 This is your first book, I believe, The Code of the Warrior. And I know you've got another one which we can talk about in a little bit. But you go back and you talk about the history of these codes of conduct, all the way back to the Greeks and even the Vikings and the Romans and things. And I was wondering if you could kind of talk a little bit about the derivation of that and where that came from, when we decided to fight by the rules.
