Downvotes to your post are unwarranted. Western medical school tends to think that pulmonary fibrosis is incurable, despite the fact you have just provided a practical recipe for post-pneumonia rehabilitation.

This is what I call a comfortable ignorance. Kudos for finding the practical way out of this situation.
