Why Do We Have Crooked Teeth When Our Ancestors Didn’t?

Evidence shows that people in ancient times typically had straight teeth set well into strong jaws, with even wisdom teeth fitting properly.
So, what went wrong? Did evolution do us a disservice?
Some information to chew on
Transition from hard-to-chew diets to processed, refined foods over millennia has reduced jaw size while tooth size stayed constant. Smaller jaws lead to tooth crowding, crookedness, and impacted wisdom teeth, requiring braces or extractions in modern times.
However, all is not lost!
Studies on non-human animals show softer diets reduce jaw and facial growth, causing dental crowding. In other words: dental crowding is primarily attributed to dietary and lifestyle changes, though genetics may play a role.
And notably, when it comes to humans, populations with less processed diets experience fewer dental problems, suggesting lifestyle modifications could help prevent tooth crowding.
And no, it is not too late. Remember, you are rebuilding your body all the time, including your bones!

Chatter – by Dr. Ethan Kross
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
This book is about much more than just one’s internal monologue. It does tackle that, but also the many non-verbal rabbit-holes that our brains can easily disappear into.
The author is an experimental psychologist, and brings his professional knowledge and experience to bear on this problem—citing many studies, including his own studies from his own lab, in which he undertook to answer precisely the implicit questions of “How can I…” in terms of tackling these matters, from root anxiety (for example) to end-state executive dysfunction (for example).
The writing style isn’t dense science though, and is very approachable for all.
The greatest value in this book lies in its prescriptive element, that is to say, its advice, especially in the category of evidence-based things we can do to improve matters for ourselves; beyond generic things like “mindfulness-based stress reduction” to much more specific things like “observe yourself in the 3rd person for a moment” and “take a break to imagine looking back on this later” and “interrupt yourself with a brief manual task”. With these sorts of interventions and more, we can shift the voice in our head from critic to coach.
Bottom line: if you would like your brain to let you get on with the things you actually want to do instead of constantly sidetracking you, this is the book for you.

Good to Go – by Christie Aschwanden

Many of us may more often need to recover from a day of moving furniture than running a marathon, but the science of recovery can still teach us a lot. The author, herself an endurance athlete and much-decorated science journalist, sets out to do just that.
She explores a lot of recovery methods, and examines whether the science actually backs them up, and if so, to what degree. She also, in true science journalism style, talks to a lot of professionals ranging from fellow athletes to fellow scientists, to get their input too—she is nothing if not thorough, and this is certainly not a book of one person’s opinion with something to sell.
Indeed, on the contrary, her findings show that some of the best recovery methods are the cheapest, or even free. She also looks at the psychological aspect though, and why many people are likely to continue with things that objectively do not work better than placebo.
The style is very easy-reading jargon-free pop-science, while nevertheless being backed up with hundreds of studies cited in the bibliography—a perfect balance of readability and reliability.
Bottom line: for those who wish to be better informed about how to recover quickly and easily, this book is a treasure trove of information well-presented.

The End of Alzheimer’s – by Dr. Dale Bredesen
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
This one didn’t use the “The New Science Of…” subtitle that many books do, and this one actually is a “new science of”!
Which is exciting, and/but comes with the caveat that the overall protocol itself is still undergoing testing, but the results so far are promising. The constituent parts of the protocol are for the most already well-established, but have not previously been put together in this way.
Dr. Bredesen argues that Alzheimer’s Disease is not one condition but three (medical consensus agrees at least that it is a collection of conditions, but different schools of thought slice them differently), and outlines 36 metabolic factors that are implicated, and the good news is, most of them are within our control.
Since there’s a lot to put together, he also offers many workarounds and “crutches”, making for very practical advice.
The style of the book is on the hard end of pop-science, that is to say while the feel and tone is very pop-sciencey, there are nevertheless a lot of words that you might know but your spellchecker probably wouldn’t. He does explain everything along the way, but this does mean that if you’re not already well-versed, you can’t just dip in to a later point without reading the earlier parts.
Bottom line: even if you only implement half the advice in this book, you’ll be doing your long-term cognitive health a huge favor.

How To Reduce Knee Pain After Sitting
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Sitting is bad for the health, and doubly so if you have arthritis, as a lack of regular movement can cause joints to “seize up”. So, what to do about it if you have to sit for an extended time?
Dr. Alyssa Kuhn, arthritis specialist, explains:
Movement remains key
The trick is to continue periodically moving, notwithstanding that you may need to remain seated. So…
- Heel slides
- Straighten and bend your leg by sliding or lifting your heel.
- Promotes blood flow and reduces fluid buildup in the knee.
- Helps lubricate the joint, making standing up easier.
- Heel lifts
- Lift your heels up and down while keeping feet on the ground.
- This one’s ideal for tight spaces, such as when riding in a car or airplane.
- Improves blood circulation and can reduce ankle swelling and leg heaviness.
Do 20–30 repetitions every now and again, to keep your joints moving.
Note: if you are a wheelchair user whose legs lack the strength and/or motor function to do this, in this case it’s the movement of the leg that counts, not where that movement originated from. So, if you use one hand to lift your leg slightly and the other to push it like a swing, that will also be sufficient to give the joint the periodic movement it needs.

