Generally speaking, people who think they are healthy will not pay attention to health preservation, because they will think it is redundant and even trample on their bodies, and there are a lot of junk food, staying up late and so on. It is not until one day that their health goes wrong that they will think of keeping healthy. If you don't keep healthy, you may be fine all your life, but you may also get chronic diseases (such as three highs) and even cancer. Symptoms are often related to patients' eating habits, living habits and environment.
