Do you want to five a happier less stressful（压力的）life? Try laughing for no reason at all．That's how thousands of people spend their day at Laughter Clubs（A）throughout the world．（B）Dr. Madan Kataria started the first Laughter Club in Mumbai, India．in 1995．There are now（C）more than 500 Laughter Clubs in India and more than 1,300 worldwide．

Many doctors are also interested in the effects of laughter on our health．According to a 5-year study at the UCLA School of Medicine in California，with laughing there is less stress in the body．Laughter improves our health against illness by about 40％．

So，what（D）__________at a Laughter Club? I went along to my nearest dub in South London to find out．I was quite nervous at the（E）________of the class，to be honest-（F）我对和陌生人一起笑不感兴趣，and l was worried about looking stupid．Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha．”while looking at each other．However our bodies can't tell the difference between fake laughter and real laughter, so they still produce the same healthy effects．

Surprisingly, it works! After ten minutes everyone in the room was laughing for real-and some people just couldn't stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you're under stress．then start laughing．You might be very pleased with the results!
