calculating from the time of the cave dwellers to the late twentieth century, The Universal History of Numbers is the first complete account of the invention and evolution of numbers the world over. As different cultures around the globe struggled with problems of harvests, constructing buildings, educating their citizens, and exploring the wonders of science, each civilization created its own unique and wonderful mathematical system.
Dubbed the “Indiana Jones of numbers,” Georges Ifrah traveled all over the world for ten years to uncover the little-known details of this amazing story. From India to China, and from Egypt to Chile, Ifrah talked to mathematicians, historians, archaeologists, and philosophers. He deciphered ancient writing on crumbling walls; scrutinized stones, tools, cylinders, and cones; and examined carved bones, elaborately knotted counting strings, and X-rays of the contents of never-opened ancient clay accounting balls. Conveying all the excitement and joy of the process of discovery, Ifrah writes in a delightful storytelling style, recounting a plethora of intriguing and amusing anecdotes along the way.
Now to that article on The Conversation.

From thousands to millions to billions to trillions to quadrillions and beyond: Do numbers ever end?
Why don’t numbers end? – Reyhane, age 7, Tehran, Iran
Here’s a game: Ask a friend to give you any number and you’ll return one that’s bigger. Just add “1” to whatever number they come up with and you’re sure to win.
The reason is that numbers go on forever. There is no highest number. But why? As a professor of mathematics, I can help you find an answer.
First, you need to understand what numbers are and where they come from. You learned about numbers because they enabled you to count. Early humans had similar needs – whether to count animals killed in a hunt or keep track of how many days had passed. That’s why they invented numbers.
But back then, numbers were quite limited and had a very simple form. Often, the “numbers” were just notches on a bone, going up to a couple hundred at most.
How numbers evolved throughout the centuries.
When numbers got bigger
As time went on, people’s needs grew. Herds of livestock had to be counted, goods and services traded, and measurements made for buildings and navigation. This led to the invention of larger numbers and better ways of representing them.
About 5,000 years ago, the Egyptians began using symbols for various numbers, with a final symbol for one million. Since they didn’t usually encounter bigger quantities, they also used this same final symbol to depict “many.”
The Greeks, starting with Pythagoras, were the first to study numbers for their own sake, rather than viewing them as just counting tools. As someone who’s written a book on the importance of numbers, I can’t emphasize enough how crucial this step was for humanity.
But there was a problem. Although the Greeks could mentally think of very large numbers, they had difficulty writing them down. This was because they did not know about the number 0.
Think of how important zero is in expressing big numbers. You can start with 1, then add more and more zeroes at the end to quickly get numbers like a million – 1,000,000, or 1 followed by six zeros – or a billion, with nine zeros, or a trillion, 12 zeros.
This brief history makes clear that numbers were developed over thousands of years. And though the Egyptians didn’t have much use for a million, we certainly do. Economists will tell you that government expenditures are commonly measured in millions of dollars.
Also, science has taken us to a point where we need even larger numbers. For instance, there are about 100 billion stars in our galaxy – or 100,000,000,000 – and the number of atoms in our universe may be as high as 1 followed by 82 zeros.
Don’t worry if you find it hard to picture such big numbers. It’s fine to just think of them as “many,” much like the Egyptians treated numbers over a million. These examples point to one reason why numbers must continue endlessly. If we had a maximum, some new use or discovery would surely make us exceed it.
The symbols of math include +, -, x and =.
Exceptions to the rule
But under certain circumstances, sometimes numbers do have a maximum because people design them that way for a practical purpose.
A good example is a clock – or clock arithmetic, where we use only the numbers 1 through 12. There is no 13 o’clock, because after 12 o’clock we just go back to 1 o’clock again. If you played the “bigger number” game with a friend in clock arithmetic, you’d lose if they chose the number 12.
Since numbers are a human invention, how do we construct them so they continue without end? Mathematicians started looking at this question starting in the early 1900s. What they came up with was based on two assumptions: that 0 is the starting number, and when you add 1 to any number you always get a new number.
