>Dementia Pugilistica, or “Punch Drunk” syndrome was described by Harrison Martland back in 1928, but the disease was confined to boxers for roughly 80 years, until the first cases of Chronic Traumatic Encephalopathy among professional American football players were described.
>Risk of CTE was higher with more years of football playing and with playing at a higher level. 110 of 111 – that's 99% - of former NFL players had CTE.
>86% of these individuals had memory problems, 72% had dementia in their last year of life, 91% had behavioral or mood symptoms, 68% had motor symptoms.
So that's why Americans are dumb, they play their barbaric """sport""" too much.
Boxing started in England though, and it's popular now worldwide.

That's about American football, though.
