Our society has, as part of its democratic values, taken on the responsibility for extending life as long as possible, often at great cost. And many procedures, such as open heart surgery or coronary bypass, can be given at later ages than before, with reasonable results (sometimes ten or more additional years of survival, well into the 90s, and reasonable independence for some years), were not possible for earlier generations. Periods of senior disability at end of life are longer than they were for our parents when they tended our grandparents.
I must add something else here of a personal nature. I don't liked to be asked to function as a "role model" for kids in situations resembling those that were humiliating when I was a boy. (But I guess that really belongs on the main blog.)
