The whole point of calling somebody “middle-aged” is that they’re in that indeterminate space where they definitely aren’t young anymore, but they aren’t like, old, old, yet, basically they’re still able-bodied enough to hold down a job.
Not one. Not the other. Somewhere in the middle. Middle-aged.
30 isn’t so old, but it depends hard on the person in question, some are still in great shape, but many 30-year-olds have been nursing a back problem and/or jacked knees for years by the time the birthday comes, they sure as hell don’t feel young. Some 30s haven’t had kids yet, some of them have kids in middle school. So that averages out, and we onboard you to this shitty party at 30. If you can still rock the swimwear at 30, do it, and don’t take it for granted.
For the record, we don’t care what children think old is. Children are insane.
