I've definitely fell off mine as a kid but I feel like these stats have gone astray from what they Used to be used for... At one time they were told to us along with the changes that were being made to an unsafe product. Now they give us these numbers as scare tactics. Kids are actively and get bumps, bruises and sometimes breaks.... It a natural part of learning how to move around and what your body is capable of. Life is being designed to put us right into a chair with straps and keep us there making us physically weak through fear based inactivity
