My height is 6feet and I am only 16 , what should I do to stop growing

Hello Anon

Thank you for writing.
Are you male or female?
A boy of 16 will likely stop growing by the time he is 17. At 6 feet tall, you are of average -to-tall height. In other words, if you are male, you are not particularly tall.
Height is mainly determined by genetics and can be affected by diet and lifestyle.
