Mobility As A Sporting Pursuit
As we get older, it becomes increasingly important to treat life like a sporting event. By this we mean:
As an “athlete of life”, there are always events coming up for which we need to train. Many of these events will be surprise tests!
Such events/tests might include:
- Not slipping in the shower and breaking a hip (or worse)
- Reaching an item from a high shelf without tearing a ligament
- Getting out of the car at an awkward angle without popping a vertebra
- Climbing stairs without passing out light-headed at the top
- Descending stairs without making it a sled-ride-without-a-sled
…and many more.
Train for these athletic events now
Not necessarily this very second; we appreciate you finishing reading first. But, now generally in your life, not after the first time you fail such a test; it can (and if we’re not attentive: will) indeed happen to us all.
With regard to falling, you might like to revisit our…
…which covers how to not fall, and to not injure yourself if you do.
You’ll also want to be able to keep control of your legs (without them buckling) all the way between standing and being on the ground.
Slav squats or sitting squats (same exercise, different names, amongst others) are great for building and maintaining this kind of strength and suppleness:
(Click here for a refresher if you haven’t recently seen Zuzka’s excellent video explaining how to do this, especially if it’s initially difficult for you, “The Most Anti-Aging Exercise”)
this exercise is, by the way, great for pretty much everything below the waist!
You will also want to do resistance exercises to keep your body robust:
Resistance Is Useful! (Especially As We Get Older)
And as for those shoulders? If it is convenient for you to go swimming, then backstroke is awesome for increasing and maintaining shoulder mobility (and strength).
If swimming isn’t a viable option for you, then doing the same motion with your arms, while standing, will build the same flexibility. If you do it while holding a small weight (even just 1kg is fine, but feel free to increase if you so wish and safely can) in each hand will build the necessary strength as you go too.
As for why even just 1kg is fine: read on
About that “and strength”, by the way…
Stretching is not everything. Stretching is great, but mobility without strength (in that joint!) is just asking for dislocation.
You don’t have to be built like the Terminator, but you do need to have the structural integrity to move your body and then a little bit more weight than that (or else any extra physical work could be enough to tip you to breaking point) without incurring damage from the strain. So, it needs to not be a strain! See again, the aforementioned resistance exercises.
That said, even very gentle exercise helps too; see for example the impact of walking on osteoporosis:
Living near green spaces linked to higher bone density and lower osteoporosis risk
and…
So you don’t have to run marathons—although you can if you want:
Marathons in Mid- and Later-Life
…to keep your hips and more in good order.

The Sleep Solution – by Dr. Chris Winter
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’s blurb contains a bold claim:
❝If you want to fix your sleep problems, Internet tips and tricks aren’t going to do it for you. You need to really understand what’s going on with your sleep—both what your problems are and how to solve them.❞
So, how well does it deliver, on the strength of being a whole book rather than an Internet article?
Well, for sure we wouldn’t have the room to include all the information that Dr. Winter does, in one of our main feature articles here (we’d need to spread it out over several weeks, at least).
He examines very thoroughly what is going on with sleep, sleep disturbance, and sleep deprivation. What’s going on with the different phases of sleep (far more than your phone’s sleep app will), and how imbalances in these can cause problems.
While the usual sleep hygiene tips do get a mention, he broadly assumes we know that part already. Instead, he focuses on aligning as many components as possible of our rich and interesting circadian rhythm. Yes, even if that means clawing our way out of insomnia and/or a bad sleep schedule (or lack of coherent sleep schedule) first. He gives plenty of practical advice on how to do that.
Bottom line: if you’d like to more deeply understand sleep, what is or isn’t wrong with yours, and how you can fix it, this book is a great resource.

HBD: The Human Being Diet – by Petronella Ravenshear
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 don’t often review diet books, so why did this one catch our attention? The answer lies in its comprehensive nature without being excessively long and complex.
Ravenshear (a nutritionist) brings a focus on metabolic balance, and what will and won’t work for keeping it healthy.
The first part of the book is mostly informational; covering such things as blood sugar balance, gut health, hormones, and circadian rhythm considerations, amongst others.
The second, larger part of the book is mostly instructional; do this and that, don’t do the other, guidelines on quantities and timings, and what things may be different for some people, and what to do about those.
The style is conversational and light, but well-grounded in good science.
