Someone says that if you play basketball or something like that, your lenght will grow up. Indeed, I don't believe this. By the way, I wanted to take your ideas. What do you think about it?
A person's overall height is determined by their genetics. You can stunt a person's growth by malnutrition, but a person can not grow taller than what he or she is destined to be.
The reason people may think sports make people taller is because professional athletes tend to be taller than average. That is because height gives a slight advantage in some sports. It has nothing to do with any kind of extended growth.
