ehh, a lot of times you don't feel shit.
i remember back in the day, i was up at mt. snow doing a downhill mtn bike club ride... and some dude took a digger, got up, went to get back on the bike, only to realze that he couldn't grab the handel bar with his rleft hand, because his wrist had completely snapped backwards and was just dangling there. He didn't even notice until he realized he couldn't grab the bar with it. then he started freaking out. lol
