Not all poisonous snake bites are deadly (at least in North America). I live in an area with a variety of poisonous snakes and grew up in an area litterally infested with several breeds. Snake bites are rare and death resulting from one is extremely rare. The best cure for a poisonous snake bite is not getting bitten. I only know of one breed of poisonous snake (water mocassin) in N America that is thought (might be urban legend) to be territorial and "may" attack a person. All the rest have to be kicked, stepped on, poked with a short stick, etc in order for them to bite. I grew up in the woods of East Texas and still spend much time in the woods. I have come across many snakes and even had a Copperhead as pet when I was a kid. I have never been bit (by a poisonous snake) and never known first-hand of anyone else being bit either. It is very rare. It is so much more rare than people think. I have also had a non-poisonous (ball python) wild snake as a pet and this snake I spent much time handling. Even in handling a snake regularly (at least this particular breed) you really have to do something to make them angry in order to get bit.
