The reason I took this section out of my book Create Your Own World By Natural Healing is that the main reason for corona is that there is too little oxygen in the blood. When stress takes to long and becomes chronic, we must actively take control to avoid psychical pain or illness. Controlling the breath is the key to our psychical and mental health. Stress and emotional stimuli that shorten the breath ensure that too few antibodies are produced by the body that remove waste products and viruses from the body. Sanquin blood care in Rotterdam already discovered this, that people make new cels in good lungs with anti cels against this virus.
