Elderhood – by Dr. Louise Aronson

Where does “middle age” end, and “old age” begin? By the United States’ CDC’s categorization, human life involves:
- 17 stages of childhood, deemed 0–18
- 5 stages of adulthood, deemed 18–60
- 1 stage of elderhood, deemed 60+
Isn’t there something missing here? Do we just fall off some sort of conveyor belt on our sixtieth birthdays, into one big bucket marked “old”?
Yesterday you were 59 and enjoying your middle age; today you have, apparently, the same medical factors and care needs as a 114-year-old.
Dr. Louise Aronson, a geriatrician, notes however that medical science tends to underestimate the differences found in more advanced old age, and underresearch them. That elders consume half of a country’s medicines, but are not required to be included in clinical trials. That side effects not only are often different than for younger adults, but also can cause symptoms that are then dismissed as “Oh she’s just old”.
She explores, mostly through personal career anecdotes, the well-intentioned disregard that is frequently given by the medical profession, and—importantly—how we might overcome that, as individuals and as a society.
Bottom line: if you are over the age of 60, love someone over the age of 60, this is a book for you. Similarly if you and/or they plan to live past the age of 60, this is also a book for you.

The Menopause Brain – by Dr. Lisa Mosconi
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.
With her PhD in neuroscience and nuclear medicine (a branch of radiology, used for certain types of brain scans, amongst other purposes), whereas many authors will mention “brain fog” as a symptom of menopause, Dr. Mosconi can (and will) point to a shadowy patch on a brain scan and say “that’s the brain fog, there”.
And so on for many other symptoms of menopause that are commonly dismissed as “all in your head”, notwithstanding that “in your head” is the worst place for a problem to be. You keep almost your entire self in there!
Dr. Mosconi covers how hormones influence not just our moods in a superficial way, but also change the structure of our brain over time.
Importantly, she also gives an outline of how to stay on the ball; what things to watch out for when your doctor probably won’t, and what things to ask for when your doctor probably won’t suggest them.
Bottom line: if menopause is a thing in your life (or honestly, even if it isn’t but you are running on estrogen rather than testosterone), then this is a book for you.

Algorithms to Live By – by Brian Christian and Tom Griffiths
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.
As humans, we subconsciously use heuristics a lot to make many complex decisions based on “fuzzy logic”. For example:
Do we buy the cheap shoes that may last us a season, or the much more expensive ones that will last us for years? We’ll—without necessarily giving it much conscious thought—quickly weigh up:
- How much do we like each prospective pair of shoes?
- What else might we need to spend money on now/soon?
- How much money do we have right now?
- How much money do we expect to have in the future?
- Considering our lifestyle, how important is it to have good quality shoes?
How well we perform this rapid calculation may vary wildly, depending on many factors ranging from the quality of the advertising to how long ago we last ate.
And if we make the wrong decision, later we may have buyer’s (or non-buyer’s!) remorse. So, how can we do better?
Authors Brain Christian and Tom Griffiths have a manual for us!
This book covers many “kinds” of decision we often have to make in life, and how to optimize those decisions with the power of mathematics and computer science.
The problems (and solutions) run the gamut of…
- Optimal stopping (when to say “alright, that’s good enough”)
- Overcoming cognitive biases
- Scheduling quandaries
- Bayes’ Theorem
- Game Theory
- And when it’s more efficient to just leave things to chance!
…and many more (12 main areas of decision-making are covered).
For all it draws heavily from mathematics and computer science, the writing style is very easy-reading. It’s a “curl up in the armchair and read for pleasure” book, no matter how weighty and practical its content.
Bottom line: if you improve your ability to make the right decisions even marginally, this book will have been worth your while in the long run!

Fast Exercise – by Dr. Michael Mosley & Peta Bee
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.
We’ve written before about the benefits of High-Intensity Interval Training (HIIT), but there’s more to say than we can fit in a short article!
Dr. Michael Mosley, who hates exercise but knows his stuff when it comes to the benefits, teamed up with Peta Bee, who loves exercise and is a science journalist with degrees in sports science and nutrition, to bring us this book.
In it, we learn a lot about:
- the science of HIIT
- what makes it so different from most kinds of exercise
- exactly what benefits one can expect
…in a very detailed clinical fashion (while still remaining very readable).
By “very detailed clinical fashion”, here we mean “one minute of this kind of exercise this many times per week over this period of time will give this many extra healthy life-years”, for example, along with lots of research to back numbers, and explanations of the mechanisms of action (e.g. reducing inflammatory biomarkers of aging, increasing cellular apoptosis, improving cardiometabolic stats for reduced CVD risk, and many things)
There’s also time/space given over to exactly what to do and how to do it, giving enough options to suit personal tastes/circumstances.
Bottom line: if you’d like to make your exercise work a lot harder for you while you spend a lot less time working out, then this book will help you do just that!

Alzheimer’s Causative Factors To Avoid

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:

No Time to Panic – by Matt Gutman
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.
Matt Gutman is not a doctor or a psychologist. He’s a journalist, accustomed to asking questions and then asking more probing questions, unrelenting until he gets the answers he’s looking for.
This book is the result of what happened when he needed to overcome his own anxiety and panic attacks, and went on an incisive investigative journey.
The style is as clear and accessible as you’d expect of a journalist, and presents a very human exploration, nonetheless organized in a way that will be useful to the reader.
It’s said that “experience is a great teacher, but she sends hefty bills”. In this case as in many, it’s good to learn from someone else’s experience!
By the end of the book, you’ll have a good grounding in most approaches to dealing with anxiety and panic attacks, and an idea of efficacy/applicability, and what to expect.
Bottom line: without claiming any magic bullet, this book presents six key strategies that Gutman found to work, along with his experiences of what didn’t. Valuable reading if you want to curb your own anxiety, or want to be able to help/support someone else with theirs.

Avocado Oil vs Olive Oil – 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 avocado oil to olive oil, we picked the olive oil.
Why?
Avocados and olives are both very healthy foods. However, when they are made into oils, there’s an important distinguishing factor:
Olive oil usually retains a lot of the micronutrients from the olives (including vitamins E and K), whereas no measurable micronutrients usually remain in avocado oil.
So while both olive oil and avocado oil have a similar (excellent; very heart-healthy!) lipids profile, the olive oil has some bonuses that the avocado oil doesn’t.
We haven’t written about the nutritional profiles of either avocados or olives yet, but here’s what we had to say on the different kinds of olive oil available:
And here’s an example of a good one on Amazon, for your convenience 😎
