And no, it doesn’t have to be a second language, although that helps a lot:
An Underrated Tool Against Alzheimer’s ← you don’t even have to learn the second language to a high level, to benefit
Rather, what we’re talking about today is your first language fluency. So, for most of our readers, English. For the study participants it was German, because this was a German research team using data from the German population.
The Berlin Aging Study
Previous research has linked intelligence to longevity, but intelligence comprises multiple traits. So, what’s most important? Memory? General intelligence? Nope. Language fluency!
Let’s clarify something before we continue: “fluency” does not, in linguistics, mean what most people use it to mean. It’s not about the size of one’s overall knowledge of the language (e.g. vocabulary size), but rather, it is about one’s ability to speak and/or write fluently—literally, fluently means “flowingly”, i.e. without undue hesitation or difficulty.
The study used data from the Berlin Aging Study, which tracked 516 people aged 70–105 from 1989 onwards.
Researchers assessed four cognitive abilities, with two kinds of tests for each of:
- Verbal fluency (detailed description below)
- Perceptual speed (pattern-recognition speed)
- Verbal knowledge (vocabulary size)
- Episodic memory (personal memory recall)
General intelligence, meanwhile, was assessed as “the average of those 8 scores”.
The two tests for the cognitive ability of “verbal fluency” were:
Categories
Participants had to name as many different animals as possible within 90 seconds. Their answers were subsequently rated for correctness by two independent research assistants, to assure that noticed or unnoticed repetitions, wrong categories, and morphological variants were not coded as correct.
Word beginnings
Participants were asked to name as many different real words starting with the letter s as possible within 90 seconds. The named words were rated for correctness by two independent research assistants to avoid considering repetitions, morphological variants, and wrong words as correct.
You can read about these and the other tests for the other cognitive abilities, in the paper itself:
Verbal Fluency Selectively Predicts Survival in Old and Very Old Age ← if you’re looking for the test descriptions, scroll to “Method” and then scroll past the table, and you’ll see the test descriptions
They found that of all these metrics, only the two verbal fluency tests (and none of the other tests) showed a significant link to longevity.
Why this is important
Although the study does not prove causality (it could be that people who are predisposed to live longer for other reasons are more verbally fluent because of some common factor that influences both language fluency and longevity), it seems as good a reason as any to develop and maintain language fluency.
This builds on what was found in “The Nun Study“, that followed a convent of nuns (because they are a very homogenous sample in terms of occupation, location, diet, routine, etc, so a lot of confounding factors were already controlled-for) and made numerous major discoveries about things that impact aging (including the relevance of the APOE4 gene! That was The Nun Study).
When it came to nuns and language…
Based on the autobiographies written by the nuns in their youth upon taking their vows, there were two factors that were later correlated with not getting dementia:
- Longer sentences
- Positive outlook
- “Idea density”
That latter item means the relative linguistic density of ideas and complexity thereof, and the fluency and vivacity with which they were expressed (this was not a wishy-washy assessment; there was a hard-science analysis to determine numbers).

Sleep Smarter – by Shawn Stevenson
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.
You probably know to avoid blue light before bed, put a curfew on the caffeine, and have fresh bedding. So, what does this book offer that’s new?
As the subtitle suggests, it’s 21 tips for better sleep, so if even half of them are new, then it’ll still be adding value.
This is a book review, not a book summary, but to give an idea of the kind of thing you might not already know: there’s a section on bedroom houseplants! For example…
- Which plants filter the air best according to NASA, rather than “according to tradition”
- Which plants will thrive in what will hopefully be a cool dark environment
- Which plants produce oxygen even at night, rather than just during the day
The writing style is personable without losing clarity or objectivity:
- We read personal anecdotes, and we read science
- We get “I tried this”, and we get “this sleep study found such-and-such”
- We get not just the “what”, but also the “why” and the “how”
We get the little changes that make a big difference—sometimes the difference between something working or not!
Bottom line: if you’d like to get better sleep and a blue light filter hasn’t wowed you and changed your life, this book will bring your sleep knowledge (and practice) to the next level.

