So, I’d massed bunches of hair into two rough ponytails and then scrolled them round and tucked them in a sort of thick knot that sat on either side of my head. I’m not saying it is a good look, but as far as shock absorbers go, it is the best hairstyle you could hope for. When Karl smacked me in the head, the hair had soaked up enough of the blow to simply render me momentarily senseless rather than knock me out cold.
