"We have all heard that laughter is the best medicine. The emotions that come from humor and laughter help people cope better with the stress of daily life. Studies have shown that people who laugh often live longer and are much healthier compared to those that find it difficult to laugh due to life's circumstances and personality types. This common reflex affects the body by activating the cardiovascular system, helps lower blood pressure and also exercises the muscles of the body. Research has shown that parts of the limbic system are involved in laughter as well. The limbic system is a primitive part of the brain that is involved in emotions and helps us with basic functions necessary for survival."
"...laughter can enhance the quality of our conversations and productivity and social interactions. It simply makes people feel closer to each other. ..'laughter is the oil in the social machine, helping human interactions run more smoothly'". (Physics and Consciousness)
