There are many factors which may have an influence on adults and children being able to lead a healthy life.
Nowadays, people are very busy. Often, both parents work outside the home. Children are expected to take on more responsibility at home to help their parents. They also have sporting and leisure activities as well as school expectations.
The busyness also adds another factor: the need to use cars to get from one place to another quickly.
Today, society places a lot of emphasis on technology. Computers, DVDs, CDs, television, Playstations and Xboxes have become major leisure activities, rather than traditional more active pursuits. This has led to a more sedentary lifestyle.
The media provide entertainment and information. Unfortunately, they also promote fast food which fits easily into busy lifestyles. It is much more convenient at times to buy a quick takeaway rather than prepare a meal. The media constantly bombard (轰炸) their audience with "perfect" body images, the need to buy the most fashionable clothes, the most up-to-date computer games, the best places to visit and the best things to do.
Environments vary. We may be exposed to pollution, such as cigarette smoke. This can be harmful to people who suffer from breathing difficulties. Environments where passive smoking is unavoidable make it difficult to lead a healthy life.
Perhaps the important factor influencing healthy lifestyles is motivation, or the desire to be healthy. Any person who wants to be healthy will find a way to be healthy—if he/she is motivated enough!

Passage Four
Increasingly, over the past ten years, people -- especially young people have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount-- but not the quality -- of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. It is significant that nowadays fiber is considered to be an important part of a healthy diet. In white bread, for example, the fiber has been removed. But it is presented in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence emphasis placed on the eating of whole meal bread and more vegetables by modem experts on "healthy eating."

In the aspect of health behavior, the concept of personal choice is very important. According to estimation, around 90 percent of all illnesses may be preventable if individuals would make sound personal health choices on a basis of current medical knowledge. We all enjoy our freedom of choice and do like restrictions when it is in the scope of legal and moral boundaries. The structure of American society allows us to make almost all our own personal decisions that may relate to our health. If we are very eager, we can smoke, drink excessively, refuse to wear seat belts, eat as we like, and live a completely sedentary life--style without any exercise. The freedom of making such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices related to health often results in a difficulty. For example, a teenager may know the facts concerned smoking cigarettes and health but may be pressured by friends into being believing to do it is socially accepted.
A great many factors, both inherited and environmental, have influence on the development of health--related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. The decision to adopt a particular health, related behavior is, however, usually one of personal choices. There are healthy choices and there are unhealthy choices. When Fries and Crapo were discussing the morals of personal choice, they made a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Therefore, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors connecting with a statistical probability of increased vitality and longevity.
