That's been my experience everytime I bring it up in conversation. Hell, I don't even really care about living forever, but if I can live however long I'm alive without becoming old and decrepit I want that.People always seem to have negative reactions to the idea of immortality, and I've never understood it.
I forget the name of it, but there's a short story about a world where everyone gets eaten by a dragon when they reach a certain age. No one can defeat the dragon so they accept it. As the centuries go by, and technology advances, some people realise they might be able to kill the dragon. Most people think the idea is ridiculous, that you shouldn't mess with the natural order, so there is no funding for dragon killing projects. Eventually the monarchy does fund the dragon killing project, and when it's dead they are wracked with guilt over all the generations that died needlessly.
I think we're currently in the "insufficient funding for dragon killing projects" phase.
There's definitely a sense of pessimistic acceptance regarding old age and death ingrained in human society in general. Hard to know if we'll ever get passed that.
