I agree that a long life is theoretically possible. I personally suspect that even if we overcome the body problems, neither human brains nor human minds will be able to cope with that, so that anything truly long-lived will be a post-human organism.

I also agree with you that the various theoretically possible techno-miracles likely won't mean much for us than a modestly longer old age. So I think everybody should really come to grips with what dying means. E.g., by filling out a living will and discussing end-of-life issues with family. If it turns out that preparation is wasted, I don't think anybody will complain too much.
