Everyone breathes... but few of us breathe well. Breathing is one of the most natural things we do. However, it is estimated that more than ⅓ of people do not breathe well enough to maintain normal levels of health. All of our cells are dependent on oxygen. Often we are not breathing well and our cells receive only enough oxygen to stay alive. When you do not breathe deep enough, you do not receive enough oxygen and you do not release enough carbon dioxide from your system.
