I agree with Rylak. The theory of immortality is a very intriguing concept, both giving you internal happiness and sadness. The knowing that you can never die, but also knowing that you will surpass any mortal in life. Anyone who you know will die. Anyone you love will die. Everything you ever have, even a piece of paper will be gone at some point. Although, t the sane time you will be able to see life pass, and become anew. New technology, new ideas, new everything! And while thinking about theories, what if, t some point, time travel is possible? You could go anywhere, and do anything. Anything you could ever want! Single handedly destroy the entire nazi army if you like. You are invincible! Soon you might even learn to ignore the pain of watching life pass, and enjoy doing, literally, whatever you want.
