Why do we stop growing around 20?

    Well, we stop growing because our genetic make up tells us to. Since birth we continue to grow and develop until our genetic growth cycle is complete. Think of it as a computer program that is programmed to stop growing at a certain time. You will find this program to be located in our DNA.

    I realize this answer may not seem sufficient, but this is what we know. Scientists have yet to discover why we have this genetic growth cycle or how exactly this program works.
