This is the text (if you need help).
Doctors warned that headbanging could be bad for you. Headbanging is a dance that fans of heavy metal music like. People quickly shake their heads backwards and forwards. Doctors say this could injure the brain. They recently saw a heavy metal fan who had brain damage. He had no history of head injuries and had been headbanging for many years. Doctors said the risk of brain damage from headbanging was low.
The man had bad headaches after going to a concert. He had a brain scan. Doctors found bleeding in his brain. He had an operation to repair it. Doctors made a hole in his brain to release the blood. His headaches disappeared. A doctor said: "The risk of injury is very, very low. If our patient had gone to a classical concert, this would not have happened." He said people should dance and that: "Rock 'n' roll will never die. Heavy metal fans should rock on.”
