In our age of highly developed information, people have more and more knowledge. What they should know, and what they shouldn’t know. What they want to know and what they don’t want to know. Whether we need it or not. All together into our brain. The author believes. Not the more you know, the better. From a longitudinal point of view. The more knowledge people learn. The richer. The more you know. Then our era will be more developed. People’s standard of living will be further improved people’s material life and spiritual and cultural life will be better This is widely recognized. But things are always divided into two. On the one hand, the development of science and technology has greatly improved people’s living standards and spiritual living standards. On the other hand, it also brings great suffering. Then know more and at the same time know more about yourself. In the author’s opinion, either you basically don’t know, or you basically know thoroughly. There is a flurry of information. Most of it is positive, some of it is negative. From the information that we know inside, the information that hurts our food, clothing and shelter makes us feel that the grass is always greener and the cup is always the same reflecting on us as individuals. It is thinking too much. These seriously hurt us. So, excessive medical checkups. Excessive treatment comes into play. But medicine is three parts poison. In fact, many times doctors are helpless, too. But science, it’s not perfect. Science has not yet developed to the point where a doctor can say that someone is 100% fine and it is not in line with dialectics. So it’s up to us to control ourselves. In fact, doctors prefer patients who know less. Such patients are better treated. Sometimes the patient knows more than the doctor. Of course, this more is in quotation marks. Doctors, there is no way out, give patients excessive examination excessive treatment, excessive mental pressure. This may not be good for the patient. You do not see. But all the longevity. All know less. Rely on health and exercise, to maintain good health. Instead of relying on drugs, to live a long life. After all, life is only once people know more will think more so from the root of know, less beautiful Many times, we lack not food and clothing but a pleasant spiritual life.
