It's Christmas, and John has an unexpectedly full hamper of yule tide logs to burn at the alter of meaning. First up is a review of Christmas Cozzi households present and past, followed by a Guns, Germs 'n Steel-style appraisal of the tribalism in Welsh Rugby. Next up is a journey into that most Christmassy of books, The Art of War. John wraps up with a reminder to keep things balanced.
