We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
It's a mystery to me why, since I began a serious exercise program almost exactly two years ago, grey hairs are growing out brown, and my hair is thicker. So testifies my Sicilian barber of 20 years. My body has changed in many desirable ways - less fat, more muscle, cut abdomen (somewhat), better posture, tougher all over - but I do not exercise my hair at all and use no Rogaine, no hair dye.
Could it just be diet? I have tried to up my protein intake and go very easy on carbs except maybe in restaurants. I love mashed taters. Or potato chips which I also love. I tend to avoid vegetables unless in a Thai concoction, or unless cooked in garlic and oil. Or in bacon. Tomato is not a vegetable. I also tend to avoid fruit unless in a banana or strawberry protein smoothie because I do not like sweet things very much and, when I want some, it is never satisfying and makes me feel uncomfortable. I have always preferred savory to sweet. Generally-speaking, my program has lowered my appetite quite a bit so I focus on protein because I am told to. I do like a steak sandwich.
One case is just an anecdote, so it means nothing. I do wonder, though. Hair is mostly genetic but this change is odd.
Getting regular exercise may help slow the aging of your body's cells, a new study finds.
Compared with the people in the study who didn't exercise at all, the highly active people had a "biological age" that was about nine years younger, said study author Larry Tucker, a professor of exercise science at Brigham Young University in Utah.
In the study, Tucker looked into this relationship, and found that the people who had high physical activity levels had significantly longer telomeres than the people who did not exercise at all and the people who exercised less frequently and less intensely.
In particular, the men in the study who exercised at the intensity and duration equivalent to 40 minutes of running five days a week, and the women who exercised at the equivalent of 30 minutes of running five days a week, had telomeres whose length suggested their cells were nine years younger than the cells of the people who did not exercise at all.
Interesting. It has long been known that severe weight loss, such as following surgery is bad for the hair. You tend to lose a lot of your hair. I sure did. It has been ten years and it never came back. I'm doing low carb now, maybe at last I will grow more hair.
I made similar diet changes (increased protein & veggies, cut way back on carbs & sugar) a few years ago to combat my diabetes. Working closely with a doctor for 4 months I went from A1C of 8.0 to 5.8 and lost 50 pounds without additional exercise.
I started coloring my hair more than 30 years ago (usually bimonthly at least) but eventually noticed after the diet change that I don't need to anymore. At 61, my hair is fuller and retains it's natural color better than 30 years ago.
I really hadn't thought about it much unless I went by the hair coloring packages at the store and remembered I didn't need them.
Maybe it is more than a fluke but based more on diet than exercise?
I heard a piece on Dr. Cynthia Kenyon's work on Radiolab. In the lab they had manipulated the genome of nematodes and had doubled the nematodes life span. She then added sugar to the nematodes diet which cut the life span in half. Since then Dr. Kenyon said that she has cut all sugars, and most carbs, from her diet.
