Per capita quality and quality of life determine livability and life expectancy, and the improvement of per capita quality and quality of life is usually due to the development of science and technology. Generally speaking, the more advanced the science and technology, the more livable the area is, and the longer the natural life span is, and vice versa.
If a region is developed in science and technology, its corresponding food, medicine, daily necessities, medical care, housing, social security, education and per capita quality will be improved. The reverse is also true.
Take Shanghai and Xizang Autonomous Region as examples:
Shanghai is a national central city, a megacity, an international financial center and a world-famous port city. Shanghai has almost concentrated the best talents and resources in the country. Fudan University, Tongji University, Shanghai Jiaotong University, East China Normal University and other well-known universities in China are all concentrated in Shanghai. It also has the best medical conditions in China: Huashan Hospital of Fudan University, tongji hospital of Tongji University, Affiliated Hospital of Shanghai Jiaotong University, etc. Science and technology are developed, and naturally the living standards of residents in this area are extremely high. In Shanghai, natural life expectancy will also increase.
Located on the Qinghai-Tibet Plateau, the highest altitude in the world, Xizang Autonomous Region is isolated from the rest of the world and has extremely inconvenient transportation. It is also one of the last liberated cities in China. Due to natural conditions and backward transportation, Tibetan residents have little contact with the outside world and their economy is very backward. Due to isolation from the outside world, the local residents have primitive lives, low living standards, backward medical conditions and reduced natural life expectancy.
