Test For Whether You Will Be Able To Achieve The Splits

Some people stretch for years without being able to do the splits; others do it easily after a short while. Are there people for whom it is impossible, and is there a way to know in advance whether our efforts will be fruitful? Liv (of “LivInLeggings” fame) has the answer:
One side of the story
There are several factors that affect whether we can do the splits, including:
- arrangement of the joint itself
- length of tendons and muscles
- “stretchiness” of tendons and muscles
The latter two things, we can readily train to improve. Yes, even the basic length can be changed over time, because the body adapts.
The former thing, however (arrangement of the joint itself) is near-impossible, because skeletal changes happen more slowly than any other changes in the body. In a battle of muscle vs bone, muscle will always win eventually, and even the bone itself can be rebuilt (as the body fixes itself, or in the case of some diseases, messes itself up). However, changing the arrangement of your joint itself is far beyond the auspices of “do some stretches each day”. So, for practical purposes, without making it the single most important thing in your life, it’s impossible.
How do we know if the arrangement of our hip joint will accommodate the splits? We can test it, one side at a time. Liv uses the middle splits, also called the side splits or box splits, as an example, but the same science and the same method goes for the front splits.
Stand next to a stable elevated-to-hip-height surface. You want to be able to raise your near-side leg laterally, and rest it on the surface, such that your raised leg is now perfectly perpendicular to your body.
There’s a catch: not only do you need to still be stood straight while your leg is elevated 90° to the side, but also, your hips still need to remain parallel to the floor—not tilted up to one side.
If you can do this (on both sides, even if not both simultaneously right now), then your hip joint itself definitely has the range of motion to allow you to do the side splits; you just need to work up to it. Technically, you could do it right now: if you can do this on both sides, then since there’s no tendon or similar running between your two legs to make it impossible to do both at once, you could do that. But, without training, your nerves will stop you; it’s an in-built self-defense mechanism that’s just firing unnecessarily in this case, and needs training to get past.
If you can’t do this, then there are two main possibilities:
- Your joint is not arranged in a way that facilitates this range of motion, and you will not achieve this without devoting your life to it and still taking a very long time.
- Your tendons and muscles are simply too tight at the moment to allow you even the half-split, so you are getting a false negative.
This means that, despite the slightly clickbaity title on YouTube, this test cannot actually confirm that you can never do the middle splits; it can only confirm that you can. In other words, this test gives two possible results:
- “Yes, you can do it!”
- “We don’t know whether you can do it”

