short naps good, long naps bad

As I move deeper into middle age, I consider the luxury of a mid-afternoon nap to be one of life’s great pleasures. 30 minutes is about right, according to this article. After reading the article though, I can’t help wondering if longer naps are more of a symptom of other health problems or poor lifestyle choices rather than a driver of them.

My personal prescription for a little mid-afternoon pick-me-up:

  1. Read a book (Kindle is okay, computer or phone not recommended) until you start to feel a bit sleepy.
  2. Close eyes for 20-30 minutes. Just relax, don’t put any pressure on yourself to sleep, or consider meditation if you don’t feel sleepy.
  3. Open your eyes and read a bit more.
  4. Get up and exercise for 20-30 minutes.
  5. Take a shower.
  6. Have a cocktail. Don’t overdo it, just one is good.
  7. Now you’re ready for dinner, people, or whatever you want/need to do in the evening.

Obviously this is not a daily prescription for the harried working parent. I find maybe one afternoon per month to do this, but it is oh so rejuvenating mentally and physically. I fantasize about doing this every day in retirement.

Bill Gates on 2022 and 2023

This article is subtitled “My Wish for 2023”, but it is mostly about what the Gates Foundation did in 2022. He says the world moved backward on polio, but it can and should be eradicated, and we know how to do it. Infant mortality in developing countries can be reduced by using cheap ultrasound machines powered run by smartphone apps to identify high-risk pregnancies, stretching the limited pool of medical expertise (and it seems like this sort of thing could save money in developed countries if it could be done at home in combination with a telehealth session, at a pharmacy or neighborhood clinic say in a school or library, by a technician showing up at your door at a convenient time, etc.) He is predicting a gene-therapy based cure for HIV in 10-15 years. He says a gene therapy based cure for sickle cell disease is available now, but prohibitively expensive or unavailable in developing countries where the disease is common.

The Liver King

I’m not sure what to say about The Liver King except that this GQ profile of him is worth a read. It’s slightly mocking, but he may be of the “any attention is good attention” school of marketing, which appears to be serving him well. Along with subsisting mostly on raw liver and testicles, at least when reporters are around. Why? Because “Vegetables don’t have the raw material required to produce a healthy set of testicles,” he explained. His wife, who is a dentist, and their two apparently teenage boys (who sadly, are not named Walker and Texas Ranger) appear to be okay with all this. I will admit that if the photos in the story are not doctored, this family does in fact appear to have outstanding skin. You see a lot of their skin. Unfortunately, one thing that does not produce a healthy set of testicles is steroids, which the liver king himself did admit recently to be taking.

Our World in Data Global Health Explorer

Our World in Data has a new Global Health Explorer. I’m going to pick a few metrics and see where the United States stands according to a somewhat random set of peer countries. I think it would be interesting to see where we stand as a percentile among OECD and non-OECD countries, but that would require work.

Peer countries: I’m going to pick six highly developed countries and six middle income countries: Canada, Germany, Japan, Brazil, Indonesia, Malaysia.

I’m going to pick 10 metrics.

  • Life expectancy at birth: We’re #4! (Japan, Canada, Germany, US, Brazil, Malaysia, Indonesia)
  • Child mortality: We’re #4! (Japan, Germany, Canada, US, Malaysia, Brazil, Indonesia)
  • Maternal mortality: We’re #4: (Japan, Germany, Canada, US, Malaysia, Brazil, Indonesia)
  • Homicide rate: We’re #6! (Japan, Germany, Indonesia, Canada, Malaysia, US, Brazil)
  • Deaths from road injuries (rate): We’re #4! (Germany, Japan, Canada, US, Indonesia, Brazil, Malaysia)
  • Suicide rate: We’re #6! (Indonesia, Malaysia, Brazil, Canada, Germany, US, Japan)
  • Death rate from all infectious diseases: We’re #2! (Canada, United States, Germany, Brazil, Indonesia, Malaysia, Japan)
  • Death rate from alcohol use: We’re #5! (Indonesia, Japan, Malaysia, Canada, US, Brazil, Germany)
  • Death rate from drug use: We’re #7! (Indonesia, Japan, Malaysia, Brazil, Germany, Canada, US)
  • Death rate from cardiovascular disease: We’re #6! (Brazil, Malaysia, Canada, Indonesia, Japan, United States, Germany)

There’s a lot more to glean from the graphs in terms of how much separates countries in these metrics, and of course there are many more metric and many more countries. But one thing is clear, USA USA! is not #1. And in this peer group of highly developed countries (Canada, Germany, Japan), we are not even average, we are dead last on most metrics. Asian countries tend to beat western countries on metrics related to life style, such as alcohol and drug use, and are significantly less violent. Germans are no saints when it comes to healthy life style – they drink a lot and have a lot of heart attacks. And Brazil is downright violent.

metformin and longevity

This article says billionaires are “racing” to invest in longevity treatments. Top candidates attracting funding include various gene therapies, drugs, stem cells, and old people consuming the blood of children (seriously, this is real but presumably the children are fine). This article argues a known drug called metformin deserves more attention.

why daylight savings time is unhealthy

There is a clear consensus that everybody hates setting the clocks ahead and losing sleep. There seems to be movement toward doing away with this dumb tradition and going towards all daylight savings time all year. But at least one scientist says the evidence points toward going all standard time all year.

