Most books on the topic of longevity focus on such things as diet and exercise, and indeed, those are of course important things. But what of psychological and sociological factors?
Dr. Friedman and Dr. Martin look at a landmark longitudinal study, following a large group of subjects from childhood into old age. Looking at many lifestyle factors and life events, they crunched the numbers to see what things really made the biggest impact on healthy longevity.
A strength of the book is that this study had a huge amount of data—a limitation of the book is that it often avoids giving that concrete data, preferring to say “many”, “a majority”, “a large minority”, “some”, and so forth.
However, the conclusions from the data seem clear, and include many observations such as:
- conscientiousness is a characteristic that not only promotes healthy long life, but also can be acquired as time goes by (some “carefree” children became “conscientious” adults)
- resilience is a characteristic that promotes healthy long life—but tends to only be “unlocked” by adversity
- men tend to live longer if married—women, not so much
- religion and spirituality are not big factors in healthy longevity—but social connections (that may or may not come with such) do make a big difference
Bottom line: if you’d like to know which of your decisions are affecting your healthy longevity (beyond the obvious diet, exercise, etc), this is a great book for collating that information and presenting, in essence, a guideline for a long healthy life.

War in Ukraine affected wellbeing worldwide, but people’s speed of recovery depended on their personality
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 war in Ukraine has had impacts around the world. Supply chains have been disrupted, the cost of living has soared and we’ve seen the fastest-growing refugee crisis since World War II. All of these are in addition to the devastating humanitarian and economic impacts within Ukraine.
Our international team was conducting a global study on wellbeing in the lead up to and after the Russian invasion. This provided a unique opportunity to examine the psychological impact of the outbreak of war.
As we explain in a new study published in Nature Communications, we learned the toll on people’s wellbeing was evident across nations, not just in Ukraine. These effects appear to have been temporary – at least for the average person.
But people with certain psychological vulnerabilities struggled to recover from the shock of the war.
Tracking wellbeing during the outbreak of war
People who took part in our study completed a rigorous “experience-sampling” protocol. Specifically, we asked them to report their momentary wellbeing four times per day for a whole month.
Data collection began in October 2021 and continued throughout 2022. So we had been tracking wellbeing around the world during the weeks surrounding the outbreak of war in February 2022.
We also collected measures of personality, along with various sociodemographic variables (including age, gender, political views). This enabled us to assess whether different people responded differently to the crisis. We could also compare these effects across countries.
Our analyses focused primarily on 1,341 participants living in 17 European countries, excluding Ukraine itself (44,894 experience-sampling reports in total). We also expanded these analyses to capture the experiences of 1,735 people living in 43 countries around the world (54,851 experience-sampling reports) – including in Australia.
A global dip in wellbeing
On February 24 2022, the day Russia invaded Ukraine, there was a sharp decline in wellbeing around the world. There was no decline in the month leading up to the outbreak of war, suggesting the change in wellbeing was not already occurring for some other reason.
However, there was a gradual increase in wellbeing during the month after the Russian invasion, suggestive of a “return to baseline” effect. Such effects are commonly reported in psychological research: situations and events that impact our wellbeing often (though not always) do so temporarily.
Unsurprisingly, people in Europe experienced a sharper dip in wellbeing compared to people living elsewhere around the world. Presumably the war was much more salient for those closest to the conflict, compared to those living on an entirely different continent.
Interestingly, day-to-day fluctuations in wellbeing mirrored the salience of the war on social media as events unfolded. Specifically, wellbeing was lower on days when there were more tweets mentioning Ukraine on Twitter/X.
Our results indicate that, on average, it took around two months for people to return to their baseline levels of wellbeing after the invasion.
Different people, different recoveries
There are strong links between our wellbeing and our individual personalities.
However, the dip in wellbeing following the Russian invasion was fairly uniform across individuals. None of the individual factors assessed in our study, including personality and sociodemographic factors, predicted people’s response to the outbreak of war.
On the other hand, personality did play a role in how quickly people recovered. Individual differences in people’s recovery were linked to a personality trait called “stability”. Stability is a broad dimension of personality that combines low neuroticism with high agreeableness and conscientiousness (three traits from the Big Five personality framework).
