Personal experience from bouncing. Yeah, there were giant buff monsters kicking ass. But do you know who 90% of the people fighting were? Just random assholes who got some alcohol in them and decided they needed to start throwing punches. And their punches were as dangerous as you would expect. That's amazing! You go into a bar of physically dangerous people and you might be endangered physically? Fucking unreal. We've got to give you some kind of scientific prize. You must agree that if you go into a bar full of average people you're likely to see average people fighting without skill. And I can tell you from personal experience the number of physical beasts getting into drunken brawls are not disproportinately higher than anyone else. Learn how to punch, learn how to kick, practise those things and you'll have an advantage over a random asshole on the street. I don't know how you can deny that.
