Being immortal is just something that most people would not be able to coper with, and believe I'd be one of those. It sounds devastating and depressing, as some people have already pointed out.
Immortality (as long as there will be a way to kill myself, like the things with vamps). I'd want to see the world, the way I can't see it in a normal lifespan.
Food is amazing, I would never give it up.
