6 Ways To Look After Your Back
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.
Back To Back
When people think about looking after their back, often thought does not go much further than sitting with good posture, and perhaps even standing with good posture. And those things are important, but:
1) People’s efforts to have good posture often result in overcorrecting creating an anterior pelvic tilt that causes lower back problems.
Quick tip: if you’re sticking your butt out, you’re doing it wrong (no matter how great your butt is). Instead, to find the correct posture, go up on your tip-toes for a moment, then imagine a plumb-line down the center of your body, thus perpendicular to the floor, going all the way down to the ground. Now, slowly return your heels to the ground, but as you do so, keep your spine aligned to the plumb-line, so you’re not moving backwards as you drop, just directly down. This will land you in perfect posture.
Unless you have scoliosis. In which case, it’ll get you as close to good posture as is likely attainable from any quick tip.
2) There’s a lot more to looking after our back than just good posture!
Here are 5 other important things to do:
Be strong
Do strength-training for your back. How to do that is beyond the scope of today’s feature, but there are many good guides and also personal trainers that can be found.
Start off easy and work up, but do start. The stronger your back is, the less likely a momentary lapse in concentration is to throw out your back because you picked something up with imperfect form.

Stretch intentionally
Many back injuries occur as a result of stretching and/or twisting awkwardly, so if you ensure your basic mobility and range of motion is good, the less likely it is that unthinkingly twisting around 270° to see where that wasp was going will slip a disk.
The more you stretch intentionally (carefully, please), the more you will be able to stretch unintentionally without injury.

Stand when you can, walk when you can
We humans have outrun our evolution in a lot of ways, and/but one thing our bodies are definitely not well-adapted for is sitting. Unless we are sitting in a low squat the way you might often see an orang-utan sitting, sitting is not a good way of being for us. Even sitting seiza-style or cross-legged is passable for a short while, not for too long.
So, while there sure are times we need to sit (especially if you’re driving!) minimizing those times is ideal. There are a lot of activities that are traditionally done sitting, where there’s no need for it to be so. For example, your writer here sits for the day’s main meal, but takes any smaller meal standing (and when guests visit for a coffee or such, I’ll offer them the couch while I myself prop up the fireplace). Standing desks are also great if you spend a lot of time at the computer for any reason.

Rest when you need to
You can’t stand all the time! But know this: if you want to rest your legs, lying down is a lot better for your back (and internal organs) than sitting.
Taking a 5 minute break lying on your couch, or bed, or floor, is a perfectly good option and only social convention says otherwise.
If you want a compromise option, though? A recliner chair, in the reclined position, is a better for your back than being scrunched up in the Economy Class Flight position.
PS: About that bed situation…
What Mattress Is Best, By Science?
Kill pain before it kills you
Painkillers aren’t great for the health per se, but pain (or rather, our bodily responses to such) can be worse. Half the time, when it comes to musculoskeletal problems, things get a lot worse a lot more quickly because of how we overcompensate due to the pain. So, take your pain seriously, and remember, the right amount of pain is zero.

Why Do We Have Pores, And Could We Not?

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
❝Do we really need pores, and why are they bigger on the face?❞
Pores secrete sweat or sebum (there are different kinds of pores for each).
If we didn’t have sweat pores, we’d be unable to sweat, which superficially may seem like a bonus, but it’d make us prone to overheating (like dogs, pigs, and other mammals that cannot sweat).
If we didn’t have sebum pores (usually called hair follicles, which are supplied by a sebaceous gland), we’d be completely hairless, and also unable to supply our skin with natural oils that keep it healthy. So we’d have no hair and very unhappy skin.
Which is ironic, because to believe beauty magazines, we must at all costs minimize our pores (and indeed, interventions like botox* can kill them).
*Let’s give that its full name though:
Suffice it to say, we do not recommend getting injected with neurotoxins unless it is truly necessary to ward off a greater harm.
As for being bigger on the face, they need not be, but sebaceous glands are more active and numerous there, being most active and numerous in the face/forehead—which is why oily skin is more likely to appear there than other parts of the body.
If your facial sebaceous glands are too active for your liking…
…there are ways to reduce that, a simple and relatively gentle way (relative, for example, botox) is with retinoids, including retinols or retinoic acids. Here’s some of the science of that; the paper is about treating acne, but the mechanism of action is the same (down-regulating the sebaceous glands’ action):
The potential side-effects, however were noted as:
- Cheilitis
- Desquamation of the skin
- Pruritus
Which, in translation from sciencese, means:
- Chapped lips
- Flaky skin
- Itchiness
Which aren’t necessarily fun, which is why with retinoids are best taken in very small doses at first to see how your skin reacts.
Remember when we said what your skin would be like without pores? This is what would happen, only much worse.
Take care!

