Welcome!

Beloved Pharaoh. Born: June 3rd., 2003 – Died: June 19th., 2017. A very special dog that will never be forgotten.

Dogs live in the present – they just are!  Dogs make the best of each moment uncluttered by the sorts of complex fears and feelings that we humans have. They don’t judge, they simply take the world around them at face value.  Yet they have been part of man’s world for an unimaginable time, at least 30,000 years.  That makes the domesticated dog the longest animal companion to man, by far!

As man’s companion, protector and helper, history suggests that dogs were critically important in man achieving success as a hunter-gatherer.  Dogs ‘teaching’ man to be so successful a hunter enabled evolution, some 20,000 years later, to farming,  thence the long journey to modern man.  But in the last, say 100 years, that farming spirit has become corrupted to the point where we see the planet’s plant and mineral resources as infinite.  Mankind is close to the edge of extinction, literally and spiritually.

Dogs know better, much better!  Time again for man to learn from dogs!

How You Can Make a Real Difference for Shelter and Rescue Pets

Busy parents juggling work and school pickups, local business owners trying to stay visible, and animal lovers who can’t bring home another pet often care deeply about local animal welfare but feel stuck between compassion and capacity. Shelters and rescues don’t run on good intentions alone; they rely on community support for shelter pets to keep care consistent and outcomes hopeful. When that support is thin, animals wait longer, stress rises, and the whole community feels the strain. The encouraging part is that animal shelter volunteers, pet rescue awareness, and understanding the real rescue pet adoption benefits can turn everyday concern into steady, meaningful impact.

Understanding What “Supporting Rescue Pets” Means

Shelter and rescue support is the hands-on help that keeps animals safe, calm, and adoptable while they wait for a home. In practice, it usually means fostering for a short window, volunteering time and skills, or giving targeted donations that cover food, vet care, and transport.

This matters because small, steady support shortens an animal’s road from intake to adoption. The need is constant since 2.8 million dogs and cats entered U.S. shelters in just the first half of 2025. Foster care helps too, and studies by the ASPCA show dogs in foster spend less time waiting for permanent homes.

Think of it like a relay team: one person handles weekend fostering, another covers a Tuesday walk shift, and a third funds vaccines. Together, those pieces reduce stress, prevent crowding, and make adoption feel more doable. Clear, consistent visuals can amplify that support when you share adoptable pets and campaigns.

Make Scroll-Stopping Adoption and Fundraiser Images in Minutes

Once you understand what rescue support looks like day to day, it’s easier to see why clear, consistent visuals can be a quiet force-multiplier for everything else. AI-generated visuals can help you create compelling images for adoption campaigns, fundraising posts, and educational materials that raise awareness and spark community support for pets in need. 

One especially handy approach is using an AI image-to-image generator, which starts with a reference photo you already have and then uses your written prompts to guide the creative output into new styles or variations. That means the same pet can be shown in different looks, while still staying recognizable, so your outreach graphics feel cohesive, readable, and shareable across social platforms and print. If you’re curious how this works in practice, Adobe Firefly is one example of an image-to-image tool that demonstrates the idea.

Choose High-Impact Ways to Help—Time, Space, or Money

You don’t have to do everything to make a real difference, you just need to choose a few actions that fit your life right now. Pick one from “time,” “space,” or “money,” and you’ll quickly become the kind of supporter shelters can count on.

