Cos folk love to read it. I know guys on doors that read nothing but that shit and crime lords n such blah blah blah. 'Yeah, so i just smacked this clown with a right yeah and he hit the deck, his blood was everywhere, I thought he was dead' or something like that. What a way to live eh. Not that this cant happen by proxy(or maybe through need), in your everyday life aswell.
Not read many, in fact iv made it through 2. One had some funny short stories but a lot of blah. Other one was Geoff Thompsons 'watch my back'. Think i still have a copy. Good book.
