401- CHRONOLOGICAL AGE VERSUS FUNCTIONAL AGE?.....

I'm not sure that "versus" is a proper usage of the comparison of the two concepts!
"Chronological age" is the actual numerical number attached to the birth year. "Functional age" is how one thinks and interacts both physically and mentally, period!
This researcher sees more and more generational gaps between the "young" and the "older" groups within our American society!! The way the "older" are treated in hospitals, dining, driving, medical care and even reunions when both age groups, broadly speaking, interact is this sociologist's main ponderable!
a) WHY is the chronological age usually brought up in so many ways? American society seems to have a fixation with "How OLD are you?" It's none of THEIR freaking business, period!
b) I remember, vididly, being seriously ill, in a hospital, six years ago. Someone came around one morning and closed all of the doors on the floor. When I asked 'why', no one would say why! Later, it slipped that someone had died, and closing the doors would shut out what really had happened to everyone else. Well, now, this guy did come back to good health, with pure grit and PMP..."positive mental power."