  1. Foster one pet for a defined window: Ask a shelter about “weekend foster,” “two-week decompression,” or “foster-to-adopt” options so you can say yes without overcommitting. Fostering gets pets out of the noisy kennel environment and into a home routine, which often improves adoptability, one analysis of the foster care model reports better outcomes compared to traditional shelter housing. To make it sustainable, clarify who provides food, meds, crates, and what to do after-hours if something feels urgent.
  2. Offer temporary pet care for crisis moments: Many shelters and rescues need short-term help for pets whose owners are hospitalized, displaced, or escaping unsafe situations. Volunteer to cover 24–72 hours, a week, or “day boarding” while paperwork and placements are arranged. This is a great option if you can’t foster long-term but you can handle a short burst of responsibility.
  3. Volunteer in a role that matches your energy, not just your heart: If you love people, help with adoption counseling, event check-in, or donation sorting. If you prefer animals, sign up for dog walking, cat socialization, enrichment prep, or transport runs to vet appointments. Ask for a consistent shift (even 2 hours every other week) so staff can schedule around you and you build real skill.
  4. Become a “quiet helper” from home: Many rescues need behind-the-scenes support like answering messages, updating pet bios, building simple spreadsheets, calling vet clinics, or writing thank-you notes to donors. This is also where those scroll-stopping graphics matter: offer to turn a pet’s best photo into a clean adoption post, a “supply drive needs” image, or a mini success-story carousel people will actually share.
  5. Donate strategically, fill the gap, not the pile: Before buying anything, check the shelter’s wish list or ask, “What do you run out of every week?” Most places consistently need consumables like kitten formula, canned food, laundry detergent, paper towels, and enrichment items, plus gift cards for emergencies. If you want your dollars to stretch, offer to sponsor one specific cost (a vaccine day, a spay/neuter deposit, a heartworm test fund) and ask them what amount is most useful.
  6. Use your space for micro-logistics: If your home can’t take a foster pet, it might be perfect for holding donated supplies, assembling adoption packets, or staging a “pop-up pantry” for families who need short-term pet food help. Even one closet or a spare corner of a garage can smooth out the chaos between donation drop-offs and distribution.
  7. Organize a small, repeatable adoption event: Partner with a rescue to host a two-hour meet-and-greet at a community spot that already has foot traffic, like a café patio, hardware store garden area, or office courtyard. Offer to handle the simple pieces: a sign-up sheet, clear “ask me about adopting” badges, water bowls, and a few consistent photo backdrops so every pet goes home with a great shareable image.
  8. Recruit one friend and make it easy for them to say yes: People are far more likely to help when the task is specific: “Can you walk dogs this Saturday 10–12?” beats “We should volunteer sometime.” If you’re trying to build a volunteer bench, it helps to know 25% of Gen Z are actively volunteering, so asking students, interns, or early-career coworkers can be surprisingly effective.
  9. Help pets stand out with better bios and adoption follow-up: Pick one animal and improve their listing: 5 clear photos, 3 personality adjectives, 3 “loves,” 1 training note, and 1 ideal-home match. Offer adopters a simple handoff sheet with routine, food, favorite toys, and how to contact the rescue for support. Better expectations reduce returns and help the adoption stick.
  10. Commit to a “one-month impact plan”: Choose one action for each week, one shift, one foster weekend, one supply run, one post-and-share sprint, then repeat what worked. Consistency is what turns good intentions into saved lives, and it also makes it easier to decide when fostering, volunteering, or donating feels like the right next step for you.

Common Questions About Helping Shelter Pets

Q: How do I start fostering if I’ve never done it before?
A: Call or email a shelter and ask what short-term options they offer and what supplies they provide. Request a clear handoff: food, meds, crate needs, and who to contact after hours. A foster coordinator can also match you with an easier pet for a first run.

Q: What are the hardest parts of volunteering, and how do I avoid burning out?
A: The biggest challenges are emotional ups and downs and schedules that shift when the shelter gets busy. Choose one role and one repeating time slot you can protect, even if it is small. If you feel overwhelmed, ask to switch to a lighter duty like laundry, enrichment prep, or admin help.

Q: How do shelter donations usually work, and what’s most helpful?
A: Many groups sort donations by immediate use, storage space, and safety rules, so unrequested items can create extra work. Cash or gift cards often help cover urgent medical needs, especially since rising cost of veterinary care can affect adoptions and drive surrenders. If you prefer shopping, ask for a current wish list and stick to it.

Q: What basic legal things should adopters expect to sign or follow?
A: Most adoptions include a contract that covers fees, return policies, and required care like licensing or vaccinations. Read it carefully, ask what support is available if issues come up, and confirm what happens if the pet is not a fit. Keep copies of your agreement and medical records in one folder.

Q: Can fostering really change outcomes, or is it just a temporary fix?
A: It can be a big driver of success because it gives pets a calmer place to reset and show their true personality. A 30% higher adoption rate has been found at shelters with a full foster program. Even one short foster can free kennel space and help a pet get noticed.

Choose One Consistent Way to Support Shelter and Rescue Pets

Wanting to help is easy; figuring out how to fit it into a busy life, and keep going when it gets emotional, is the hard part. The most reliable approach is simple: choose one doable lane and lean into long-term shelter support through steady community involvement in animal rescue. Over time, that consistency means making a positive impact for pets with fewer disruptions and more second chances. Small, steady help saves lives. Pick one next step today, sign up for an orientation, commit to a regular shift, or set a monthly donation, and stick with it. That ongoing volunteering and follow-through is what turns ordinary people into empowered pet rescue advocates and gives shelters the stability to keep showing up, too.

