When leaving a local newsagent I was stopped by a man who reached out and shook my hand casually asking how I was and smiling, to look less suspicious to other people around. He then asked me to hand over any money I had. I had just put my money away in my bag. On automatic pilot, I performed the self defence movement for the handshake I learned recently which involves twisting the wrist and thrusting down. This then caused him to fall to the floor. He then walked away. Without learning this movement in one of the self-defence aspects of the Martial Arts training sessions I attend, I could have been in much more trouble!