Who you are and where you live shouldn’t determine your ability to survive cancer
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.
In Canada, nearly everyone has a cancer story to share. It affects one in every two people, and despite improvements in cancer survivorship, one out of every four people affected by cancer still will die from it.
As a scientist dedicated to cancer care, I work directly with patients to reimagine a system that was never designed for them in the first place – a system in which your quality of care depends on social drivers like your appearance, your bank statements and your postal code.
We know that poverty, poor nutrition, housing instability and limited access to education and employment can contribute to both the development and progression of cancer. Quality nutrition and regular exercise reduce cancer risk but are contingent on affordable food options and the ability to stay active in safe, walkable neighbourhoods. Environmental hazards like air pollution and toxic waste elevate the risk of specific cancers, but are contingent on the built environment, laws safeguarding workers and the availability of affordable housing.
On a health-system level, we face implicit biases among care providers, a lack of health workforce competence in addressing the social determinants of health, and services that do not cater to the needs of marginalized individuals.
Indigenous peoples, racialized communities, those with low income and gender diverse individuals face the most discrimination in health care, resulting in inadequate experiences, missed diagnosis and avoidance of care. One patient living in subsidized housing told me, “You get treated like a piece of garbage – you come out and feel twice as bad.”
As Canadians, we benefit from a taxpayer funded health-care system that encompasses cancer care services. The average Canadian enjoys a life expectancy of more than 80 years and Canada boasts high cancer survival rates. While we have made incredible strides in cancer care, we must work together to ensure these benefits are equally shared amongst all people in Canada. We need to redesign systems of care so that they are:
- Anti-oppressive. We must begin by understanding and responding to historical and systemic racism that shapes cancer risk, access to care and quality of life for individuals facing marginalizing conditions. Without tackling the root causes, we will never be able to fully close the cancer care gap. This commitment involves undoing intergenerational trauma and harm through public policies that elevate the living and working conditions of all people.
- Patient-centric. We need to prioritize patient needs, preferences and values in all aspects of their health-care experience. This means tailoring treatments and services to individual patient needs. In policymaking, it involves creating policies that are informed by and responsive to the real-life experiences of patients. In research, it involves engaging patients in the research process and ensuring studies are relevant to and respectful of their unique perspectives and needs. This holistic approach ensures that patients’ perspectives are central to all aspects of health care.
- Socially just. We must strive for a society in which everyone has equal access to resources, opportunities and rights, and systemic inequalities and injustices are actively challenged and addressed. When redesigning the cancer care system, this involves proactive practices that create opportunities for all people, particularly those experiencing the most marginalization, to become involved in systemic health-care decision-making. A system that is responsive to the needs of the most marginalized will ultimately work better for all people.
Who you are, how you look, where you live and how much money you make should never be the difference between life and death. Let us commit to a future in which all people have the resources and support to prevent and treat cancer so that no one is left behind.

Starfruit vs Soursop – 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 starfruit to soursop, we picked the soursop.
Why?
First, by starfruit, we also mean carambola, which is a different name for the same fruit, and by soursop we also mean graviola/guyabano/guanábana, which are different namers for the same fruit. Now, as for their health qualities:
In terms of macros, the soursop has more carbs and fiber, the ratio of which also give it the lower glycemic index. So, a win for soursop here.
When it comes to vitamins, starfruit has more of vitamins A, B5, C, and E, while soursop has more of vitamins B1, B2, B3, B6, B7, B9, and K. Another win for soursop.
In the category of minerals, starfruit has slightly more copper, manganese, and zinc, while soursop has much more calcium, iron, magnesium, phosphorus, and potassium. One more win for soursop!
Adding up the sections makes for a clear and overwhelming win for soursop, but let’s address to quick safety considerations while we’re here:
- Soursop extract has been claimed to be an effective cancer treatment. It isn’t. There is no evidence for this at all; just one unscrupulous company that spread the claims.
- Soursop contains annonacin, a neurotoxin. That sounds scary, but much like with apple seeds and cyanide, the quantities you’d have to consume to suffer ill effects are absurd. Remember how capsaicin (as found in hot peppers) is also a neurotoxin, too and has many health benefits. Humans have a long and happy tradition of enjoying things that are toxic at high doses, but in small doses are neutral or even beneficial. Pretty much all things we can consume (including oxygen, and water) are toxic at sufficient doses.
In short, both of these fruits are fine and good, neither will treat cancer, but both will help to keep you in good health. As for nutritional density, the soursop wins in every category.

Top 8 Fruits That Prevent & Kill Cancer ← soursop has no special cancer treatment properties, but actual evidence shows these fruits are beneficial (being good as a preventative, and also definitely a worthy adjunct to—but not a replacement for—mainstream anticancer therapies if you have cancer).
Take care!

