How can I check my own Breathing pattern?

A very simple test can show you whether you are breathing as nature intended. Sit up straight in your chair (or lie flat on the floor or on a bed) and place your right hand on your chest and your left hand on your abdomen. Then take several deep breaths IN through the nose. If your left hand moves more than your right, i.e., if your abdomen rises more than your chest, you are already breathing as nature intended. If your chest moves up and down with each breath, however, you are not breathing as nature intended. You will need to practice breathing abdominally. By applying some time and attention you will soon be all to get all the oxygen you need. It is time that will be extremely well invested.
