Your brain is much more highly developed than that of animals. You have the ability to use your mind to think, make decisions, and practice self-control. Simply stated this means that your body runs by a set of rules built in by its Designer. Observing the laws of health is not a question of sacrifice, it is just a good, common sense route to feeling better and living longer. The rules of health say, "That which strengthens and builds up health and happiness is right. That which weakens and destroys life and health is wrong."
Your minds and the body are very closely related. You are what you think. Fear, worry, anger, depression all interfere with good health, and may even produce disease. Likewise, happiness, pleasure in a job well done, and enjoyment react together to help your body function as it should.
But body and mind do not make up the total of your life experiences. You are in contact with people. Your social life would not be complete without your family, your friends, your relatives, and neighbors. Man was not meant to live alone. We were meant to share our experiences of life with others-to be concerned about our neighbor. We are all of one blood on this planet earth. Our feelings toward others are important to our own well being.
