After the age of 30, every organ of the body began to degenerate. Although the deterioration of internal structure is irreversible, the body function can be kept in a healthy state through exercise and conditioning. With the change of modern life, more and more people have developed bad habits, such as staying up late, eating irritating food, drinking and smoking, and all kinds of stress, which seriously endanger their health. Being in an irregular environment for a long time is easy to cause palpitations, memory loss, weak resistance and other symptoms, so many people's health will get worse and worse.

Many people think that the air quality in cities is poor and dusty, and they like to close the doors and windows of their rooms. In fact, people constantly exhale carbon dioxide and inhale oxygen indoors, which will make the oxygen content in the air less and less.

Bad lifestyles have led to many chronic diseases. Some experts pointed out that only by attaching great importance to the health of the whole people, popularizing basic medical care, strengthening national fitness, advocating a healthy lifestyle and reducing the incidence of some major diseases can we reduce the premature retirement of the whole people.

And many people are exercising, but their physical condition has not improved. That's because the method of exercise may be wrong. If you exercise blindly, it will only accelerate the aging of the body, but it can't effectively delay aging. The same is true in diet. Careless diet can also harm our health. Maybe many people don't know it, but in fact our bodies are very fragile. So many people are not old now, but their physical age is much older and their physical quality is declining. Therefore, for the sake of our health, we should treat our bodies well.
