Oh, one more thing Charis: the human heart is not in subjection to the brain (try to tell your heart to stop beating, you can’t). The heart regulates the circulatory system, the brain the nervous system. These two independent systems make a human life possible. If the heart stops, the brain will die within 10 minutes. If the brain stops working, the heart can still keep on beating for years (with life-support, since the lungs are dependent of the brain).