These assumptions immediately give us the list of counting numbers: 0 + 1 = 1, 1 + 1 = 2, 2 + 1 = 3, and so on, a progression that continues without end.
You might wonder why these two rules are assumptions. The reason for the first one is that we don’t really know how to define the number 0. For example: Is “0” the same as “nothing,” and if so, what exactly is meant by “nothing”?
The second might seem even more strange. After all, we can easily show that adding 1 to 2 gives us the new number 3, just like adding 1 to 2002 gives us the new number 2003.
But notice that we’re saying this has to hold for any number. We can’t very well verify this for every single case, since there are going to be an endless number of cases. As humans who can perform only a limited number of steps, we have to be careful anytime we make claims about an endless process. And mathematicians, in particular, refuse to take anything for granted.
Here, then, is the answer to why numbers don’t end: It’s because of the way in which we define them.
Now, the negative numbers
How do the negative numbers -1, -2, -3 and more fit into all this? Historically, people were very suspicious about such numbers, since it’s hard to picture a “minus one” apple or orange. As late as 1796, math textbooks warned against using negatives.
The negatives were created to address a calculation issue. The positive numbers are fine when you’re adding them together. But when you get to subtraction, they can’t handle differences like 1 minus 2, or 2 minus 4. If you want to be able to subtract numbers at will, you need negative numbers too.
A simple way to create negatives is to imagine all the numbers – 0, 1, 2, 3 and the rest – drawn equally spaced on a straight line. Now imagine a mirror placed at 0. Then define -1 to be the reflection of +1 on the line, -2 to be the reflection of +2, and so on. You’ll end up with all the negative numbers this way.
As a bonus, you’ll also know that since there are just as many negatives as there are positives, the negative numbers must also go on without end!
Hello, curious kids! Do you have a question you’d like an expert to answer? Ask an adult to send your question to CuriousKidsUS@theconversation.com. Please tell us your name, age and the city where you live.

This article was written for those a great deal younger than I am. But, to be honest, it is a fascinating account of something so utterly basic to humans and human cognition.
I shall be 80 in November and I find myself thinking about death more often than I did a few years ago. As an example of how my mind has changed, yesterday I was contemplating renewing my subscription to the Free Inquiry magazine and wondering if I should renew it for two or three years? In other words will I still be alive in three years time? Silly but it is the truth. And that is not taking into account that I go to the Club Northwest two days a week and try and bike ride another two or three times a week.
Then let us not get into the topic of whether I will die before Jean or the reverse. That is an enormous subject and, thank goodness, where we live in Oregon one has the choice to die: “Two states, Oregon and Washington, currently have statutes providing a procedure for a terminally ill patient to request medication to end his or her life. These laws are sometimes referred to as “death with dignity” or “physician-assisted suicide” laws.“
All of which is an introduction to a recent article published in The Conversation that I republish below:

Loneliness can kill, and new research shows middle-aged Americans are particularly vulnerable
Middle-aged Americans are lonelier than their European counterparts. That’s the key finding of my team’s recent study, published in American Psychologist.
Our study identified a trend that has been evolving for multiple generations, and affects both baby boomers and Gen Xers. Middle-aged adults in England and Mediterranean Europe are not that far behind the U.S. In contrast, middle-aged adults in continental and Nordic Europe reported the lowest levels of loneliness and stability over time.
We used survey data drawn from over 53,000 middle-aged adults from the U.S. and 13 European nations from 2002 to 2020. We tracked their reported changes in loneliness every two years across the midlife years of 45 to 65. This span provided us data from the so-called silent generation of people born between 1937 and 1945; baby boomers, born between 1946 and 1964; and members of Generation X, born between 1965 and 1974.
Our study makes clear that middle-aged Americans today are experiencing more loneliness than their peers in European nations. This coincides with existing evidence that mortality rates are rising for working-age adults in the U.S.
