Stupendous arrogance in making assumptions; just because the body starts to denerate doesn't mean at all that guesses on his outlook follow. Even if one's feeling of well-being went down who's to say it wouldn't still be a great life-can you quantify how much diminution in well-being occurs later in life? Hardly!!
Anyone who uses the term "expert" especially about oneself is immediately suspect.
Pumpy, it is a fact that physical vitality decreases with age, and that degenerative diseases increase. My point is that it is harder to enjoy life when you have arthrites that makes all of your joints hurt, or diabetes that impedes you from enjoying an occasional slice of pizza, or dementia that makes you forget the names of your grandchildren, or gastrointerite that makes you lose control over your bowels, which causes a great deal of embarassment. It's not impossible to be happy with all these diseases; it is harder. Get it? I know a 96 year old woman who is completly demented and sometimes forgets her own name, yet she is always smiling and doesen't seem to care. She seems to be happy, although I suspect that she would be happier if her brain still functioned properly. As for me being an expert, well, I am. I studied this for years and then had to present a thesis to eight PhDs.
