Here's what my friend had to say about Dr. Peebles' further comments about his high blood pressure:

"High blood pressure caused by tight joints and skeletal system: The doc told me this is one reason why he always says to "breath deeply into our spines." 

The rib cage should work much like an accordion he said, and it should be flexible.

He said my high blood pressure was partly due to constantly breathing too shallow and that tightness in my rib cage had developed.

Because he said, I have a big heart and it was constricting the pumping action creating higher than normal blood pressure.

He recommended that I visit a Chiropractor and I did this within two days of my reading. The doctor checked me out and without me even telling him anything about Dr. Peebles, he said my rib cage was tight.  He made an adjustment and I felt much better.

I bought a blood pressure machine at Walgreen's and that evening my blood pressure was 117 over 77 as compared to 145 over 97 earlier that day."

Pretty cool apples, eh?