We focused on middle-aged adults for several reasons. Middle-aged adults form the backbone of society by constituting a majority of the workforce. But they also face increasing challenges today, notably greater demands for support from both their aging parents and their children.
Loneliness is considered a global public health issue. The U.S. surgeon general released an advisory report in 2023 documenting an epidemic of loneliness and a pressing need to increase social connection. Other nations, such as the U.K.and Japan, have appointed ministers of loneliness to ensure relationships and loneliness are considered in policymaking.
You can be lonely even when surrounded by people.
What still isn’t known
Why are middle-aged Americans exceptional when it comes to loneliness and poorer overall mental and physical health?
We did not directly test this in our study, but in the future we hope to zero in on the factors driving these trends. We think that the loneliness Americans are reporting compared to peer nations comes down to limited social safety nets and to cultural norms that prioritize individualism over community.
Individualization carries psychological costs, such as reductions in social connections and support structures, which are correlates of loneliness. Relative to the other nations in our study, Americans have a higher tendency to relocate, which is associated with weak social and community ties.
One of the reasons why we chose countries from across Europe is that they differ dramatically from the U.S. when it comes to social and economic opportunities and social safety nets. Social and economic inequalities likely increase one’s loneliness through undermining one’s ability to meet basic needs. Generous family and work policies likely lessen midlife loneliness through reducing financial pressures and work-family conflict, as well as addressing health and gender inequities.
Our findings on loneliness in conjunction with previous studies on life expectancy, health, well-being and cognition suggest that being middle-aged in America is a risk factor for poor mental and physical health outcomes.
The Research Brief is a short take on interesting academic work.
And on yesterday afternoon, the Sunday, I went for a bike ride of 22 miles. I loved the ride especially as I listened to music all the way; I have a portable speaker that clips near the front handlebars and plays tracks from my iPhone.
Then there was an article in March from the University of Bristol: “Happiness can be learnt, but we have to work at it – study finds.“
It reads:
Press release issued: 11 March 2024
We can learn to be happy, but only get lasting benefits if we keep practising, a first-of-its-kind study has revealed.
The team behind the University of Bristol’s ‘Science of Happiness’ course had already discovered that teaching students the latest scientific studies on happiness created a marked improvement in their wellbeing.
But their latest study found that these wellbeing boosts are short-lived unless the evidence-informed habits learnt on the course – such as gratitude, exercise, meditation or journaling – are kept up over the long-term.
Senior author Professor Bruce Hood said: “It’s like going to the gym – we can’t expect to do one class and be fit forever. Just as with physical health, we have to continuously work on our mental health, otherwise the improvements are temporary.”
Launched in 2018, the University of Bristol’s Science of Happiness course was the first of its kind in the UK. It involves no exams or coursework, and teaches students what the latest peer-reviewed studies in psychology and neuroscience say really makes us happy.
Students who took the course reported a 10 to 15% improvement in wellbeing. But only those who continued implementing the course learnings maintained that improved wellbeing when they were surveyed again two years on.
Published in the journal Higher Education, it is the first to track wellbeing of students on a happiness course long after they have left the course.
Professor Hood said: “This study shows that just doing a course – be that at the gym, a meditation retreat or on an evidence-based happiness course like ours – is just the start: you must commit to using what you learn on a regular basis.
“Much of what we teach revolves around positive psychology interventions that divert your attention away from yourself, by helping others, being with friends, gratitude or meditating.
“This is the opposite of the current ‘selfcare’ doctrine, but countless studies have shown that getting out of our own heads helps gets us away from negative ruminations which can be the basis of so many mental health problems.”
Professor Hood has distilled the Science of Happiness course into a new book, out on March 10. ‘The Science of Happiness: Seven Lessons for Living Well’ reveals an evidence-informed roadmap to better wellbeing.
The other paper authors are fellow University of Bristol academics Catherine Hobbs and Sarah Jelbert, and Laurie R Santos, a Yale academic whose course inspired Bristol’s Science of Happiness course.
