Keep Your Wits About You – by Dr. Vonetta Dotson
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.
Dr. Dotson sets out to provide the reader with the tools to maintain good brain health at any age, though she does assume the reader to be in midlife or older.
She talks us through the most important kinds of physical activity, mental activity, and social activity, as well as a good grounding in brain-healthy nutrition, and how to beat the often catch-22 situation of poor sleep.
If you are the sort of person who likes refreshers on what you have just read, you’ll enjoy that the final two chapters repeat the information from chapters 2–6. If not, then well, if you skip the final 2 chapters the book will be 25% shorter without loss of content.
The style is enthusiastic; when it comes to her passion for the brain, Dr. Dotson both tells and shows, in abundance. While some authors may take care to break down the information in a way that can be understood from skimming alone, Dr. Dotson assumes that the reader’s interest will match hers, and thus will not mind a lot of lengthy prose with in-line citations. So, provided that’s the way you like to read, it’ll suit you too.
Bottom line: if you are looking for a book on maintaining optimal brain health that covers the basics without adding advice that is out of the norm, then this is a fine option for that!

Alzheimer’s Causative Factors To Avoid
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.
The Best Brains Bar Nun?
This is Dr. David Snowdon. He’s an epidemiologist, and one of the world’s foremost experts on Alzheimer’s disease. He was also, most famously, the lead researcher of what has become known as “The Nun Study”.
We recently reviewed his book about this study:
…which we definitely encourage you to check out, but we’ll do our best to summarize its key points today!
Reassurance up-front: no, you don’t have to become a nun
The Nun Study
In 1991, a large number (678) of nuns were recruited for what was to be (and until now, remains) the largest study of its kind into the impact of a wide variety of factors on aging, and in particular, Alzheimer’s disease.
Why it was so important: because the nuns were all from the same Order, had the same occupation (it’s a teaching Order), with very similar lifestyles, schedules, socioeconomic status, general background, access to healthcare, similar diets, same relationship status (celibate), same sex (female), and many other factors also similar, this meant that most of the confounding variables that confound other studies were already controlled-for here.
Enrollment in the study also required consenting to donating one’s brain for study post-mortem—and of those who have since died, indeed 98% of them have been donated (the other 2%, we presume, may have run into technical administrative issues with the donation process, due to the circumstances of death and/or delays in processing the donation).
How the study was undertaken
We don’t have enough space to describe the entire methodology here, but the gist of it is:
- Genetic testing for relevant genetic factors
- Data gathered about lives so far, including not just medical records but also autobiographies that the nuns wrote when they took their vows (at ages 19–21)
- Extensive ongoing personal interviews about habits, life choices, and attitudes
- Yearly evaluations including memory tests and physical function tests
- Brain donation upon death
What they found
Technically, The Nun Study is still ongoing. Of the original 678 nuns (aged 75–106), three are still alive (based on the latest report, at least).
However, lots of results have already been gained, including…
Genes
A year into the study, in 1992, the “apolipoprotein E” (APOE) gene was established as a likely causative factor in Alzheimer’s disease. This is probably not new to our readers in 2024, but there are interesting things being learned even now, for example:
The Alzheimer’s Gene That Varies By Race & Sex
…but watch out! Because also:
Alzheimer’s Sex Differences May Not Be What They Appear
Words
Based on the autobiographies written by the nuns in their youth upon taking their vows, there were two factors that were later correlated with not getting dementia:
- Longer sentences
- Positive outlook
- “Idea density”
That latter item means the relative linguistic density of ideas and complexity thereof, and the fluency and vivacity with which they were expressed (this was not a wishy-washy assessment; there was a hard-science analysis to determine numbers).

…for specific, evidence-based ways to tweak your reading to fight cognitive decline.
Food
While the dietary habits of the nuns were fairly homogenous, those who favored eating more and cooked greens, beans, and tomatoes, lived longer and with healthier brains.

Other aspects of brain health & mental health
The study also found that nuns who avoided stroke and depression, were also less likely to get dementia.

