Laughter is indeed a great medicine, which many clinical studies have revealed.  The key is where true laughter comes from, and how to make someone laugh from his or her heart. Our medical system, while capable of great feats, is certainly not advanced at promoting laughter and joy. One easy evidence is from our be loved laughter star Robin Williams. He made us happy but not himself. So how can we enrich our lives with true laughter from the bottom of our hearts? Please send your thoughts. Thank you very much!
