On a sunny afternoon, a teenage boy was practicing on a massive wooden skateboard ramp in his driveway. He flew high into the air, executing a trick, but lost his balance on the way down, crashing violently onto the concrete. He lay completely still, groaning in pain. The family dog rushed over, licking his face anxiously. Hearing the crash, his mother ran out of the front door screaming his name in absolute terror. The father knelt down beside his son, checking his responsiveness. “Follow me with your eyes. Can you hear me right now?” he asked urgently, his face inches from his son’s dazed expression.
