ocr: Noj joke is needed to get members of one of Mumbai's 37 laughing clubs to erupt with glee. In- stead, 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 re- duces: stress, claims Dr. Madan Kataria, the clubs' founder. "Laughing is my mission," he says. "Iwant to: spread it all over the world."
