Book excerpt: With few exceptions, the human body is a self-healing organism that would function perfectly when given the things it needs, such as nutrition, exercise, and social and spiritual food. Most of the time, however, life gets in the way. The good news is that everyone has the chance to make right with physical, emotional, and spiritual needs and to live in a way that allows the body to function better. For those headed in the wrong direction, inaction is a choice. Reversing downward spirals to get life back on track requires each person to make a choice to live differently.
