Ask yourself - would a UFC fighter given their agility and reflexes actually trip over a power cable and destroy their knee, or would they hurt it elsewhere and then make a worker's comp claim?
It's not about reflexes or agility. Anyone at anytime can pull or tear shit for the dumbest fucking reasons. You could be walking and just take a step and shit fucks up. Tear something, pull something, hell even break something.
I've known people that played high level sports and shit just broke for the most fucked up reason. I got a cousin that was just walking across the road and her foot just slightly twisted and her foot broke. Knew another guy who played hockey and played hard as hell. Side of a door just tapped his elbow and it broke it by the joint. Shit just happens sometimes. Hell. There's videos on youtube where the mother fucker should be dead and they walk away with not a scratch.
Freak things happen. Hell Fedor should be a quad from getting slammed. Must be fishy!
