I was bullied a lot for being short in high school and at home I was pressured to hang on the pull up bar "to get taller". I hope we stop doing this to people.
My experiences in high school deeply affected my mental health.
But on the topic of hanging, just out of curiosity, I'd like to mention: I've been reading about the benefits of dead hangs for shoulder health, and I've seen a few comments from people who claim that dead hangs actually did make them taller. I wonder whether it's true.
No idea about dead hangs specifically, but good posture (which requires strengthening the right muscles) probably adds a fair bit of height over bad posture, and bone can stretch slightly in response to exercise.
That said, the benefits of good health, better confidence, etc. from strength training probably far outweigh any benefits from increased height.
