…happiness is what we feel when our biochemicals of emotion, the neuropeptides and their receptors, are open and flowing freely throughout the psychosomatic network, integrating and coordinating our systems, organs, and cells in a smooth and rhythmic movement. Health and happiness are often mentioned in the same breath, and maybe this is why: Physiology and emotions are inseparable. I believe that happiness is our natural state, that bliss is hardwired. Only when our systems get blocked, shut down, and disarrayed do we experience the mood disorders that add up to unhappiness in the extreme.
