I had recently posted that I wished there were more epidemiological studies that tracked light exposure / time outdoors:

Disrupting Health Care Using Deep Data and Remote Monitoring: Michael Snyder, Ph.D.
https://www.youtube.com/live/Mv7aBcqcKsQ?si=gF33tYL6smgfwhp7Lots of interesting points, esp.
- [5:28] avg. human body temp. is 97.5 deg. F ; variation in baseline make the definition of 'fever' problematic
- [37:35] blood oxygen drops during airplane flights
(I knew that before watching this video, but did not know a few decades ago when pregnant) -

Karsenty: Osteocalcin and the Regulation of Muscle Mass
https://youtu.be/3bDwBRM2GKE?si=_NIbnkUi5l-8XFeC
older video, uploaded 19 Sep 2012
- bone is an endocrine tissue
- effects on aging
- undercaboxylated osteocalcin regulates insulin secretion, insulin sensitivity, testosterone secretion
- undercarboxylated osteocalcin promotes myoblast proliferation & muscle regeneration
- osteocalcin KO mice have decreased muscle oxidative capacity [10:40]
- study conducted on female mice to minimize effects of testosterone on muscle
- Esp inhibits osteocalcin by carboxylating it
- 21:31 summary slide

re: 5:40 Type of exercise for longevity
People usually play tennis outdoors. It would be nice to see 'time spent outdoors' and 'timing of outdoor light exposure' as a variables in more epidemiological studies. Outdoor time/natural sunlight exposure has an effect on circadian rhythm entrainment (morning exposure) and on the development of myopia in children (afternoon exposure). Perhaps it also has an effect on aging and age-related diseases. Perhaps fitness trackers could be modified to gather these data.
According to the study*, they 'Adjusted for age, sex, weekly volume of all LTPAs, smoking, education, income, drinking habits, and diabetes'. LTPA = leisure time physical activity. I would like to see an adjustment for time spent outdoors. I'm also wondering if playing tennis increases grip strength.
Of course, everything that turns up on search is about how tennis players can improve their grip strength - not the other way around.

re: supplements
there's some compelling epidemiological evidence on glucosamine and longevity; it is derived from shellfish, so not for people with shellfish allergy* Various Leisure-Time Physical Activities Associated With Widely Divergent Life Expectancies: The Copenhagen City Heart Study

The Dog Aging Project that aims at Helping Dogs Live Longer
https://youtu.be/YwmkGLqi018?si=rmOcMSpsWsWUCD-HI was really disappointed about the NIH funding cut - this project is important for both dog and human health. As Dr Kaeberlein points out, it's also great in terms of public relations for geoscience and science in general.

It's an open science project - the data are available to qualified researchers.

5 min. interview with David Gate on CXCR3 expressing peripheral T cells and Alzheimer disease.

I wonder if thiamine deficiency increases CXCR3 expression?
