How much hope can we reasonably have of reaching 100?
Yesterday, we asked you: assuming a good Health-Related Quality of Life (HRQoL), how much longer do you hope to live?

We got the above-depicted, below-described, set of responses:
- A little over 38% of respondents hope to live another 11–20 years
- A little over 31% hope to live another 31–40 years
- A little over 7% will be content to make it to the next decade
- One (1) respondent hopes to live longer than an additional 100 years
This is interesting when we put it against our graph of how old our subscribers are:
…because it corresponds inversely, right down to the gap/dent in the 40s. And—we may hypothesize—that one person under 18 who hopes to live to 120, perhaps.
This suggests that optimism remains more or less constant, with just a few wobbles that would probably be un-wobbled with a larger sample size.
In other words: most of our education-minded, health-conscious subscriber-base hope to make it to the age of 90-something, while for the most part feeling that 100+ is overly optimistic.
Writer’s anecdote: once upon a time, I was at a longevity conference in Brussels, and a speaker did a similar survey, but by show of hands. He started low by asking “put your hands up if you want to live at least a few more minutes”. I did so, with an urgency that made him laugh, and say “Don’t worry; I don’t have a gun hidden up here!”
Conjecture aside… What does the science say about our optimism?
First of all, a quick recap…
To not give you the same information twice, let’s note we did an “aging mythbusting” piece already covering:
- Aging is inevitable: True or False?
- Aging is, and always will be, unstoppable: True or False?
- We can slow aging: True or False?
- It’s too early to worry about… / It’s too late to do anything about… True or False?
- We can halt aging: True or False?
- We can reverse aging: True or False?
- But those aren’t really being younger, we’ll still die when our time is up: True or False?
You can read the answers to all of those here:
Age & Aging: What Can (And Can’t) We Do About It?
Now, onwards…
It is unreasonable to expect to live past 100: True or False?
True or False, depending on your own circumstances.
First, external circumstances: the modal average person in Hong Kong is currently in their 50s and can expect to live into their late 80s, while the modal average person in Gaza is 14 and may not expect to make it to 15 right now.
To avoid extremes, let’s look at the US, where the modal average person is currently in their 30s and can expect to live into their 70s:
United States Mortality Database
Now, before that unduly worries our many readers already in their 70s…
Next, personal circumstances: not just your health, but your socioeconomic standing. And in the US, one of the biggest factors is the kind of health insurance one has:
SOA Research Institute | Life Expectancy Calculator 2021
You may note that the above source puts all groups into a life expectancy in the 80s—whereas the previous source gave 70s.
Why is this? It’s because the SOA, whose primary job is calculating life insurance risks, is working from a sample of people who have, or are applying for, life insurance. So it misses out many people who die younger without such.
New advances in medical technology are helping people to live longer: True or False?
True, assuming access to those. Our subscribers are mostly in North America, and have an economic position that affords good access to healthcare. But beware…
On the one hand:
The number of people who live past the age of 100 has been on the rise for decades
On the other hand:
The average life expectancy in the U.S. has been on the decline for three consecutive years
COVID is, of course, largely to blame for that, though:
❝The decline of 1.8 years in life expectancy was primarily due to increases in mortality from COVID-19 (61.2% of the negative contribution).
The decline in life expectancy would have been even greater if not for the offsetting effects of decreases in mortality due to cancer (43.1%)❞
Source: National Vital Statistics Reports
The US stats are applicable to Canada, the UK, and Australia: True or False?
False: it’s not quite so universal. Differences in healthcare systems will account for a lot, but there are other factors too:
- Life expectancy in Canada fell for the 3rd year in a row. What’s happening?
- UK life expectancy lagging behind rest of G7 except the US
- Australians are living longer but what does it take to reach 100 years old?
Here’s an interesting (UK-based) tool that calculates not just your life expectancy, but also gives the odds of living to various ages (e.g. this writer was given odds of living to 87, 96, 100).
Check yours here:
Office of National Statistics | Life Expectancy Calculator
To finish on a cheery note…
Data from Italian centenarians suggests a “mortality plateau”:
❝The risk of dying leveled off in people 105 and older, the team reports online today in Science.
That means a 106-year-old has the same probability of living to 107 as a 111-year-old does of living to 112.
Furthermore, when the researchers broke down the data by the subjects’ year of birth, they noticed that over time, more people appear to be reaching age 105.❞

When Did You Last Have a Cognitive Health Check-Up?

