Thriving Beyond Fifty – by Will Harlow
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 featured this author sometimes in our video section; he’s an over-50s specialist physiotherapist with a lot of very functional advice to offer.
In this book, Harlow focusses heavily on three things: mobility, strength, endurance.
You may not want to be a gymnast, powerlifter, or marathon-runner, but these things are important for us all to maintain to at least a fair degree:
- Mobility can be the difference between tweaking one’s shoulder getting something from a high shelf, or not
- Strength can be the difference between being able to get back up, or not
- Endurance can be the difference between coming back from a long day on your feet and thinking “that was a good day; I’m looking forward to tomorrow now”, or not
One of the greatest strengths of this book is its comprehensive troubleshooting aspect; if you have a weak spot, chances are this book has the remedy.
As for the style, it’s quite casual/conversational in tone, but without skimping on science and detail. It’s clear, explanatory, and helpful throughout.
Bottom line: if you’d like to maintain/improve mobility, strength, and endurance, then this book is a very recommendable resource.

Egg Whites vs Whole Eggs – 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 egg whites to whole eggs, we picked the whole eggs.
Why?
Egg whites are mostly protein. Egg yolks are mostly fat, with some protein.
However, fat ≠ bad, and the yolk is also where the choline is stored, which itself (as well as its benefits for your brain) will tend to reduce fat storage in the body.
Furthermore, the yolk contains an assortment of vitamins, minerals, and essential amino acids. After all, the yolk is there specifically to contain everything needed to turn a cluster of cells into a small bird.

Do You Have A Personalized Health Plan? (Here’s How)
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.
“Good health” is quite a broad umbrella, and while we all have a general idea of what “healthy” looks like, it’s easy to focus on some areas and overlook others.
Of course, how much one does this will still depend on one’s level of interest in health, which can change over the course of life, and (barring serious midlife health-related curveballs such as a cancer diagnosis or something) often looks like an inverse bell curve:
- As small kids, we probably barely thought about health
- As teenagers, we probably had a narrow view of health (often related to whatever is considered sexually attractive at the time)
- In our 20s, may have a bit of a health kick in which we learn and apply a lot… Which often then gets to later take a bit of a back seat to work responsibilities and so forth
- This is commonly followed by a few decades of just trying to make it to Friday by any means necessary (definite risk factor for substance abuse of various kinds), double if we have kids, triple if we have work, kids, and are also solely responsible for managing the household.
- Then just as suddenly as it is predictably, we are ambushed when approaching retirement age by a cluster of age-related increased health risks that we now get to do our best to mitigate—the focus here is “not dying early”. A lot of health education occurs at this time.
- Finally, upon retirement, we actually get the time to truly focus on our health again, and now it’s easier to learn about all aspects of health, even if now there’s a need to juggle many health issues all at once, most of which affect the others.
See also: How Likely Are You To Live To 100? ← in which we can also see a graph of 10almonds subscribers’ ages, consistent with the above
So, let’s recap, and personalize our health plan
There are often things we wish we could have focused on sooner, so now’s the time to figure out what future-you in your next decade (or later!) is going to thank you for having done now.
So, while 20-year-old us might have been focusing on fat levels or athletic performance, how much does that really help us now? (With apologies to any readers in their 20s, but also, with the bonus for you: now’s the perfect time to plan ahead!)
At 10almonds, while we cover very many health topics, we often especially focus on:
- Brain health
- Heart health
- Gut health
…because they affect everything else so much. We’ve listed them there in the order they appear in the body, but in fact it can be useful to view them upside down, because:
- Gut health is critical for good metabolic health (a happy efficient gut allows us to process nutrients, including energy, efficiently)
- Metabolic health is critical for good heart health (a nicely ticking metabolism will not strain our heart)
- Heart health is critical for good brain health (a strong heart will nourish the brain with well-oxygenated blood and the nutrients it also carries)
So, this isn’t a catch-22 at all! There is a clear starting point:
“How do I do the other bits, though?”
We have you covered here: Your Health Audit, From Head To Toe
“Wait, where’s the personalization?”
