Ok, this was two years ago.... Just finished a 24 hour shift as traffic controller and im talking to another security guard (that was where i was gonna go to work the day after xP) and i turn around and i se this guy stiffen up like a tree and just falling to the ground and started shaking... Luckaly the gurd had a handheld so we could call the festival medics, turned out he was epileptic and hadnt had a seizure in over 15 years
