Another problem faced in the self defence scenarios is the log jam. This is where the defender has learnt so many complex defences that their mind goes blank and they can't defend themselves effectively. This is also in addition to the loss of many fine motor movements, making many defences learnt in the class useless. One way around this is the KISS principle, Keep It Simple Stupid. What other ways do you have to over come this and give people the most effective defences? Budo.
