On the other hand, my parents and their gang of friends are all in their 70's and 80's, and they act like complete spring chickens and are in excellent health because they choose to take care of themselves and live young. I fully expect my parents will make it into their 90's, so the genetics are there that I will to barring accident or cancer. I've seen people whose bodies break down long before the end of their life; I don't want that kind of life. It is preventable. I much prefer to think that in my 80's I'll be like my parents, still traveling and enjoying life without any serious medical issues holding me back.
