Ikigai: A Closer Look
We’ve mentioned ikigai from time to time, usually when discussing the characteristics associated with Blue Zone centenarians, for example as number 5 of…
It’s about finding one’s “purpose”. Not merely a function, but what actually drives you in life. And, if Japanese studies can be extrapolated to the rest of the world, it has a significant and large impact on mortality (other factors being controlled for); not having a sense of ikigai is associated with an approximately 47%* increase in 7-year mortality risk in the categories of cardiovascular disease and external cause mortality:
Sense of life worth living (ikigai) and mortality in Japan: Ohsaki Study
*we did a lot of averaging and fuzzy math to get this figure; the link will show you the full stats though!
In case that huge (n=43,391) study didn’t convince you, here’s another comparably-sized (n=43,117) one that found similarly, albeit framing the numbers the other way around, i.e. a comparable decrease in mortality risk for having a sense of ikigai:
This study was even longer (12 years rather than 7), so the fact that it found pretty much the same results the 7-year study we cited just before is quite compelling evidence. Again, multivariate hazard ratios were adjusted for age, BMI, drinking and smoking status, physical activity, sleep duration, education, occupation, marital status, perceived mental stress, and medical history—so all these things were effectively controlled for statistically.
Three kinds of ikigai
There are three principal kinds of ikigai:
- Social ikigai: for example, a caring role in the family or community, volunteer work, teaching
- Asocial ikigai: for example, a solitary practice of self-discipline, spirituality, or study without any particular intent to teach others
- Antisocial ikigai: for example, a strong desire to outlive an enemy, or to harm a person or group that one hates
You may be thinking: wait, aren’t those last things bad?
And… Maybe! But ikigai is not a matter of morality or even about “warm fuzzy feelings”. The fact is, having a sense of purpose increases longevity regardless of moral implications or niceness.
Nevertheless, for obvious reasons there is a lot more focus on the first two categories (social and asocial), and of those, especially the first category (social), because on a social level, “we all do well when we all do well”.
We exemplified them above, but they can be defined:
- Social: working for the betterment of society
- Asocial: working for the betterment of oneself
Of course, for many people, the same ikigai may cover both of those—often somebody who excels at something for its own sake and/but shares it with others to enrich their lives also, for example a teacher, an artist, a scientist, etc.
For it to cover both, however, requires that both parts of it are genuinely part of their feeling of ikigai, and not merely unintended consequences.
For example, a piano teacher who loves music in general and the piano in particular, and would gladly spend every waking moment studying/practising/performing, but hates having to teach it, but needs to pay the bills so teaches it anyway, cannot be said to be living any kind of social ikigai there, just asocial. And in fact, if teaching the piano is causing them to not have the time or energy to pursue it for its own sake, they might not even be living any ikigai at all.
One other thing to watch out for
There is one last stumbling block, which is that while we can find ikigai, we can also lose it! Examples of this may include:
- A professional whose job is their ikigai, until they face mandatory retirement or are otherwise unable to continue their work (perhaps due to disability, for example)
- A parent whose full-time-parent role is their ikigai, until their children leave for school, university, life in general
- A married person whose “devoted spouse” role is their ikigai, until their partner dies
For this reason, people of any age can have a “crisis of identity” that’s actually more of a “crisis of purpose”.
There are two ways of handling this:
- Have a back-up ikigai ready! For example, if your profession is your ikigai, maybe you have a hobby waiting in the wings, that you can smoothly jump ship to upon retirement.
- Embrace the fluidity of life! Sometimes, things don’t happen the way we expect. Sometimes life’s surprises can trip us up; sometimes they can leave us a sobbing wreck. But so long as life continues, there is an opportunity to pick ourselves up and decide where to go from that point. Note that this is not fatalism, by the way, it doesn’t have to be “this bad thing happened so that we could find this good thing, so really it was a good thing all along”. Rather, it can equally readily be “well, we absolutely did not want that bad thing to happen, but since it did, now we shall take it this way from here”.

Early Bird Or Night Owl? Genes vs Environment
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.
A Sliding Slope?
In Tuesday’s newsletter, we asked you how much control you believe we have over our sleep schedule, and got the above-depicted, below-described, set of responses:
- 45% said “most people can control it; some people with sleep disorders cannot
- 35% said “our genes predispose us to early/late, but we can slide it a bit
- 15% said: “going against our hardwired sleep schedules is a road to ruin”
- 5% said “anyone can adjust their sleep schedule with enough willpower”
You may be wondering: what’s with those single-digit numbers in the graph there? And the answer is: Tuesday’s email didn’t go out at the usual time due to a scheduling mistake (sorry!), which is probably what affected the number of responses (poll response levels vary, but are usually a lot higher than this).
