This is a little flashier in presentation than we usually go for here, but the content is actually very good. Indeed, we’ve featured Jim Kwik before, with different, but also good content—in that case, physical exercises that strengthen the brain.

This time, Kwik (interspersed with motivational speeches that you may or may not benefit from, but they are there) offers a step-by-step course in improving various metrics of cognitive ability. His methods were produced by trial and error, and now have been refined and enjoyed by man. If it sounds like a sales gimmick, it is a bit, but the good news is that everything you need to benefit is in the book; it’s not about upselling to a course or “advanced” books or whatnot.

The style is enthusiastically conversational, and instructions when given (which is often) are direct and clear.

Bottom line: one of the most critical abilities a brain can have is the ability to improve itself, so whatever level your various cognitive abilities are at right now, if you apply this book, you will almost certainly improve in one or more areas, which will make it worth the price of the book.

  • High-Protein Paneer

    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.

    Paneer (a kind of Desi cheese used in many recipes from that region) is traditionally very high in fat, mostly saturated. Which is delicious, but not exactly the most healthy.

    Today we’ll be making a plant-based paneer that does exactly the same jobs (has a similar texture and gentle flavor, takes on the flavors of dishes in the same way, etc) but with a fraction of the fat (of which only a trace amount is saturated, in this plant-based version), and even more protein. We’ll use this paneer in some recipes in the future, but it can be enjoyed by itself already, so let’s get going…

    You will need

    • ½ cup gram flour (unwhitened chickpea flour)
    • Optional: 1 tsp low-sodium salt

    Method

    (we suggest you read everything at least once before doing anything)

    1) Whisk the flour (and salt, if using) with 2 cups water in a big bowl, whisking until the texture is smooth.

    2) Transfer to a large saucepan on a low-to-medium heat; you want it hot, but not quite a simmer. Keep whisking until the mixture becomes thick like polenta. This should take 10–15 minutes, so consider having someone else to take shifts if the idea of whisking continually for that long isn’t reasonable to you.

    3) Transfer to a non-stick baking tin that will allow you to pour it about ½” deep. If the tin’s too large, you can always use a spatula to push it up against two or three sides, so that it’s the right depth

    3) Refrigerate for at least 10 minutes, but longer is better if you have the time.

    4) When ready to serve/use, cut it into ½” cubes. These can be served/used now, or kept for about a week in the fridge.

    Enjoy!

  • Who Screens The Sunscreens?

    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 Screen The Sunscreens!

    Yesterday, we asked you what your sunscreen policy was, and got a spread of answers. Apparently this one was quite polarizing!

    One subscriber who voted for “Sunscreen is essential to protect us against skin aging and cancer” wrote:

    ❝My mom died of complications from melanoma, so we are vigilant about sun and sunscreen. We are a family of campers and hikers and gardeners—outdoors in all seasons—and we never burn❞

    Our condolences with regard to your mom! Life is so precious, and when something like that happens, it tends to stick with us. We’re glad you and your family are taking care of yourselves.

    Of the subscribers who voted for “I put some on if I think I might otherwise get sunburned”, about half wrote to express uncertainties:

    • uncertainty about how safe it is, and
    • uncertainty about how helpful it is

    …so we’re going to tackle those questions in a moment. But what of those who voted for “Sunscreen is full of harmful chemicals that can cause cancer”?

    Of those, only one wrote a message, which was to say one has to be very careful of what is in the formula.

    Let’s take a look, then…

    Sunscreen is full of harmful chemicals that can cause cancer: True or False?

    False—according to current best science. Research is ongoing!

    There are four main chemicals (found in most sunscreens) that people tend to worry about:

    • Abobenzone
    • Oxybenzone
    • Octocrylene
    • Ecamsule

    Now, these two sound like four brands of rocket fuel, but then, dihydrogen monoxide (DHMO), which is also found in most sunscreens, sounds like a deadly toxin too. That’s water, by the way.

    But what of these four chemicals? Well, as we say, research is ongoing, but we found a study that measured all four, to see how much got into the blood, and what adverse effects, if any, this caused.

