I've heard it's been speculated that the soul or consciousness lives in the neural tubes of the brain. I don't believe it. The whole idea of souls comes from superstition, and there is no credible, conclusive evidence that we have souls. Instead of worrying about it, why not be contented with having a brain that lives at least as long as you do, and use it to leave a positive mark while you're alive. That's the only sure way to live on.
