Obviously teenager is 13-19.
“Young adult” would start at 20, but where’s the cutoff at the upper end? Similarly, what’s the range for “adult”, “old”, “elderly”, " ancient"?
If someone asks for responses from “old men”, how do I know if it applies to me?
Yup. I substitute teach at a middle school and a couple years ago, I heard a 12yo say 40 would be a good age to die because you’d pretty much done everything you could by then… I’d just turned 40 a few weeks earlier.
