Sometimes difficulty of breathing is due, not to
anything wrong with lungs or windpipe, but to failure in the diaphragm
(or large muscular "floor" of the chest), and the other chest muscles,
which work the lungs. A feeling of sinking and weakness round the waist
indicates in such a case diaphragm failure. Gentle heat at the small of
the back, and olive oil rubbing, form treatment for this. For other
chest muscles, give a warm washing each night with SOAP (see) over
the body, and rub, especially the back and chest, with hot olive oil.
You soon bring the muscles into good trim.
