People know Ma Yinchu mostly from his time as a demographer, because he dared to oppose Chairman Mao's decision that "many hands make light work". It was not until the reform and opening up period that he was recognized by the party and the government as correct. However, people don't know whether he has lived 10 1 year. Even when he was 90 years old, he got cancer. Ten years later, the cancer cells did not metastasize and spread, and the cancer never recurred. According to the present situation, he will be an "anti-cancer star".

When talking about his long life experience, Ma Yinchu said: "The two things that are most beneficial to my health are hot and cold baths and mountain climbing." So, how did he do it?

Young people in Ma Yinchu have been in poor health due to poor economic conditions and malnutrition. After he was recommended by Beiyang University to study at Yale University in the United States, he made up his mind to step up physical exercise after studying to adapt to the heavy study work in the future. At that time, everyone in Yale stipulated that swimming was a compulsory course, and those who could not swim were not allowed to graduate. In order to keep the water clean, the school requires everyone to take a cold shower before swimming. Ma Yinchu exercised in this way, and finally greatly enhanced his physique.

In the cold water bath, he met a 93-year-old doctor with golden hair and childish face, and got the fitness method he insisted on all his life-hot and cold water bath method. The old doctor told him that the specific method is to wash it with hot water first, and the water temperature is limited to the physiological endurance of the body. After washing, soak in hot water 15 minutes. Dry yourself with a towel after taking a bath. After three or four minutes, soak in cold water or shower with cold water to make the body temperature equal to that of cold water. Its principle is: when taking a hot bath, the pores are enlarged, and the dirty things in the body are discharged through sweating, which promotes metabolism and makes people feel comfortable; One cold and one heat make the blood vessels of the whole body expand and contract, exercise the elasticity of blood vessels, delay the aging of people and achieve the purpose of prolonging life.

Ma Yinchu's practice. As a result, his physical fitness gradually changed from weak to strong, and his physical resistance was greatly improved. During his three years at Yale University, he almost never got sick. Besides taking hot and cold baths, he has to have a massage before going to bed every day, mainly on his chest at night and on his face in the morning.

Of course, he also has an important exercise program-mountaineering. This habit was formed when he was studying at Columbia University in the United States, and he persisted for more than 40 years after returning home. In 1950s, Ma Yinchu held several important positions in the country besides being the president of Peking University. Even so, he insisted on climbing the mountain. Even about mountaineering, some people think of him in the mountain city of Chongqing. Ma Yinchu always walks when he goes out, and never takes a "slide pole". Someone joked with him: "You are a doctor of economics, but you are really' economics'!" Ma Yinchu pays attention to exercise and has perseverance. Even when his legs were paralyzed and he was hospitalized due to illness at the age of 100, he still insisted on exercising as much as possible. Once it was raining in Mao Mao outside, and the nursing staff didn't push him out. He shouted to go out: "it's nothing to rain a little, but you should exercise in heavy rain." He died on1May, 982 10, and wrote a March for people with practical actions.
