I only use a positive adrenaline switch if I
see a chink in the opponent's armour. This perception has
come from many years of dealing with violence and violent
people. If you can't read an opponent then I wouldn't
recommend employing this tactic, better to stick with
submissiveness and use it as a negative adrenaline switch.
I remember hearing a great story about one of the old
Japanese Sensie, Master Abbe, a world renowned martial
arts teacher.
