I once had a classmate who does this, jumped on the 2nd floor of our building and got away with it with nothing but a sprain. This of course inspired me. So I tried to do a handstand (dun' ask why) for 10 seconds and went all WOOO!! when I did it. Then I tried a backflip next. Bad idea. Today, I can leap quite a distance, but there's nothing much to leap to 'cept a few ledges where I'm from so I kinda do it a little I guess.
