Breathing can come from many directions. The stomach, the chest and the upper chest. To learn to use them with awareness place your hands on your stomach and breathe so you it remains calm. Do the same for the sides of the chest and the upper chest and move on to the next logical step. If you are alone you can use a heavy suitcase or simply take a broom, place the tip in the corner of the wall and lean your body using your chest or stomach on it to pressure this location. If you have a partner and you can ask a wife or friend to do this for you, have them stand on your stomach (do no harm) than place their knees on your chest or press the sides of the chest and than press on your upper chest and all this while you are to breathe through the openings or make one. You can do this statically at first and than move with freedom and press as you will. Enjoy your learning and smile. It relaxes the body. There is of course room to be angry at times as well. All emotions can serve you at one point or another.
