It’s been sad to watch as so many of my old friends begin to suffer from serious health problems. Although sometimes those conditions are caused by genetic factors, I can’t help but think that a lot of it has to do with one’s lifestyle decisions. I made a vow when I turned 50 that I would live long enough to watch my grandchildren grow up and maybe even get married.

That meant staying in shape, of course. I do stretches each morning to stay limber, and I swim and play tennis more often now than I ever have in my life. The key has been to stick with low-impact exercises that are easy on the hips. As I’ve gotten older, I’ve placed more importance on cardiovascular health, as well. By working my heart and keeping my cholesterol down, I honestly believe I’ve added years to my life.
