having all the time in the world to do everything might just paralyze me into doing nothing. after all, what incentive would there be to take action NOW, if i was going to live forever? there'd always be another opportunity. on the other hand, since time would be endless and death an impossibility, i might just take the opposite approach and plunge headfirst into all those activities i was too frightened to attempt before, like climbing a skyscraper, or diving into a shallow stream full of piranhas, just to see what it was like. after the first hundred millenia though, when the novelty wore off, i'd imagine it would get quite blase. especially if i was alone in my immorality.
this is a really interesting question actually. the value of immorality would probably be completely different if it was a rarity, if it was yours alone, as opposed to if it was something everyone was given, by birthright. ignoring the problem of overpopulation and an eventual crippling lack of resources, being alive forever on earth with other people who are also alive forever might just silence a lot of the worries that typically consume us in everyday life, such as the desire to build a (singular) career. if you were alive forever, you'd have time to develop all your skills to the level of perfection... making gods of all of us?