Younger Next Year – by Chris Crowley & Dr. Henry Lodge
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.
Is it diet and exercise? Well, of course that’s a component. Specific kinds of exercise, too. But, as usual when we feature a book, there’s more:
In this case, strong throughout is the notion of life being a marathon not a sprint—and training for it accordingly.
Doing the things now that you’ll really wish you’d started doing sooner, and finding ways to build them into daily life.
Not just that, though! The authors take a holistic approach to life and health, and thus also cover work life, social life, and so forth. Now, you may be thinking “I’m already in the 80 and beyond category; I don’t work” and well, the authors advise that you do indeed work. You don’t have to revamp your career, but science strongly suggests that people who work longer, live longer.
Of course that doesn’t have to mean going full-throttle like a 20-year-old determined to make their mark on the world (you can if you want, though). It could be volunteering for a charity, or otherwise just finding a socially-engaging “work-like” activity that gives you purpose.
About the blend of motivational pep talk and science—this book is heavily weighted towards the former. It has, however, enough science to keep it on the right track throughout. Hence the two authors! Crowley for motivational pep, and Dr. Lodge for the science (with extra input from brain surgeon Dr. Hamilton, too).
Bottom line: if you want to feel the most prepared possible for the coming years and decades, this is a great book that covers a lot of bases.

This Naked Mind – by Annie Grace
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 all read about the many, many, dangers of drinking. We’ve also probably all read about how to make the change to not drinking. Put things out of sight, tell your friends, have this rule, have this excuse (for not drinking) ready to give to people who challenge you, consider a support group, and so on.
What Annie Grace offers in this #1 bestseller is different:
A blend of mostly psychology and sociology, to examine the “liminal thinking” stages that funnel us to drink in the first place… and where that leads, and how to clamber back out of the pitcher plant we weren’t necessarily aware we were sliding into.
While she kicks off citing Jung, from a psychological perspective more of this book is CBTish, as it pertains a lot to examining the process of:
- belief—held and defended, based on the…
- conclusion—drawn, often irrationally, from the…
- experience—that we had upon acting on an…
- observation—often mistaking an illusion for the underlying…
- reality
…and how we can and often do go wrong at each step, and how little of the previous steps we can perceive at any given time.
What does this mean for managing/treating alcoholism or a tendency towards alchoholism?
It means interrupting those processes in a careful, surgically precise fashion, so that suddenly… The thing has no more power over us.
Whether you or a loved one struggle with a tendency to addiction (any addiction, actually, the advice goes the same), or are just curious about the wider factors at hand in the epidemiology of addiction, this book is for you.

The Blue Zones, Second Edition – by Dan Buettner
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.
Eat beans & greens, take walks, have a purpose; you can probably list off the top of your head some of the “advices from Blue Zones”, so what makes this book stand out?
This is perhaps one of the most thoughtful investigations; the author (a National Geographic researcher) toured and researched all the Blue Zones, took many many notes (we get details), and asked a lot of questions that others skipped.
For example, a lot of books about the Blue Zones mention the importance of community—but they don’t go into much detail of what that looks like… And they certainly don’t tend to explain what we should do about it.
And that’s because community is often viewed as environmental in a way that we can’t control. If we want to take supplements, eat a certain way, exercise, etc, we can do all those things alone if we want. But if we want community? We’re reliant on other people—and that’s a taboo in the US, and US-influenced places.
So, one way this book excels is in describing how exactly people foster community in the Blue Zones (hint: the big picture—the form of the community—is different in each place, but the individual actions taken are similar), with particular attention to the roles actively taken on by the community elders.
In a similar vein, “reduce stress” is good, but what mindsets and mechanisms do they use that are still reproducible if we are not, for example, Okinawan farmers? Again, Buettner delivers in spades.
Bottom line: this is the Blue Zones book that digs deeper than others, and makes the advices much more applicable no matter where we live.

