There are many similar jokes on the Internet. For example, so-and-so did not smoke or drink, and only lived to be 60 years old, while Zhang Xueliang lived to be 100 years old.
In fact, in the eyes of doctors, these jokes are just entertaining and have no scientific reason.
If there is any scientific truth in this. It can only be said that it is helpful for health and longevity if people let go of themselves, keep a happy mood for a long time and do not suppress their nature. But it can't be said that bad living habits contribute to health.
Disease is a very complicated result of many factors. At present, the pathogenesis of many diseases is unknown and very complicated. And the human body is also a very complex collection.
Therefore, in medicine, a single case cannot represent everything, nor can it explain any problems.
In order to avoid the errors caused by individual cases, we must go through a lot of research, include many observation people and eliminate all kinds of interference factors before reaching medical conclusions. Finally, a relatively accurate conclusion can be drawn through very complicated statistical methods.
Therefore, the correct scientific research method should be to clone thousands of Show Lo, randomly divide them into a good habit group and a bad habit group, and then live according to different living habits, and observe 10 years or even longer before reaching scientific conclusions.
You only see Show Lo drinking and staying up late to indulge, but you don't see that he may be diligent in fitness, cheerful, without financial pressure, reasonable diet structure, living environment, air quality, high medical level and other factors, or Show Lo himself has longevity genes.
In many medical experiments, in order to avoid the different effects of different genes on the body, inbred mice, that is, mice with close relatives, are used, and their genes are similar. The drug experiment and other experiments done in this way are convincing.
Smoking, drinking, bad eating habits, and staying up late are harmful to your health. They are also the conclusions of many long-term large-scale clinical observation experiments, which can be said to be very scientific. The development of the disease is also a very long process, and some consequences were not visible at that time.
Many people think that the theory of traditional Chinese medicine is too mysterious and ancient, so it is unscientific. In fact, the theory of traditional Chinese medicine is also a large-scale clinical trial that has lasted for thousands of years. Numerous sages have discovered a series of laws about health and human body after years of observation and summary, and summarized them into words. Its scientific nature is beyond doubt.
Therefore, we can't deny the uselessness of health preservation just by one example. Still have to develop good living habits.
