You do close to 500+ races and 1000+ group rides and rack up 130,000+ miles on top and you get lots of experiences with lots of different things, and it also lets you see and witness lots of other people doing things.
Most damage to my bike was when I unclipped in a parking lot with new cleats, skidded on the asphalt and fell over, all about one mile per hour. Tacoed my wheel and jacked up a shifter. Real bummer.
Have a couple of teammates who have fallen over at very slow speeds (not being able to clip out on crazy steep dirt climbs, speed bumps in parking lots, catching a foot on a wheel on a 180 degree turn, etc) who have suffered huge and long-lasting hematomas and the like.
Ride around enough and you'll always find someone with a story.