This comes once you’ve got those above things in order.
Hopefully you know what particular health risks you have—as in, particular to you.
First, you will have any current diagnoses, and a plan for treating those. Many chronic illnesses can be reversed or at least lessened with lifestyle changes, in particular, if we reduce chronic inflammation, which is implicated in countless chronic illnesses, and exacerbates most of the rest.
So: How to Prevent (or Reduce) Inflammation
The same goes for any heightened risks you have as a result of those current diagnoses.
Next, you will have any genetic health risks—so here’s where genetic testing is a good one-shot tool, to get a lot of information all in one go.
Learn more: The Real Benefit Of Genetic Testing
…and then, of course, take appropriate steps to avoid suffering the things of which you are at increased genetic risk.
Finally, you will have any personal concerns or goals—in other words, what do you want to still be able to do, later in life? It’s easy to say “everything”, but what’s most important?
This writer’s example: I want to remain mobile, free from pain, and sharp of mind.
That doesn’t mean I’ll neglect the rest of my health, but it does mean that I will regularly weigh my choices against whether they are consistent with those three things.
As for how to plan for that?
Check out: Train For The Event Of Your Life! ← this one is mostly about the mobility aspect; staying free from pain is in large part a matter of avoiding inflammation which we already discussed, and staying sharp of mind relies on the gut-heart-brain pipeline we also covered.
You can also, of course, personalize your diet per which areas of health are the most important for you:

Lychees vs Kumquats – 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 lychees to kumquats, we picked the kumquats.
Why?
In terms of macros, everything is comparable except for fiber, of which kumquats have 5–6x as much fiber, which means a very significant win for kumquats in this category.
When it comes to vitamins, lychees have slightly more of vitamins B3, B6, C, and K, while kumquats have a lot more of vitamins A and B1, and moderately more vitamins B2, B9, E, and choline. A fair win for kumquats here.
In the category of minerals, lychees have a little more copper, phosphorus, and selenium, while kumquats have 11x as much calcium, as well as a 2–3x more iron, magnesium, manganese and zinc. An easy win for kumquats.
Both fruits have great phenolic profiles, being both rich in antioxidants.
All in all, enjoy both, but if you’re going to pick one, kumquats easily win the day!

Can You Reverse Gray Hair? A Dermatologist Explains
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.
Betteridge’s Law of Headlines states “any headline that ends in a question mark can be answered by the word no“—it’s not really a universal truth, but it’s true surprisingly often, and, as board certified dermatologist “The Beauty MD” Dr. Sam Ellis explains, it’s true in this case.
But, all is not lost.
Physiological Factors
Hair color is initially determined by genes and gene expression, instructing the body to color it with melanin (brown and black) and/or pheomelanin (blonde and red). If and when the body produces less of those pigments, our hair will go gray.
Factors that affect if/when our hair will go gray include:
- Genetics: primary determinant, essentially a programmed change
- Age: related to the above, but critically, the probability of going gray in any given year increases with age
- Ethnicity: the level of melanin in our skin is an indicator of how long we are likely to maintain melanin in our hair. Black people with the darkest skintones will thus generally go gray last, whereas white people with the lightest skintones will generally go gray first, and so on for a spectrum between the two.
- Medical conditions: immune conditions such as vitiligo, thyroid disease, and pernicious anemia promote an earlier loss of pigmentation
- Stress: oxidative stress, mainly, so factors like smoking will cause earlier graying. But yes, also chronic emotional stress does lead to oxidative stress too. Interestingly, this seems to be more about norepinephrine than cortisol, though.
- Nutrient deficiencies: the body can make a lot of things, but it needs the raw ingredients. Not having the right amounts of important vitamins and minerals will result in a loss of pigmentation (amongst other more serious problems). Vitamins B6, B9, and B12 are talked about in the video, as are iron and zinc. Copper is also needed for some hair colors. Selenium is needed for good hair health in general (but not too much, as an excess of selenium paradoxically causes hair loss), and many related things will stop working properly without adequate magnesium. Hair health will also benefit a lot from plenty of vitamin B7.
