Am i still growing? my fellow 20-21 year old friends and i hang out and recently i've noticed 2 of them have gotten a little taller. what's happening?

Unlikely to happen: Some kids continue to grow taller into their late teens or rarely early twenties but only when their bone maturity lags behind their age. If the growth centers of the long bones have fused, you cannot grow taller. A single x-ray of the wrist ; hand can gauge bone maturity.Most boys stop at 17. When you have reached bony maturity, you are done.Your friends may be wearing platform shoes.