Stability is so named because it reflects the stability of one’s overall psychological functioning. This can be illustrated by breaking stability down into its three components:
- low neuroticism describes emotional stability. People low in this trait experience less intense negative emotions such as anxiety, fear or anger, in response to negative events
- high agreeableness describes social stability. People high in this trait are generally more cooperative, kind, and motivated to maintain social harmony
- high conscientiousness describes motivational stability. People high in this trait show more effective patterns of goal-directed self-regulation.
So, our data show that people with less stable personalities fared worse in terms of recovering from the impact the war in Ukraine had on wellbeing.
In a supplementary analysis, we found the effect of stability was driven specifically by neuroticism and agreeableness. The fact that people higher in neuroticism recovered more slowly accords with a wealth of research linking this trait with coping difficulties and poor mental health.
These effects of personality on recovery were stronger than those of sociodemographic factors, such as age, gender or political views, which were not statistically significant.
Overall, our findings suggest that people with certain psychological vulnerabilities will often struggle to recover from the shock of global events such as the outbreak of war in Ukraine.

Why You Probably Need More Sleep
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.
Sleep: yes, you really do still need it!
We asked you how much sleep you usually get, and got the above-pictured, below-described set of responses:
- A little of a third of all respondents selected the option “< 7 hours”
- However, because respondents also selected options such as < 6 hours, < 5 hours, and < 4 hours, so if we include those in the tally, the actual total percentage of respondents who reported getting under 7 hours, is actually more like 62%, or just under two thirds of all respondents.
- Nine respondents, which was about 5% of the total, reported usually getting under 4 hours sleep
- A little over quarter of respondents reported usually getting between 7 and 8 hours sleep
- Fifteen respondents, which was a little under 10% of the total, reported usually getting between 8 and 9 hours of sleep
- Three respondents, which was a little under 2% of the total, reported getting over 9 hours of sleep
- In terms of the classic “you should get 7–9 hours sleep”, approximately a third of respondents reported getting this amount.
You need to get 7–9 hours sleep: True or False?
True! Unless you have a (rare!) mutated ADRB1 gene, which reduces that.
The way to know whether you have this, without genomic testing to know for sure, is: do you regularly get under 6.5 hours sleep, and yet continue to go through life bright-eyed and bushy-tailed? If so, you probably have that gene. If you experience daytime fatigue, brain fog, and restlessness, you probably don’t.
About that mutated ADRB1 gene:
NIH | Gene identified in people who need little sleep
Quality of sleep matters as much as duration, and a lot of studies use the “RU-Sated” framework, which assesses six key dimensions of sleep that have been consistently associated with better health outcomes. These are:
- regularity / usual hours
- satisfaction with sleep
- alertness during waking hours
- timing of sleep
- efficiency of sleep
- duration of sleep
But, that doesn’t mean that you can skimp on the last one if the others are in order. In fact, getting a good 7 hours sleep can reduce your risk of getting a cold by three or four times (compared with six or fewer hours):
Behaviorally Assessed Sleep and Susceptibility to the Common Cold
^This study was about the common cold, but you may be aware there are more serious respiratory viruses freely available, and you don’t want those, either.
Napping is good for the health: True or False?
True or False, depending on how you’re doing it!
If you’re trying to do it to sleep less in total (per polyphasic sleep scheduling), then no, this will not work in any sustainable fashion and will be ruinous to the health. We did a Mythbusting Friday special on specifically this, a while back:
Could Just Two Hours Sleep Per Day Be Enough?
PS: you might remember Betteridge’s Law of Headlines
If you’re doing it as a energy-boosting supplement to a reasonable night’s sleep, napping can indeed be beneficial to the health, and can give benefits such as:
However! There is still a right and a wrong way to go about it, and we wrote about this previously, for a Saturday Life Hacks edition of 10almonds:
How To Nap Like A Pro (No More “Sleep Hangovers”!)
As we get older, we need less sleep: True or False
False, with one small caveat.