Melatonin: A Safe, Natural Sleep Aid?
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.
Melatonin: A safe sleep supplement?
Melatonin is a hormone normally made in our pineal gland. It helps regulate our circadian rhythm, by making us sleepy.
It has other roles too—it has a part to play in regulating immune function, something that also waxes and wanes as a typical day goes by.
Additionally, since melatonin and cortisol are antagonistic to each other, a sudden increase in either will decrease the other. Our brain takes advantage of this, by giving us a cortisol spike in the morning to help us wake up.
As a supplement, it’s generally enjoyed with the intention of inducing healthy, natural, restorative sleep.
Does it really induce healthy, natural, restorative, sleep?
Yes! Well, “natural” is a little subject and relative, if you’re taking it as a supplement, but it’s something your body produces naturally anyway.
Contrast with, for example, benzodiazepines (that whole family of medications with names ending in -azopan or -alozam), or other tranquilizing drugs that do not so much induce healthy sleep, but rather reduce your brain function and hopefully knock you out, and/but often have unwanted side effects, and a tendency to create dependency.
Melatonin, unlike most of those drugs, does not create dependency, and furthermore, we don’t develop tolerance to it. In other words, the same dose will continue working (we won’t need more and more).
In terms of benefits, melatonin not only reduces the time to fall asleep and increases total sleep time, but also (quite a bonus) improves sleep quality, too:
Meta-Analysis: Melatonin for the Treatment of Primary Sleep Disorders
Because it is a natural hormone rather than a drug with many side effects and interactions, it’s also beneficial for those who need good sleep and/but don’t want tranquilizing:
Any other benefits?
Yes! It can also help guard against Seasonal Affective Disorder, also called seasonal depression. Because SAD is not just about “not enough light = not enough serotonin”, but also partly about circadian rhythm and (the body is not so sure what time of day it is when there are long hours of darkness, or even, in the other hemisphere / other time of year, long hours of daylight), melatonin can help, by giving your brain something to “anchor” onto, provided you take it at the same time each day. See:
- Is seasonal affective disorder a disorder of circadian rhythms?
- The circadian basis of winter depression: the case for low-dose melatonin use
As a small bonus, melatonin also promotes HGH production (important for maintaining bone and muscle mass, especially in later life):
Anything we should worry about?
Assuming taking a recommended dose only (0.5mg–10mg per day), toxicity is highly unlikely, especially given that it has a half-life of only 40–60 minutes, so it’ll be eliminated quite quickly.
However! It does indeed induce sleepiness, so for example, don’t take melatonin and then try to drive or operate heavy machinery—or, ideally, do anything other than go to bed.
It can interfere with some medications. We mentioned that melatonin helps regulate immune function, so for example that’s something to bear in mind if you’re on immunosuppressants or otherwise have an autoimmune disorder. It can also interfere with blood pressure medications and blood thinners, and may make epilepsy meds less effective.
As ever, if in doubt, please speak with your doctor and/or pharmacist.
Where to get it?
As ever, we don’t sell it (or anything else), but for your convenience, here is an example product on Amazon.

Xylitol vs Erythritol – 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 xylitol to erythritol, we picked the xylitol.
Why?
They’re both sugar alcohols, which so far as the body is concerned are neither sugars nor alcohols in the way those words are commonly understood; it’s just a chemical term. The sugars aren’t processed as such by the body and are passed as dietary fiber, and nor is there any intoxicating effect as one might expect from an alcohol.
In terms of macronutrients, while technically they both have carbs, for all functional purposes they don’t and just have a little fiber.
In terms of micronutrients, they don’t have any.
The one thing that sets them apart is their respective safety profiles. Xylitol is prothrombotic and associated with major adverse cardiac events (CI=95, adjusted hazard ratio=1.57, range=1.12-2.21), while erythritol is also prothrombotic and more strongly associated with major adverse cardiac events (CI=95, adjusted hazard ratio=2.21, range=1.20-4.07).
So, xylitol is bad and erythritol is worse, which means the relatively “healthier” is xylitol. We don’t recommend either, though.
Studies for both:
- Xylitol is prothrombotic and associated with cardiovascular risk
- The artificial sweetener erythritol and cardiovascular event risk

