Good health is the most valuable thing a person can have but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape, eat right food, get enough sleep, and exercise regularly.

    Proper nutrition is important for good health. Your body cannot work well unless it receives the proper kind "fuel". Don't eat too much food with lots of sugar and fat, eat plenty of foods high in protein, like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat It is not helpful to be overweight

    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality(人的个性).Be sure to allow yourself from seven to nine hours of sleep each. If you do, your body will feel strong and refreshed, and your mind will be sharp.

    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span(寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on. Sports are not only good for your body, but they are enjoyable and interesting, too.

    If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

    Eating chips, chocolates and cakes may damage a child's intelligence, according to researchers at Bristol University. Their study suggests a link between diet high in processed(加工的) food and a slightly lower IQ. Writing in the journal of Epidemiology and Community health, they suggest poor nutrition may affect brain development.

    The eating habits of 3,966 children taking part in the Avon Longitudinal Study of Parents and Children were recorded at the ages of three, four, seven and eight and a half. The researchers said three types of diet appeared: processed diet which was high in fat, sugar and fast food, traditional diet of meat, potatoes and vegetables, and healthy diet of salads, fruit and fish. The children all took IQ tests when they were eight and a half.

    The researchers found a link between IQ and diet, even after taking into consideration other factors such as the mother's level of education and social class. Diet high in processed food at the age of three was linked to a slightly lower IQ at the age of eight and a half, suggesting early eating habits have a long-term influence. Dr Pauline Emmett, who carried out the study at Bristol University, said, “Brain development is much faster in early life, and it's when it does most of its growing.”

    Although the relationship between diet and IQ was very strong, the influence was quite small. Processed food was linked with IQs only a few points lower. Experts in the field said the results had shown common sense was right. Fiona Ford, spokesperson for the British Dietetic Association, said, “It's well worth looking at the long-term influence of diet, for everyone's familiar with the short term. The research agrees with the type of advice we already know, but that's not always enough. Sometimes a society has to help a person change; we need to educate more young parents about healthy eating.”

Internet time tied to teen depression(抑郁) symptoms

    Spending time online is normal behaviour for teenagers. But too much Internet use by teens —or too little, for that matter —might be related to depression, a new study finds.

    The findings, reported in the journal of Pediatrics, do not mean that the Internet is to blame. For one, teens in the study who spent no time online were also at increased risk of depression symptoms. Instead, the researchers say that both heavy Internet use, and non-use, could serve as signals that a teenager is having a hard time.

    For the study, Dr. Pierre-Andre Michaud and his colleagues at the University of Lausanne, Switzerland, surveyed 7,200 individuals aged 16 to 20 about their Internet use.

    Those who were online more than two hours per day were considered "heavy" Internet users, while those online anywhere from several times per week to two hours per day were considered "regular" users.

    The teenagers also answered a number of health-related questions, including some standard questions about "depressive tendencies" that gauge(判定) how often a person feels sad or hopeless. Compared with regular Internet users, the study found, kids who were heavy users or non-users were more likely to be depressed or very depressed.

    Among male teens, heavy users and non-users were both around one-third more likely to have a high depression score, compared to "regular" users. Among girls, heavy Internet users had an 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.

    That was with factors like family income and any chronic health problems taken into account.

    Since teenagers typically go online to contact with friends, the researchers speculate(推测) that those who are never online may be more socially isolated.

A good story. That's what influences our choice to buy a book the most. Right? Some of the biggest-selling novels of all time just so happened to be attached to major publishers. Indeed, any reading lover will be familiar with the countless publishing houses that have brought brilliant works to the market. So in theory, perhaps a publisher does matter. 

Every time you read a book that you enjoy, you likely look at the publisher attached to it. That name is a signal that they will produce other content that fits with that same style. It makes a lot of sense to continue to purchase texts from a company that is telling the kinds of stories that you enjoy the most. Consumer habits are thus based on trust that a publisher will be consistent in the books they deliver and that investing time in them is more reliable than an untested source.

The strength of the author themselves can also play into that. After all, well-liked authors are often signed to a book deal with a select few publishers, strengthening the brand further. 

Of course, a publisher would be nothing without its logo, which is a major call-to-arms for all fans of the brand. The top publishers in the world instantly recognizable imagery, which catch the attention while summing up the name of a brand in an instant. That thus builds our association with a given name. The fun penguin shape of Penguin Random House is so iconic, for example, that it could not be confused with any other publishing business.

There might be a place for those indie (独立经营的) book companies, with occasional stories breaking through and forcing people to take notice. In truth that's far less common than you expect. Expert Cassandra Davis, however, provides a hopeful insight. "Indie bookshops are more likely to stock an indie publisher's books, especially if the author is local to the bookshop." She says. Therefore, supporting local bookshops is a vital way to keep the indie industry alive and change these trends.
