Laughter I think we have two different kinds of laughing; the good one and the bad one. The bad one comes with stress. I wana talk about the good one. This kind of laughter depends on our culture, age, situation, etc. Maybe what was funny thirty years ago doesn't make you laugh these days! Laughing itself is a very complicated thing but we can use it to develop our relations in the society. It's interesting that we're not the only creatures with the ability of laughing. Scientists say that chimpanzees and rats can laugh! Maybe they do this for connecting each other. Also laughing can be helpful for our health! It can protect our immune system and blood vessels or reduce our pains. So laughing is a good medicine! “Laughology” the science of laughing can help us caring patients!
