Don't they all die from the last bite?
This guy was supposedly bit on a number of occasions, and he'd go in his back yard, and suck on some leaves, and recover from his "bite". He figured that he built up and immunity to cobra venom. He didn't realize how wrong he actually was until it was too late to get to a hospital. They speculated that the cobra's may have bit him on those few occassions but didn't inject venom into him for whatever reason. The last bite he recieved, he did his usual suck on leaves in the backyard and figured since he beat the venoms attack before and did not need to seek anti-venom. So, he had plenty of supposedly last bites that may have ended his life, when actually, they weren't true bites until the one that did him in.
