How does happiness affect a person's overall health?

Happy/Normal: A way of thinking about happiness or normalcy is a range of behaviors for instance if you were to wash your hands one or two times a day, typically that would not be considered abnormal. However, if you were to wash your hands dozens of times per day, that quite likely would be considered abnormal. In this context normalcy should not be thought of in simple terms of yes or no, black or white.