If this inspires just one person to support their local shelter then I’m certain Penny (and me) will be honoured.

A Very Positive Message

The poetry of the young.

Last Saturday, I was going through my inbox and reading the new emails. I subscribe to The Conversation and in the articles of the 25th June was the following.

Now the article speaks of American youngsters but my guess is that in many other countries the young are similarly positive.

ooOOoo

I have spent the past 6 months reading hundreds of poems by young people – I was surprised to find hope, not despair

If you’ve read any commentary about younger people, none of the following statistics will surprise you.

Approximately 19% of Americans who are 12 to 19 years old are depressed – higher than any adult age group. Only about 58.5% of teens who are 12 to 17, meanwhile, say they consistently receive the emotional and social support they need. They often have little faith in institutions – be it the government or schools, or one another. And the average American child age 8 to 18 spends 7.5 hours a day watching or using screens.

On the one hand, these statistics are understandable: Young people are facing a future shaped by climate anxiety, political extremism, economic instability and chronic loneliness.

But those numbers may only be telling part of the story.

I have spent the past six months reading hundreds of poems submitted by young writers age 10 to 21. In June 2026, we will publish an anthology of writing from 177 of these young people in the “1455 Young Poets Anthology.”

More than 300 young people submitted their poems to a nonprofit I run, called 1455 Storytelling Arts. The poets mostly come from the U.S., but nine other countries are represented.

I continually found myself surprised, encouraged and inspired while reading their poetry. In a world that sometimes seems to reward the noisiest and the most aggressive, the wealthiest and the most selfish, these young poets understand something at once simple and profound that I think many adults have forgotten: Hope is not optimism. It’s endurance.

Small photos of young people are seen in two rows, with their names underneath.

‘The only way through is through’

For the young writers whose work crossed my desk, hoping for a better future seems to be both a personal and collective act of accountability. It’s a refusal to accept a status quo in politics and other ways of life that might not work for some people.

Again and again, young people submitted poems that wrestled with loneliness, fractured families, violence, identity, anxiety, grief and uncertainty.

Layla Dwelle, age 15, confronts this tense atmosphere of information overload and anxiety, writing, “I’m tired of the cycle / I’m tired of evil / I’m tired of what is done / I’m tired of what isn’t.”

Yet many also revealed an unwillingness to surrender entirely to despair. Alicia Chow, age 14, writes, “I realize the only way through is through / So I keep moving as defiance of loss.”

These poems acknowledge pain, but identify tenderness in the darker corners of life. They describe a world that has a soundtrack set on two extremes: chaos and silence. They grapple with real fear and insist that bearing witness to the world gives purpose and meaning to people’s lives.

These writers, in short, are not giving up – they are looking to create a future that revises the dysfunctional present, which they see as a work in progress.

The titles of some poems speak volumes about the worlds and feelings these poems explore: “Self-Portrait as a Firefly,” “The Cost of Rain,” “The Ones Who Run,” “Prayer for a New Season,” “The Grass That Grows in the Cracks” and “Scars on Soul.”

Where reality meets urgency

What struck me most while editing this anthology was not the poets’ honesty or vulnerability, though both of those qualities were present.

Instead, it was their maturity that really stood out. There’s a focused seriousness present in their writing that combines political reality with a sense of urgency.

Here’s Emily Bennett, age 18, from her poem, “For the Love of the Sunk Cost Fallacy”:

Because,
nothing true aches forever.
And sometimes the bravest thing
you can do is simply open your hands.

Many of these young writers are trying to answer questions that adults themselves struggle with or avoid, including how to remain human in a culture that monetizes distraction.

This is an issue the American writer Jenny Odell compellingly addresses in her 2019 book, “How to Do Nothing: Resisting the Attention Economy.” Her thesis, simple yet radical, is that attention is people’s most vital resource, and all people are being bombarded, 24/7, with algorithmic strategies looking to distract and divide them. She astutely describes “the mindless traffic of information,” which, not so coincidentally, is something poetry has always stood in quiet defiance of.