Bottom line: if you’d like a “one-stop shop” for giving your diet an overhaul, this book is a fine choice.

The Sweet Truth About Glycine
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.
Make Your Collagen Work Better
This is Dr. James Nicolantonio. He’s a doctor of pharmacy, and a research scientist. He has a passion for evidence-based nutrition, and has written numerous books on the subject.
Controversy! Dr. DiNicolatonio’s work has included cardiovascular research, in which field he has made the case for increasing (rather than decreasing) the recommended amount of salt in our diet. This, of course, goes very much against the popular status quo.
We haven’t reviewed that research so we won’t comment on it here, but we thought it worth a mention as a point of interest. We’ll investigate his claims in that regard another time, though!
Today, however, we’ll be looking at his incisive, yet not controversial, work pertaining to collagen and glycine.
A quick recap on collagen
We’ve written about collagen before, and its importance for maintaining… Well, pretty much most of our body, really, buta deficiency in collagen can particularly weaken bones and joints.
On a more surface level, collagen’s also important for healthy elastic skin, and many people take it for that reason alone,
Since collagen is found only in animals, even collagen supplements are animal-based (often marine collagen or bovine collagen). However, if we don’t want to consume those, we can (like most animals) synthesize it ourselves from the relevant amino acids, which we can get from plants (and also laboratories, in some cases).
You can read our previous article about this, here:
We Are Such Stuff As Fish Are Made Of
What does he want us to know about collagen?
We’ll save time and space here: first, he’d like us to know the same as what we said in our article above
However, there is also more:
Let’s assume that your body has collagen to process. You either consumed it, or your body has synthesized it. We’ll skip describing the many steps of collagen synthesis, fascinating as that is, and get to the point:
When our body weaves together collagen fibrils out of the (triple-helical) collagen molecules…
- the cross-linking of the collagen requires lysyl oxidase
- the lysyl oxidase (which we make inside us) deanimates some other amino acids yielding aldehydes that allow the stable cross-links important for the high tensile strength of collagen, but to do that, it requires copper
- in order to use the copper it needs to be in its reduced cuprous form and that requires vitamin C
- but moving it around the body requires vitamin A
So in other words: if you are taking (or synthesizing) collagen, you also need copper and vitamins A and C.
However! Just to make things harder, if you take copper and vitamin C together, it’ll reduce the copper too soon in the wrong place.
Dr. DiNicolantonio therefore advises taking vitamin C after copper, with a 75 minutes gap between them.
What does he want us to know about glycine?
Glycine is one of the amino acids that makes up collagen. Specifically, it makes up every third amino acid in collagen, and even more specifically, it’s also the rate-limiting factor in the formation of glutathione, which is a potent endogenous (i.e., we make it inside us) antioxidant that works hard to fight inflammation inside the body.
What this means: if your joints are prone to inflammation, being glycine-deficient means a double-whammy of woe.
As well as being one of the amino acids most key to collagen production, glycine has another collagen-related role:
First, the problem: as we age, glycated collagen accumulates in the skin and cartilage (that’s bad; there is supposed to be collagen there, but not glycated).
More on glycation and what it is and why it is so bad:
Are You Eating Advanced Glycation End-Products? The Trouble Of The AGEs
Now, the solution: glycine suppresses advanced glycation end products, including the glycation of collagen.
See for example:
With these three important functions of glycine in mind…
Dr. DiNicolantonio therefore advises getting glycine at a dose of 100mg/kg/day. So, if you’re the same size as this rather medium-sized writer, that means 7.2g/day.
Where can I get it?
Glycine is found in many foods, including gelatin for those who eat that, eggs for the vegetarians, and spinach for vegans.
However, if you’d like to simply take it as a supplement, here’s an example product on Amazon
(the above product is not clear whether it’s animal-derived or not, so if that’s important to you, shop around. This writer got some locally that is certified vegan, but is in Europe rather than N. America, which won’t help most of our subscribers)
Note: pure glycine is a white crystalline powder that has the same sweetness as glucose. Indeed, that is how it got its name, from the Greek “γλυκύς”, pronounced /ɡly.kýs/, meaning “sweet”. Yes, same etymology as glucose.
So don’t worry that you’ve been conned if you order it and think “this is sugar!”; it just looks and tastes the same.
That does mean you should buy from a reputable source though, as a con would be very easy!
this does also mean that if you like a little sugar/sweetener in your tea or coffee, glycine can be used as a healthy substitute.