    We’ll skip to their conclusion:

    ❝In this preliminary study involving healthy volunteers, application of 4 commercially available sunscreens under maximal use conditions resulted in plasma concentrations that exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens. The systemic absorption of sunscreen ingredients supports the need for further studies to determine the clinical significance of these findings. These results do not indicate that individuals should refrain from the use of sunscreen.❞

    Now, “exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens” sounds alarming, so why did they close with the words “These results do not indicate that individuals should refrain from the use of sunscreen”?

    Let’s skip back up to a line from the results:

    ❝The most common adverse event was rash, which developed in 1 participant with each sunscreen.❞

    This was most probably due to the oxybenzone, which can cause allergic skin reactions in some people.

    Let us take a moment to remember the most common adverse event that occurs from not wearing sunscreen: sunburn!

    You can read the full study here:

    Effect of Sunscreen Application Under Maximal Use Conditions on Plasma Concentration of Sunscreen Active Ingredients—A Randomized Clinical Trial

    None of those ingredients have been found to be carcinogenic, even at the maximal blood plasma concentrations studied, from applications 4x/day to 75% of the body.

    UVA rays, on the other hand, are absolutely very much known to cause cancer, and the effect is cumulative.

    Sunscreen is essential to protect us against skin aging and cancer: True or False?

    True, unequivocally, unless we live indoors and/or otherwise never go about under sunlight.

    “But our ancestors—” lived under the same sun we do, and either used sunscreen or got advanced skin aging and cancer.

    Sunscreen of times past ranged from mud to mineral lotions, but it’s pretty much always existed. Even non-human animals that have skin and don’t have fur or feathers, tend to take mud-baths in sunny parts of the world.

    If you’d like to avoid oxybenzone and other chemicals, though, you might have your reasons. Maybe you’re allergic, or maybe you read that it’s a potential endocrine disruptor with estrogen-like and anti-androgenic properties that you don’t want.

    There are other options, to include physical blockers containing zinc and titanium dioxide, which are generally recognized as safe and effective ingredients.

    If you’re interested, you can even make your own sunscreen that blocks both UVA and UVB rays (UVA is what causes skin cancer; UVB is “milder” and is what causes sunburn):

    So, no question/request too big or small

    First: a correction and expansion!

    After yesterday’s issue of 10almonds covering breast cancer risks and checks, a subscriber wrote to say, with regard to our opening statement, which was:

    Anyone (who has not had a double mastectomy, anyway) can get breast cancer”

    ❝I have been enjoying your newsletter. This statement is misleading and should have a disclaimer that says even someone who has had a double mastectomy can get breast cancer, again. It is true and nothing…nothing is 100% including a mastectomy. I am a 12 year “thriver” (I don’t like to use the term survivor) who has had a double mastectomy. I work with a local hospital to help newly diagnosed patients deal with their cancer diagnosis and the many decisions that follow. A double mastectomy can help keep recurrence from happening but there are no guarantees. I tried to just delete this and let it go but it doesn’t feel right. Thank you!❞

    Thank you for writing in about this! We wouldn’t want to mislead, and we’re always glad to hear from people who have been living with conditions for a long time, as (assuming they are a person inclined to learning) they will generally know topics far more deeply than someone who has researched it for a short period of time.

    Regards a double mastectomy (we’re sure you know this already, but noting here for greater awareness, prompted by your message), a lot of circumstances can vary. For example, how far did a given cancer spread, and especially, did it spread to the lymph nodes at the armpits? And what tissue was (and wasn’t) removed?

    Sometimes a bilateral prophylactic mastectomy will leave the lymph nodes partially or entirely intact, and a cancer could indeed come back, if not every last cancerous cell was removed.

    A total double mastectomy, by definition, should have removed all tissue that could qualify as breast tissue for a breast cancer, including those lymph nodes. However, if the cancer spread unnoticed somewhere else in the body, then again, you’re quite correct, it could come back.

    Some people have a double mastectomy without having got cancer first. Either because of a fear of cancer due to a genetic risk (like Angelina Jolie), or for other reasons (like Elliot Page).

