I dunno, after you've won so many races and lost so many races, it all just seems so elementary to me.
I think racing, for the most part, is a youthful occupation. As you mature, your thirst for speed and competition begins to subside in favor of exercise, recreation, motion, scenery, and the holistic synergy of cycling. You develop a greater appreciation for other aspects of cycling, as well. Though, at the same time, speed is not totally forgotten. It's sometimes revisited and enjoyed upon occasion.
Perhaps that's the reason the Fred population increases with maturity...