Butter vs Margarine

Butter vs Margarine
Yesterday, we asked you for your (health-related) opinion on butter vs margarine, and got the above-depicted, below-described, set of responses:
- A little over 60% said butter is a health food and margarine is basically plastic with trans fats
- A little over 20% said that both are woeful and it’s better to avoid both
- A little over 10% said that margarine is a lighter option, and butter is a fast track to cardiovascular disease.
Comments included (we will summarize/paraphrase, for space):
- “…in moderation, though”
- “I’m vegan so I use vegan butter but I know it’s not great, so I use it sparingly”
- “butter is healthy if and only if it’s grass-fed”
- “margarine has unpronounceable ingredients”
To address those quickly:
- “…in moderation” is a stipulation with which one can rarely go too far wrong
- Same! Speaking for myself (your writer here, hi) and not for the company
- Grass-fed is indeed better; alas that so little of it is grass-fed, in the US!
- Butter contains eicosatrienoic acid, linolelaidic acid, and more*. Sometimes big words don’t mean that something is worse for the health, though!
So, what does the science say?
Butter is a health food: True or False?
True or False, depending on amount! Moderation is definitely key, but we’ll return to that (and why not to have more than a small amount of butter) later. But it is a rich source of many nutrients, iff it’s grass-fed, anyway.
The nutritional profile of something isn’t a thing that’s too contentious, so rather than take too much time on it, in this case we’ll point you back up to the scientific paper we linked above, or if you prefer a pop-science rendering, here’s a nice quick rundown:
7 Reasons to Switch to Grass-Fed Butter
Margarine is basically plastic with trans fats: True or False?
False and usually False now, respectively, contingently.
On the first part: chemically, it’s simply not “basically plastic” and everything in it is digestible
On the second part: it depends on the margarine, and here’s where it pays to read labels. Historically, margarines all used to be high in trans fats (which are indeed woeful for the health). Nowadays, since trans fats have such a (well-earned) bad press, there are increasingly many margarines with low (or no) trans fats, and depending on your country, it may be that all margarines no longer have such:
❝It’s a public health success story. Consumers no longer have to worry about reading product nutritional labels to see if they contain hydrogenated oils and trans fats. They can just know that they no longer do❞
Source: Margarines now nutritionally better than butter after hydrogenated oil ban
So this is one where the science is clear (trans fats are unequivocally bad), but the consumer information is not always (it may be necessary to read labels, to know whether a margarine is conforming to the new guidelines).
Butter is a fast track to cardiovascular disease: True or False?
True or False depending on amount. In moderation, predictably it’s not a big deal.
But for example, the World Health Organization recommends that saturated fats (of which butter is a generous source) make up no more than 10% of our calorie intake:
Source: Saturated fatty acid and trans-fatty acid intake for adults and children: WHO guideline
So if you have a 2000 kcal daily intake, that would mean consuming not more than 200 kcal from butter, which is approximately two tablespoons.
If you’d like a deeper look into the complexities of saturated fats (for and against), you might like our previous main feature specifically about such:

