For middle-aged and elderly people, everyone wants to live a long and healthy life, paying special attention to the way of health preservation. Let me give you some examples. 1. My wife's uncle died of lung cancer many years ago. He never smoked before, at the age of 86. My wife's second uncle is 9 1 year old this year. Smoking a pack of Huang Nanjing cigarettes every day, each pack of 20 yuan, is a habit formed for many years and is in good health. He usually doesn't drink 100 wine, sometimes he drinks red wine, but he drinks strong tea with green tea every day. The price of tea doesn't have to be high, but there are many teas for making tea. American biologists do feeding experiments on mice. The normal life span of mice is about three years, and mice will die of hypertension, diabetes, cancer, leukemia and other diseases when they are old. Biologists divided mice into two groups and fed them the same food. The first group, unlimited quantity, will be replenished immediately after eating. The second group, restricted food, made it semi-hungry for a long time. Finally, it is surprising to find that one group of mice died of illness one after another in about three years, while the life span of the second group of mice was as short as four years and as long as more than five years, and the average life span increased by 50%! 3. yes. When the reporter interviewed health of the elderly, who is 102 years old, he discussed the way to live a long life. The old man said I was illiterate and uneducated, but I only knew two things: First, I had to pull weeds and pick vegetables in the fields every day; Second, I haven't had a full meal, and his way to live a long life is as simple as that. Give a few examples to illustrate a core problem. When the metabolic function of human or animal is very strong, the body will be healthy and there will be no diseases. Smoking won't get lung cancer. On the contrary, not smoking can't guarantee that you won't get lung cancer. Maintaining vigorous metabolism is the basic guarantee of health and longevity. It is unprecedented and impossible to live a long and healthy life by eating supplements and nutrients since ancient times. I have also entered old age. I think that as long as people exercise properly and feel hungry, there will be no disease. Take myself as an example. In addition to proper exercise every day, I keep my mouth shut and control my food intake every day. I don't eat much every morning. I was hungry in the morning 10, and didn't eat much at noon. I started to be hungry at 4 pm and didn't eat much. Although I don't smoke much during the day, I have formed the habit of drinking about three or two liquors every night. My unit goes to the provincial hospital of traditional Chinese medicine for physical examination once a year.