    This makes a difference, because doing it for reasons of cancer risk may mean surgeons remove the lymph nodes too, while if that wasn’t a factor, surgeons will tend to leave them in place.

    In principle, if there is no breast tissue, including lymph nodes, and there was no cancer to spread, then it can be argued that the risk of breast cancer should now be the same “zero” as the risk of getting prostate cancer when one does not have a prostate.

    But… Surgeries are not perfect, and everyone’s anatomy and physiology can differ enough from “textbook standard” that surprises can happen, and there’s almost always a non-zero chance of certain health outcomes.

    For any unfamiliar, here’s a good starting point for learning about the many types of mastectomy, that we didn’t go into in yesterday’s edition. It’s from the UK’s National Health Service:

    NHS: Mastectomy | Types of Mastectomy

    And for the more sciency-inclined, here’s a paper about the recurrence rate of cancer after a prophylactic double mastectomy, after a young cancer was found in one breast.

    The short version is that the measured incidence rate of breast cancer after prophylactic bilateral mastectomy was zero, but the discussion (including notes about the limitations of the study) is well worth reading:

    Breast Cancer after Prophylactic Bilateral Mastectomy in Women with a BRCA1 or BRCA2 Mutation

    ❝[Can you write about] the availability of geriatric doctors Sometimes I feel my primary isn’t really up on my 70 year old health issues. I would love to find a doctor that understands my issues and is able to explain them to me. Ie; my worsening arthritis in regards to food I eat; in regards to meds vs homeopathic solutions.! Thanks!❞

    That’s a great topic, worthy of a main feature! Because in many cases, it’s not just about specialization of skills, but also about empathy, and the gap between studying a condition and living with a condition.

    About arthritis, we’re going to do a main feature specifically on that quite soon, but meanwhile, you might like our previous article:

    As for homeopathy, your question prompts our poll today!

  • How a Friend’s Death Turned Colorado Teens Into Anti-Overdose Activists

    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.

    Gavinn McKinney loved Nike shoes, fireworks, and sushi. He was studying Potawatomi, one of the languages of his Native American heritage. He loved holding his niece and smelling her baby smell. On his 15th birthday, the Durango, Colorado, teen spent a cold December afternoon chopping wood to help neighbors who couldn’t afford to heat their homes.

    McKinney almost made it to his 16th birthday. He died of fentanyl poisoning at a friend’s house in December 2021. His friends say it was the first time he tried hard drugs. The memorial service was so packed people had to stand outside the funeral home.

    Now, his peers are trying to cement their friend’s legacy in state law. They recently testified to state lawmakers in support of a bill they helped write to ensure students can carry naloxone with them at all times without fear of discipline or confiscation. School districts tend to have strict medication policies. Without special permission, Colorado students can’t even carry their own emergency medications, such as an inhaler, and they are not allowed to share them with others.

    “We realized we could actually make a change if we put our hearts to it,” said Niko Peterson, a senior at Animas High School in Durango and one of McKinney’s friends who helped write the bill. “Being proactive versus being reactive is going to be the best possible solution.”

    Individual school districts or counties in California, Maryland, and elsewhere have rules expressly allowing high school students to carry naloxone. But Jon Woodruff, managing attorney at the Legislative Analysis and Public Policy Association, said he wasn’t aware of any statewide law such as the one Colorado is considering. Woodruff’s Washington, D.C.-based organization researches and drafts legislation on substance use.

    Naloxone is an opioid antagonist that can halt an overdose. Available over the counter as a nasal spray, it is considered the fire extinguisher of the opioid epidemic, for use in an emergency, but just one tool in a prevention strategy. (People often refer to it as “Narcan,” one of the more recognizable brand names, similar to how tissues, regardless of brand, are often called “Kleenex.”)

    The Biden administration last year backed an ad campaign encouraging young people to carry the emergency medication.

    Most states’ naloxone access laws protect do-gooders, including youth, from liability if they accidentally harm someone while administering naloxone. But without school policies explicitly allowing it, the students’ ability to bring naloxone to class falls into a gray area.

    Ryan Christoff said that in September 2022 fellow staff at Centaurus High School in Lafayette, Colorado, where he worked and which one of his daughters attended at the time, confiscated naloxone from one of her classmates.

