A comment on the comment.
Regarding putting off the inevitable. The mother of a very good friend of mine got cancer in her mouth. She was 92 y/o at the time. The doctor said they could make a radioactive dental plate which would give her two more years (of a slow death).
She replied, "So then I'll be 94 and still have mouth cancer. Nope."
Seems to be a quality of life issue. Many folks aren't interested in living a miserable life for the sake of living a miserable life. And it makes sense to me.
