Holy shit, and there I was, in my 60s, walking 20,000 steps a day, riding a bike for an hour, plus swimming a mile. Now I am 70, I stil walk every single day of my life. Long disances. My sister, at 68, is still turning cartwheels, doing the splits, dancing vigourously, and more.

I am not wrinkled, am slighltly grey - my sister not a single grey hair.

Forgive me, but I don't think you are factual.
