I've been bitten a bunch of times all over my hands and arms by snakes. The worst one was when I was taunting a WC garter snake I was keeping with a goldfish. The snake missed the fish and took my index finger to about the first knuckle. I was young and kinda shocked so I sort of shook my hand then flicked him on the head. I relaxed after a minute, laughed at myself and then removed the snake. A friend of mine almost lost a finger to his adult iguana but it didn't seem to bother him much for a guy that can't tolerate any snake being out of it's cage in the same room he's in.
I feel a little light headed... maybe you should drive...
