I used to work with this tiny little gal, she was rary rary preasant to rerk riv.
She was always taking this and that supplement, drinking that fungus crap. Oh God it was awful.
There I was, 6'3", 350lb's, exercised maybe 20 minutes in my entire life all totaled, ate McDonalds every day ... I think in 20 years, I took 3 sick days? She was sick constantly. Always had a cold, going to the doctor, running her kid to the doctor because it woke up at 6:31 instead of 6:30.
Had an aunt,, drank a gallon of whiskey and a case of beer every week and lived off government cheese and butter sandwiches, she lived to be 91, and would have lived longer but she had to start dialysis (at 91) and didn't want to do it.
My grandmother is 99 ... never been to the doctor except for checkups. Doesn't take any medication. Lives by herself on a 3rd floor apartment. Does her own shopping, cooking, cleaning.
All the women on my wife's side of the family have died from, had, or still have, cancer.
It's all gene's and mental state I believe.
You can suck fungus juice till you're green in the gills like that gal I knew, but it's not gonna add a single second to your life.
YMMV.