- Depression, And The Mental Health First-Aid That You’ll Hopefully Never Need
- Behavioral Activation Against Depression & Anxiety
Community & Faith
Obviously, in this matter the nuns were quite a homogenous group, scoring heavily in community and faith. What’s relevant here is the difference between the nuns, and other epidemiological studies in other groups (invariably not scoring so highly).
Community & faith are considered, separately and together, to be protective factors against dementia.
Faith may be something that “you have it or you don’t” (we’re a health science newsletter, not a theological publication, but for the interested, philosopher John Stuart Mill’s 1859 essay “On Liberty“ makes a good argument for it not being something one can choose, prompting him to argue for religious tolerance, on the grounds that religious coercion is a futile effort precisely because a person cannot choose to dis/believe something)
…but community can definitely be chosen, nurtured, and grown. We’ve written about this a bit before:

Sizing Aside: Are You Wearing The Right Bra For Your Breast Shape?
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.
It’s well-known that most women wear incorrectly-fitting bras. Even with careful measurements, buying “off-the-rack” can be a challenge, because the sizing system only takes two measurements, when there are actually many more things to consider. Today’s video demystifies a lot of what else is going on!
For example…
Some of the different breast shapes/arrangements to consider:
- Wide-set breasts: likely to find there’s a bit of a gap between your breasts and the inside (nearest to your sternum) parts of the cups—while spilling out a little at the outside edges. The solution? Bras that offer side-support, to keep things pointing more forwards. Central-closing bras can also help gather things together, and a balconette bra can redistribute things more evenly. Any of these options will be a lot more comfortable.
- Small breasts: bralettes are your friend, keeping things comfortable while not wearing more bra than necessary to do the job (of course going braless is also an option, but we’re talking bra-fitting here, not bra-flinging-off never to be seen again)
- Deflated breasts: often the case for someone who used to have larger breasts, but they lost size for hormonal reasons rather than for weight loss reasons. This often occurs a little while after childbirth, and also happens a lot in menopause. The bra recommendation for this? A push-up plunge bra with ¾ coverage not only provides cleavage if that’s wanted, but also, will keep things much more snug and thus more evenly-distributed. If ever you’ve found yourself needing to adjust yourself every now and gain while out, this will fix that and keep you comfortable for much longer.

The Hidden Risk of Stretching: Avoiding Hamstring Injuries in Yoga

What is Yoga Butt
Have you ever experienced a mysterious pain while stretching, or perhaps during yoga? You might be dealing with “yoga butt,” a common—although rarely discussed—injury. In the below video, the Lovely Liv from Livinleggings shares her journey of discovering, and overcoming, “yoga butt”.
Dealing With Yoga Butt
Yoga butt, or proximal hamstring tendinopathy, occurs when the hamstrings are overstretched without adequate strengthening. Many yoga poses help stretch the hamstrings, but often don’t focus on strengthening said hamstrings; this imbalance is what can lead to damage over time.
To help prevent Yoga butt, it’s essential to balance stretching with strengthening. You can look into incorporating hamstring-strengthening exercises like Romanian deadlifts, hamstring curls, and modified yoga poses into your routine.
(If you’re new to strengthening exercises, we recommend reading Women’s Strength Training Anatomy Workouts or Strength Training for Seniors).
Watch the full video to learn more and hopefully protect yourself from long-term injuries:

This Is When Your Muscles Are Strongest

Dr. Karyn Esser is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center, and she has insights to share on when it’s best to exercise:
It’s 4–5pm
Surprise, no clickbait or burying the lede!
This goes regardless of age or sex, but as we get older, it’s common for our circadian rhythm to weaken, which may result in a tendency to fluctuate a bit more.
However, since it’s healthy to keep one’s circadian rhythm as stable as reasonably possible, this is a good reason to try to keep our main exercise focused around that time of day, as it provides a sort of “anchor point” for the rest of our day to attach to, so that our body can know what time it is relative to that.
It’s also the most useful time of day to exercise, because most exercises give benefits proportional to progressive overloading, so training at our peak efficiency time will give the most efficient results. So much for those 5am runs!
On which note: while the title says “strongest” and the thumbnail has dumbbells, this does go for all different types of exercises that have been tested.

