Between driving junk, and fixing them all the time, maintaining 4 acres of lawn, at this house, and still moving the household from the old place to the new place, and keeping up the 1/3 acre lot of the old house. Repairing and remodeling a 120 YO farm house, I get plenty of exercise. I eat sensibly, and am slowly dropping weight, 230 lbs at 6 feet. I'll be 70 in January.
Whoever said getting old, ain't for sissies was right. Hopefully I'm not a sissy...
My father lived to 92, and he never stopped moving, so I do believe that is true. Once you become sedentary you go downhill quickly. My mother made it to 99, she stayed by herself in assisted living until the last month of her life.
