If you could live forever, could you guess now when you would choose to stop existing? (Comment)
With perfect health and no loss of mental capacity? Probably Never. Too much to learn, do, see, and explore to ever give up....
Sure. Upon obtaining the ultimate bit of information to be had and having the final experience available. Until then: Rock on.
If you could live forever would not the concept of time be rendered meaningless? The notion of forever or eternity implies no beginning or ending.
That is incorrect. Forever is confined to time.
Excellent question and one I think religionists are afraid of. Living to 100 is easy. Try 1,000. That would be unimaginable. Everything and I mean everything becomes boring when it is repeated over and over.
I would answer not when I would choose to stop but how.
I'm thinking somewhere around 250 years would be my limit, give or take depending on circumstances.
I'm already deeply tired of the human condition after less than 62 years. I am merely curious about how some things will turn out, and I might like to be a third-wave colonist someplace like Mars just to see what that's like. But on the other hand if the world degenerates into some kind of fascist dystopia none of that would be possible and I'd check out sooner. And if we made First Contact and were given a Great Leap Forward by some beneficent interstellar species, I might stay longer. It's very much like the decision whether to watch a TV series all the way to the end or not. (Or past season three where the last original idea was put forward).
Immortality, I think would have it's pluses and minuses. I really can't say, if I was able to extend my life I would want to be healthy. Very hard to say...watching everyone die. Being able to process all the change is difficult. I think Ann Rices books portray this beautifully. My answer is I do not know.
