Laughter club

Members of the Laughter Yoga club practise laughing during morning exercise at a public park in Hanoi September 24, 2011. For the past two years, several hundred people have been gathering each morning at a public park in central Hanoi to practise laughing under the instruction of yoga master Le Anh Son in the belief that this will help them to be happier, fight disease and relief the stresses of daily life. Laughter yoga was launched in 1995 by Dr. Madan Kataria, a physician, in India and there are now more than 6,000 clubs in 60 countries, Son said. REUTERS/Kham
