I think steve was bitten too many times. I realize he takes that risk being the croc hunter but he isn't a robot, he is a human he can only take so much. But i guess he is so accustomed to it, that it don't even phase him.
justin78 I hate to say that I don't know how many times Steve has been bitten but I do know that he would this if he were to answer your question "That he/I has/have scars on scars."
