<p>Joe Bloke is obviously a pen-name. He spent ten years studying karate in his twenties and early thirties, and he used to teach karate classes. He draws upon that experience in writing this book (Self-Defence for Non-Experts: a book for people who can't fight) but he writes from the perspective of someone who is no longer quite so young as once he was and who therefore has to take a strictly realistic view of the dangerous business of being in a fight.</p>