The poems raise other questions. How do people care for one another without becoming uncomfortably numb to others’ pain and suffering? How do people imagine and create a future while they are constantly reminded of growing inequality within many countries, and with the world’s wealthiest people quickly growing richer?

The fact that so many young people are still turning to poetry feels, to me, significant, if not momentous.

Poetry is typically not a commercially rewarded art form. It obliges readers to slow down, sit with ambiguity and experience language in ways that plumb interior life.

If today’s algorithms reward speed, branding and certainty, poetry rewards reflection. This is the thesis of professor and Atlantic editor Walt Hunter’s illuminating – and quite encouraging – recent article, “Stop Meeting Students Where They Are,” which we recently discussed in detail on my podcast, “Some Things Considered.”

Young Americans may not have given up after all

Younger people are not oblivious about the world’s problems. The young poets I’ve been reading see empathy not as weakness, but as a bold imperative to help make the world a kinder, more just place.

I can hardly think of a better example than 16-year-old poet Dave Thompson’s provocatively titled “What if Jesus Was a Little Brown Boy in the USA”:

But you are here.
A little God walking to school,
still foolish enough
still holy enough
to believe love might mean
what it says.

As a podcaster and professor of storytelling, I can’t count how many times I’ve heard people my age or older lament that today’s generation doesn’t read or doesn’t care. This issue comes up at almost every panel discussion I’ve recently participated in.

I think these kinds of assertions about young people are both simplistic and unhelpful. In some ways, while mental health is a real concern for young people, they are doing better than their predecessors in other ways. Youth arrest rates have been declining since the 1990s in the U.S., for example, and American high school students are more likely than ever to graduate.

I think we should pay attention to some of the messages that these young poets are sending. We might even seek to emulate them.

Sean points out in this essay that: “The young poets I’ve been reading see empathy not as weakness, but as a bold imperative to help make the world a kinder, more just place.”

And then there is the poetry from Dave Thompson, presented above. Dave is sixteen, sixty-five years younger than me, but showing that age isn’t an issue. In his poem he writes: “… to believe love might mean what it says.”

Beautiful!

Better understanding of Dopamine

I had little idea about dopamine, and I suspect that I’m not the only person.

Luckily, there are a number of medical websites that describe the role of dopamine in some details.

First, a small part of an AI report based on information from HealthDirect

Dopamine is a critical neurotransmitter and hormone that acts as the brain’s chemical messenger, playing a central role in motivation, reward-motivated behavior, pleasure, and motor control.

Second, part of an explanation from Cleveland Clinic.

Dopamine is a neurotransmitter made in your brain. It plays a role as a “reward center” and in many body functions, including memory, movement, motivation, mood, attention and more. High or low dopamine levels are associated with diseases including Parkinson’s disease, restless legs syndrome and attention deficit hyperactivity disorder (ADHD).

Third, Psychology Today reports.

Dopamine is known as the feel-good neurotransmitter—a chemical that ferries information between neurons. The brain releases it when we eat food that we crave or while we have sex, contributing to feelings of pleasure and satisfaction as part of the reward system. This important neurochemical boosts mood, motivation, and attention, and helps regulate movement, learning, and emotional responses.

How does dopamine make you feel? 

Dopamine causes you to want, desire, seek out, and search. It increases your general level of arousal and your goal-directed behavior. Dopamine makes you curious about ideas and fuels your search for information. Dopamine creates reward-seeking loops in the sense that people will repeat pleasurable behavior, from checking Instagram to taking drugs.

Swedish pharmacologist and neuroscientist Arvid Carlsson won the Nobel prize in 2000 for his research on dopamine, showing its importance in brain function. He helped show that the neurotransmitter is heavily involved in the motor system. When the brain fails to produce enough dopamine, it can result in Parkinson’s disease. The primary treatment for Parkinson’s disease is a drug called L-dopa, which spurs the production of dopamine.

Dopamine has also been implicated in schizophrenia and ADHD; the brain systems underlying these conditions (as well as substance abuse disorder) are complex. The activity of the dopamine system depends on the state of one’s dopamine receptors, and in people with these conditions, the chemical interacts with other factors in ways that have yet to be explained.

How does dopamine function in the brain? 

