Did anyone see the show on Animal Planet about some guy who is a wildlife animal catcher once bitten by a Gila an he was allergic to the venum. He almost died. He had delt with venumius snakes all the time and was bitten by snakes with no long term effect. He was just allergic to Gila. He won't dare walk near one now, cuz the doc said if he gets one more bite, he will be gone.
