Living Forever

You captured the sense of boredom well. I can't improve upon that.

I'll add to it a sense of hopelessness. I think as frightening as death is to us, our enduring sense of hope is tied up in it. Remove the prospect of death and you remove the underpinnings of hope. The thought of it is truly depressing. It's like imaging eternal life with no heaven or hell. I remember long ago being truly frightened by the notion of "waking up" after death and having to spend forever in a coffin. The sense of boredom is there for sure; the sense of hopelessness is crushing.
