I am not very sure if it exists nor is it my main concern. I don't like the idea of "plan for the afterlife" and instead think it's better to live now and make the most of your life.
Nope. I'm of the firm belief that there's nothing after you die; I don't believe in souls, and I think people/animals are basically complex organic machines.
Not really, I'd like to think that everyone does their own thing when they die, and that people who do believe in a heaven can go there, but I don't personally believe in a heaven, and hope I come as something else or that my soul can hang out as a ghost. =D
