To relate this to the news about CTE in American Football, I wonder how much American mental potential has been lost to CTE. One thing for sure, very few East Asian and few Asian American parents who are aware of the news will allow their kids to play the sport. What about the reactions from other American parents? "Symptoms of CTE, which occur in four stages, generally appear 8 to 10 years after an athlete experiences repetitive mild traumatic brain injury." There were about 1,100,000 million high school players in 2014. This is approximately 7% of US high school students. https://en.wikipedia.org/wiki/Chronic_traumatic_encephalopathy#American_football https://en.wikipedia.org/wiki/Chronic_traumatic_encephalopat...
