The back part of the brain which controls tasks like eating and breathing, doesn't contract(萎缩)with the age.

　Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for yeas. Now researchers say there are three different types of loneliness.

　　The first kind of loneliness is temporary（暂时的）. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation-for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.

　　The third kind of loneliness is the most severe. Unlike the second type, chronic（长期的）usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.

Psychologists agree that one important factor in loneliness is a person's social contacts, e.g. friends, family members, co-workers, etc. we depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.

　　Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be normal, healthy part of life, chronic loneliness can be a sad, and sometimes dangerous condition.

Most forest fires are caused by human carelessness, negligence, or ignorance. Forest fire prevention, therefore, is mainly a problem of creating a better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger. This is not an easy job. A city dweller, used to paved street, does not easily change his smoking habits when he goes into the woods.

Careless smokers are responsible for thousands of forest fires each year. Many of these are started when cigarette butts and matches are tossed from automobiles. Others are caused by hunters, hikers, fishermen, or woods workers who are careless in disposing of their smoking material. The Forest Service has posted rules in many of the National Forests that prohibit smoking except in certain designated areas. Many of the states have laws against throwing lighted materials from automobiles. The prevention of smoker-caused fires, however, depends upon changing the attitudes and behavior of millions of people who smoke in hazardous area.

The most important natural cause of fire is lightning. This accounts for 11 percent of forest fires on protected land for the entire nation. In the western states, lightning causes a much higher percentage of fire than it does in the east.

Advances in knowledge of fire weather are helping forest protection forces to know when to be alert for lightning-caused fires. Adequate and well-equipped forces can control them quickly and hold the damage to a minimum. Experiments in “seeding” thunder clouds to prevent or control the lightning itself have been in process for many years, but new breakthroughs are needed for any significant reduction in the lightning starts.
