This may come as a shock, but in the US healthcare system, surgery and hospital stays are tens of thousands of dollars - per day.
If she gets wrecked and needs stitches and a hospital stay, whatever her paycheck says will look a lot smaller after she gets her hospital bill.
And then you figure the money she'll lose after getting her attractive face all cut up and becomes unmarketable...
I just don't get it. If she really likes to fight, okay, fine. But she seems to do it more as a way to get her name out there and then profits from her beauty.
If she loses her beauty, she's ultimately losing money in the long run, no?