    “She didn’t have anything on her other than the Narcan, and they took it away from her,” said Christoff, who had provided the confiscated Narcan to that student and many others after his daughter nearly died from fentanyl poisoning. “We should want every student to carry it.”

    Boulder Valley School District spokesperson Randy Barber said the incident “was a one-off and we’ve done some work since to make sure nurses are aware.” The district now encourages everyone to consider carrying naloxone, he said.

    Community’s Devastation Turns to Action

    In Durango, McKinney’s death hit the community hard. McKinney’s friends and family said he didn’t do hard drugs. The substance he was hooked on was Tapatío hot sauce — he even brought some in his pocket to a Rockies game.

    After McKinney died, people started getting tattoos of the phrase he was known for, which was emblazoned on his favorite sweatshirt: “Love is the cure.” Even a few of his teachers got them. But it was classmates, along with their friends at another high school in town, who turned his loss into a political movement.

    “We’re making things happen on behalf of him,” Peterson said.

    The mortality rate has spiked in recent years, with more than 1,500 other children and teens in the U.S. dying of fentanyl poisoning the same year as McKinney. Most youth who die of overdoses have no known history of taking opioids, and many of them likely thought they were taking prescription opioids like OxyContin or Percocet — not the fake prescription pills that increasingly carry a lethal dose of fentanyl.

    “Most likely the largest group of teens that are dying are really teens that are experimenting, as opposed to teens that have a long-standing opioid use disorder,” said Joseph Friedman, a substance use researcher at UCLA who would like to see schools provide accurate drug education about counterfeit pills, such as with Stanford’s Safety First curriculum.

    Allowing students to carry a low-risk, lifesaving drug with them is in many ways the minimum schools can do, he said.

    “I would argue that what the schools should be doing is identifying high-risk teens and giving them the Narcan to take home with them and teaching them why it matters,” Friedman said.

    Writing in The New England Journal of Medicine, Friedman identified Colorado as a hot spot for high school-aged adolescent overdose deaths, with a mortality rate more than double that of the nation from 2020 to 2022.

    “Increasingly, fentanyl is being sold in pill form, and it’s happening to the largest degree in the West,” said Friedman. “I think that the teen overdose crisis is a direct result of that.”

    If Colorado lawmakers approve the bill, “I think that’s a really important step,” said Ju Nyeong Park, an assistant professor of medicine at Brown University, who leads a research group focused on how to prevent overdoses. “I hope that the Colorado Legislature does and that other states follow as well.”

    Park said comprehensive programs to test drugs for dangerous contaminants, better access to evidence-based treatment for adolescents who develop a substance use disorder, and promotion of harm reduction tools are also important. “For example, there is a national hotline called Never Use Alone that anyone can call anonymously to be supervised remotely in case of an emergency,” she said.

    Taking Matters Into Their Own Hands

    Many Colorado school districts are training staff how to administer naloxone and are stocking it on school grounds through a program that allows them to acquire it from the state at little to no cost. But it was clear to Peterson and other area high schoolers that having naloxone at school isn’t enough, especially in rural places.

    “The teachers who are trained to use Narcan will not be at the parties where the students will be using the drugs,” he said.

    And it isn’t enough to expect teens to keep it at home.

    “It’s not going to be helpful if it’s in somebody’s house 20 minutes outside of town. It’s going to be helpful if it’s in their backpack always,” said Zoe Ramsey, another of McKinney’s friends and a senior at Animas High School.

    “We were informed it was against the rules to carry naloxone, and especially to distribute it,” said Ilias “Leo” Stritikus, who graduated from Durango High School last year.

    But students in the area, and their school administrators, were uncertain: Could students get in trouble for carrying the opioid antagonist in their backpacks, or if they distributed it to friends? And could a school or district be held liable if something went wrong?

    He, along with Ramsey and Peterson, helped form the group Students Against Overdose. Together, they convinced Animas, which is a charter school, and the surrounding school district, to change policies. Now, with parental permission, and after going through training on how to administer it, students may carry naloxone on school grounds.

