Batman takes a lot of blows to his head. These come from his fighting activities and from being routinely thrown—or leaping—onto or into hard objects like walls, floors, and moving vehicles. The issue of concussion in Batman’s career is something I addressed in Becoming Batman. In examining the scientific possibility of a human training to achieve the pinnacle of physical skill of comic book icon Batman, I reckoned him having a pretty short career. The main thing to shorten Batman’s career would be his accumulation of injuries, with concussion figuring prominently. In our own day and age concussion in sports—and particularly in hockey and football—has received considerable attention but little resolution.