Note: yes, this does mean most people who read our newsletter don’t vote. So, not to sound like a politician on the campaign trail, but… Your vote counts! We always love reading your comments when you add those, too—often they provide context that allow us to tailor what we focus on in our articles
However, those are the responses we got, so here we are!
What does the science say?
Anyone can adjust their sleep with enough willpower: True or False?
False, simply. It’s difficult for most people, but for many people with sleep disorders, it is outright impossible.
In a battle of narcolepsy vs willpower, for example, no amount of willpower will stop the brain from switching to sleep mode when it thinks it’s time to sleep:
❝Narcolepsy is the most common neurological cause of chronic sleepiness. The discovery about 20 years ago that narcolepsy is caused by selective loss of the neurons producing orexins sparked great advances in the field
[There is also] developing evidence that narcolepsy is an autoimmune disorder that may be caused by a T cell-mediated attack on the orexin neurons and explain how these new perspectives can inform better therapeutic approaches.❞
~ Dr. Carrie Mahoney et al. (lightly edited for brevity)
Source: The neurobiological basis of narcolepsy
For further reading, especially if this applies to you or a loved one:
Our genes predispose us to early/late, but we can slide it a bit: True or False?
True! First, about our genes predisposing us:
…and also:
Gene distinguishes early birds from night owls and helps predict time of death
Now, as for the “can slide it a bit”, this is really just a function of the general categories of “early bird” and “night owl” spanning periods of time that allow for a few hours’ wiggle-room at either side.
However, it is recommended to make any actual changes more gradually, with the Sleep Foundation going so far as to recommend 30 minutes, or even just 15 minutes, of change per day:
Sleep Foundation | How to Fix Your Sleep Schedule
Going against our hardwired sleep schedule is a road to ruin: True or False?
False, contextually. By this we mean: our “hardwired” sleep schedule is (for most of us), genetically predisposed but not predetermined.
Also, genetic predispositions are not necessarily always good for us; one would not argue, for example, for avoiding going against a genetic predisposition to addiction.
Some genetic predispositions are just plain bad for us, and genes can be a bit of a lottery.
That said, we do recommend getting some insider knowledge (literally), by getting personal genomics tests done, if that’s a viable option for you, so you know what’s really a genetic trait (and what to do with that information) and what’s probably caused by something else (and what to do with that information):

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.

‘Sleep tourism’ promises the trip of your dreams. Beyond the hype plus 5 tips for a holiday at home
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.
Imagine arriving at your hotel after a long flight and being greeted by your own personal sleep butler. They present you with a pillow menu and invite you to a sleep meditation session later that day.
You unpack in a room kitted with an AI-powered smart bed, blackout shades, blue light-blocking glasses and weighted blankets.
Holidays are traditionally for activities or sightseeing – eating Parisian pastry under the Eiffel tower, ice skating at New York City’s Rockefeller Centre, lying by the pool in Bali or sipping limoncello in Sicily. But “sleep tourism” offers vacations for the sole purpose of getting good sleep.
The emerging trend extends out of the global wellness tourism industry – reportedly worth more than US$800 billion globally (A$1.2 trillion) and expected to boom.
Luxurious sleep retreats and sleep suites at hotels are popping up all over the world for tourists to get some much-needed rest, relaxation and recovery. But do you really need to leave home for some shuteye?
RossHelen/Shutterstock Not getting enough
The rise of sleep tourism may be a sign of just how chronically sleep deprived we all are.
In Australia more than one-third of adults are not achieving the recommended 7–9 hours of sleep per night, and the estimated cost of this inadequate sleep is A$45 billion each year.
Inadequate sleep is linked to long-term health problems including poor mental health, heart disease, metabolic disease and deaths from any cause.
Can a fancy hotel give you a better sleep?
Many of the sleep services available in the sleep tourism industry aim to optimise the bedroom for sleep. This is a core component of sleep hygiene – a series of healthy sleep practices that facilitate good sleep including sleeping in a comfortable bedroom with a good mattress and pillow, sleeping in a quiet environment and relaxing before bed.
The more people follow sleep hygiene practices, the better their sleep quality and quantity.
When we are staying in a hotel we are also likely away from any stressors we encounter in everyday life (such as work pressure or caring responsibilities). And we’re away from potential nighttime disruptions to sleep we might experience at home (the construction work next door, restless pets, unsettled children). So regardless of the sleep features hotels offer, it is likely we will experience improved sleep when we are away.
