Laughter Clubs in the National Geographic

“No joke is needed to get members of one of Mumbai’s 37 laughing clubs to erupt with glee. Instead, they breathe deeply, yoga-like, reach for the sky to reduce inhibitions, then force a ‘ho, ho, ha, ha’ until the laughter becomes contagious. It reduces stress, claims Dr. Madan Kataria, the clubs’ founder. ‘Laughing is my mission,’ he says, ‘I want to spread it all over the world.’”
