The other day I was in a class and we started watching the Will Smith movie “Concussion”. Everyone in the class was kind of half paying attention but I saw enough to realize why some NFL Football players are retiring early. Some of these players had very similar side-effects to the PTSD that soldiers get. Some players were seen getting violent and abusive with their families and one player even got into his car and drove into on-coming traffic and killed himself and the person (or people) in the car he hit. Also, many of them were former linemen; coincidence? I think not, due to how much contact is involved with being a lineman. It is much more understandable that these players have shortened their careers because in the end it may end up killing them.
