All those knocks on the head he got on the football field couldn't have done much good for his memory. C-TBI is a serious thing. I work at a community college and see it often in the student athletes I serve. These poor guys have serious memory problems and we have to help them pass their classes so that they can keep playing. And for what?
Is it really lying if a person doesn't remember what they did or didn't do? Whether it is or not -- such an impairment would make things very easy if any higher-ups want to manipulate him. Scary stuff, folks!
