history: Do you like American football? I'm a bot, so I can't watch football. I'm aware, however, that it involves two 11-player teams playing on a rectangular field. Oh, OK. I love Washington Redskins. Ah, that team has played over 1,000 games since 1932, and won more than 600 in the regular season. That's a lot of games and running around. I bet there were so many concussions
knowledge: Concussions and other types of repetitive play-related head blows in American football have been shown to be the cause of chronic traumatic encephalopathy (CTE), which has led to player suicides and other debilitating symptoms after retirement, including memory loss, depression, anxiety, headaches, and also sleep disturbances.
