Grabbed the rim of the single basketball hoop at Eisenhower middle school during lunch and, in slow motion, felt the rim slipping from the tips of my fingers that were holding on for dear life as my momentum sent me flying horizontally back down to earth, knocking the wind out of myself as everyone watched. The subsequent walk to next period with my arm draped over my buddy who was carrying half of my body weight as the feeling in one of my legs was gone was a doozy. I still don't know whether or not I experienced a concussion on that fateful day.
