Death isn’t really the opposite of life. It’s what happens at the end of life, it’s a stage us living beings go through. If you look at it that way, it’s much less scary.
Of course, yes, death is the opposite of life, but hopefully you see what I mean. I’m more scared of missing out on stuff than death, really. Like, if I died before Episode III came out, well that would have sucked. Or, if I die before I read the final Harry Potter book, well that would suck, too.
