Have you ever been so mad you lost touch with yourself for a minute? "Anger is a highly physiological emotion," says clinical psychologist Dr. Joshua Klapow. "There are so many changes going on when we are angry that we literally become a different person — if only temporarily — if we are angry enough. Adrenalin rushes through our body causing us to feel strong and ready to act. We very much go from 'normal' to an 'Incredible Hulk' state."
