It's a common sight on Sunday afternoon. The snacks are gathered. The couch cushions are plumped. The beer is cold. Across the screen, twenty-two people in tight white pants and polished helmets trot across the screen. But behind the shiny exterior of football, America's favorite pastime, lies a dark secret - chronic traumatic encephalopathy (a word I am incapable of pronouncing). A neurodegenerative disease characterized by psychological, behavioral, and cognitive changes, CTE and repeated head trauma has been linked to rage behaviors and increased aggression. In fact, Aaron Hernandez, a former NFL player was posthumously diagnosed with advanced CTE, potentially providing a "why" for his brutal murder of Odin Llyod.
