Two of the most infamous cases of CTE-related NFL deaths came in the suicides of Dave Duerson and Junior Seau. Both Pro Bowl players shot themselves in the chest to preserve their brains for research purposes. Duerson complained of his deteriorating mental state during the final months of his life. Seau suffered from insomnia for the last seven years of his life, and the lyrics to the song “Who I Ain’t,” a song about a man who regretted the person he has become, were found on the kitchen table of his home after his suicide. Both players were later confirmed to suffer from CTE by neurologists at Boston University and the NIH.
