What is a vampires lifespan?

Vampires are make believe creatures. ANSWER: True but just talking about the legends the life span is forever unless killed. <<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>> Okay, lets get one thing straight. Vampires seen in movies like Dracula, do not exist. They are not like that. <About to pull out hair and scream if I have to answer another one...> But vampires do exist. Not the kind from Hollywood, but they are real. In books, they can live for centuries without end. Ideally, they don't live much longer than the rest of us. And when you are around one, you won't know it. And when you are talking to one, yup, you aren't saying what you wanted to say. More like the things they want you to say. No they do not live forever, but they can die very easily. Not by knives or guns, but by going for more than 2 weeks without blood. Believe what you wish. I always lived by this one rule though: "Never be sure of a fact until you have seen the real fact for yourself." That and have an open mind to the "unbelievable and the impossible."
