“A heart that is joyful does good as a curer.”​—PROVERBS 17:22.

Similar positive effects spring from a joyful heart. Dr. Derek Cox, a health official in Scotland, stated in a BBC News report: “If you are happy you are likely in the future to have less in the way of physical illness than those who are unhappy.” The same report stated: “Happier people also have greater protection against things like heart disease and stroke.”