Older Men’s Connections Often Wither When They’re on Their Own
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
At age 66, South Carolina physician Paul Rousseau decided to retire after tending for decades to the suffering of people who were seriously ill or dying. It was a difficult and emotionally fraught transition.
“I didn’t know what I was going to do, where I was going to go,” he told me, describing a period of crisis that began in 2017.
Seeking a change of venue, Rousseau moved to the mountains of North Carolina, the start of an extended period of wandering. Soon, a sense of emptiness enveloped him. He had no friends or hobbies — his work as a doctor had been all-consuming. Former colleagues didn’t get in touch, nor did he reach out.
His wife had passed away after a painful illness a decade earlier. Rousseau was estranged from one adult daughter and in only occasional contact with another. His isolation mounted as his three dogs, his most reliable companions, died.
Rousseau was completely alone — without friends, family, or a professional identity — and overcome by a sense of loss.
“I was a somewhat distinguished physician with a 60-page resume,” Rousseau, now 73, wrote in the Journal of the American Geriatrics Society in May. “Now, I’m ‘no one,’ a retired, forgotten old man who dithers away the days.”
In some ways, older men living alone are disadvantaged compared with older women in similar circumstances. Research shows that men tend to have fewer friends than women and be less inclined to make new friends. Often, they’re reluctant to ask for help.
“Men have a harder time being connected and reaching out,” said Robert Waldinger, a psychiatrist who directs the Harvard Study of Adult Development, which has traced the arc of hundreds of men’s lives over a span of more than eight decades. The men in the study who fared the worst, Waldinger said, “didn’t have friendships and things they were interested in — and couldn’t find them.” He recommends that men invest in their “social fitness” in addition to their physical fitness to ensure they have satisfying social interactions.
Slightly more than 1 in every 5 men ages 65 to 74 live alone, according to 2022 Census Bureau data. That rises to nearly 1 in 4 for those 75 or older. Nearly 40% of these men are divorced, 31% are widowed, and 21% never married.
That’s a significant change from 2000, when only 1 in 6 older men lived by themselves. Longer life spans for men and rising divorce rates are contributing to the trend. It’s difficult to find information about this group — which is dwarfed by the number of women who live alone — because it hasn’t been studied in depth. But psychologists and psychiatrists say these older men can be quite vulnerable.
When men are widowed, their health and well-being tend to decline more than women’s.
“Older men have a tendency to ruminate, to get into our heads with worries and fears and to feel more lonely and isolated,” said Jed Diamond, 80, a therapist and the author of “Surviving Male Menopause” and “The Irritable Male Syndrome.”
Add in the decline of civic institutions where men used to congregate — think of the Elks or the Shriners — and older men’s reduced ability to participate in athletic activities, and the result is a lack of stimulation and the loss of a sense of belonging.
Depression can ensue, fueling excessive alcohol use, accidents, or, in the most extreme cases, suicide. Of all age groups in the United States, men over age 75 have the highest suicide rate, by far.
For this column, I spoke at length to several older men who live alone. All but two (who’d been divorced) were widowed. Their experiences don’t represent all men who live alone. But still, they’re revealing.
The first person I called was Art Koff, 88, of Chicago, a longtime marketing executive I’d known for several years. When I reached out in January, I learned that Koff’s wife, Norma, had died the year before, leaving him hobbled by grief. Uninterested in eating and beset by unremitting loneliness, Koff lost 45 pounds.
“I’ve had a long and wonderful life, and I have lots of family and lots of friends who are terrific,” Koff told me. But now, he said, “nothing is of interest to me any longer.”
“I’m not happy living this life,” he said.
Nine days later, I learned that Koff had died. His nephew, Alexander Koff, said he had passed out and was gone within a day. The death certificate cited “end stage protein calorie malnutrition” as the cause.
The transition from being coupled to being single can be profoundly disorienting for older men. Lodovico Balducci, 80, was married to his wife, Claudia, for 52 years before she died in October 2023. Balducci, a renowned physician known as the “patriarch of geriatric oncology,” wrote about his emotional reaction in the Journal of the American Geriatrics Society, likening Claudia’s death to an “amputation.”
“I find myself talking to her all the time, most of the time in my head,” Balducci told me in a phone conversation. When I asked him whom he confides in, he admitted, “Maybe I don’t have any close friends.”
Disoriented and disorganized since Claudia died, he said his “anxiety has exploded.”
We spoke in late February. Two weeks later, Balducci moved from Tampa to New Orleans, to be near his son and daughter-in-law and their two teenagers.
