Concussion crash course

The prevalence of concussions and concern over head injury today has led to an explosion of interest about this subject matter. Athletic communities, war veterans, and parents alike are learning about the consequences of an impact to the head through news and media sources and are realizing the potential danger. This concern is well illustrated by the fact that the National Football League, an icon of popular culture in the United States, took action in 2010 and changed its rule book to include stipulations that disallow hits above the shoulders to “defenseless” players. Kickoffs are shorter now as well, giving both teams less time to gain momentum and smash into each other at frightening velocities. Action by such an institution indicates the serious nature of the matter.