The small caveat: children and adolescents need 9–12 hours sleep because, uncredited as it goes, they are doing some seriously impressive bodybuilding, and that is exhausting to the body. So, an adult (with a normal lifestyle, who is not a bodybuilder) will tend to need less sleep than a child/adolescent.
But, the statement “As we get older, we need less sleep” is generally taken to mean “People in the 65+ age bracket need less sleep than younger adults”, and this popular myth is based on anecdotal observational evidence: older people tend to sleep less (as our survey above shows! For any who aren’t aware, our readership is heavily weighted towards the 60+ demographic), and still continue functioning, after all.
Just because we survive something with a degree of resilience doesn’t mean it’s good for us.
In fact, there can be serious health risks from not getting enough sleep in later years, for example:
Sleep deficiency promotes Alzheimer’s disease development and progression
Want to get better sleep?
What gets measured, gets done. Sleep tracking apps can be a really good tool for getting one’s sleep on a healthier track. We compared and contrasted some popular ones:

Walking… Better.

Walking… Better.
We recently reviewed “52 Ways To Walk” by Annabel Streets. You asked us to share some more of our learnings from that book, and… Obviously we can’t do all 52, nor go into such detail, but here are three top tips inspired by that book…
Walk in the cold!
While cold weather is often seen as a reason to not walk, in fact, it has numerous health benefits, the most exciting of which might be:
Walking in the cold causes us to convert white and yellow fat into the healthier brown fat. If you didn’t know about this, neither did scientists until about 15 years ago.
In fact, scientists didn’t even know that adult humans could even have brown adipose tissue! It was really quite groundbreaking.
In case you missed it: The Changed Metabolic World with Human Brown Adipose Tissue: Therapeutic Visions
Work while you walk!
Obviously this is only appropriate for some kinds of work… but if in your life you have any kind of work that is chiefly thinking, a bunch of it can be done while walking.
Open your phone’s note-taking app, lock the screen and pocket your phone, and think on some problem that you need to solve. Whenever you have an “aha” moment, take out your phone and make a quick note on the go.
For that matter, if you have the money and space (or are fortunate to have an employer disposed towards facilitating such), you could even set up a treadmill desk… At worst, it wouldn’t harm your work (and it’ll be a LOT better than sitting for so long).
Walk within an hour of waking!
No, this doesn’t mean that if you don’t get out of the house within 60 minutes you say “Oh no, missed the window, guess it’s a day in today”
But it does mean: in the evening, make preparations to head out first thing in the morning. Set out your clothes and appropriate footwear, find your flask to fill with the beverage of your choice in the morning and set that with them.
Then, when morning arrives… do your morning necessaries (e.g. some manner of morning ablutions and perhaps a light breakfast), make that drink for your flask, and hit the road.
Why? We’ll tell you a secret:
You ever wondered why some people seem to be more able to keep a daylight-regulated circadian rhythm than others? It’s not just about smartphones and coffees…
This study found that getting sunlight (not electric light, not artificial sunlight, but actual sunlight, from the sun, even if filtered through partial cloud) between 08:30—09:00 resulted in higher levels of a protein called PER2. PER2 is critical for setting circadian rhythms, improving metabolism, and fortifying blood vessels.
Besides, on a more simplistic level, it’s also a wonderful and energizing start to a healthy and productive day!

When can my baby drink cow’s milk? It’s sooner than you think
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.
Parents are often faced with well-meaning opinions and conflicting advice about what to feed their babies.
The latest guidance from the World Health Organization (WHO) recommends formula-fed babies can switch to cow’s milk from six months. Australian advice says parents should wait until 12 months. No wonder some parents, and the health professionals who advise them, are confused.
So what do parents need to know about the latest advice? And when is cow’s milk an option?
What’s the updated advice?
Last year, the WHO updated its global feeding guideline for children under two years old. This included recommending babies who are partially or totally formula fed can have whole animal milks (for example, full-fat cow’s milk) from six months.
This recommendation was made after a systematic review of research by WHO comparing the growth, health and development of babies fed infant formula from six months of age with those fed pasteurised or boiled animal milks.