    Durango School District 9-R spokesperson Karla Sluis said at least 45 students have completed the training.

    School districts in other parts of the nation have also determined it’s important to clarify students’ ability to carry naloxone.

    “We want to be a part of saving lives,” said Smita Malhotra, chief medical director for Los Angeles Unified School District in California.

    Los Angeles County had one of the nation’s highest adolescent overdose death tallies of any U.S. county: From 2020 to 2022, 111 teens ages 14 to 18 died. One of them was a 15-year-old who died in a school bathroom of fentanyl poisoning. Malhotra’s district has since updated its policy on naloxone to permit students to carry and administer it.

    “All students can carry naloxone in our school campuses without facing any discipline,” Malhotra said. She said the district is also doubling down on peer support and hosting educational sessions for families and students.

    Montgomery County Public Schools in Maryland took a similar approach. School staff had to administer naloxone 18 times over the course of a school year, and five students died over the course of about one semester.

    When the district held community forums on the issue, Patricia Kapunan, the district’s medical officer, said, “Students were very vocal about wanting access to naloxone. A student is very unlikely to carry something in their backpack which they think they might get in trouble for.”

    So it, too, clarified its policy. While that was underway, local news reported that high school students found a teen passed out, with purple lips, in the bathroom of a McDonald’s down the street from their school, and used Narcan to revive them. It was during lunch on a school day.

    “We can’t Narcan our way out of the opioid use crisis,” said Kapunan. “But it was critical to do it first. Just like knowing 911.”

    Now, with the support of the district and county health department, students are training other students how to administer naloxone. Jackson Taylor, one of the student trainers, estimated they trained about 200 students over the course of three hours on a recent Saturday.

    “It felt amazing, this footstep toward fixing the issue,” Taylor said.

    Each trainee left with two doses of naloxone.

  • Elderhood – by Dr. Louise Aronson

    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.

    Where does “middle age” end, and “old age” begin? By the United States’ CDC’s categorization, human life involves:

    • 17 stages of childhood, deemed 0–18
    • 5 stages of adulthood, deemed 18–60
    • 1 stage of elderhood, deemed 60+

    Isn’t there something missing here? Do we just fall off some sort of conveyor belt on our sixtieth birthdays, into one big bucket marked “old”?

    Yesterday you were 59 and enjoying your middle age; today you have, apparently, the same medical factors and care needs as a 114-year-old.

    Dr. Louise Aronson, a geriatrician, notes however that medical science tends to underestimate the differences found in more advanced old age, and underresearch them. That elders consume half of a country’s medicines, but are not required to be included in clinical trials. That side effects not only are often different than for younger adults, but also can cause symptoms that are then dismissed as “Oh she’s just old”.

    She explores, mostly through personal career anecdotes, the well-intentioned disregard that is frequently given by the medical profession, and—importantly—how we might overcome that, as individuals and as a society.

    Bottom line: if you are over the age of 60, love someone over the age of 60, this is a book for you. Similarly if you and/or they plan to live past the age of 60, this is also a book for you.

  • Aging Backwards – by Miranda Esmonde-White

    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 this book, there’s an upside and a downside to the author’s professional background:

    • Upside: Miranda Esmonde-White is a ballet-dancer-turned-physical-trainer, and it shows
    • Downside: Miranda Esmonde-White is not a scientist, and it shows

    She cites a lot of science, but she either does not understand it or else intentionally misrepresents it. We will assume the former. But as one example, she claims:

    “for every minute you exercise, you lengthen your life by 7 minutes”

    …which cheat code to immortality is absolutely not backed-up by the paper she cites for it. The paper, like most papers, was much more measured in its proclamations; “there was an association” and “with these conditions”, etc.

    Nevertheless, while she misunderstands lots of science along the way, her actual advice is good and sound. Her workout programs really will help people to become younger by various (important, life-changing!) metrics of biological age, mostly pertaining to mobility.

    And yes, this is a workout-based approach; we won’t read much about diet and other lifestyle factors here.

    Bottom line: it has its flaws, but nevertheless delivers on its premise of helping the reader to become biologically younger through exercises, mostly mobility drills.
