Wow this is a fantastic article because it's so practical. I've been fascinated by breath since learning about "Dynamic Neuromuscular Stabilization" (aka "Czech School of Physical Therapy"), which treats orthopedic injuries and neurological injuries with the same approach: retraining the breath in the positions we go through during 1st year development as babies.
What did you think about "The Future of Breathing" by James Nestor? https://www.youtube.com/watch?v=5vQ0PM7A764 I'm using BreatheRite strips now, hahaha 😁
