Of particular interest to me was the detailed information on how the beneficial chemicals are released into the brain when one goes for a walk. By allowing the opposite hand to swing forward with each step, left brain - right brain information is set flowing. This breaks up old patterns of worry and rumination.

Truth is integrity.
Your integrity begins with telling the truth to yourself, and with self-trust. Self-trust is trusting that you know your own truth, regardless of the options of others. When you say one thing and do another, you are out of integrity. Being out of integrity drains your energy. When you say you want to be healthier, for example, do one thing to enhance your health.
