Why do people stop growing taller?

Kids grow super fast and get taller and taller and taller and then – all of the sudden they stop! How do our bodies know when it’s time to stop? Why don’t we just keep growing until we reach the sky? We asked Dr. Frank Rhame to help us find the answer. Got a question that you think is a tall order? Send it to us at BrainsOn.org/contact, and we’ll answer it shortly.
