https://en.wikipedia.org/wiki/Chronic_traumatic_encephalopathy https://en.wikipedia.org/wiki/Traumatic_brain_injury https://en.wikipedia.org/wiki/Acquired_brain_injury Wikipedia has some very interesting summaries on brain injuries. The introductory section for Acquired Brain Injury has one of the most oversimplified summaries as to why this stuff can be so scary . . .While research has demonstrated that thinking and behavior may be altered in virtually all forms of ABI, brain injury is itself a very complex phenomenon having dramatically varied effects. No two persons can expect the same outcome or resulting difficulties. The brain controls every part of human life: physical, intellectual, behavioral, social and emotional. When the brain is damaged, some part of a person's life will be adversely affected.
It makes me wonder about a lot of shit. Kind of makes me wonder if we're taking the first steps into a whole new world of psychology and pathology. Kind of makes me wonder if all those people who had bike accidents, fist fights, football games, etc. as a normal part of growing up would turn out different. Someone told me that there was a direct correlation between removing lead from gasoline and a drop in violent crime (was that you?). Makes me think about sports differently.
