Maybe but it seems like your parents have their health and were taking care of themselves.

I'm in my thirties. I'm already suffering from obesity, have chronic pains in the wrists and shoulders and leg, and my hearing and vision are starting to deteriorate, and I've had multiple bouts with gout that leaves me barely able to walk for months at a time.

If my thirty's are already this bad, I can't imagine lies in store in my 40's, never mind 80's.