Feminist narratives are being hijacked to market medical tests not backed by evidence
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.
Corporations have used feminist language to promote their products for decades. In the 1980s, companies co-opted messaging about female autonomy to encourage women’s consumption of unhealthy commodities, such as tobacco and alcohol.
Today, feminist narratives around empowerment and women’s rights are being co-opted to market interventions that are not backed by evidence across many areas of women’s health. This includes by commercial companies, industry, mass media and well-intentioned advocacy groups.
Some of these health technologies, tests and treatments are useful in certain situations and can be very beneficial to some women.
However, promoting them to a large group of asymptomatic healthy women that are unlikely to benefit, or without being transparent about the limitations, runs the risk of causing more harm than good. This includes inappropriate medicalisation, overdiagnosis and overtreatment.
In our analysis published today in the BMJ, we examine this phenomenon in two current examples: the anti-mullerian hormone (AMH) test and breast density notification.
The AMH test
The AMH test is a blood test associated with the number of eggs in a woman’s ovaries and is sometimes referred to as the “egg timer” test.
Although often used in fertility treatment, the AMH test cannot reliably predict the likelihood of pregnancy, timing to pregnancy or specific age of menopause. The American College of Obstetricians and Gynaecologists therefore strongly discourages testing for women not seeking fertility treatment.
The AMH test can’t predict your chance of getting pregnant.
Anastasia Vityukova/UnsplashDespite this, several fertility clinics and online companies market the AMH test to women not even trying to get pregnant. Some use feminist rhetoric promising empowerment, selling the test as a way to gain personalised insights into your fertility. For example, “you deserve to know your reproductive potential”, “be proactive about your fertility” and “knowing your numbers will empower you to make the best decisions when family planning”.
The use of feminist marketing makes these companies appear socially progressive and champions of female health. But they are selling a test that has no proven benefit outside of IVF and cannot inform women about their current or future fertility.
Our recent study found around 30% of women having an AMH test in Australia may be having it for these reasons.
Misleading women to believe that the test can reliably predict fertility can create a false sense of security about delaying pregnancy. It can also create unnecessary anxiety, pressure to freeze eggs, conceive earlier than desired, or start fertility treatment when it may not be needed.
While some companies mention the test’s limitations if you read on, they are glossed over and contradicted by the calls to be proactive and messages of empowerment.
Breast density notification
Breast density is one of several independent risk factors for breast cancer. It’s also harder to see cancer on a mammogram image of breasts with high amounts of dense tissue than breasts with a greater proportion of fatty tissue.
While estimates vary, approximately 25–50% of women in the breast screening population have dense breasts.
Dense breasts can make it harder to detect cancer.
Tyler Olsen/ShutterstockStemming from valid concerns about the increased risk of cancer, advocacy efforts have used feminist language around women’s right to know such as “women need to know the truth” and “women can handle the truth” to argue for widespread breast density notification.
However, this simplistic messaging overlooks that this is a complex issue and that more data is still needed on whether the benefits of notifying and providing additional screening or tests to women with dense breasts outweigh the harms.
Additional tests (ultrasound or MRI) are now being recommended for women with dense breasts as they have the ability to detect more cancer. Yet, there is no or little mention of the lack of robust evidence showing that it prevents breast cancer deaths. These extra tests also have out-of-pocket costs and high rates of false-positive results.
Large international advocacy groups are also sponsored by companies that will financially benefit from women being notified.
While stronger patient autonomy is vital, campaigning for breast density notification without stating the limitations or unclear evidence of benefit may go against the empowerment being sought.
Ensuring feminism isn’t hijacked
Increased awareness and advocacy in women’s health are key to overcoming sex inequalities in health care.
But we need to ensure the goals of feminist health advocacy aren’t undermined through commercially driven use of feminist language pushing care that isn’t based on evidence. This includes more transparency about the risks and uncertainties of health technologies, tests and treatments and greater scrutiny of conflicts of interests.
Health professionals and governments must also ensure that easily understood, balanced information based on high quality scientific evidence is available. This will enable women to make more informed decisions about their health.

