The world has never faced so much trouble before. People are within themselves about natural resources, territories and especially religions. In my opinion, laughter is a universal language, which has the ability to humanity without religions. Laughter can build a common connection between various religions and create a new world . The idea may sound over-ambitious, and maybe it is. But maybe it is not. It is our deep that laughter and only the laughter can unite the world, holding up a sense of brotherhood and friendship. Studies also show that laughter helps your body to do the following: lower blood pressure; lighten depression; reduce stress; work out the heart, for those who are unable to perform exercise. So in life, when you can laugh, you should laugh loudly and with your entire body—because it’s good for you.
