A human hand has 27 small bones, including eight pebbleshaped bones in the wrist, laced together by a network of ligaments, dozens of tiny muscles to move the joints. Scientists have noted that there are more nerve connections between the hands and the brain than between any other parts of the body, and so the gestures and positions we take with our hands give powerful insights into our emotional state. Because our hands are usually in front of our body, these signals are easy to see and most of us have several trademark hand positions we continually use.
