A rock climber recovering in hospital after being struck on the head by a “microwave-sized” boulder has credited his helmet with saving his life. Boehm plummeted to the ground, breaking his collarbone, collapsing his lung, and breaking seven ribs upon hitting the floor. The experienced climber was also left with a large laceration on his back where the rock had sliced him after hitting his head. “I definitely knew my right side was broke,” Boehm told local news. “Your helmet will save your life no matter what,” Boehm told KTVQ whilst recovering in the hospital.
