It's a famous unwritten rule in sports that you're supposed to avoid sex in the days leading up to a game or, in the case of a boxer, a fight. Well, it turns out that one notable fighter is not a believer in that rule. The fantastic and intelligent and funny and inspiring and totally crush-worthy Ronda Rousey. No, the current baddest motherfucker in the United States (an unofficial but impressive and deserved title) was on Jim Rome's Showtime show a few years ago, and she revealed her dissenting opinion on the matter.

I mean for girls it raises your testosterone, so I try to have as much sex as possible before a fight, actually. (Laughs) Not with like everybody. I don't put out Craigslist ads or anything, but you know, if I got a steady, I'm going to be like, “Yo. Fight time's coming up.”

You can watch her whole answer here, where she also addresses how abstaining for guys may also be a bad idea testosterone-wise.

Interesting. So instead of taking a dumb old sports superstition at face value, Ronda Rousey uses science to prepare for a match. And how has that gone for her? Oh, she's undefeated in her six fights since that interview and has only gone past the first round once? Okay, cool.
