The reason i asked this question, is, as i'm sure you know, a person can become hyper-sensitive to snake venom if exposed to it in large quantities (as through a bite), and can suffer even more severe complications in the event of a second bite. Second, hyper-sensitivity to the antivenin for the species can also develop, making a bite situation even more perilous. Personally, I haven't been bit (knock on wood) and don't plan on it, but if I were to get bitten by say, a black mamba, or any other seriously life threatening snake, i MIGHT consider giving up keeping that species, not because i'm afraid of the snake, but because if i got bit once, i can get bit again, and I'd rather have many years in front of me keeping many varieties of venomous than having that time potentially shortened by keeping a one particular one....but who knows, maybe I would still keep it, i haven't been bit, so until then I can't really say...
