Our amazing bodies are able to heal themselves. If we could see the inside of our bodies, we would see cells dividing and the internal workings that help our body to heal itself. We have neurons that let the brain know when there is damage in the body. If we end up with a cut on our body, the body jumps into action to stop the bleeding and to heal the area. The body needs rest, exercise, and nutrition. When we give it what it needs, it can function at the greatest capacity.
