The other day I accidentally cut deeply into my index finger. After the heavy bleeding had stopped I was left with a gaping cut that hurt for two days. But soon after the wound started to close and to heal. It always amazes me how the body “remembers” what cells to grow when healing a wound. It’s a miracle to me. After just one week the cut is completely closed and pain free. How does the body do that? Engineering hasn’t managed anything as remarkable as the self healing capabilities of our bodies.
