I looked it up, and supposedly "middle age" is
supposed to consist of the 3rd quarter of life.
Now that doesn't make a lick of sense!
The term "middle" doesn't mean "third out of four".
The term middle means second out of three (or, I suppose, 3rd out of 5)
As in, one on each side.
So, even if the official designation disagrees with
me, I still maintain that if there is a middle age, it should be in the middle;
equal parts between youth and elder.
Assuming that people tend to live to around 90, then it divides neatly up into
3 parts. Most people can agree that 0-30 qualifies as young, and that 60-90
constitutes old, yet no one I've talked to about it (and most especially those
approaching or just over the threshold) want to admit that 30-60 is in the
middle of those, and is therefor "middle aged".
While our society today is an exception, in most places in the world and in
most places in history a person would be married, have a kid or two, and most
likely a stable job or even a career and a house by 30, so that measure lines
up neatly with the math.
Unlike a lot of people, I don't expect to adjust my definitions as I get older.
I consider it a matter of integrity.
Besides, I am already heading that way by a number of personal measures as
well: I own the place I live in (granted, its only a trailer, but I did have to
pay off a bank loan before I got the title), I run my own business, I've not
only been married but I am already divorced, and while I used to imagine myself
as a human bullet as I raced down I-880 at 105 miles per hour in the middle of
the night, these days I drive the same motorcycle at 50 in order to get better
gas mileage.
If the middle third is what constitutes middle
aged, then I've got one year left of being "young".
