Some people choose 400 celebrities from Europe and America since the 20th century to compare which kind of people have the longest life span. As a result, they found that learners live in the first place. Some people in China have also made a statistical analysis of the life span of famous intellectuals since the Qin and Han Dynasties 13088. The results show that the life expectancy of those scholars far exceeds that of other professionals. A few years ago, the Swiss Reader's Literature Business Daily reported that "many experts engaged in gerontology found that reading and learning are closely related to physical and mental health and longevity." Dr. John Moses, who is engaged in the research of geriatric physiology, said: "Reading and learning is an activity involving the whole body ... It also involves reflection, which is an activity we call intention. In my opinion, no matter young or old, there are usually requirements for reading and studying, which will make people healthy. "
In some developed countries in the world today, "reading therapy" has become a fashion. Many hospitals in Germany, France and Italy also set up libraries specially for patients, and there are specialized doctors to guide patients to cooperate with "reading therapy" to speed up patients' rehabilitation.
