Exercise and Fitness

Not sure what you mean by "senior", but I'm 55. I started running around age 28 and ran for fitness up until about 45. Not a lot, usually 15-20 miles per week. For a few years between 45 and 54, I hardly ran at all, basically life just got too busy to fit it in.
But I was always proud that I could go out and do a 3-miler at any time. I wonder what percentage of Americans can do that?

Now I've been back at it again. I take longer runs now, and go at an easy pace. I'm in the north too, but this winter has been exceptionally mild. I also fear being injured by slipping on the ice! I load lots of npr podcasts to my mp3 player, and feel like I'm feeding my mind at the same time I'm strengthening my body.

When I first started running, I also greatly admired the "older" people who show up at races. I still do! I hope I'm still out there when I'm 80. I feel great now, and hope to be able to keep it up.
