These people began to pay attention to health preservation because they realized that good health is the most important thing in life. Many of my friends and relatives are in this situation. One of them is his next of kin.
This close relative has always been in excellent health when he was young, and even colds are rare, so he doesn't pay attention to health at all. He smokes two or three packs of cigarettes a day and especially likes spicy food. One day, he suddenly found a hard pimple on the back of his ear, which didn't go away after a long time, so he went to the hospital for examination. According to his description, the doctor began to suspect that he had nasopharyngeal carcinoma. Fortunately, after biopsy, it was found that it was only lymph node inflammation.
But the doctor also told him that he must develop good living habits, quit smoking and pay attention to health, otherwise he is likely to suffer from other diseases. At this point, this close relative began to pay great attention to health. After smoking for decades, I really quit. I also know that I should drink more water and eat less spicy food every day, and I often ask some health care methods.
In short, what is lost is precious. When a person loses money, he will feel that money is the most important thing, and when he gets money but loses health, he will realize that health is more important. In this way, it is normal that people who pay attention to health are generally in poor health.
