On October 12, 2006, during a middle-school football game, 13-year old Zackery Lystedt made a hard tackle, slamming the back of his head into the ground. He walked off the field on his own, and later returned to play the second half. But just as the game ended, Zackery collapsed. He was airlifted to a Trauma 1 hospital in nearby Seattle, where he was in a coma for the next month. For nine months after, he was unable to move or even blink.
