My husband's grandpa just turned 95
he still drives, dances and bakes (he used to have bakery stores for years). He has a farm that he still takes care of it. And he had bypass surgery in his 70's!
My hu*****and told me the same thing - yet I don't think my hu*****and is eating healthier or exercising more :P. I said he has to make sure that I leave first :)