So, managing the above factors (where possible; obviously some of the above aren’t things we can influence) will result in maintaining one’s hair pigment for longer. As for texture, by the way, the reason gray hair tends to have a rougher texture is not for the lack of pigment itself, but is due to decreased sebum production. Judicious use of exogenous hair oils (e.g. argan oil, coconut oil, or whatever your preference may be) is a fine way to keep your grays conditioned.
However, once your hair has gone gray, there is no definitive treatment with good evidence for reversing that, at present. Dye it if you want to, or don’t. Many people (including this writer, who has just a couple of streaks of gray herself) find gray hair gives a distinguished look, and such harmless signs of age are a privilege not everyone gets to reach, and thus may be reasonably considered a cause for celebration

Dr. Greger’s Anti-Aging Eight
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. Greger’s Anti-Aging Eight
This is Dr. Michael Greger. We’ve featured him before: Brain Food? The Eyes Have It!
This time, we’re working from his latest book, the excellent “How Not To Age”, which we reviewed all so recently. It is very information-dense, but we’re going to be focussing on one part, his “anti-aging eight”, that is to say, eight interventions he rates the most highly to slow aging in general (other parts of the book pertained to slowing eleven specific pathways of aging, or preserving specific bodily functions against aging, for example).
Without further ado, his “anti-aging eight” are…
- Nuts
- Greens
- Berries
- Xenohormesis & microRNA manipulation
- Prebiotics & postbiotics
- Caloric restriction / IF
- Protein restriction
- NAD+
As you may have noticed, some of these are things might appear already on your grocery shopping list; others don’t seem so “household”. Let’s break them down:
Nuts, greens, berries
These are amongst the most nutrient-dense and phytochemical-useful parts of the diet that Dr. Greger advocates for in his already-famous “Dr. Greger’s Daily Dozen”.
For brevity, we’ll not go into the science of these here, but will advise you: eat a daily portion of nuts, a daily portion of berries, and a couple of daily portions of greens.
Xenohormesis & microRNA manipulation
You might, actually, have these on your grocery shopping list too!
Hormesis, you may recall from previous editions of 10almonds, is about engaging in a small amount of eustress to trigger the body’s self-strengthening response, for example:
Xenohormesis is about getting similar benefits, second-hand.
For example, plants that have been grown to “organic” standards (i.e. without artificial pesticides, herbicides, fertilizers) have had to adapt to their relatively harsher environment by upping their levels of protective polyphenols and other phytochemicals that, as it turns out, are as beneficial to us as they are to the plants:
Hormetic Effects of Phytochemicals on Health and Longevity
Additionally, the flip side of xenohormesis is that some plant compounds can themselves act as a source of hormetic stress that end up bolstering us. For example:
In essence, it’s not just that it has anti-oxidant effect; it also provides a tiny oxidative-stress immunization against serious sources of oxidative stress—and thus, aging.
MicroRNA manipulation is, alas, too complex to truly summarize an entire chapter in a line or two, but it has to do with genetic information from the food that we eat having a beneficial or deleterious effect to our own health:
Diet-derived microRNAs: unicorn or silver bullet?
A couple of quick takeaways (out of very many) from Dr. Greger’s chapter on this is to spring for the better quality olive oil, and skip the cow’s milk:
- Impact of Phenol-Enriched Virgin Olive Oils on the Postprandial Levels of Circulating microRNAs Related to Cardiovascular Disease
- MicroRNA exosomes of pasteurized milk: potential pathogens of Western diseases
Prebiotics & Postbiotics
We’re short on space, so we’ll link you to a previous article, and tell you that it’s important against aging too:
Making Friends With Your Gut (You Can Thank Us Later)
An example of how one of Dr. Greger’s most-recommended postbiotics helps against aging, by the way:
- The mitophagy activator urolithin A is safe and induces a molecular signature of improved mitochondrial and cellular health in humans
- Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults
(Urolithin can be found in many plants, and especially those containing tannins)
See also: How to Make Urolithin Postbiotics from Tannins
Caloric restriction / Intermittent fasting
This is about lowering metabolic load and promoting cellular apoptosis (programmed cell death; sounds bad; is good) and autophagy (self-consumption; again, sounds bad; is good).