The Five Pillars Of Longevity
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 Five Pillars Of Longevity
This is Dr. Mark Hyman. He’s a medical doctor, and he’s the board president of clinical affairs of the Institute for Functional Medicine. He’s also the founder and medical director of the UltraWellness Center!
What he’d like you to know about is what he calls the “Five Pillars of Longevity”.
Now, here at 10almonds, we often talk about certain things that science finds to be good for almost any health condition, and have made a habit of referencing what we call “The Usual Five Things™” (not really a trademark, by the way—just a figure of speech), which are:
- Have a good diet
- Get good exercise
- Get good sleep
- Reduce (or eliminate) alcohol consumption
- Don’t smoke
…and when we’re talking about a specific health consideration, we usually provide sources as to why each of them are particularly relevant, and pointers as to the what/how associated with them (ie what diet is good, how to get good sleep, etc).
Dr. Hyman’s “Five Pillars of Longevity” are based on observations from the world’s “Blue Zones”, the popular name for areas with an unusually high concentration of supercentenarians—Sardinia and Okinawa being famous examples, with a particular village in each being especially exemplary.
These Five Pillars of Longevity partially overlap with ours for three out of five, and they are:
- Good nutrition
- Optimized workouts
- Reduce stress
- Get quality sleep
- Find (and live) your purpose
We won’t argue against those! But what does he have to say, for each of them?
Good nutrition
Dr. Hyman advocates for a diet he calls “pegan”, which he considers to combine the paleo and vegan diets. Here at 10almonds, we generally advocate for the Mediterranean Diet because of the mountains of evidence for it, but his approach may be similar in some ways, since it looks to consume a majority plant diet, with some unprocessed meats/fish, limited dairy, and no grains.
By the science, honestly, we stand by the Mediterranean (which includes whole grains), but if for example your body may have issues of some kind with grains, his approach may be a worthy consideration.
Optimized workouts
For Dr. Hyman, this means getting in three kinds of exercise regularly:
- Aerobic/cardio, to look after your heart health
- Resistance training (e.g. weights or bodyweight strength-training) to look after your skeletal and muscular health
- Yoga or similar suppleness training, to look after your joint health
Can’t argue with that, and it can be all too easy to fall into the trap of thinking “I’m healthy because I do x” while forgetting y and/or z! Thus, a three-pronged approach definitely has its merits.
Reduce stress
Acute stress (say, a cold shower) is can confer some health benefits, but chronic stress is ruinous to our health and it ages us. So, reducing this is critical. Dr. Hyman advocates for the practice of mindfulness and meditation, as well as journaling.
Get quality sleep
Quality here, not just quantity. As well as the usual “sleep hygiene” advices, he has some more unorthodox methods, such as the use of binaural beats to increase theta-wave activity in the brain (and thus induce more restful sleep), and the practice of turning off Wi-Fi, on the grounds that Wi-Fi signals interfere with our sleep.
We were curious about these recommendations, so we checked out what the science had to say! Here’s what we found:
- Minimal Effects of Binaural Auditory Beats for Subclinical Insomnia: A Randomized Double-Blind Controlled Study
- Spending the night next to a router – Results from the first human experimental study investigating the impact of Wi-Fi exposure on sleep
In short: probably not too much to worry about in those regards. On the other hand, worrying less, unlike those two things, is a well-established way improve sleep!
(Surprised we disagreed with our featured expert on a piece of advice? Please know: you can always rely on us to stand by what the science says; we pride ourselves on being as reliable as possible!)
Find (and live!) your purpose
This one’s an ikigai thing, to borrow a word from Japanese, or finding one’s raison d’être, as we say in English using French, because English is like that. It’s about having purpose.
Dr. Hyman’s advice here is consistent with what many write on the subject, and it’d be an interesting to have more science on, but meanwhile, it definitely seems consistent with commonalities in the Blue Zone longevity hotspots, where people foster community, have a sense of belonging, know what they are doing for others and keep doing it because they want to, and trying to make the world—or even just their little part of it—better for those who will follow.
Being bitter, resentful, and self-absorbed is not, it seems a path to longevity. But a life of purpose, or even just random acts of kindness, may well be.

Stop Overthinking – by Nick Trenton
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 exactly what it says on the tin. We are given twenty-three techniques to relieve stress, stop negative spirals, declutter your mind, and focus on the present, in the calm pursuit of good mental health and productivity.
The techniques are things like the RAIN technique above, so if you liked that, you’ll love this. Being a book rather than a newsletter, it also takes the liberty of going into much more detail—hence the 200 pages for 23 techniques. Unlike many books, it’s not packed in fluff either. It’s that perfect combination of “to the point” and “very readable”.
If you’ve read this far into the review and you’re of two minds about whether or not this book could be useful to you, then you just might be overthinking it

Gut Feelings – by Dr Will Cole
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.
More and more, science is uncovering links between our gut health and the rest of our health—including our mental health! We all know “get some fiber and consider probiotics”, but what else is there that we can do?
Quite a lot, actually. And part of it, which Dr. Cole also explores, is the fact that the gut-brain highway is a two-way street!
The book looks a lot especially at the particular relationship between shame and eating. The shame need not initially be about eating, though it can certainly end up that way too. But any kind of shame—be it relating to one’s body, work, relationship, or anything else, can not only have a direct effect on the gut, but indirect too:
Once our “eating our feelings” instinct kicks in, things can spiral from there, after all.
So, Dr. Cole walks us through tackling this from both sides—nutrition and psychology. With chapters full of tips and tricks, plus a 21-day plan (not a diet plan, a habit integration plan), this book hits shame (and inflammation, incidentally) hard and leads us into much healthier habits and cycles.
In short: if you’d like to have a better relationship with your food, improve your gut health, and/or reduce inflammation, this is definitely a book for you!
