Well, e77, we're up there, I'm in the next decade. Now I do not fear the exit but worry about the way I might get there. Many suffer horribly getting there. Even in our "advanced" society that can be the case.
Often I think that HA presents itself as a cover for fear of the exit. If we can accept that everyone's fate is the same, as you say, we can get a handle on the HA, tell ourself we have today and make the best of it. Not easy. Requires constant attention.
