Why is dunking harmful to health?

Dunk is not harmful to the body, but more dunks are harmful to the body, which is very harmful to the periosteum of all joints of the body, especially the periosteum of the knee joint. Every burst of strength is a heavy pressure on the periosteum. Over time, the periosteum was seriously damaged. Young people like to deduct NBA players, and they have to rely on crutches when they are 50+ years old, so they should deduct less maintenance fees.