“I am planning to help as much as possible with my grandchildren,” he said. “Life has to go on.”
Verne Ostrander, a carpenter in the small town of Willits, California, about 140 miles north of San Francisco, was reflective when I spoke with him, also in late February. His second wife, Cindy Morninglight, died four years ago after a long battle with cancer.
“Here I am, almost 80 years old — alone,” Ostrander said. “Who would have guessed?”
When Ostrander isn’t painting watercolors, composing music, or playing guitar, “I fall into this lonely state, and I cry quite a bit,” he told me. “I don’t ignore those feelings. I let myself feel them. It’s like therapy.”
Ostrander has lived in Willits for nearly 50 years and belongs to a men’s group and a couples’ group that’s been meeting for 20 years. He’s in remarkably good health and in close touch with his three adult children, who live within easy driving distance.
“The hard part of living alone is missing Cindy,” he told me. “The good part is the freedom to do whatever I want. My goal is to live another 20 to 30 years and become a better artist and get to know my kids when they get older.”
The Rev. Johnny Walker, 76, lives in a low-income apartment building in a financially challenged neighborhood on Chicago’s West Side. Twice divorced, he’s been on his own for five years. He, too, has close family connections. At least one of his several children and grandchildren checks in on him every day.
Walker says he had a life-changing religious conversion in 1993. Since then, he has depended on his faith and his church for a sense of meaning and community.
“It’s not hard being alone,” Walker said when I asked whether he was lonely. “I accept Christ in my life, and he said that he would never leave us or forsake us. When I wake up in the morning, that’s a new blessing. I just thank God that he has brought me this far.”
Waldinger recommended that men “make an effort every day to be in touch with people. Find what you love — golf, gardening, birdwatching, pickleball, working on a political campaign — and pursue it,” he said. “Put yourself in a situation where you’re going to see the same people over and over again. Because that’s the most natural way conversations get struck up and friendships start to develop.”
Rousseau, the retired South Carolina doctor, said he doesn’t think about the future much. After feeling lost for several years, he moved across the country to Jackson, Wyoming, in the summer of 2023. He embraced solitude, choosing a remarkably isolated spot to live — a 150-square-foot cabin with no running water and no bathroom, surrounded by 25,000 undeveloped acres of public and privately owned land.
“Yes, I’m still lonely, but the nature and the beauty here totally changed me and focused me on what’s really important,” he told me, describing a feeling of redemption in his solitude.
Rousseau realizes that the death of his parents and a very close friend in his childhood left him with a sense of loss that he kept at bay for most of his life. Now, he said, rather than denying his vulnerability, he’s trying to live with it. “There’s only so long you can put off dealing with all the things you’re trying to escape from.”
It’s not the life he envisioned, but it’s one that fits him, Rousseau said. He stays busy with volunteer activities — cleaning tanks and running tours at Jackson’s fish hatchery, serving as a part-time park ranger, and maintaining trails in nearby national forests. Those activities put him in touch with other people, mostly strangers, only intermittently.
What will happen to him when this way of living is no longer possible?
“I wish I had an answer, but I don’t,” Rousseau said. “I don’t see my daughters taking care of me. As far as someone else, I don’t think there’s anyone else who’s going to help me.”

Fennel vs Onion – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing fennel to onion, we picked the fennel.
Why?
First note, in case you didn’t see the picture: we are talking about white onions here (also called brown onions, by virtue of their attire).
Looking at the macros, fennel has nearly 2x the fiber and a little more protein, while onion has more carbs. An easy win in this category for the fennel.
In the category of vitamins, fennel has more of vitamins A, B2, B3, B5, B9, C, E, K, and choline (most of them by generous margins and some by especially large margins, we are talking, for example, 480x the vitamin A, 29x the vitamin E, and 157x the vitamin K), while onions have more of vitmains B1 and B6. Another clear win for fennel.
When it comes to minerals, fennel has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while onion is not higher in any minerals. No prizes for guessing: fennel wins this category too.
You may be curious as to how they add up on the polyphenol front, and the answer is, they don’t, much. Wonderful as these two vegetables are, an abundance of polyphenols is not amongst their strengths; fennel has some lignans and onion has some flavonols, but we’re talking tiny numbers here (in contrast, red onion would have aced it with 120mg/100g quercetin, amongst others, but red onion wasn’t on trial today).
Adding up the sections makes a clear win for fennel today.