It is no exaggeration to say that dopamine makes us human. Beginning in infant development, dopamine levels are critical, and mental disabilities can arise if dopamine is not present in sufficient quantities. Dopamine is implicated in genetic conditions like congenital hypothyroidism. Dopamine deficiency is also implicated in other conditions such as Alzheimer’s, depressive disorders, binge-eating, addiction, and gambling.

ooOOoo

My darling Jean takes Carbidopa-Levodopa four times a day and has been doing so for many years.

As one can see from the above extracts, dopamine is incredibly important for the human brain.

Dopamine makes us human!

Where nature draws the map – here are 5 ways to look at the US, without state boundaries

State boundaries can be iconic. Many were drawn by human hands, but some of the most recognizable contours were shaped by nature: the boot of southeastern Louisiana, carved by the Mississippi River, or the ocean waves sculpting the hook of Cape Cod in Massachusetts.

For a moment, imagine that there are no state lines. View the United States through its natural contours. As curators at the Smithsonian’s National Museum of Natural History, we often look at our nation this way, drawing different kinds of maps that trace mountains, watersheds, animal migrations, biomes, ancient seas and so much more.

These kinds of maps show us how connected we all are by nature, since it transcends state boundaries. That idea is central to our new exhibition, “From These Lands: Sharing Our Natural and Cultural Heritage,” now open at our museum to mark the 250th anniversary of the United States. We are co-curators of the show, part of a team of exhibit designers and developers who created the exhibition.

“From These Lands” uses items from the museum’s collections to explore these patterns and ideas, offering a way to see the country’s natural and cultural heritage beyond state lines.

One country, many pine cones

Pine cones can be easy to overlook.

When you’re out for a walk in the woods, you see the forest, maybe even the trees, but not always the cones at your feet. For many people, a pine cone is just a pine cone. But when you look closely, subtle differences in the styles of cones carry clues about the trees that produced them and the places where those trees live.

Several pine cones of different sizes and shapes arranged on a white background, showing variation among pine species.

There are 43 pine species native to the United States, making up nearly a third of the world’s pine tree diversity. Together, they stretch across surprisingly different combinations of climate, terrain, plants and animals, the regions scientists call biomes. Something as simple as the pine cone can let you hold that concept in your hand: soils, fire, rain, birds and rodents all helped shape the tree that made it.

For example, cones from the sand pine can shield seeds for years, only to release them as the heat from low-intensity fires melts their resin and opens their scales. These scrubby and fire-shaped landscapes are one part of the larger temperate evergreen forests that spread through the southeastern U.S.

On the other side of the country, the Coulter pine produces cones that can be more than a foot-and-half long (50 centimeters) and weigh up to 8 pounds (3.5 kilograms). This large cone size helps its seeds to survive fires, allowing small birds and mammals to then disperse them into new areas in the Mediterranean Scrub of Southern California.

A pine cone comes from one tree in one place, but its form reflects a wide set of environmental conditions. Pine cones provide an interesting way to view the different biomes found in the United States and its territories.

An ancient ocean in the middle of the country

The land under your feet can be millions of years old, and it has not always been dry ground.

During the late Mesozoic Era – the time interval made famous by the dinosaurs – a warm, shallow inland sea covered states from North Dakota to Texas. This Western Interior Seaway laid down many of the rocks and sediments that you can see today throughout the Great Plains and Badlands. The sea was also full of life, and the rocks it left behind are full of fossils.

There were familiar characters living on this ancient seafloor: clams, snails and sea stars. But swimming in the waters above were the now-extinct animals called ammonites.

These coiled, shelled relatives of squid and octopuses were abundant predators, hunting in the same waters as fish, turtles, sharks and extinct marine reptiles called plesiosaurs. Ammonites used the chambers in their shells to control buoyancy, much like the modern nautilus.

Ammonite fossils demonstrate that much of the central U.S. was an ancient ocean. They also remind us that the landscapes we know today are just the latest version of those reshaped over and over by the slow work of geologic time.

Unlikely pairing: Shorebirds and horseshoe crabs

Animals move. Some travel only short distances with the seasons, but others travel thousands of miles, crossing not only state lines, but countries, oceans and hemispheres. Animal migration routes might look chaotic on a map, but birds, whales, turtles and more forge these paths for specific reasons.

Timing is a key component of migration. Thanks to a critical refueling stop in Delaware Bay, the ruddy turnstone shorebird manages to migrate thousands of miles each year to its breeding grounds in the high Arctic. These East Coast migrants time their layover with the migration of horseshoe crabs, which come ashore to lay millions of nutrient-packed eggs on beaches. The turnstones gorge themselves on those eggs before continuing their journey north.