If you don’t like sweet tastes, then, condolences. This writer pours two espresso coffees (love this decaffeinated coffee that actually tastes good), puts the glycine in the first, and then uses the second to get rid of the sweet taste of the first. So that’s one way to do it.
Enjoy (if you can!)

Get Better Sleep: Beyond The Basics
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.
First though, for the sake of being methodical, let’s quickly note the basics:
- Aim for 7–9 hours per night
- Set a regular bedtime and (equally important!) regular getting-up time
- Have a 2-hour wind-down period before bed, to decompress from any stresses of the day
- Minimal device/screen usage before bed
- Abstain from stimulants for as long before bed as reasonably possible (caffeine elimination halflife is 4–8 hours depending on your genes, call it 6 hours average to eliminate half (not the whole lot), and you’ll see it’s probably best to put a cap on it earlier rather than later).
- Abstain from alcohol, ideally entirely, but allow at least 1hr/unit before bed. So for example, 1hr for a 1oz single shot of spirits, or 2–3 hours for a glass of wine (depending on size), or 3–4 hours for a martini (depending on recipe). Not that that is not the elimination time, nor even the elimination halflife of alcohol, it’s just a “give your body a chance at least” calculation. If you like to have a drink to relax before bed, then well, only you can decide what you like more: that or actually getting restorative sleep.
- Consider a warm bath/shower before bed, if that suits your schedule.
- Wash and change your bedsheets more often than seems necessary. Or if that’s too onerous, at least change the pillowcases more often, which makes quite a difference already.
- Lower the temperature of your bedroom shortly before bedtime; this will help cue the body to produce melatonin
- Make your bedroom as dark as reasonably possible. Invest in blackout blinds/curtains, and remove any pesky electronics, or at least cover their little LEDs if it’s something that reasonably needs to remain on.
Ok, now, onwards…
Those 7–9 hours? Yes, it goes for you too.
A lot of people mistake getting 6 hours sleep per night for only needing 6 hours sleep per night. Sure, you may still be alive after regularly getting 6 hours, but (unless you have a rare mutation of the ADRB1 gene) it will be causing harm, and yes, that includes later in life; we don’t stop needing so much sleep, even stop getting it:
Why You Probably Need More Sleep
With this in mind, it becomes important to…
Prioritize your sleep—which means planning for it!
When does your bedtime routine start? According to sleep scientist Dr. Lisa Matricciani, it starts before breakfast. This is because the things we do earlier in the day can greatly affect the amount (and quality) of sleep we get later. For example, a morning moderate-to-intense exercise session greatly improves sleep at night:
Planning Ahead For Better Sleep
As for quality, that is as important as quantity, and it’s not just about “soundness” of sleep:
The 6 Dimensions Of Sleep (And Why They Matter)
“What gets measured, gets done” goes for sleep too
Sleep-deprived people usually underestimate how sleep-deprived they are. This is for the same reason as why drunk people usually underestimate how drunk they are—to put it in words that go for both situations: a cognitively impaired person lacks the cognitive function to realize how cognitively impaired they are.
Here’s the science on that, by the way:
How Sleep-Deprived Are You, Really?
For that reason, we recommend using sleep-tracking software (there are many apps for that) on your phone or, ideally, a wearable device (such as a smartwatch or similar).
A benefit of doing so is that we don’t think “well, I slept from 10pm to 6am, so that’s 8 hours”, if our device tells us we slept between 10:43pm and 5:56 am with 74% sleep efficiency because we woke up many times.
As an aside, sleep efficiency should be about 85%, by the way. Why not 100%, you ask? It’s because if your body is truly out like a light for the entire night, something is wrong (either you were very sleep-deprived, or you have been drugged, that kind of thing). See also:
An unbroken night’s sleep is a myth. Here’s what good sleep looks like.
So waking up during the night is normal, and nothing to worry about per se. If you do find trouble getting back to sleep, though:
How to Fall Back Asleep After Waking Up in the Middle of the Night
Be careful about how you try to supplement sleep
This goes both for taking substances of various kinds, and napping. Some sleep aids can help, but many are harmful and/or do not really work as such; here’s a rundown of examples of those:
Safe Effective Sleep Aids For Seniors?
And when it comes to napping, timing is everything:

Kidney Beans vs Pinto Beans – 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 kidney beans to pinto beans, we picked the pinto.
