Lucha libre is stylized violence, just like pro wrestling. Ice hockey the contact is incidental; tackling is a foul in hockey. Rugby?
Football is to rugby as eating an entire raw pufferfish is to eating a California roll. Unless you choke on a splinter from your chopsticks, the probability of dying from your sushi is very slim. But, an uncooked pufferfish will for sure kill you.
I say this because, whereas F#$&ING 96 PERCENT of dead NFL players are reported to have CTE, in a 2013 BBC article, a neuropathologist with a great name, Dr. Willie Stewart, recorded, perhaps, the first ever confirmed case of CTE in a rugby player. As noted in the article, Stewart claims that “one or two” rugby players may develop CTE every year, and that it’s far more likely for American football players, who “suffer repeated head trauma and concussions,” to develop the condition.
Within five years, high schools will start going flag/touch football. Within ten, so will college. Mark my words.
