I like and participate in the whole jumping off shit and evading and climbing, but myself and many other people have been doing that for years and calling it something just sounds weird. I skateboard sometimes and I guess thats why I like climbing and jumping, and of course falling. The best is when you get to put your tricks to use when the po po come a calling. When I was like 16 the cops came to my friends house and we were smoking bongs on his back porch, bacon comes a rolling, there was a shed, I ran at the shed, vaulted onto the roof and down the other side, cops say, no joke, "HOLY FUCK" and didn't even attempt to spot let alone catch me. Tree climbing is another major interest of mine which leads me to say like monkeys us humans enjoy climbing and jumping and the such, which is why "parkour" or really gymnastics is a very natural sport, like running or wrestling.
