32 isn’t that old. I mean, Millenials are in their 30s now so that’s just basic adult age.
“Young adult” is basically late teens to early twenties. So if 32 is “old”, then the only adults are 25-30.
I’m probably overthinking this, but even the art depicts normal adults. Personally I think “old” as when the body starts acting up, like when hair starts to get white and eyesight gets worse and etc.
