Healing
Our body is a super amazing machine in this universe that can fix itself. It can clear away dirt and germs and grow new skin when we got skin damages or wounds, muscles, or bone to repair an injury. Of course, a little sympathy helps, too.
Cells near a wound grow and work to replace damaged cells. First they make a quick repair. Then they work more slowly to make the injured place look as good as new. They cannot always make it look exactly as it did before it was hurt. A bad wound may leave scars.
