Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at laughter Clubs around the world—and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. “ Young children laugh about 300 times a day. Adults laugh between 7and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing—it’s universal（通用的） language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 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 happens at a Laughter Club？ I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest--I wasn’t interested in laughing with a group of strangers, and I 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（假的） laughter and real laughter, so they still produce the same healthy effects.
Surprisingly, it works! After ten minutes everybody 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!

What was discovered by accident？ The answer is penicillin（青霉素）． It kills germs． By killing germs， it saves lives． Suppose you are sick． You go to a doctor． She examines you． She says you have a" staph'" infection（葡萄球菌感染）． She gives you some medicine． You take it． The medicine knocks out the staph． Soon you are well． Before penicillin， this would not happen． Staph was almost sure death．
Everyone wanted a medicine． Laboratories worked day and night． They grew the staph in small dishes． Then they tried to kill it． Nothing worked．

d． Then he saw something strange． Where the mold was， there was no growth of staph． This is what Fleming probably thought． "By accident， I found a mold to kill the dreaded staph．"
This is how penicillin was found． But here's the real miracle（奇迹）． There are thousands of kinds of molds． But only one kind can kill staph． The mold must have fallen into the dish a few days before． The cover was probably off only a few seconds（秒）． In those few seconds the right mold fell into the right dish． Another man might have thrown the dish away． But Fleming was very careful and smart． He understood what the mold did． How lucky the humans were !
