The vast majority of aggression is something much more often than not related to blood pressure. As blood pressure rises you become more tense and then on edge and all of a sudden you cant handle things from a stress stanpoint the way you normally could. When using test your cardio machines are your best friend. Not only do they increase your cardio function and blood gases ,health in general , they decrease the blood pressure and the effects of the so called rage. If using gear you need to purchase a blood pressure monitor. If you will increase the number of cardio sessions wbhile on gear and then slowly increase the amount of time per session, even if splitting it to morning and evening, you will notice a profound effect on your "rage". I keep mine well under control and will ven hop on the home climber at night if I feel it popping up on me. The instant effect increases size in vascularity and lowers bp...same am.ount of water running through the hose is less pressure when the hose siz is larger.....cardio is the deal, keep yourself healthy, thats what we are all about right.
