Yes, about the breathing. I listened on the radio years ago, coast-to-coast. A women wrote a book on breathing techniques. One was to breath through your nose and out your nose. And she said, breath like this and it is like how you breath when you say a rosary/Hail Mary.
She stated that breathing techniques can help a person out of a wheel chair to walk. We also know that praying the rosary can lower blood pressure.
