I'm seventy but I still like to ride my Peugeot bycycle that I bought back in 1972. It is the best bycycle that I have ever had and it rides so easy. It's 12 speed and I need the low gear to get up the hills. The part of town where I live is on the side of town where there are no through roads a little ways from my location. I ride over there and don't have to worry about traffic.
Lately my joints are going bad, at least they seem to be. It hasen't slowed down my mobility yet and I plan to keep going as long as I can. Maybe with spring comming up I can get more exercise, I love push mowing the yard and stuff like that. I did keep busy almost all the time but since retireing I can't get motivated to do much. Anyway I enjoyed my bike ride.
Too bad I'm not 40 again, I could ride 20 miles easily back then.