Being away from home also means being away from domestic disruptions. Makistock/Shutterstock What the science says about catching up on sleep
In the short-term, we can catch up on sleep. This can happen, for example, after a short night of sleep when our brain accumulates “sleep pressure”. This term describes how strong the biological drive for sleep is. More sleep pressure makes it easier to sleep the next night and to sleep for longer.
But while a longer sleep the next night can relieve the sleep pressure, it does not reverse the effects of the short sleep on our brain and body. Every night’s sleep is important for our body to recover and for our brain to process the events of that day. Spending a holiday “catching up” on sleep could help you feel more rested, but it is not a substitute for prioritising regular healthy sleep at home.
All good things, including holidays, must come to an end. Unfortunately the perks of sleep tourism may end too.
Our bodies do not like variability in the time of day that we sleep. The most common example of this is called “social jet lag”, where weekday sleep (getting up early to get to work or school) is vastly different to weekend sleep (late nights and sleep ins). This can result in a sleepy, grouchy start to the week on Monday. Sleep tourism may be similar, if you do not come back home with the intention to prioritise sleep.
So we should be mindful that as well as sleeping well on holiday, it is important to optimise conditions at home to get consistent, adequate sleep every night.
Good sleep hygiene doesn’t require a passport. Maridav/Shutterstock 5 tips for having a sleep holiday at home
An AI-powered mattress and a sleep butler at home might be the dream. But these features are not the only way we can optimise our sleep environment and give ourselves the best chance to get a good night’s sleep. Here are five ideas to start the night right:
1. avoid bright artificial light in the evening (such as bright overhead lights, phones, laptops)
2. make your bed as comfortable as possible with fresh pillows and a supportive mattress
3. use black-out window coverings and maintain a cool room temperature for the ideal sleeping environment
4. establish an evening wind-down routine, such as a warm shower and reading a book before bed or even a “sleepy girl mocktail”
5. use consistency as the key to a good sleep routine. Aim for a similar bedtime and wake time – even on weekends.

Elon Musk says ‘disc replacement’ worked for him. But evidence this surgery helps chronic pain is lacking
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.
Last week in a post on X, owner of the platform Elon Musk recommended people look into disc replacement if they’re experiencing severe neck or back pain.
According to a biography of the billionaire, he’s had chronic back and neck pain since he tried to “judo throw” a 350-pound sumo wrestler in 2013 at a Japanese-themed party for his 42nd birthday, and blew out a disc at the base of his neck.
In comments following the post, Musk said the surgery was a “gamechanger” and reduced his pain significantly.
Musk’s original post has so far had more than 50 million views and generated controversy. So what is disc replacement surgery and what does the evidence tells us about its benefits and harms?
What’s involved in a disc replacement?
Disc replacement is a type of surgery in which one or more spinal discs (a cushion between the spine bones, also known as vertebrae) are removed and replaced with an artificial disc to retain movement between the vertebrae. Artificial discs are made of metal or a combination of metal and plastic.
Disc replacement may be performed for a number of reasons, including slipped discs in the neck, as appears to be the case for Musk.
Disc replacement is major surgery. It requires general anaesthesia and the operation usually takes 2–4 hours. Most people stay in hospital for 2–7 days. After surgery patients can walk but need to avoid things like strenuous exercise and driving for 3–6 weeks. People may be required to wear a neck collar (following neck surgery) or a back brace (following back surgery) for about 6 weeks.
Costs vary depending on whether you have surgery in the public or private health system, if you have private health insurance, and your level of coverage if you do. In Australia, even if you have health insurance, a disc replacement surgery may leave you more than A$12,000 out of pocket.
Disc replacement surgery is not performed as much as other spinal surgeries (for example, spinal fusion) but its use is increasing.
In New South Wales for example, rates of privately-funded disc replacement increased six-fold from 6.2 per million people in 2010–11 to 38.4 per million in 2019–20.
What are the benefits and harms?
People considering surgery will typically weigh that option against not having surgery. But there has been very little research comparing disc replacement surgery with non-surgical treatments.
Clinical trials are the best way to determine if a treatment is effective. You first want to show that a new treatment is better than doing nothing before you start comparisons with other treatments. For surgical procedures, the next step might be to compare the procedure to non-surgical alternatives.
Unfortunately, these crucial first research steps have largely been skipped for disc replacement surgery for both neck and back pain. As a result, there’s a great deal of uncertainty about the treatment.
There are no clinical trials we know of investigating whether disc replacement is effective for neck pain compared to nothing or compared to non-surgical treatments.
For low back pain, the only clinical trial that has been conducted to our knowledge comparing disc replacement to a non-surgical alternative found disc replacement surgery was slightly more effective than an intensive rehabilitation program after two years and eight years.
