Why laughter matters
Although most people believe that laughter is one of the nature's great treatments for a whole range of mental and physical diseases, it is still a serious scientific subject that researchers are trying to figure out.
“Laughter above all else is a social thing，” says Baltimore neuroscientist, Robert Provine, who has studied laughter for decades. “All laughter groups laugh ‘hahaha’ basically the same way. Whether you speak Mandarin, French or English, everyone will understand laughter. There is a pattern generator(发生器) in our brain that produces this sound.”
