Bei Zhangshi, a scholar of Chinese Academy of Sciences, asked why smoking can live longer than 60 years.

Bei Zhangshi, a scholar of China Academy of Sciences, is a famous biologist in China and the oldest academician of China Academy of Sciences. He died in 2009 at the age of 107. At such an advanced age, many people began to explore the mystery of academician's longevity. As we all know, smoking and drinking are the most influential living habits, and Academician Bei has a history of smoking for more than 60 years. Why did he live so long?

First, he has enough self-discipline. Academician Bei Zhangshi learned to smoke when he was studying in Germany in his early years. Although he has a smoking history of more than 60 years, he really quit when he wanted to quit smoking later. This perseverance is admirable, and what you can do in life never bothers others. When he is old, he will try his best to do the housework within his power and have a good plan for his life.

Second, to ensure a balanced diet, Academician Bei Zhangshi adhered to the principle of eating well in the morning, eating well at noon and eating less at night, seldom eating high-calorie and spicy food, trying to keep the taste light, never picky about food, never eating snacks in normal life, ensuring the regularity of three meals and balanced nutrition, and fundamentally preventing diseases from entering the mouth.

Third, keep a positive and healthy attitude, which can affect a person's health. Academician Bei Zhangshi likes making friends with young people very much. In the process of communicating with young people, he can keep his brain active and feel the vigorous vitality of young people, and those negative emotions in life will disappear invisibly, which can also ensure the health of his brain.

Fourth, insist on physical exercise all the year round. Life lies in exercise. If you want to live a long and healthy life, you should insist on regular exercise. Exercise can promote blood circulation, strengthen metabolism and increase the flexibility of muscles and joints. When Bei Zhangshi was young, he walked to and from work and walked 3,000 steps back and forth for more than 40 years. After retirement, he often walks at home, massages his body and joints, and exercises all the year round to keep him healthy and energetic.
