I agree that we should be very vigilant.In self defense, if I was attacked or faced with impending doom I would target the throat, groin, and eyes. One needs to stop the attacker immediately.I have an amazing book by Shoji Nishio, the late aikido master. He writes about about the importance of budo applied to all techniques!!!!!One getting into an opponents dead space ( blind spot) using half steps and and tenkan movements. An example would be applying ikkyo ( arm pin). My primary martial art is Iwama aikido. This style of aikido uses atemi (strikes), so shotokan compliments this really well. I really enjoy the one steps and katas!!!!!!!
