I have had several discussions over the last few years about when "middle age" truly begins. My initial argument was that a person living in the U.S. these days could reasonbly expect to live to 90, if they take care of themselves. If you divide 90 by three, you get 30. So the first third of your life is zero to 30. The second, or "middle" third is 31-60, and the final third is 61-90. Most everybody I've run this theory by has said 30 is too young to be considered "middle aged". And I now believe they're right.
Middle aged is now defined as when you receive your invitation to your high school's 20th year class reunion. Mine came yesterday. I shall wear the bottoms of my trousers rolled.
