"An apple a day keeps the doctor away." Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important? The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive. Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration--a lack  of water in the body. Most people are dehydrated at least some of time, although they probably don't know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty. These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water. There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often. We need   _  for a healthy diet.

New research has shown that loneliness may affect ants to a greater extent than many other living creatures. It has long been known that loneliness can lead to a shorter life. In humans, it has even been found to be a driver of high blood pressure, sleep disorder, and depression that's independent of factors like age, race, gender, weight and economic status. However, loneliness has never been identified as a factor that can cut human lifespan by more than a small part of the average. Ants, on the other hand, appear to be far more sensitive to this stress, with loneliness leading to a surprising 91 percent reduction in lifespan. That's at least according to a study that details how "lonely" ants only live up to six days on average. Ants living in a community, on the other hand, were found to live up to about 66 days. In a series of experiments where ants were picked from their colonies   and separated, they were found to continuously walk without rest,consuming far more energy than they could ever. The reason for the behavior is that an isolated ant is simple trying to get back to its colony at all costs, and doesn't know what to do without its nest mates. After all, many entomologists   would argue that an ant colony is far more a single living entity   than its members. If you were to take a single part from a clock, it would simply move aimlessly as well, running without a purpose. However, while there is a difference between aimlessness and loneliness, the researchers found that the latter affects lonely ants more directly. The study indicated that ants can't even eat alone, as they normally collect some of the food they gather in the field in a specialized organ called a crop.This crop is normally shared with other ants back at a nest,but as for a single ant, it simply just sits there, undigested and useless. How does loneliness influence a person? A) It can make him very tired of himself. B) It can leave him in conflict with others. C) It can lead to him being very independent. D) It can cause him to suffer from poor health
