Can a person(man) increase his height after the age of 21…?
Men usually STOP growing at the age of 21, so I have to say no, sorry! No matter what people tell you though, don’t try taking growth enhancement or anything like that cause it is NOT GOOD. The only thing you can really do is try to be happy with the height you are. I know this for a fact because I’m really tall, and I’ve always hated it, I’ve already accepted that I’m gonna be tall, so I live with it. But just try to accept the height you are, or if you want to, wear lifts in your shoes like the person above said!