When Did You Last Have a Cognitive Health Check-Up?
Regular health check-ups are an important part of a good health regime, especially as we get older. But after you’ve been prodded, probed, sampled and so forth… When did you last have a cognitive health check-up?
Keeping on top of things
In our recent Monday Research Review main feature about citicoline, we noted that it has beneficial effects for a lot of measures of cognitive health.
And that brought us to realize: just how on top of this are we?
Your writer here today could tell you what her sleep was like on any night in the past year, what her heart rate was like, her weight, and all that. Moods too! There’s an app for that. But cognitive health? My last IQ test was in 2001, and I forget when my last memory test was.
It’s important to know how we’re doing, or else how to we know if there has been some decline? We’ve talked previously about the benefits of brain-training of various kinds to improve cognition, so in some parts we’ll draw on the same resources today, but this time the focus is on getting quick measurements that we can retest regularly (mark the calendar!)
Some quick-fire tests
These tests are all free, quick, and accessible. Some of them will try to upsell you on other (i.e. paid) services; we leave that to your own discretion, but the things we’ll be using today are free.
Test your verbal memory
This one’s a random word list generator. It defaults to 12 words, but you can change that if you like. Memorize the words, and then test yourself by seeing how many you can write down from memory. If it gets too easy, crank up the numbers.
Test your visual memory
This one’s a series of images; the test is to click to say whether you’ve seen this exact image previously in the series or not.
Test your IQ
This one’s intended to be general purpose intelligence; in reality, IQ tests have their flaws too, but it’s not a bad metric to keep track of. Just don’t get too hung up on the outcome, and remember, your only competition is yourself!
Test your attention / focus
This writer opened this and this three other attention tests (to get you the best one) before getting distracted, noting the irony, and finally taking the test. Hopefully you can do better!
Test your creativity
This one’s a random object generator. Give yourself a set period of time (per your preference, but make a note of the time you allow yourself, so that you can use the same time period when you retest yourself at a later date) in which to list as many different possible uses for the item.
Test your musical sense
This one’s a pitch recognition test. So, with the caveat that it is partially testing your hearing as well as your cognition, it’s a good one to take and regularly retest in any case.
How often should you retest?
There’s not really any “should” here, but to offer some advice:
- If you take them too often, you might find you get bored of doing so and stop, essentially burning out.
- If you don’t take them regularly, you may forget, lose this list of tests, etc.
- Likely a good “sweet spot” is quarterly or six-monthly, but there’s nothing wrong with testing annually either.
It’s all about the big picture, after all.

Laugh Often, To Laugh Longest!

