An older thread, but I don't sign in too often.
As a physician, I've seen people die of many different problems. It seems like we will most likely pass from cardiovascular disease (heart/stroke), cancer, or mental deterioration. Unless you have a strong family history for one of the above, it's a crap shoot. I've always tried to follow the philosophy "everything, in moderation". In my 70s now, and waiting for the shoe to drop. Enjoying good health (while it lasts).
Congratulations on the good outcome from the prostate CA.
