What is it about them??? You can do as many as you want but you still need to do more!
It's kinda funny if you think about it - we're already sorta defying physics / gravity by riding on 2 wheels, but that's not even good enough. We need to say "hey look at me balance 600 lbs on an area the size of a baseball while doing 65 km/h!"
I guess it's just like breasts. No matter how many you see or feel you just don't lose interest in them!
