the doctor, madan kataria, gathered a group of people together in a local park to practice laughing as part of a "laughter club". During the club meetings, Kataria would prompt members to laugh in a variety of ways. For example,he would tell them to greet one another with a laugh, or to laugh like a lion. Although Kataria discovered that fake laughter produces the same health benefits as genuine laughter, he was gratifird to find that it usually didn't take long for fake laughter to turn into real laughter.
