I don´t talk about the street. But about domestic violence. Look at how many boxers are known to have beaten their wifes. I think in an argument a boxer may slip a hand, like we in Bavaria say, easier than your average Joe.
It's actually been proven they're more likely to. Ultra high levels of testosterone from them being athletes among other things make them among the most aggressive men out there.
Classic example: Ike Ibeabuchi holding a stripper hostage, nearly going beserk in a cafe about his championship that he never won, and leaving a child disabled after a car crash.
Proven by who? As it happens, I live in Spain where there is a problem with domestic violence. I very much doubt that it's because all the Spanish men are bulging with testosterone. I would suggest that it is more likely due to ignorance and control.
LOL. Second time you asked and second time I'm giving you an answer. He's this chap.... http://www.sandowmuseum.com/page41.html
