PROBLEM: Article: The Dangers of Dieting Thanks to our modern lifestyle, with more and more time spent sitting down in front of computers than ever before, the number of overweight people is at a new high. As people crazily search for a solution to this problem, they often try some of the popular fad diets being offered. Many people see fad diets as harmless ways of losing weight, and they are grateful to have them. Unfortunately, not only don't fad diets usually do the trick, but they can actually be dangerous for your health. Although permanent weight loss is the goal, few are able to achieve it. Experts estimate that 95 percent of dieters return to their starting weight, or even add weight. While the irresponsible or unwise use of fad diets can bring some initial results, long-term results are very rare.[:**] Nonetheless, people who are bored with the difficulties of changing their eating habits often turn to fad diets. Rather than being moderate, fad diets involve extreme dietary changes. They advise eating only one type of food, or they prohibit other types of foods entirely. This results in a situation where a person's body doesn't get all the vitamins and other things that it needs to stay healthy. One popular fad diet recommends eating lots of meat and animal products, while nearly eliminating carbohydrates . A scientific study from Britain found that this diet is very high in fat. According to the study, the increase of damaging fats in the blood can lead to heart disease and, in extreme cases, kidney failure. Furthermore, diets that are too low in carbohydrates can cause the body to use its own muscle for energy. The less muscle you have, the less food you use up, and the result is slower weight loss. Veteran dieters may well ask at this point, "What is the ideal diet?" Well, to some extent, it depends on the individual. A United States government agency has determined that to change your eating habits requires changing your psychology of eating, and everyone has a different psychology. That being said, the British study quoted above recommends a diet that is high in carbohydrates and high in fiber, with portions of fatty foods kept low. According to the study, such a diet is the best for people who want to stay healthy, lose weight, and keep that weight off. And, any dieting program is best undertaken with a doctor's supervision.
Answer: They gain the weight back again.

SOLUTION: After losing weight by dieting, what usually happens to people?

PROBLEM: Article: I was walking along prefix = st1 /Orchard Roadwhen I realized a tall young man wearing a jacket and tie was following me. I noticed him because not many people wear a jacket and tie in the middle of a hot summer day, and I had already seen this man four times that afternoon. To make sure he was following me, I walked on quickly, turned right into a shopping center and then stopped to look in a shop window. Soon the man appeared and stopped at another shop window. I walked on and stopped several times. When I stopped , he stopped too. I began to be rather worried and decided to try to lose this strange man. When I saw a taxi coming, I jumped into it. As I was telling the taxi driver where to go, I found the man get into another taxi, which then followed mine. As the two taxies slowly made their way alongOrchard Road, I looked back at the taxi behind, and saw that the stranger was looking out at me. At MRT station, I told the taxi driver to stop and I got out. As I was paying my fare, I saw the man was getting out of his taxi. By now I got angry, so I turned and walked straight to him. I asked him why he was following me. At first he said he was not following me at all, but when I threatened to call the police, he admitted he was.

PROBLEM: Article: If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise--and as a result, we are aging unnecessarily soon. Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.) Contraction of front and side parts--as cells die off--was observed in some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds. Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age--using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to maintain good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."
Answer: Lawyers.

SOLUTION:
According to the passage, which people seem to age slower than the others?
