If we examine the human body, we find it is more or less like a vast family of cells, all with their own special work to do. Some cells are bundled together in the form of powerful muscle. Others are hard at work in the nervous system, busy flashing messages her and there as needed by the body. Still others have the job of holding us together, and providing stability through our bones, joints, and sinews. On the surface of the brain we have certain cells that enable us to think and plan for the future. Everything we do, every reaction taking place within us, is carried out by one type of cell or another. This is life.

Just like the members of any good household, all these cells must be fed and cared of. How is this done? Through the things we eat and drink and in how we take care of ourselves. Eating and drinking, bathing and resting, all are vitally important to health.
