When a person is healthy, he doesn't feel how happy he is. He just feels that this is his normal life. For example, he doesn't have any disease, not to mention how strong he is, but he is still at the level of a healthy person. He works normally every day, studies normally, falls in love normally and then has his own family life. This is the life track of a normal person, because he starts as a student, then enters the society, then falls in love, then gets married, and grows old slowly, without feeling how happy he is. He just thinks this is his normal life.
When a person has physical problems, he will know the value of health. For example, when he was in his 40 s, he had stomach trouble or high blood pressure, and he controlled his diet, or he had diabetes, and he took injections every day. At this time, he suddenly recalled how happy he was to be so healthy when he was young, but it was too late. People don't cherish what they once had, and feel extremely precious about what is about to be lost and irreparable, just as people suddenly feel that they can play freely outside now.
We should cherish our healthy body, which is reflected in the attention to the spirit and the maintenance of the body. Spiritual concern is to know that health brings us a happy life, and we are satisfied every day. After all, contentment means being healthy now. We should cherish this health, rest regularly every day, eat regularly and exercise regularly to ensure our health.
