This is current bedside reading. It’s about fighting in ice hockey. It’s an odd thing, ice hockey is the only team sport where fighting is allowed, but there is a very strict code about it. The book isn’t really glorifying fighting but exploring the code and how some people view it as a positive (the argument is that knowing if you mess with someone the enforcer will get you, stops dirty play), but also lists the injuries and damage it causes.
There is a Cardiff Devil supporter, [url=http://cardiff.academia.edu/VictoriaSilverwood]Victoria Silverwood[/url] who did a PhD in this concept of legitimised violence. She’s publishing a book on it soon, which will be an interesting accompaniment to this.
