Gave up cycling at age 17 when I got my first car. Resumed it in grad school a few years later when I needed a way to get from my apartment to campus and never quit riding from then on. The number of miles went way down as the years accumulated and it got less comfortable to ride even using expensive bikes. In 2000 I discovered the benefits of riding recumbent bikes and then trikes. I'm sure I rode three times the number of miles at age 60 as when I was 25. Like Clark Gable in Gone with the Wind, "My dear, I don't give a damn" (what anyone thinks of my riding these strange bikes and trikes).
