Now do this put-the-text-back-together activity.
This is the text (if you need help).
Doctors said headbanging could be bad for you. Heavy metal fans like headbanging. People shake their heads quickly. This could hurt the brain. A heavy metal fan had brain damage after headbanging for many years. He had no head injuries before. Doctors said headbanging wasn't very risky.
The man had headaches after a concert. He had a brain scan. His brain was bleeding. Doctors made a hole in his brain. The blood came out. His headaches disappeared. A doctor said this would not happen at a classical concert. He said people should dance, and that: "Rock 'n' roll will never die. Heavy metal fans should rock on."
Back to the headbanging lesson.
