I do. Living for ever, or even much longer than our current life expectancy doesn't appeal to me at all. I like my life, but I also like that someday it will end. Back when I was religious (I'm not now) the idea of heaven or eternal life seemed strange to me as it was 'the goal' yet not something I wanted and the idea that I had to 'live forever' was quite worrying.
I'm curious if I'm in a minority on this. It's probably important to point out I don't want to die anytime soon but the idea that I continue living for longer than another 80 years for example is not appealing.
