I'm 65 and retired for 8 years now. I work on house and in the yard and garden for a couple of hours a day and spend a couple of hours a day at the gym. Two light beers a day,good nutrition, social life, pets and stress reduction have kept me helathy enough to hit the trails whenever I want.

Herniated a disc in my back about 2 years ago that set me back some. That seems to be behind me now, however, and I'm as good as I was but more cautious.
