    Kataria is the founder of the worldwide laughter  movement.  The  celebration  of World Laughter

Day is a positive activity for world peace and is intended to build up a global sense of brotherhood

and friendship through laughter. The first "World Laughter Day" gathering took place in Mumbai,

India, on 11th January, 1998. 12,000 members from India and international Laughter Clubs attended

it. Now there are over 5,000 Laughter Clubs worldwide on all 5 continents.

     "HAPPYDEMIC" was the first World Laughter Day gathering outside India. It took place on 9th

January, two years after the Mumbai gathering.  In Copenhagen, Denmark, more than 10,000 people

gathered at Town Hall Square. The event went into Guinness Book of World Records."World Laughter

Day" is now organized on the first Sunday of May every year. Hundreds of people gather worldwide

on that day to laugh together.

     Today, many people fear widespread international terrorism. The world has never faced so much

unrest before. People are at war within themselves. Laughter is a universal language, which has the

ability to unite humanity without religion. Laughter can build a common connection between various

religions and create a new world order. The idea may sound overambitious(野心太大的), and maybe

it is. But maybe it is not. It is our deep belief that laughter and only laughter can unite the world, building

up a global sense of brotherhood and friendship.

     Studies also say that laughter helps your body do the following:  lower blood  pressure;  lighten

depression;  reduce stress; work out the heart, especially for those who are unable to perform physical

exercise. So in life, when you can laugh, you should laugh loudly and with your entire body-because it's

good for you.
