More relevant questions: if you become a werewolf by being bitten by a werewolf, what made the first one?
Why can werewolves only be killed with a silver bullet? How did people kill them in the centuries before guns? Silver arrows? And why silver?
Have any authors attempted to address these questions? Any folktales about them?
Also, doesn't anything silver work? Silver daggers? -- corvus13
My personal recommendation is to stay indoors and not go out during times of the full moon. I have so far been successful in avoiding all lycanthropes in this manner... sjc
AFAIK, all silver should word, even the touch causes skin burns. I can't remember the source, though. Also, in contrast to vampires, werewolves can enter your house, without being invited. For home safety, I always keep a herd of silverfish ;) --Magnus Manske
