Re: Vampires. We all know that vampires can only survive by drinking human blood. If each vampire finds a victim (who then also becomes a vampire) say, once a month, did you know that after only 2.5years everyone on the whole planet would be a vampire?? And then all the vampires would die of starvation because they don't drink each other's blood, although I think they can survive on the odd rat, so then we'd have a world full of vampire rates too!!!
