There's speculation that an American UFC fighter by the name of Mackenzie Dern puts on an accent and deliberately speaks poor English. What do you think? Her English seems pretty poor for somebody that was schooled in the US.
It did make me curious if the fighters who have been shown to suffer effects of too many punches showed similar changes. I recall a lecture by a psychiatrist during grand rounds teaching medical students about the effects on the brain of boxing--- he told them (while I was also in the audience) that during a fight with blows to the head the brain is suspended in fluid and bounces back and forth against the skull causing a lot of damage that is not quite like a single concussion and can lead to significant changes.
I remember him using Mohammed Ali as an example so I went to search for stuides on Mohammed Ali. http://www.espn.com/boxing/story/_/id/20420022/muhammad-ali-speech-study-reveals-early-indications-parkinson-disease
This article indicates he had changes as early as 1978. I also found this quote interesting:
In May, the ASU researchers also released a study comparing the language usage over eight years of 10 NFL players -- seven of whom were quarterbacks -- with those of 18 NFL executives and coaches who had never played professionally. The players, according to the study's findings, were significantly more likely to show signs of deterioration in their vocabulary and sentence complexity
I guess it is possible that her speech is deteriorating in sentence complexity as well. I think there is very little data on whether female brains are more susceptible to the damage from head blows than male fighters as I think females fighting so frequently is a relatively new phenomenon in sports.
"I find it hard to believe you can be born, raised, and educated in the US and come across like that."
This is is not exactly the same thing but it's common for some northerners like me move to a southern state and start speaking in the local southern manner in which one lives.
But yeah, I'm with you on why she's doing it.
