We all know laughter can be contagious. But can it be a good workout?  A form of therapy?  Even a skill?  Many happy devotees think, yes. Inspired in part by the growing popularity of laughter yoga, filmmaker and journalist Albert Nerenberg hosted the first official laughing contest in Montreal back in 2011. He’s also the director of the 2009 documentary, Laughology.