The review found no evidence the growth and development of babies who were fed infant formula was any better than that of babies fed whole, fresh animal milks.
The review did find an increase in iron deficiency anaemia in babies fed fresh animal milk. However, WHO noted this could be prevented by giving babies iron-rich solid foods daily from six months.
On the strength of the available evidence, the WHO recommended babies fed infant formula, alone or in addition to breastmilk, can be fed animal milk or infant formula from six months of age.
The WHO said that animal milks fed to infants could include pasteurised full-fat fresh milk, reconstituted evaporated milk, fermented milk or yoghurt. But this should not include flavoured or sweetened milk, condensed milk or skim milk.
If you’re choosing cow’s milk for your baby, make sure it’s whole milk rather than skim milk. Mr Adi/Shutterstock Why is this controversial?
Australian government guidelines recommend “cow’s milk should not be given as the main drink to infants under 12 months”. This seems to conflict with the updated WHO advice. However, WHO’s advice is targeted at governments and health authorities rather than directly at parents.
The Australian dietary guidelines are under review and the latest WHO advice is expected to inform that process.
OK, so how about iron?
Iron is an essential nutrient for everyone but it is particularly important for babies as it is vital for growth and brain development. Babies’ bodies usually store enough iron during the final few weeks of pregnancy to last until they are at least six months of age. However, if babies are born early (prematurely), if their umbilical cords are clamped too quickly or their mothers are anaemic during pregnancy, their iron stores may be reduced.
Cow’s milk is not a good source of iron. Most infant formula is made from cow’s milk and so has iron added. Breastmilk is also low in iron but much more of the iron in breastmilk is taken up by babies’ bodies than iron in cow’s milk.
Babies should not rely on milk (including infant formula) to supply iron after six months. So the latest WHO advice emphasises the importance of giving babies iron-rich solid foods from this age. These foods include:
- meat
- eggs
- vegetables, including beans and green leafy vegetables
- pulses, including lentils
- ground seeds and nuts (such as peanut or other nut butters, but with no added salt or sugar).
You may have heard that giving babies whole cow’s milk can cause allergies. In fact, whole cow’s milk is no more likely to cause allergies than infant formula based on cow’s milk.
If you’re introducing cow’s milk at six months, offer iron-rich foods too, such as meat or lentils. pamuk/Shutterstock What are my options?
The latest WHO recommendation that formula-fed babies can switch to cow’s milk from six months could save you money. Infant formula can cost more than five times more than fresh milk (A$2.25-$8.30 a litre versus $1.50 a litre).
For families who continue to use infant formula, it may be reassuring to know that if infant formula becomes hard to get due to a natural disaster or some other supply chain disruption fresh cow’s milk is fine to use from six months.
It is also important to know what has not changed in the latest feeding advice. WHO still recommends infants have only breastmilk for their first six months and then continue breastfeeding for up to two years or more. It is also still the case that infants under six months who are not breastfed or who need extra milk should be fed infant formula. Toddler formula for children over 12 months is not recommended.
All infant formula available in Australia must meet the same standard for nutritional composition and food safety. So, the cheapest infant formula is just as good as the most expensive.
What’s the take-home message?
The bottom line is your baby can safely switch from infant formula to fresh, full-fat cow’s milk from six months as part of a healthy diet with iron-rich foods. Likewise, cow’s milk can also be used to supplement or replace breastfeeding from six months, again alongside iron-rich foods.
If you have questions about introducing solids your GP, child health nurse or dietitian can help. If you need support with breastfeeding or starting solids you can call the National Breastfeeding Helpline (1800 686 268) or a lactation consultant.