For example, he cites the intermittent fasters’ 46% lower risk of dying in the subsequent years of follow-up in this longitudinal study:
For brevity we’ll link to our previous IF article, but we’ll revisit caloric restriction in a main feature on of these days:
Fasting Without Crashing? We sort the science from the hype!
Dr. Greger favours caloric restriction over intermittent fasting, arguing that it is easier to adhere to and harder to get wrong if one has some confounding factor (e.g. diabetes, or a medication that requires food at certain times, etc). If adhered to healthily, the benefits appear to be comparable for each, though.
Protein restriction
In contrast to our recent main feature Protein vs Sarcopenia, in which that week’s featured expert argued for high protein consumption levels, protein restriction can, on the other hand, have anti-aging effects. A reminder that our body is a complex organism, and sometimes what’s good for one thing is bad for another!
Dr. Greger offers protein restriction as a way to get many of the benefits of caloric restriction, without caloric restriction. He further notes that caloric restriction without protein restriction doesn’t decrease IGF-1 levels (a marker of aging).
However, for FGF21 levels (these are good and we want them higher to stay younger), what matters more than lowering proteins in general is lowering levels of the amino acid methionine—found mostly in animal products, not plants—so the source of the protein matters:
For example, legumes deliver only 5–10% of the methionine that meat does, for the same amount of protein, so that’s a factor to bear in mind.
NAD+
This is about nicotinamide adenine dinucleotide, or NAD+ to its friends.
NAD+ levels decline with age, and that decline is a causal factor in aging, and boosting the levels can slow aging:
Therapeutic Potential of NAD-Boosting Molecules: The In Vivo Evidence
Can we get NAD+ from food? We can, but not in useful quantities or with sufficient bioavailability.
Supplements, then? Dr. Greger finds the evidence for their usefulness lacking, in interventional trials.
How to boost NAD+, then? Dr. Greger prescribes…
Exercise! It boosts levels by 127% (i.e., it more than doubles the levels), based on a modest three-week exercise bike regimen:
Skeletal muscle NAMPT is induced by exercise in humans
Another study on resistance training found the same 127% boost:

Dyslexia Test
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.
(and it’s mostly not about reading/writing!)
More than just shuffled letters
This video provides a self-test based on the Bangor Dyslexia Test (BDT). The BDT is 94% accurate in identifying dyslexia, and it includes 9 parts, with a mix of questions and tasks. Answering “yes” or struggling with tasks indicates possible dyslexia. Collecting 4+ indicators suggests dyslexia, but of course is not a replacement for official diagnosis.
It’s best to watch the video if you can, but here’s what to expect:
- Left-Right confusion: point your left hand to your right/left shoulder.
- Family history: any family members with dyslexia or struggles with reading/writing?
- Repeating numbers (order): repeat a given sequence of numbers in order.
- Letter confusion (e.g. b/d): do you confuse letters like “b” and “d” beyond age 8?
- Times tables: recite the 6, 7, and 8 times tables.
- Word manipulation: replace the letters in a word to create a new word, e.g. change “slide” (s ⇾ g) to “glide.”
- Repeating numbers (reversed): repeat a given sequence of numbers in reverse order.
- Months in reverse: recite the months of the year in reverse order.
- Subtraction: do you struggle with subtraction, e.g. 44-9 or 55-12?
Writer’s anecdote: I am not dyslexic, and/but I have an impressive level of dyscalculia (the purely numerical equivalent), to the point I’ll sometimes use a calculator to do single-digit calculations, and I am so bad at calculating ages or other differences between dates (I will have to count on my fingers or else run the severe risk of out-by-one errors). I have also been known to make mistakes counting down from 10, which really ruins dramatic tension.
In contrast, the left-right thing is interesting, because when I was first learning Arabic, I had no trouble reading/writing right-to-left, but I initially struggled so much to remember which way the “backspace” key would take me (in Arabic the backspace key backspaces to the right, despite still pointing to the left).
Anyway, for the test itself, enjoy:
