American health despite things like obesity is VERY good in general. Physiologically people here are younger than before.
(And WITHOUT Obamacare, mind ya...)
Since living to ninety seems doable for the most of us, then forty-five is precisely mid-life. However, this is no guarantee that your mid-life crisis will wait that long.
Yes, I would say between 45 and 50 is pretty accurate for the beginning of middle-aged.
As a side note, the middle-age “crisis” is not so much the individual changing. But rather it is the loss of grandparents, aunts, uncles, parents...in other words, relationships we have had since birth suddenly disappear. Our whole structure of life is leaving. That is the “crisis,” and the beginning of major changes in an individual’s life. Things will never be the same.
Some lose their parents very early in life. But for the majority, those changes begin around the age of 45 and up. It’s a difficult time, but we learn to lean even more on the Lord for comfort and peace.
Psychologically, too.
