When you read about a celebrity dying at 94, are you sad that he died, or happy that he made it to 94?

I'll just quote John Dunn ..
Every persons death diminishes me ...
... On a personal level though it's the quality of the life lived and not its length

After you pass the age of 70 or so there is very little happiness. My mother was happy at 90, hoping to live two more years so she could be the oldest in both families. She lived almost to 99, but there was no more happiness because she couldn't drive, or sew, or read, and Lawrence Welk was the only show on tv that she could tolerate.

A little of both.

It depends on the person and what I feel that person wanted.  Not my call.

It depends on their health. In my experience, most older people have poor health and a deteriorating quality of life.
