Over the hill? The hill has moved

"Age is only a number," Yim cracked after his first glass of Shiraz. "But when you are 90, it is a real number."

I am moved to share some thoughts on aging with you, in case you happen to be getting older too.

What, after all, is old? To a child of 7, 10 is old; to my son who is 10, 25 is middle-aged and 45 is an archaeological exhibit. Although reaching 45 has not traumatized me, it has left me with disbelief about the flight of time. It seemed only yesterday I was 15 and old people were people in their 40's who were going someplace to sit down. Now I am doing the sitting.

Am I over the hill? Let me tell you: the hill has moved, people are younger than ever.
