random shit? It is a biological fact where did you read that height can still increase after 20?
after 18* Also, just look up the height of your favourite athletes when they were 18 and now, chances are, a lot of them grew taller way past 20. Even Ronaldo was 5'10" at 18, and now he's 6'2". Scott McTominay was 5'6" at 18, and he's 6'2"+ now. Scottie Pipen was 6'1" at 18, now he's 6'8". It's common knowledge that men grow way past their teens. Atleast until 21.