Shredded Wheat vs Organic Crunch – 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 Shredded Wheat to Organic Crunch, we picked the Shredded Wheat.
Why?
In this battle of the cereals, it comes down to the ingredients:
- The Shredded Wheat cereal has two ingredients: wheat (shredded), and BHT. The latter is a phenolic compound and antioxidant.
- The Organic Crunch cereal has lots of ingredients, of which the first two are wheat flour, and sugar.
This means that, per serving…
- The Shredded Wheat cereal has 7g fiber and 0g sugar
- The Organic Crunch cereal has 3g fiber and 12g sugar
Quite a difference! Sometimes, the “Organic Crunch” of a product comes from crunchy sugar.

Sleep Tracking, For Five Million Nights
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.
5 Sleep Phenotypes, By Actual Science
You probably know people can be broadly divided into “early birds” and “night owls”:
Early Bird Or Night Owl? Genes vs Environment
…and then the term “hummingbird” gets used for a person who flits between the two.
That’s three animals so far. If you read a book we reviewed recently, specifically this one:
The Power of When – by Dr. Michael Breus
…then you may have used the guide within to self-diagnose your circadian rhythm type (chronotype) according to Dr. Breus’s system, which divides people into bears, lions, wolves, and dolphins.
That’s another four animals. If you have a FitBit, it can “diagnose” you with being those and/or a menagerie of others, such as giraffe, hedgehog, parrot, and tortoise:
How Fitbit Developed the Sleep Profile Experience (Part 2 – Sleep Animals)
Five million nights
A team of researchers recently took a step away from this veritable zoo of 11 different animals and counting, and used a sophisticated modelling system to create a spatial-temporal map of people’s sleep habits, and this map created five main “islands” that people’s sleep habits could settle on, or sometimes move from island to island.
Those “five million nights” by the way? It was actually 5,095,798 nights! You might notice that would take from the 2020s to the 15970s to complete, so this was rather a matter of monitoring 33,152 individuals between January and October of the same year. Between them, they got those 5,095,798 nights of sleep (or in some cases, nights of little or no sleep, but still, they were there for the nights).
The five main phenotypes that the researchers found were:
- What we think of as “normal” sleep. In this phenotype, people get about eight hours of uninterrupted sleep for at least six days in a row.
- As above for half the nights, but they only sleep for short periods of time in bouts of less than three hours the other half.
- As per normal sleep, but with one interrupted night per week, consisting of a 5 hour sleep period and then broken sleep for a few more hours.
- As per normal sleep generally, but with occasional nights in which long bouts of sleep are separated by a mid-sleep waking.
- Sleeping for very short periods of time every night. This phenotype was the rarest the researchers found, and represents extremely disrupted sleep.
As you might suspect, phenotype 1 is healthier than phenotype 5. But that’s not hugely informational, as the correlation between getting good sleep and having good health is well-established. So, what did the study teach us?
❝We found that little changes in sleep quality helped us identify health risks. Those little changes wouldn’t show up on an average night, or on a questionnaire, so it really shows how wearables help us detect risks that would otherwise be missed.❞
More specifically,
❝We found that the little differences in how sleep disruptions occur can tell us a lot. Even if these instances are rare, their frequency is also telling. So it’s not just whether you sleep well or not – it’s the patterns of sleep over time where the key info hides❞
…and, which gets to the absolute point,
❝If you imagine there’s a landscape of sleep types, then it’s less about where you tend to live on that landscape, and more about how often you leave that area❞
In other words: if your sleep pattern is not ideal, that’s one thing and it’d probably be good to address it, by improving your sleep. However, if your sleep pattern changes phenotype without an obvious known reason why, this may be considered an alarm bell warning of something else that needs addressing, which may be an underlying illness or condition—meaning it can be worthwhile being a little extra vigilant when it comes to regular health screenings, in case something new has appeared.
