Oh the joy and curse of aging......age is a real battle that unfortunately will all succumb to. Just depends when you want to call it quits. I a sure you have read about the 102 year old cyclist in Europe - he is my idol! I keep saying that I plan to ride my bikes when I get to be 100 and beyond. Thinking strongly, living cleanly and riding constantly will help your wings stay young even if they lose a few feathers along the way.
