‘One of my first self-defence teachers told me that I shouldn’t bother with any technique that I couldn’t learn in five minutes,’ I said. ‘Idea is, if you can make it work in five minutes, then practising will make it better. If you can’t make it work in five minutes, then you probably won’t be able to make it work in a high-stress situation. When your life’s at stake you want something that works every time. Simple is good.’
