actually on the 'discovery channel' they had some show (science of fighting or some crap like that) last night that showed some dude knee kick a 'dummy' (like the ones used for testing car crashes) and the scientist guy said something like "thats what we see in a 35mph car crash". i only saw the preview, not the show. i swear to god, and im pretty sure it wasnt the lsd i had taken a hour before.