  • There is evidence for increased strokes, heart attacks, and sleep deprivation during daylight saving time, the latter particularly affecting teenagers. There is also evidence of increased obesity, diabetes, cancer, lower income and higher health care costs in the western portions of time zones, where the shift in dawn and dusk is most pronounced.
  • The lack of morning light disrupts the body’s natural rhythms when we are trying to wake up.
  • Increased light in the evening makes it harder to fall asleep. This is particularly hard on adolescents and young adults, who have trouble falling asleep already for biological reasons and often have to wake up early for school, leading to chronic sleep deprivation affecting their already wacked-out bodies and minds.
  • Standard time is a better match for the natural rhythm of the sun, with the sun directly overhead around noon.

I would add that the time shift causes trouble in science and other technical fields, where we try to measure stuff over time and make sense of it. It also causes practical problems for people who have to travel or collaborate with colleagues across time zones (which is already challenging). Once I got a roomful of people together at 7 a.m. in Singapore for a meeting led by U.S. staff, only to find that the U.S. had changed its clocks the night before and the meeting was over. Those people were a little mad at me. I bought them doughnuts. A lesson learned there is to let your calendar software handle time zones and not try to do the math yourself. The U.S. is not even the worst – Australia has half-hour time shifts that are different in different cities not that far apart. The time shift is dumb, let’s just stop doing it.

flu and Parkinson’s

This article makes a link between flu infection and increased risk of developing Parkinson’s disease later in life. It makes me wonder if a person’s history with viruses and other infections has a more significant effect on the brain than the average person things. There has been so much talk and worry about the effects of Covid-19 on the brain, but I wonder if a lot of viruses have these effects and Covid-19 is just the one we happen to have studied incredibly intensively over the past 2 years. It’s a disturbing thought, but also suggests that vaccines for certain viruses earlier in life could reduce risk of developing dementia later in life.

what’s new with cancer?

This article is critical of the focus on new treatments for cancer, saying prevention should be more of a focus.

Up to 40% of cancers could be prevented by reducing the consumption of highly processed foods, high-calorie diets, and certain fats, increasing consumption of fresh fruits and vegetables, and getting people to be more physically active. Alcohol consumption increases the risk of several types of cancer and accounts for 19,500 cancer deaths a year. Air pollution is a major cause of lung cancer and may also increase bladder and breast cancer. And one study found that pollution in U.S. drinking water could have caused 100,000 cancer cases between 2010 and 2017…

The human costs of allowing businesses rather than scientists and doctors to shape cancer research are high. By pursuing cancer treatment options that are the most profitable rather than the most effective for the largest number of people, the medical enterprise misses opportunities to make more substantial progress…

By proposing additional measures to make prevention the priority, tackle commercial determinants of cancer, and avoid the technological quick fix suggested by war and moonshot metaphors, those seeking to reduce the burden of cancer can develop more effective and equitable approaches.

STAT

I had the impression that, smoking, air pollution, and lack of sunscreen aside (okay, those are actually three big ones), the causes of cancer were still murky, with a suspected role for various chemicals in consumer products, food, water, and the environment, but not much known for sure and luck still playing a big role. This article seems to suggest a lot more is known about the causes of cancer than I thought. That big business has captured and corrupted our government is not news, however.

East Asian people may have genetic defenses against Covid-19

It’s somewhat taboo to suggest that ethnic groups might be genetically superior or inferior to others, but when it comes to susceptibility or resistance to specific diseases, we should be willing to acknowledge this possibility. Most countries in Asia seemed to manage the Covid emergency much better than most western countries. I thought from the beginning that much better health and quarantine systems at airports must be a big factor. Somewhat privacy-invasive contact tracing measures and a willingness to restrict movement seem to be other significant differences between west and east, and you can see these even in Australia and New Zealand which are still largely ethnically European (although I say lots of Asian faces on trips on Sydney). But even given that, it always seemed like there might be some genetic or lifestyle factors to explain the order-of-magnitude differences.

Studies have shown that more people in Asia have a defense enzyme called APOBEC3A that attacks RNA viruses, including the SARS-CoV-2 virus that causes COVID-19, when compared to people in Europe and Africa…

Some people may wonder if the self-extinction of the delta variant in Japan was caused by something special in the genetic make-up of Japanese people, but Inoue disagrees.

“I don’t think so,” he said. “People in East Asia, such as Koreans, are ethnically the same as Japanese. But I don’t know why this observation was made in Japan.”

Japan Times

The “self-extinction”, by the way, is the idea that once isolated from external influxes and exposed to a largely resistant population, the virus may have acquired mutations that have doomed it.

I understand why it is politically and culturally hard to do contact tracing and quarantine in the U.S., and nearly impossible to physically restrict movement. I still don’t understand why we can’t implement effective screening and quarantine procedures at our international airports when we have had a year and a half of emergency conditions now to get that done.
