I've never understood people who say they'd like to live forever. It just doesn't make any sense to me. The oddest thing is to listen to someone who talks about how it is - not probably or hopefully - going to happen in their lifetime. I once had an acquaintance who spoke of it so seriously that it was religious; he honestly believed (possibly still does) that he will not die.
You have the ones who are so absolutely terrified of death that they desperately grip onto the concept of immortality; a science fiction replacement for an afterlife or reincarnation they do not believe in. (Tangent: Why do so many people reject the idea of open casket funerals. Death is just too horrible to even observe, let alone having to reconcile that it will one day happen to them? "Think of the children" is a common argument, which is bullshit; perhaps such a large number of adults are so fearful exactly because they were never exposed to it.)
You have people who use the idea as a fantasy that someday they will do all the things they want to do, but don't have the time, money, or motivation to do today. This category is depressing, because I don't understand how someone can believe that an extended future would magically fix whatever is holding them back right now.
Then there are those who treat our species like a special little snowflake in the universe. That somehow being sentient with a consciousness is intrinsically deserving of cheating death - self-righteousness at the species level. That science can solve any problem, and not only will it be possible, but that it unequivocally should be done. "I think, therefore I am, and should forever be".
tldr; Death is, at least presently, inevitable. Get over it.