Putting The Abs Into Absurdity
We’ve talked before about the health benefits of a broadly positive outlook on life:
Optimism Seriously Increases Longevity!
…and we’re very serious about it, but that’s about optimistic life views in general, and today we’re about not just keeping good humor in questionable circumstances, but actively finding good humor in the those moments—even when the moments in question might not be generally described as good!
After all, laughter really can be the best medicine, for example:
From the roots
First a quick recap on de-toothing the psychological aspect of threats, no matter how menacing they may be:
Hello, Emotions: Time For Radical Acceptance!
…which we can then take a step further:
What’s The Worst That Could Happen?
Choose your frame
Do you remember when that hacker hacked and publicized the US Federal no-fly list, after already hacking a nationwide cloud-based security camera company, getting access to more than 150,000 companies’ and private individuals’ security cameras, amongst various other cyber crimes, mostly various kinds of fraud and data theft?
Imagine how she (age 21) must have felt, when being indicted. What do you suppose this hacker had to say for itself under such circumstances?
❝congress is investigating now 🙂
but i stay silly :3 ❞
…the latter half of which, usually rendered “but I stay silly” or “but we stay silly” has since entered popular Gen-Z parlance, usually after expressing some negative thing, often in a state of powerlessness.
Which is an important life skill if powerlessness is something that is often likely.
It’s important for many Gen-Zs with negligible life prospects economically; it’s equally important for 60-somethings getting cancer diagnoses (statistically the most likely decade to find out one has cancer, by the way), and many other kinds of people younger, older, and in between.
Because at the end of the day, we all start powerless and we all end powerless.
Learned helplessness (two kinds)
In psychology, “learned helplessness” occurs when a person or creature gives up after learning that all and any attempts to resist a Bad Thing™ fail, perhaps even badly. A lab rat may just shut down and sit there getting electroshocked, for example. A person subjected to abuse may stop trying to improve their situation, and just go with the path of least resistance.
But, there’s another kind, wherein someone in a position of absolute powerlessness not only makes their peace with that, but also, decides that the one thing the outside world can’t control, is how they take it. Like the hacker we mentioned earlier.
Sometimes the gallows humor is even more literal, laughing at one’s own impending death. Not as a matter of bravado, but genuinely seeing the funny side.
But how?
Unfortunately, fortunately
The trick here is to “find a silver lining” that is nowhere near enough to compensate for the bad thing—and it may even be worse! But that’s fine:
“Unfortunately, I didn’t have time to do the dishes before leaving for my vacation. Fortunately, I also forgot to turn the oven off, so the house burning down covered up my messy kitchen”
Writer’s personal less drastic example: today I set my espresso machine to press me an espresso; it doesn’t have an auto-off and I got distracted and it overflowed everywhere; my immediate reaction was “Oh! I have been blessed with an abundance of coffee!”
This kind of silly little thing, on a daily basis, builds a very solid habit for life that allows one to see the funny side in even the most absurd situations, even matters of life and death (can confirm: been there enough times personally—so far so good, still alive to find the remembered absurdity silly).
The point is not to genuinely value the “silver lining”, because half the time it isn’t even one, really, and it is useless to pretend, in seriousness.
But to pretend in silliness? Now we’re onto something, and the real benefit is in the laughs we had along the way.
Because those worst moments? Are probably when we need it the most, so it’s good to get some practice in!
Want more ways to find the funny and make it a life habit?
We reviewed a good book recently:
The Humor Habit: Rewire Your Brain To Stress Less, Laugh More, And Achieve More’er – by Paul Osincup
Stay silly!

Savoy Cabbage vs Pak Choi – 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 savoy cabbage to pak choi, we picked the savoy.
Why?
Looking at the macros first, the savoy has a little more protein, just under 3x the carbs, and just over 3x the fiber. A modest yet respectable win for savoy.
In terms of vitamins, savoy has more of vitamins B1, B5, B9, E, K, and choline, while pak choi has more of vitamins A, B2, B3, and C. Thus, a 6:4 win for savoy.
When it comes to minerals, savoy has more copper, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while pak choi has more calcium, iron, and potassium. So this time, a 7:3 win for savoy.
On the other hand, pak choi scores higher on the polyphenols side, especially in the categories of kaempferol and quercetin.
Still, adding up the sections, we conclude this one’s an overall win for savoy cabbage. Of course, enjoy either or both, though!