These are not a necessary “if this then this” equation, but rather a “if this, then probably this”, and it’s a cue to try upping that thing in your diet, and if that doesn’t quickly fix it, get some tests done:
- White bumps on the skin: vitamin A, omega 3
- Craving sour foods: vitamin C
- Restless leg syndrome: iron, magnesium
- Cracked lips: vitamin B2
- Tingling hands and feet: vitamin B12
- Easy bruising: vitamin K and vitamin C
- Canker sores: vitamin B9 (folate), vitamin B12, iron
- Brittle or misshapen nails: vitamin B7 (biotin)
- Craving salty foods: sodium, potassium
- Prematurely gray hair: copper, vitamin B9 (folate), vitamin B12
- Dandruff: omega 3, zinc, vitamin B6
- Craving ice: iron

Tranquility by Tuesday?
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.
I Know How She Does It: How Successful Women Make The Most of Their Time
This is Laura Vanderkam, author of “Tranquility By Tuesday” (amongst other books). Her “thing” is spending more time on what’s important, and less on what isn’t. Sounds simple, but she’s made a career out of it, so condensed here for you are…
Laura’s 7 Keys To Productivity
Key One: Plan your weeks on Fridays
You don’t want your Monday morning to be a “James Bond intro” (where everything is already in action and you’re just along for the ride, trying to figure out what’s going on). So, take some time last thing each Friday, to plan ahead for the following week!
Key Two: Measure what matters
Whatever that means to you. Laura tracks her use of time in half-hour blocks, and likes keeping track of streaks. For her, that means running daily and keeping a log of it. She also keeps track of the books she reads. For someone else it could be music practice, or a Duolingo streak, or eating fruit each day.
On which note…
“Dr. Greger’s Daily Dozen” is simpler than most nutrition trackers (where you must search for everything you eat, or scan barcodes for all ingredients).
Instead, it keeps track of whether you are having certain key health-giving foods often enough to maintain good health.
We might feature his method in a future edition of 10almonds, but for now, check the app out for yourself here:
Get Dr. Greger’s Daily Dozen on iOS / Get Dr. Greger’s Daily Dozen on Android
Dr. Greger’s Daily Dozen @ Nutrition Facts
Key Three: Figure out 2–3 “anchor” events for the weekend
Otherwise, it can become a bit of a haze and on Monday you find yourself thinking “where did the weekend go?”. So, plan some stuff! It doesn’t have to be anything out-of-this-world, just something that you can look forward to in advance and remember afterwards. It could be a meal out with your family, or a session doing some gardening, or a romantic night in with your partner. Whatever makes your life “living” and not passing you by!
Key Four: Tackle the toughest work first
You’ve probably heard about “swallowing frogs”. If not, there are various versions, usually attributed to Mark Twain.
Here’s one:
“If it’s your job to eat a frog, it’s best to do it first thing in the morning. And if it’s your job to eat two frogs, it’s best to eat the biggest one first.”
Top Productivity App “ToDoist” has an option for this, by the way!
Laura’s key advice here is: get the hard stuff done now! Before you get distracted or tired and postpone it to tomorrow (and then lather rinse repeat, so it never gets done)
10almonds Tip:
“But what if something’s really important but not as pressing as some less important, but more urgent tasks?”
Simple!
Set a timer (we love the Pomodoro method, by the way) and do one burst of the important-but-not-urgent task first. Then you can get to the more urgent stuff.
Repeat each day until the important-but-not-urgent task is done!
The 10almonds Team
Key Five: Use bits of time well
If, like many of us, you’ve a neverending “to read” list, use the 5–10 minute breaks that get enforced upon us periodically through the day!
- Use those few minutes before a meeting/phonecall!
- Use the time you spend waiting for public transport or riding on it!
- Use the time you spent waiting for a family member to finish doing a thing!
All those 5–10 minute bits soon add up… You might as well spend that time reading something you know will add value to your life, rather than browsing social media, for example.
Key Six: Make very short daily to-do lists
By “short”, Laura considers this “under 10 items”. Do this as the last part of your working day, ready for tomorrow. Not at bedtime! Bedtime is for winding down, not winding up
Key Seven: Have a bedtime
Laura shoots for 10:30pm, but whatever works for you and your morning responsibilities. Your morning responsibilities aren’t tied to a specific time? Lucky you, but try to keep a bedtime anyway. Otherwise, your daily rhythm can end up sliding around the clock, especially if you work from home!
