With the rapid development of urban life, people's physical and mental pressures are rising and their lives are irregular. After retirement, the body and mind are relaxed and the sense of pressure is gone, so various symptoms appear. Some people have just retired and left, but they will not appear in the countryside. In cities, noise is very harmful to human health. When people want to rest, noise will affect people's sleep, reduce people's immunity and seriously affect people's health.
Air pollution is the most serious problem in cities. Daily traffic causes carbon dioxide and some harmful substances in the air to seriously endanger people's health, and the number of middle-aged and elderly people suffering from cancer is increasing. People in the city eat and drink like that. As the saying goes, illness comes from the mouth. Life lies in exercise. Old people in rural areas are sixty or seventy years old, and they will not lose their jobs as long as their health permits. Except for housework, they work at sunrise and rest at sunset, and the farming method has not completely changed. Sweating in summer and undressing in cold weather are also unintentional physical exercises. City people should do morning exercises and take a walk after meals for health care. The elderly in rural areas have more labor activities, strong body and strong spirit.
