@parus Hi there. I used to go a Tai Chi class several times a week. Many of the members in it do suffer from chronic illnesses and swear rhat it helped them. We would begin each class with 'tapping'. It is said that is done to wake up your bone marrow, where new red blood cells are made. Then, we would cultivate the energy around us and in us to fortify our 'chi' which is our life force. I could def feel the collective energy amoung us. And I did feel better for it. If you get a chance to participate in a group, you might consider it. Our group is free and usually in the park. But, I want to add that you do not need to be in a group to do it. You can probably find it on Youtube and learn to do it.
