If you had the choice, would you choose to live a normal human life span, an extended one (like 500 years), be immortal in the sense that you wont die from diseases or ageing, or immortal in the sense that you cannot die from anything, and will live to the universe's ending?
Extended, like 500 years. I want to see where this planet is heading, but I don't want to live forever, life would just get boring.
Normal human life. It'd suck to see everyone dying around me while I live on. Besides, 80 years in this world of turmoil is enough, death is a blessing. And I figure our lifespans are what they are for a reason, there must be some sense behind it, be it by design or just naturally occuring. We have our time and that is enough. 500 years or forever would allow us to be lazy. 80 years (more or less) is long enough to get what we need done, but not so long that we forget to get it done. Plus, immortality would become a major drag, as you exhaust the things you can do. Eventually you've done everything or close enough to it that the thrill is gone. After a million sunsets, would you still be interested? After climbing every mountain, jumping out of a hundred planes, having sex with many beautiful women, done every drug, taken every risk...what then? A never ending continuation of days, more of the same. For this reason, I also see the Christian heaven as a hell of horrors. No time, so nothing can move or happen. No space for it to happen in. Just basking in God's glory. Like staring at the sun, eyes, clamped open, without the comfort thought of eventual death or insanity for a release. Imagine a world where death/suicide were impossible, and you can start to see what hell is like. Sure makes death, the long sleep, the slow rot, the eternal night, look like a blessing rather than a curse.
