We often put life, old age, illness and death together, but strictly speaking, illness is not the same as life, old age and death. There are many complicated reasons for the occurrence of major diseases, and there is also a relatively long process, which is beyond our intervention and change.
In ancient China, Bian Que once put forward "treating diseases before they occur", which shows that many diseases can be traced before they really occur. In modern society, with the development of medicine, we have learned more about the truth of diseases than in the past, and have more detection means, so that we can know the existence of diseases in time and treat them.
Today and in the future, with the development of life science and the further study of gene and molecular biology, we can diagnose whether a person has congenital diseases before birth, and know a person's risk preference through disease susceptibility gene testing when the child is very young.
In other words, modern science has been able to detect which aspects of your genes are weak and prone to illness, which gives people enough time to take preventive measures in advance. For example, if a person detects that drinking alcohol is harmful to the liver, or the risk of liver disease is high, then don't drink alcohol, strictly stay away from the source of liver disease infection, and do a good job in liver maintenance as soon as possible.
Since entering the modern society, the economy has developed rapidly, and great changes have taken place in our diet structure and lifestyle. We have countless kinds of snacks and entertainment than in the past.
To tell the truth, our bodies were domesticated in the 5,000-year lifestyle of "sunrise and sunset" and "whole grains", and it is normal that we can't adapt to the great changes in life in the past 200 years. "Modern disease" is the "disease-free" that we have faced and can foresee in the future.
However, before the development and popularization of the corresponding science and technology, it is still necessary to maintain a healthy lifestyle, pay attention to diet and work and rest, and reduce the risk of illness.