It is a strange and wonderful handoff between an ancient marine animal hauling itself out of the ocean and a weary shorebird bound for the Arctic. A single bay brings them together, illustrating how the many migration routes through these lands can hinge on key moments and places.

Salamander country

Topography is more than scenic landscapes. Everything from the flat coastal plains to the ridges, valleys and stream-cut mountainsides helps shape where animals can live and how biodiversity accumulates.

The rugged terrain of the Appalachian Mountains creates cool, wet forests, shaded hollows, caves, ponds and streams. These habitats can differ from each other in elevation, temperature, moisture and water flow – and salamanders take note. More salamander species live in the Appalachian Mountains than anywhere else in the world. It can feel as though every other rock you turn over hides yet another species.

The trio of Plethodon salamanders, the southern gray-cheeked, red-cheeked and red-legged salamanders, were once thought to be regional variations of the same species. But these salamanders live at varying elevations in different mountain ranges, and genetic sequencing confirmed that each was, in fact, its own species. Topography and shifting climates had broken up these populations into different habitats, allowing each to evolve into distinct species.

Following the American shad

Chesapeake Bay is the largest estuary in the U.S., fed by a watershed connecting rivers and drainage basins that reach into six states and the District of Columbia. It’s home to more than 3,600 species, including oysters and blue crabs. But one fish in particular has become strongly intertwined with the lives and cultures of many people around the bay.

The American shad spends much of its adult life in the Atlantic Ocean but returns to the freshwater rivers in the upper reaches of the Chesapeake Bay to spawn. For more than 12,000 years, this herring’s spring migration has been part of Pamunkey Indian Tribe diet and culture.

From 1918 to 2019, to mitigate declining populations of herring, the tribe ran a hatchery to “give back to the river.” The Pamunkey Tribe’s fishing rights date back to their 1677 treaty with the British Crown. Today, only the Pamunkey and citizens of other tribes in Virginia can legally fish for shad in this region.

A single type of fish moving between salt and freshwater, tracing the paths of the watershed, has helped to shape centuries of diet, law, culture and stewardship, highlighting the many connections between nature and culture.

Different ways to map the country

Pine cones, ammonites, shorebirds, salamanders and shad tell more than individual stories about particular places. Together, they point to older and larger patterns: varied forests, vanished seas, seasonal migrations, mountain habitats and rivers that harbor a fantastic diversity of life.

State lines are one way to picture the U.S., but natural history provides another – one that shows the ancient and living connections running across the landscape.

Not having a father

Prompted to write this after reading an article in The Conversation.

I turned 12 in November, 1956. My father died on December, 20th, 1956.

My mother eventually remarried and my step-father quickly became a wonderful Dad to me. But the shock of my father’s death never left me, and the fact that I am writing this some 70 years later shows that the episode is still with me, albeit in a much reduced way.

Thus this article in The Conversation hits the mark.

What we misunderstand about absent fathers

Dads aren’t always in the picture. Motortion/iStock via Getty Images

Matthew Alemu, University of Michigan; Northeastern University

“What do dads do on Tuesdays?”

This wasn’t a rhetorical question when I posed it to my wife as our daughter’s birth approached. Before my daughter was born, I had seen my father just once in the past 27 years. That’s over 1,400 Tuesdays. In fact, as a kid I hardly saw fathering any day of the week, save for on TV sitcoms; absent dads were prevalent within my family and among my peers.

My daughter was born on a Saturday. My first Tuesday as a father came and went in a blur of exhaustion. I’d always loved playing and working with kids. I felt generally competent in what to do with my newborn daughter. Yet as I held her, insecurity from my father’s absence kept me questioning: Will I be better than my absent father?

Absence assumes different forms

Years before my daughter’s birth, I was a first-year Ph.D. student intending to study Black men and how their memories of childhood affected them as adults.

My pivot toward focusing on fatherhood began while I was conducting interviews for a larger study on men of all races and unemployment. After completing these interviews, I was surprised to see that 85% of my respondents grew up with absent fathers. The nature of the absences – how they occurred and how they felt – struck me as a more compelling area of study.

