Since covid, I am immediately suspicious of anything that starts out with “Studies show” or “Studies indicate” or “Studies reveal”. Blah, blah, blah. I’m 74, still cut and split firewood, mow my own lawn, whack my own weeds, shop, cook, and enjoy a good bourbon. My hair is snow white, but I have plenty of it, and no wrinkles. If I died my air, I could pass for 50, no problem. Stick your “studies” where the sun don’t shine. We’re not all alike, and that’s a good thing.
Genetics plays a role too.....some families have histories of longevity - others might have members who suffer from heart issues at a young age. Also male and female differs as well as injuries that slow us down more than aging.
Gentlemen: Never, never "die your air."
Nor should you dye your hair.
