VANCOUVER, British Columbia (AP) — Louise Ayotte is attracted to people who laugh, loud and a lot.
Wanting to be more like them, she signed up for a class on how to unleash more contagious giggles.

What Ayotte got was three hours of heavy breathing, face-making and laughing with Dr. Madan Kataria, a Bombay, India, physician with a global following who's making a rare tour of Canada to train aspiring laughter coaches.

Kataria's teachings have inspired people to form clubs and follow his lead in search of the incredible release of unstoppable laughter.

"I train people to laugh without humor or jokes. Jokes are intellectual. Not everyone gets it. We laugh at nothing as a form of exercise," he said.
