I'm 40. I started riding a few years ago after a number of years as a couch potato. I feel like a new person. I've been lucky to meet and ride with any number of people who are in their 50s, 60s and 70s, and they've really made me really rethink aging. God willing, it is possible to remain active, energetic, healthy, etc., etc. I hope I'm just like them in 20-30 years' time.