Genital herpes is on the rise. Here’s what to know about this common infection
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 World Health Organization (WHO) recently released new estimates suggesting around 846 million people aged between 15 and 49 live with a genital herpes infection.
That’s equivalent to one in every five people from that age group.
At least one person each second (42 million people annually) contracts a new genital herpes infection.
So what is genital herpes, and are cases on the rise? Here’s what to know about this common infection.
Peakstock/Shutterstock First, what causes genital herpes?
Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus, which also causes cold sores.
There are two types of herpes simplex virus, HSV-1 and HSV-2 (and it’s possible to be infected by both at the same time).
HSV-1 most commonly spreads through oral contact such as kissing or sharing infected objects such as lip balm, cups or utensils, and presents as cold sores (or oral herpes) around the mouth. But it can also be sexually transmitted to cause a genital herpes infection.
An estimated 3.8 billion people under the age of 50 (64%) globally have HSV-1.
HSV-2 is less prevalent, but almost always causes a genital herpes infection. Some 520 million people aged 15–49 (13%) worldwide are believed to have HSV-2.
The initial episode of genital herpes can be quite painful, with blisters, ulcers and peeling skin around the genitals over 7–10 days.
Not all people have severe (or any) initial symptoms. This means a person might not know they have been infected with a herpes virus.
Herpes is a lifelong infection, which means once you contract the virus, you have it forever. After an initial episode, subsequent episodes can occur, but are usually less painful or even symptom free.
Both oral and genital herpes are particularly easy to spread when you have active lesions (cold sores or genital ulcers). But even with no symptoms, herpes can still be spread to a partner.
And although relatively rare, oral herpes can be transmitted to the genital area, and genital herpes can be transmitted to the mouth through oral sex.
If an expectant mother exhibits a genital herpes infection close to childbirth, there are risks to the baby. A herpes infection can be very serious in a baby, and the younger the infant, the more vulnerable they are. This is also one reason why you should avoid kissing a baby on the mouth.
Changing trends
WHO’s recent figures brought together data from around the world to estimate the prevalence of genital herpes in 2020, compared with previous estimates in 2012 and 2016.
This data shows no significant difference in the prevalence of genital herpes caused by HSV-2 since 2016, but does highlight increases in genital herpes infections caused by HSV-1.
The estimated number of genital HSV-1 infections globally was nearly twice as high in 2020 compared with 2016 (376 million compared with 192 million).
A 2022 study looking at Australia, New Zealand and Canada found more than 60% of genital herpes infections are still caused by HSV-2. But this is declining by about 2% each year while new genital infections that result from HSV-1 are rising.
Genital herpes can be quite painful, presenting as sores and lesions that in severe cases, may take up to a month to fully heal. Christian Moro There’s no simple fix, but safe sex is important
Genital herpes causes a substantial disease burden and economic cost to health-care services.
With such a large proportion of the world’s population infected with HSV-1, evidence this virus is increasingly causing genital herpes is concerning.
There’s no cure for genital herpes, but some medications, such as antivirals, can help reduce the amount of virus present in the system. While this won’t kill it completely, it helps to prevent symptomatic genital herpes recurrences, improve quality of life, and minimise the risk of transmission.
To prevent the spread of genital herpes and other STIs, practise safe sex, particularly if you’re not sure of your partner’s sexual health. You need to use a barrier method such as condoms to protect against STIs (a contraceptive such as the pill won’t work). This includes during oral sex.
As herpes is now so common, testing is not usually included as part of a regular sexual health check-up, except for in specific circumstances such as during pregnancy or severe episodes.
So it’s wise not to let your guard down, even if your partner insists they have received the all-clear from a recent check-up.
If there are herpes lesions present around the genitals, avoid sex entirely. Even condoms are not fully effective at these times, as exposed areas can still transmit the infection.
Practising safe sex can help prevent the spread of herpes. cottonbro studio/Pexels Immune health
If you are infected with HSV-1 or HSV-2 it’s more likely symptoms will appear when you’re stressed, tired or overwhelmed. During these times, our immune system may not be as functional, and dormant viruses such as herpes can start to develop quickly in our bodies.
To reduce the risk of recurrent herpes infections, try to eat healthily, get at least seven hours of sleep each night if possible, and look out for when your body may be telling you to take a step back and relax. This self-care can go a long way towards keeping latent viruses at bay.
While the prevalence has increased significantly in recent years, we have not lost the war on genital herpes just yet. Safe sexual practices, education and awareness can help reduce its spread, and the stigma around it.
If you have personal concerns, you should discuss them with a medical professional.