Many people experience chronic pain. Yan Krukau/Pexels Complications are not uncommon, and can include disclocation of the artificial disc, fracture (break) of the artificial disc, and infection.
In the clinical trial mentioned above, 26 of the 77 surgical patients had a complication within two years of follow up, including one person who underwent revision surgery that damaged an artery leading to a leg needing to be amputated. Revision surgery means a re-do to the primary surgery if something needs fixing.
Are there effective alternatives?
The first thing to consider is whether you need surgery. Seeking a second opinion may help you feel more informed about your options.
Many surgeons see disc replacement as an alternative to spinal fusion, and this choice is often presented to patients. Indeed, the research evidence used to support disc replacement mainly comes from studies that compare disc replacement to spinal fusion. These studies show people with neck pain may recover and return to work faster after disc replacement compared to spinal fusion and that people with back pain may get slightly better pain relief with disc replacement than with spinal fusion.
However, spinal fusion is similarly not well supported by evidence comparing it to non-surgical alternatives and, like disc replacement, it’s also expensive and associated with considerable risks of harm.
Fortunately for patients, there are new, non-surgical treatments for neck and back pain that evidence is showing are effective – and are far cheaper than surgery. These include treatments that address both physical and psychological factors that contribute to a person’s pain, such as cognitive functional therapy.
While Musk reported a good immediate outcome with disc replacement surgery, given the evidence – or lack thereof – we advise caution when considering this surgery. And if you’re presented with the choice between disc replacement and spinal fusion, you might want to consider a third alternative: not having surgery at all.

Activate Your Brain – by Scott G. Halford
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 reviewed a number of “improve your brain health” books over time, and this one’s quite different. How?
Most of the books we’ve reviewed have been focused on optimizing diet and exercise for brain health with a nod to other factors… This one focuses more on those other factors.
While this book does reference a fair bit of hard science, much of it is written more like a pop psychology book. As a result, most of the actionable advices, of which there are many, pertain to cognitive and behavioral adjustments.
And no, this is not a book of Cognitive Behavioral Therapy. It just happened to also address those two aspects.
We learn, for example, how our neurochemistry influences us—but also how we can influence our neurochemistry.
We also learn the oft-neglected (in other books!) social factors that influence brain health. Not just for our happiness, but for our productivity and peak cognitive performance too. Halford talks us through optimizing these such that we and those around us all get to enjoy the best brain benefits available to each of us.
The format of the book is that each chapter explains what you need to know for a given “activation” as the author calls it, and then an exercise to try out. With fifteen such chapters, every reader is bound to find at least something new.
Bottom line: if you want to grease those synapses in more ways than just eating some nuts and berries and getting good sleep and exercise, this book is a great resource.

Which Magnesium? (And: When?)
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 Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Good morning! I have been waiting for this day to ask: the magnesium in my calcium supplement is neither of the two versions you mentioned in a recent email newsletter. Is this a good type of magnesium and is it efficiently bioavailable in this composition? I also take magnesium that says it is elemental (oxide, gluconate, and lactate). Are these absorbable and useful in these sources? I am not interested in taking things if they aren’t helping me or making me healthier. Thank you for your wonderful, informative newsletter. It’s so nice to get non-biased information❞
Thank you for the kind words! We certainly do our best.
For reference: the attached image showed a supplement containing “Magnesium (as Magnesium Oxide & AlgaeCal® l.superpositum)”
Also for reference: the two versions we compared head-to-head were these very good options:
Magnesium Glycinate vs Magnesium Citrate – Which is Healthier?
Let’s first borrow from the above, where we mentioned: magnesium oxide is probably the most widely-sold magnesium supplement because it’s cheapest to make. It also has woeful bioavailability, to the point that there seems to be negligible benefit to taking it. So we don’t recommend that.
As for magnesium gluconate and magnesium lactate:
- Magnesium lactate has very good bioavailability and in cases where people have problems with other types (e.g. gastrointestinal side effects), this will probably not trigger those.
- Magnesium gluconate has excellent bioavailability, probably coming second only to magnesium glycinate.
The “AlgaeCal® l.superpositum” supplement is a little opaque (and we did ntoice they didn’t specify what percentage of the magnesium is magnesium oxide, and what percentage is from the algae, meaning it could be a 99:1 ratio split, just so that they can claim it’s in there), but we can say Lithothamnion superpositum is indeed an algae and magnesium from green things is usually good.
Except…
It’s generally best not to take magnesium and calcium together (as that supplement contains). While they do work synergistically once absorbed, they compete for absorption first so it’s best to take them separately. Because of magnesium’s sleep-improving qualities, many people take calcium in the morning, and magnesium in the evening, for this reason.
