I think many people are not terrified, or even particularly afraid. I certainly don't want to die (like, ever), but I can understand those who "are ready" to die, now. Ten years ago, I couldn't even understand that. It was incomprehensible to me.

Generalizing improperly from my own experience and that of people I know, it seems to me that it gets easier to accept the idea of death for many people as they age. Hopefully we'll crack the aging thing ASAP, but I wonder how many will die of old age even after aging is more-or-less optional.
