As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious (有营养的) foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.

The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.

In today's Internet age, online games can be a change from the pressure of school and work. However, they can also cause problems and unhealthy addictions. This is most clearly seen in the example of South Korea. This country has the world's highest percentage of high-speed Internet services. It has also a high number of game players who are addicted to online games.

In 2004, a young man died after playing online games almost nonstop for 86 hours. A 12-year-old boy stole $16,000 from his father to continue online games which he could not get away from. Such problems are spreading to other parts of Asia as well. In 2005, it was reported that about 80 percent of China's 13.8 million online game players were under 25.

And many of these were said to be addicted. Such numbers point toward a growing problem among Chinese youth.

Dr. Sue-Huei Chen, a psychologist (心理学家), discovered some signs of at-risk people. Such people often go online to escape from their problems. And they usually have no friendship or good social skills. They feel the need to spend more and more time online, so they may be absent from school or family. And they become upset if anyone tries to limit their online game playing.
