The real questions

If a ginger bites you, you are already lost for your next life

Well, obviously nothing. Gingers are normal humans just like everyone else and-
*fullmoon rises*
*hair starts to turn ginger*
*growls in irish and runs away*

Well there's nothing you can do your screwed

It depends on where the bite is
If its on your arm or leg just cut it off but if its somewhere like your neck you arr dead with no chance of survival
