Let's be clear on this; unless you're a masochist, falling isn't really that much fun...it generally hurts...sometimes a lot and it can put you out of commission for a long time if you fall "just right."
On the other hand, if it weren't for the falls, you'd never have the incredible stories to tell other people out there when they ask you "Where'd you get that scar?" Ultimately, we probably remember our worst falls much more vividly and with more fondness than we do our greatest riding accomplishments; there has to be something wrong with that.