What does it mean to be transgender?
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.
Transgender media coverage has surged in recent years for a wide range of reasons. While there are more transgender television characters than ever before, hundreds of bills are targeting transgender people’s access to medical care, sports teams, gender-specific public spaces, and other institutions.
Despite the increase in conversation about the transgender community, public confusion around transgender identity remains.
Read on to learn more about what it means to be transgender and understand challenges transgender people may face.
What does it mean to be transgender?
Transgender—or “trans”—is an umbrella term for people whose gender identity or gender expression does not conform to their sex assigned at birth. People can discover they are trans at any age.
Gender identity refers to a person’s inner sense of being a woman, a man, neither, both, or something else entirely. Trans people who don’t feel like women or men might describe themselves as nonbinary, agender, genderqueer, or two-spirit, among other terms.
Gender expression describes the way a person communicates their gender through their appearance—such as their clothing or hairstyle—and behavior.
A person whose gender expression doesn’t conform to the expectations of their assigned sex may not identify as trans. The only way to know for sure if someone is trans is if they tell you.
Cisgender—or “cis”—describes people whose gender identities match the sex they were assigned at birth.
How long have transgender people existed?
Being trans isn’t new. Although the word “transgender” only dates back to the 1960s, people whose identities defy traditional gender expectations have existed across cultures throughout recorded history.
How many people are transgender?
A 2022 Williams Institute study estimates that 1.6 million people over the age of 13 identify as transgender in the United States.
Is being transgender a mental health condition?
No. Conveying and communicating about your gender in a way that feels authentic to you is a normal and necessary part of self-expression.
Social and legal stigma, bullying, discrimination, harassment, negative media messages, and barriers to gender-affirming medical care can cause psychological distress for trans people. This is especially true for trans people of color, who face significantly higher rates of violence, poverty, housing instability, and incarceration—but trans identity itself is not a mental health condition.
What is gender dysphoria?
Gender dysphoria describes a feeling of unease that some trans people experience when their perceived gender doesn’t match their gender identity, or their internal sense of gender. A 2021 study of trans adults pursuing gender-affirming medical care found that most participants started experiencing gender dysphoria by the time they were 7.
When trans people don’t receive the support they need to manage gender dysphoria, they may experience depression, anxiety, social isolation, suicidal ideation, substance use disorder, eating disorders, and self-injury.
How do trans people manage gender dysphoria?
Every trans person’s experience with gender dysphoria is unique. Some trans people may alleviate dysphoria by wearing gender-affirming clothing or by asking others to refer to them by a new name and use pronouns that accurately reflect their gender identity. The 2022 U.S. Trans Survey found that nearly all trans participants who lived as a different gender than the sex they were assigned at birth reported that they were more satisfied with their lives.
Some trans people may also manage dysphoria by pursuing medical transition, which may involve taking hormones and getting gender-affirming surgery.
Access to gender-affirming medical care has been shown to reduce the risk of depression and suicide among trans youth and adults.
To learn more about the trans community, visit resources from the National Center for Transgender Equality, the Trevor Project, PFLAG, and Planned Parenthood.
If you or anyone you know is considering suicide or self-harm or is anxious, depressed, upset, or needs to talk, call the Suicide & Crisis Lifeline at 988 or text the Crisis Text Line at 741-741. For international resources, here is a good place to begin.

Ice Cream vs Fruit Sorbet – 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 ice cream to fruit sorbet, we picked the ice cream.
Why?
Well, neither are great!
But the deciding factor is simple: ice cream has more nutrients to go with its sugar.
While “fruit is good” is a very reliable truism in and of itself, sorbet tends to be made with fruit juice (or at best, purée, which for these purposes is more or less the same) and sugar. The small vitamin content is nowhere near enough to make up for this. The fiber having been removed by juicing or puréeing, the fruit juice with added sugar is basically shooting glucose and fructose into your veins while doing little else.
Fruit juice (even freshly-pressed) is nowhere near in the same league of healthiness as actual fruit!
See also: Which Sugars Are Healthier, And Which Are Just The Same?
Ice cream, meanwhile, is also not exactly a health food. But it has at least some minerals worth speaking of (mostly: calcium, potassium, phosphorus), and some fat that a) can be used b) helps slightly slow the absorption of the sugars.
In short: please do not consider either of these things to be a health food. But if you’re going to choose one or the other (and are not lactose-intolerant), then ice cream has some small positives to go with its negatives.
Take care!

Make Time – by Jake Knapp and John Zeratzky
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 live in an information-saturated world, and we have done for so long now that it’s easy to forget: we did not evolve for this!
It’s easy to say “unplug”, but the reality is:
We also have to actually function in this fast-paced info-dense world whether we want to or not, and we are expected to be able to handle it.
So… How?
Appropriately enough, authors Knapp and Zeratsky present the answer in a skimmer-friendly fashion, with summaries and bullet points and diagrams and emboldened text forease of speed-reading. Who uses such tricks?!
In short, less living life in “default mode scramble” and more about making an impact in the ways you actually want to, for you.
