2. The causes of the disease are complicated, and none of them are caused by a single factor. For example, the balance of physical mechanism is broken, the immune system is not effective enough, the combat experience is insufficient, the logistics resources are insufficient, and mental or emotional instability can also cause diseases. Generally speaking, when the ability of human body's maintenance mechanism is not enough to resist injury and loss, it will cause diseases.
3. The physiological mechanism of the human body will make the best adjustment to the human body system according to the physiological condition, so that the human body is in a balanced state. As long as this mechanism does not collapse, it is healthy.
4,5. The relationship between physical and mental diseases and the causes of social and psychological diseases are strictly the same, both caused by the environment. The so-called environment refers to the growth factors and conditions that people themselves give to diseases or health, because both health and diseases need a place suitable for their growth. If the human body gives itself a healthy land, the growth of pathogens will be inhibited. If the same human body gives itself a piece of death, the seeds of disease will grow rapidly. Like life and death, health and disease have the same origin, but they are opposite to each other but go hand in hand. Good health, but being sick is not necessarily a bad thing!
