That's funny, because I was thinking I should have made my 3 a 2 on that one after I answered. I originally tried to make 2 questions, one about living for 1000 years and one about living forever. But lj cut me off at 15 questions, so I had to delete the one about 1000 years.

My personal answer is that I'm pretty sure I'd enjoy living 1000 years, and probably even 10,000 years, but am also pretty sure I would hate living forever. I tend to think that either I would be insanely bored, or I will have learned and grown so much that there is no meaningful sense in which the original person I was still exists after that long.