What should I do if I can’t see a psychiatrist?
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.
People presenting at emergency with mental health concerns are experiencing the longest wait times in Australia for admission to a ward, according to a new report from the Australasian College of Emergency Medicine.
But with half of New South Wales’ public psychiatrists set to resign next week after ongoing pay disputes – and amid national shortages in the mental health workforce – Australians who rely on psychiatry support may be wondering where else to go.
If you can’t get in to see a psychiatrist and you need help, there are some other options. However in an emergency, you should call 000.
Why do people see a psychiatrist?
Psychiatrists are doctors who specialise in mental health and can prescribe medication.
People seek or require psychiatry support for many reasons. These may include:
- severe depression, including suicidal thoughts or behaviours
- severe anxiety, panic attacks or phobias
- post-traumatic stress disorder (PTSD)
- eating disorders, such as anorexia or bulimia
- attention deficit hyperactivity disorder (ADHD).
Psychiatrists complement other mental health clinicians by prescribing certain medications and making decisions about hospital admission. But when psychiatry support is not available a range of team members can contribute to a person’s mental health care.
Can my GP help?
Depending on your mental health concerns, your GP may be able to offer alternatives while you await formal psychiatry care.
GPs provide support for a range of mental health concerns, regardless of formal diagnosis. They can help address the causes and impact of issues including mental distress, changes in sleep, thinking, mood or behaviour.
The GP Psychiatry Support Line also provides doctors advice on care, prescription medication and how support can work.
It’s a good idea to book a long consult and consider taking a trusted person. Be explicit about how you’ve been feeling and what previous supports or medication you’ve accessed.
What about psychologists, counsellors or community services?
Your GP should also be aware of supports available locally and online.
For example, Head to Health is a government initiative, including information, a nationwide phone line, and in-person clinics in Victoria. It aims to improve mental health advice, assessment and access to treatment.
Medicare Mental Health Centres provide in-person care and are expanding across Australia.
There are also virtual care services in some areas. This includes advice on individualised assessment including whether to go to hospital.
Some community groups are led by peers rather than clinicians, such as Alternatives to Suicide.
How about if I’m rural or regional?
Accessing support in rural or regional areas is particularly tough.
Beyond helplines and formal supports, other options include local Suicide Prevention Networks and community initiatives such as ifarmwell and Men’s sheds.
Should I go to emergency?
As the new report shows, people who present at hospital emergency departments for mental health should expect long wait times before being admitted to a ward.
But going to a hospital emergency department will be essential for some who are experiencing a physical or mental health crisis.
Managing suicide-related distress
With the mass resignation of NSW psychiatrists looming, and amid shortages and blown-out emergency waiting times, people in suicide-related distress must receive the best available care and support.
Roughly nine Australians die by suicide each day. One in six have had thoughts of suicide at some point in their lives.
Suicidal thoughts can pass. There are evidence-based strategies people can immediately turn to when distressed and in need of ongoing care.
Safety planning is a popular suicide prevention strategy to help you stay safe.
What is a safety plan?
This is a personalised, step-by-step plan to remain safe during the onset or worsening of suicidal urges.
You can develop a safety plan collaboratively with a clinician and/or peer worker, or with loved ones. You can also make one on your own – many people like to use the Beyond Now app.
Safety plans usually include:
- recognising personal warning signs of a crisis (for example, feeling like a burden)
- identifying and using internal coping strategies (such as distracting yourself by listening to favourite music)
- seeking social supports for distraction (for example, visiting your local library)
- letting trusted family or friends know how you’re feeling – ideally, they should know they’re in your safety plan
- knowing contact details of specific mental health services (your GP, mental health supports, local hospital)
- making the environment safer by removing or limiting access to lethal means
- identifying specific and personalised reasons for living.
Our research shows safety planning is linked to reduced suicidal thoughts and behaviour, as well as feelings of depression and hopelessness, among adults.
Evidence from people with lived experience shows safety planning helps people to understand their warning signs and practice coping strategies.
Sharing your safety plan with loved ones may help understand warning signs of a crisis. Dragana Gordic/Shutterstock Are there helplines I can call?
There are people ready to listen, by phone or online chat, Australia-wide. You can try any of the following (most are available 24 hours a day, seven days a week):
Suicide helplines:
- Lifeline 13 11 14
- Suicide Call Back Service 1300 659 467
There is also specialised support:
- for men: MensLine Australia 1300 78 99 78
- children and young people: Kids’ Helpline 1800 55 1800
- Aboriginal and Torres Strait Islander people: 13YARN 13 92 76
- veterans and their families: Open Arms 1800 011 046
- LGBTQIA+ community: QLife 1300 184 527
- new and expecting parents: PANDA 1300 726 306
- people experiencing eating disorders: Butterfly Foundation 1800 33 4673.
Additionally, each state and territory will have its own list of mental health resources.
With uncertain access to services, it’s helpful to remember that there are people who care. You don’t have to go it alone.

The Comfort Book – by Matt Haig
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 what it says on the tin”. Matt Haig, bestselling author of “Reasons to Stay Alive” (amongst other works) is here with “a hug in a book”.
The format of the book is an “open it at any page and you’ll find something of value” book. Its small chapters are sometimes a few pages long, but often just a page. Sometimes just a line. Always deep.
All of us, who live long enough, will ponder our mortality sometimes. The feelings we may have might vary on a range from “afraid of dying” to “despairing of living”… but Haig’s single biggest message is that life is full of wonder; each moment precious.
- That hope is an incredible (and renewable!) resource.
- That we are more than a bad week, or month, or year, or decade.
- That when things are taken from us, the things that remain have more value.
Bottom line: you might cry (this reviewer did!), but it’ll make your life the richer for it, and remind you—if ever you need it—the value of your amazing life.
