I'll be immortal, dying right now is too early, still haven't done the things I want to do In life, still haven't found the girl that won't break my heart.
being immortal would be so miserable, you can't possibly make any human connections because eventually they'll all die. Eventually you'd have experienced every possible thing a person can do and you'd end up just a jaded, miserable person who can't die. This doesn't even factor in the idea of immortality without eternal youth, you'd eventually just shrivel up and live a miserable life dependent on other people to do your basic needs for you.
