Who would have guessed that getting your brain damaged constantly makes you into a punchy asshole just like everyone else who gets brain damage recreationally instead of for money.
I wouldn’t speculate about brain damage being a factor.
I would speculate it’s more about the type of person who solves all their problems with violence.
¿Por que no los dos?
There’s a very clear corelation between frontal lobe damage and disinhibition of violent impulses.
This goes all the way back to Phineas Gage.
Although I also agree that MMA fighters are also generally self-selected to be egregious assholes.
