I remember Ron Tinsdale (?) was very dubious about some things I said about previous confrontations I've had (particularly cos I'm quite small and had some confrontations with people almost double my weight). However it is because of the psychology of response which gave me a massive advantage. I was able to respond without having to 'worry' about combat - it just happened. I couldn't have planned a repsonse (it was completely subconcious), but I did train just to respond - by doing aikido.
