Wow, a post from 2010 and it finally applies! At 73 I'm still in better shape than the average adult but it's getting to be much more of a struggle. Some people I meet in their 70's are in AMAZING shape and are truly an inspiration. I just want to stay healthy and keep doing things I enjoy (skiing, hiking, riding) and traveling with my wife. I'll be skiing with our grandkids here in Taos in about a week and hope to do that for a few more years. Oh, and skiing at low temperatures - years ago I skied at -32F with my kids on two different occasions, once at Stowe, VT and then at Mt. St. Anne in Quebec. Our youngest daughter was 5 when she learned to ski at Stowe that trip. Coldest road cycling was in the teens and it wasn't too bad until I started going downhill at 30-40 mph. Brrr!