Why?
Looking at the macros first, pinto beans have slightly more protein and carbs, and a lot more fiber, making them the all-round “more food per food” choice.
In the vitamins category, kidney beans have more of vitamins B3, C, and K, while pinto beans have more of vitamins B1, B2, B6, B9, E, and choline; another win for pinto beans. In kidney beans’ defense though, with the exception of vitamin E (31x more in pinto beans) the margins of difference are small for the rest of these vitamins, making kidney beans a close runner-up. Still, at least a nominal win for pinto beans here, by the numbers.
When it comes to minerals, kidney beans are not higher in any minerals, while pinto beans have more calcium, copper, magnesium, manganese, phosphorus, potassium, and selenium. In kidney beans’ defense, though, with the exception of selenium (5–6x more in pinto beans) the margins of difference are small for the rest of these minerals, making kidney beans a fine choice here too. Once again though, a winner is declarable here by the numbers, and it’s pinto beans.
Adding up the three wins makes for one big win for pinto beans. Still, enjoy either or both, because kidney beans are great too, and so is diversity!

Rebalancing Dopamine (Without “Dopamine Fasting”)
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.
Rebalancing Dopamine (Without “Dopamine Fasting”)
Credit Steve Fisch This is Dr. Anna Lembke. She’s a professor of psychiatry at Stanford, and chief of the Stanford Addiction Medicine Dual Diagnosis Clinic—as well as running her own clinical practice, and serving on the board of an array of state and national addiction-focused organizations.
Today we’re going to look at her work on dopamine management…
Getting off the hedonic treadmill
For any unfamiliar with the term, the “hedonic treadmill” is what happens when we seek pleasure, enjoy the pleasure, the pleasure becomes normalized, and now we need to seek a stronger pleasure to get above our new baseline.
In other words, much like running on a reciprocal treadmill that just gets faster the faster we run.
What Dr. Lembke wants us to know here: pleasure invariably leads to pain
This is not because of some sort of extrinsic moral mandate, nor even in the Buddhist sense. Rather, it is biology.
Pleasure and pain are processed by the same part of the brain, and if we up one, the other will be upped accordingly, to try to keep a balance.
Consequently, if we recklessly seek “highs”, we’re going to hit “lows” soon enough. Whether that’s by drugs, sex, or just dopaminergic habits like social media overuse.
Dr. Lembke’s own poison of choice was trashy romance novels, by the way. But she soon found she needed more, and more, and the same level wasn’t “doing it” for her anymore.
So, should we just give up our pleasures, and do a “dopamine fast”?
Not so fast!
It depends on what they are. Dopamine fasting, per se, does not work. We wrote about this previously:
Short On Dopamine? Science Has The Answer
However, when it comes to our dopaminergic habits, a short period (say, a couple of weeks) of absence of that particular thing can help us re-find our balance, and also, find insight.
Lest that latter sound wishy-washy: this is about realizing how bad an overuse of some dopaminergic activity had become, the better to appreciate it responsibly, going forwards.
So in other words, if your poison is, as in Dr. Lembke’s case, trashy romance novels, you would abstain from them for a couple of weeks, while continuing to enjoy the other pleasures in life uninterrupted.
Substances that create a dependency are a special case
There’s often a popular differentiation between physical addictions (e.g. alcohol) and behavioral addictions (e.g. video games). And that’s fair; physiologically speaking, those may both involve dopamine responses, but are otherwise quite different.
However, there are some substances that are physical addictions that do not create a physical dependence (e.g. sugar), and there are substances that create a physical dependence without being addictive (e.g. many antidepressants)
See also: Addiction and physical dependence are not the same thing
In the case of anything that has created a physical dependence, Dr. Lembke does not recommend trying to go “cold turkey” on that without medical advice and supervision.
Going on the counterattack
Remember what we said about pleasure and pain being processed in the same part of the brain, and each rising to meet the other?
While this mean that seeking pleasure will bring us pain, the inverse is also true.
Don’t worry, she’s not advising us to take up masochism (unless that’s your thing!). But there are very safe healthy ways that we can tip the scales towards pain, ultimately leading to greater happiness.
Cold showers are an example she cites as particularly meritorious.
As a quick aside, we wrote about the other health benefits of these, too:
A Cold Shower A Day Keeps The Doctor Away?
