I will never forget that feeling. I got a winter night. After I left, I was exhausted for several hours in the empty street of the hospital. I suddenly realized that I no longer felt nervous and tired. All the patients who are worried about my illness, as well as my personal concern, seem to evaporate quickly like the black smoke vapor in my breath on a cold night. When I walked into my schedule, not only my mood was encouraged, but also my weight and blood pressure gradually decreased. I began to look up medical literature about walking. From this research and my clinical observation as a family doctor, I found that no matter your age, it is possible to follow your healthy path, fine-tune your body and prolong your life. Like swimming, cycling and running, walking is an aerobic exercise, which can increase energy output and physical endurance, increase oxygen supply and increase skin and muscle capacity. This kind of exercise may be the main factor to prevent heart and circulatory diseases.
It is considered that it may be the least laborious and safest aerobic exercise, and walking is the most acceptable exercise for most people. Walking at a comfortable speed can improve the efficiency of the cardiopulmonary system that stimulates the lungs and heart, but it is more gradual than most other forms of exercise. (279 words)
I was speechless for a long time.
