The impact that concussions have on people cannot be understated or understood by people who haven't experienced them. I understand what he means when he says his brain felt "mushed together" and that he was whipping his body back and forth trying to shake the pain out. I have had 5 documented concussions and have had that same experience. I have long understood why Junior Seau took his own life because living with that on a daily basis would not be possible. I haven't had symptoms for a decade, but I do fear that returning later in my life.
