We blame the heart and never develop the lungs

We tend to blame the heart, because we never developed the lungs. When the ribcage is freed up, the lungs can pump the blood through the body and then the heart can just be an easy going valve.

(When I use the word “ lungs”, of course, this includes the primary and secondary respiratory musculature and the entire rib cage and spinal mobility.) 

The word “lungs” is used because that is the POV, the point of view, The lungs are the place where the attention rests. Where we place attention matters. We do these kinds of awareness experiments in the workshops.