Historically, scholars and policymakers looked at whether fathers lived with their kids as the sole criterion when designating them as “present” or “absent.” Yet, my respondents’ stories revealed distinctions that “nonresident” alone did not capture. Specifically, my analysis identified four unique patterns of absence: “consistent,” “inconsistent,” “extended” and “absolute.”

Consistent absence includes regular interactions, like every Tuesday after school or every weekend.

Inconsistent absence involves irregular and unpredictable interactions – a dad who promises to show up on Tuesday but doesn’t appear until Friday, or disappears for weeks at a time.

Extended absence occurs when years pass between interactions: meeting your father for the first time at 9 years old, and then having no interaction with him until he shows up at your high school graduation, for instance.

Finally, absolute absence means interactions never occurred or they can no longer occur, such as a father who died or disappeared, with his whereabouts unknown. Some people in this category didn’t even know their fathers’ names.

These categories complicate what can otherwise be oversimplified.

For example, the fathers of Presidents Bill Clinton and Barack Obama were both absent, but in distinctly different ways.

Clinton’s biological father died in a car accident before he was born – an absolute absence. Obama’s father left the family when Barack was 2 years old and reappeared only once, years later – a relationship characterized by extended absence.

In contrast, other famous people saw their absent fathers more regularly.

The parents of the rapper Ye, formerly known as Kanye West, divorced when he was 3 years old, but he grew up spending summers with his father, putting the absence in the “consistent” category. Similarly, Maroon 5 singer Adam Levine regularly saw his dad on weekends after his parents divorced, which I also classify as a consistent form of absence.

Better than my father, or better than his absence?

Ironically, I became a father as I began my dissertation research on absent fathers. Using the four categories of paternal absence I developed, my dissertation examined how men’s experiences with absence shaped their own aspirations for fatherhood and romantic relationships.

I wanted to showcase the complexity and range of experiences of growing up with an absent father, while also exposing the disparity in how people remembered their absent fathers. Specifically, some people knew their fathers, while others knew only that their father was absent. This memory gap makes it harder for some new dads to envision what it means to be better than their own fathers.

Like me, the men I interviewed for my research relayed anxieties about navigating fatherhood. Like me, they wanted to be better than their fathers.

But we all differed in how prepared we felt for the task. Some had vivid memories to guide them: One respondent, who experienced inconsistent absence, hated that his father never showed curiosity in getting to know him. So when he became a parent, he made sure to ask his daughter questions so she would know he cared about her life.

Yet those with little to no memories of their father may aspire to be, as another respondent put it, “a father like my mother.”

Doing this work, I’ve been able to reimagine my own experience with absence.

I used to assume that the pattern of absence I experienced with my own dad reflected a standard. My parents divorced when I was 3 years old. I saw my father regularly until moving away at 6 – a form of consistent absence. But the rest of my childhood passed without seeing my father, shifting me to extended absence. I used to wrongly dismiss less extreme patterns of absence, such as seeing one’s father weekly or monthly, as “not absence.”

My unique experience of absence has also distinctly shaped how I remember my father. My memories mainly come from 6 years old and earlier. Many are unfavorable, like his smoking in the car, knowing I had asthma. Some fond ones exist, like the two of us walking on the beach or feeding ducks at a local pond.

Still, what I recall most is my fear of my father. The origins of this fear escape me. I’ve been told he abused my mother, but I don’t remember witnessing it.

These scant memories presented a paradox as I entered fatherhood: I didn’t want to be feared like my father, but I didn’t know exactly what made me afraid of my father. This uncertainty loomed throughout my early years of parenting: When my daughter cried in my arms or preferred my wife over me, was it simply a sign of normal fussiness? Or had I unknowingly become a scary figure, like my father?

From abandoned son to present father

I last met my father 20 years ago. I was full of hate when that meeting began, but this hatred soon dissipated. First, I realized I wasn’t angry at my father, because I barely knew my father. I was angry at his absence. Second, I learned that his father was absent, too.

They say “hurt people hurt people.” Before my dad was an absent father, he was missing his dad, too. This doesn’t excuse his absence or his treatment of my mother. But it did make it harder to hate someone who was probably hurting like me.

As I continue to explore the impact of absent fathers as an academic, I continue to reconcile my transition from abandoned son to a present father. Lacking inspiration or guidance from my own father, I’m practicing fatherhood on my terms.

For me, that’s meant building traditions. From the outset, we’ve created routines around music, dancing, bath time, reading and talking about “big emotions.” Our most meaningful tradition has been our weekly daddy-daughter breakfast, which I started when she was 18 months old. She’s now 8.

