Why do people crave the taste of blood?

Well most of us have heard of VAMPIRES right well you might want to be like them and you think you need blood sometimes you like "i can bite harder than you!" just so can you taste there blood.

You may possibly be a vampire if you crave blood often.

Actually, that's partly true and no not really there are people that need iron and since blood is really good because of its metallic taste and because of the oxygen in it people often get hurt allot and taste it to dissolve the pain but at the times its just an addiction which is really wrong for you or anyone to do, and some people drink it from other people which allows them to be pleasured (both people) if you ever tried on another person both of you will encounter this as a pleasure not a bad thing. but its better if you don't, you could loose so much red blood cells that the white blood cells will encounter it as an enemy and fight against it eat meat or something that contains iron never give in blood NEVER!
