　　The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers．However, there is another difference between humans and computers．Computers don't forget information they are given, but humans often do．No one remembers everything, and luckily we don't usually have to．But everyone can improve their memory if they want to．Here are some suggestions．

　　◆Try to use new informati6n immediately．For example, if you meet someone who says "Hi! I'm Carlos, " don't just say "Hello．" Repeat the person's name．Say" ________ "

　　◆Break a big number into smaller parts．For example, it's hard to memorize(记忆)109244153．But if you break it into three parts-109/244/153-it becomes easier．

　　◆Write out what you need to remember ever and over again．This will help you keep it in mind longer, especially for memorizing formulas(公式)or facts．

　　◆Always review information．If you bring what you've learned back to your mind, they become easier to remember．For example, before you go to sleep, it's a good idea to review the new things you learned that clay．

　　◆Discuss with a friend．It is always easier to remember things through discussions．You can have a discussion about what's right and what's wrong, and it will lead to the right answer．

　　◆Never tell yourself that you have a bad memory．You can always do something to help improve your memory．And everyone's memory gets better if they use it often enough．

　　All of the suggestions are helpful．If you follow them, you are certain to improve your memory．

　　Do you want to live a happier, less stressful(有压力的) life? Try laughing for no reason at all．That's how millions of people start their day at Laughter(笑声) 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 7 and 15 times a day,” says Dr．Kataria．“Everyone is naturally good at laughing － it's the common language．We want people to feel happy with their lives．” There are now more than 500 Laughter Clubs in India and over 1,300 in the world．

　　Many doctors are also interested in the effects(效果) 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 silly．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 real laughter and unreal 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．