Sometimes we go on Tuesdays. But any day of the week is fair game.

Now Matthew Alema was much more furtunate than me. At least he saw his father from time to time.

I often reflect how my life would have been different had my father lived for much longer, say until he was in his 70’s or 80’s. There’s no question it would have been significant. I would have had a profession, possibly in the designing of buildings. I would have gone to university, And so on …

I have a son and a daughter, both in their 50’s, and a grandson by my daughter and her husband. I am so grateful to be able to speak to them on a regular basis. They all live in England.

Fabulous colours at dawn.

Last Thursday, the 18th, I happened to glance out of the kitchen window. It was about 0445 PST and the colours of the sky were magnificent.

I immediatly grabbed my camera and went onto the deck, looking towards Mount Sexton.

And we should not forget that today is the Summer Solstice.

The June solstice arrives at 8:25 UTC (3:25 a.m. CDT) on June 21, 2026. For the Northern Hemisphere, it’s the longest day and shortest night. For the Southern Hemisphere, it’s the shortest day and longest night. Watch this video with EarthSky’s Deborah Byrd to learn the top 3 sky sights on this June solstice 2026. And what does “sun stands still” really mean? Plus, EarthSky’s Will Triggs joins to tell us about visiting Stonehenge on the solstice!

The reason behind the human ‘week’.

A fascinating history of our week.

Why are there seven days in a week?

The Conversation published a post on this subject back in 2020 under their Curious Kids title. That may have been the reason I did not republish it.

But on June 5th this year, Kelly Kizer Whitt published on EarthSky an article explaining how the ‘week’ came about.

However, I am going to republish the item, as posted by The Conversation.

Why are there seven days in a week? – Henry E., age 8, Somerville, Massachusetts


Waiting for the weekend can often seem unbearable, a whole six days between Saturdays. Having seven days in a week has been the case for a very long time, and so people don’t often stop to ask why.

Most of our time reckoning is due to the movements of the planets, Moon and stars. Our day is equal to one full rotation of the Earth around its axis. Our year is a revolution of the Earth around the Sun, which takes 365 and ¼ days, which is why we add an extra day in February every four years, for a leap year.

But the week and the month are a bit trickier. The phases of the Moon do not exactly coincide with the solar calendar. The Moon cycle is 27 days and seven hours long, and there are 13 phases of the Moon in each solar year.

Some of the earliest civilizations observed the cosmos and recorded the movements of planets, the Sun and Moon. The Babylonians, who lived in modern-day Iraq, were astute observers and interpreters of the heavens, and it is largely thanks to them that our weeks are seven days long.

The reason they adopted the number seven was that they observed seven celestial bodies – the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn. So, that number held particular significance to them.

Other civilizations chose other numbers – like the Egyptians, whose week was 10 days long; or the Romans, whose week lasted eight.

The Babylonians divided their lunar months into seven-day weeks, with the final day of the week holding particular religious significance. The 28-day month, or a complete cycle of the Moon, is a bit too large a period of time to manage effectively, and so the Babylonians divided their months into four equal parts of seven.

The number seven is not especially well-suited to coincide with the solar year, or even the months, so it did create a few inconsistencies.

However, the Babylonians were such a dominant culture in the Near East, especially in the sixth and seventh centuries B.C., that this, and many of their other notions of time – such as a 60-minute hour – persisted.

The seven-day week spread throughout the Near East. It was adopted by the Jews, who had been captives of the Babylonians at the height of that civilization’s power. Other cultures in the surrounding areas got on board with the seven-day week, including the Persian empire and the Greeks.

Centuries later, when Alexander the Great began to spread Greek culture throughout the Near East as far as India, the concept of the seven-day week spread as well. Scholars think that perhaps India later introduced the seven-day week to China.

Finally, once the Romans began to conquer the territory influenced by Alexander the Great, they too eventually shifted to the seven-day week. It was Emperor Constantine who decreed that the seven-day week was the official Roman week and made Sunday a public holiday in A.D. 321.

The weekend was not adopted until modern times in the 20th century. Although there have been some recent attempts to change the seven-day week, it has been around for so long that it seems like it is here to stay.

So there we are, the ancient history of the week. Including the fact that the weekend was not adopted until the 20th century. In the 1940’s to be precise.
