Everybody likes to have a good time, but do you know that laughing is very good for your health? Scientists believe that laughing can help your body fight illness. Because of this, an Indian doctor opened the first laughter club in 1995.

Now there are more than 1,000 laughter clubs around the world. A laughter club is a place where you can go to laugh in your way for happiness and good health. Steve Wilson, the man who took laughter clubs to America, said, “We laugh with each other, but never at each other. At first, the laughter exercise feels a bit false. But soon the laughter becomes real.”

Laughter is very important when we communicate with other people. It helps us make friends and understand each other better. We can laugh with people all over the world. It is the same in any language. So never be afraid to laugh. It’s good for your health.
