The term “middle-aged” is a little awkward, because it’s a tactful euphemism for an older group than it seems to describe. If the typical U.S. human life is, say, 78 years long, then age 39 should be solidly middle-aged—but that’s not what we mean by the term. We actually mean something more like “well past the middle, but the term elderly isn’t right yet.”
I think of middle-aged people as being in their 50s or 60s or so—but it’s a stage of life more than an exact age. It’s a stage with no young kids in the house anymore (unless it’s grandkids), but no need yet for walkers, or for those chairs that help a person stand up. When a middle-aged person gets sick, we don’t think, “Uh oh, hope it doesn’t go to the lungs.” We don’t worry much yet about broken hips, but there are plenty of lost bifocals. No one is talking about whether it’s time to take away a driver’s license or “think about a home,” but there is talk about retirement. There are of course myriad exceptions (a guy in his twenties might have bifocals or have bad lungs or need to use a walker; a guy in his 60s could have little kids with his young wife), but middle-aged is a general term, so I’m speaking of the group it describes in a general way too.
I have a new proposal for terms. I was thinking about how middle-aged doesn’t describe the middle stage of life: it’s more like the third out of four (childhood, adult, middle-aged, elderly). Then I noticed another euphemism for age, which is the “senior” in “senior discount” and “senior citizen” and “seniors residence.” And the combination of “four stages” plus “senior” made me think of how we mark high school and college grades: freshman, sophomore, junior, senior.
We’re currently using senior discount to include people over 65 or even 60 or 55, so we’d have to change that. “Senior” would now be used the way we use “elderly”: deep wrinkles, white hair, fear of broken hips, nursing homes, walkers. Then we could use “junior” to cover the category we now call “middle-aged”: bifocals, falling necks, kids are grown, menopause, needlework about having the fun grandchildren first. Early/mid-twenties (depending on personal maturity rates) up to middle-aged would be called sophomores. And children up to their early/mid twenties would be freshmen.
If we’re going to use euphemisms, it’s nice to have them TIDY. And I also like the way this system automatically implies a gaining of knowledge and experience, rather than an increasing fumbling with new technology and change purses.
