"Those who think they have not time for bodily exercise will sooner or later have to find time for illness."
Edward Stanley, former prime minister of the United Kingdom
Moving your body is absolutely essential in order for the body and mind to function properly. Exercise not only nourishes your body with oxygen but it also feeds your brain through proprioception. Proprioception is the sense that indicates whether the body is moving with required effort, as well as where the various parts of the body are located in relation to each other. According to Dr. Roger Sperry, a Nobel Prize recipient for brain research, "Ninety percent of the stimulation and nutrition to the brain is generated by the movement of the spine." When you move your body and spine, this proprioception fires positive messages into the memory centers of you brain, your hormonal system is positively affected as well as your stress/anxiety centers.
