I don't know where cyclingirl is, since she is older than I, but really cycling keeps you young and full of fun.

http://www.cccts.org/photos.html These photos are from a cycling organization with its membership and participants mostly over 50, several over 70 yrs. old from British Columbia. However because they cycle often, it is difficult to guess their chronological age. My partner has done 2 bike trip tours with this group so I hear of the ages of its participants. Each trip he rode about 500 kms. over 10 days. If you look at some of their bikes,...really, not all bikes are racing looking bikes at all.
