Neurotic
I plan on living forever. Or die trying.
I'm sorry for your friend, that must have been one hell of a critical miss
This comes off as a joke, but believe me, it's not. I know people who fell and hurt themselves by falling on level ground. And jumping from second stair (about 45cm (cca 20 inches) height difference (broken arm and leg respectively). Any jump / fall is dangerous.
I semi-regularly jumped from the balcony (first floor) of my house even as a kid and well into teen years. The worse I've had is landing on half a brick hidden in earth, landed with my heel onto it. It hurt, but nothing broke. Its not unrealistic, but its not hard either. Esp. if you're trained in Athletics / Jumping / Parachuting...maybe I was just lucky.
