In the book Come Breathe With Us you will learn double nostril breathing, Mentalphysics Breathing Exercises and more. All and any of you who are reading this are currently breathing. It is not likely that our breathing patterns are the same. You can test for double nostril breathing very easily. Hold one nostril shut and take a breath. Now switch holding the other nostril shut and breathe. Is it the same? If not it's worth learning double nostril breathing. The course offers a set of breathing exercises with some degree of increasing difficulty with the guarantee of improvement in your health. You get more oxygen into your lungs and as a result into your blood cells and as a result better health. I am eighty years (old? young?) and do double nostril breathing all but automatically without any conscious effort. Having practiced all the breathing exercises in the course for over 2 years, the benefits for my health keep adding on. My posture has improved. My over-all stamina is back to where it was a decade ago. I sleep better. I've been active all my life, playing church-team hockey, swimming, hiking and such. Yet I know for certain that my entire body is more engaged in the MenthalPhysic exercises with greater benefits for my health. Everett Baker
