After reading this book, I feel that for thousands of years, human beings have tried their best to pursue the art of immortality, but they have always been unable to solve the mystery of life. What are the fundamental factors that govern human growth, development, reproduction, and aging? Why do some people live long lives while others die young due to genetic diseases? Why do the same medicines treat the same disease, but the effects vary from person to person? Why do some people get fat easily while others don't get fat when they eat the same food? They have been described one by one in this book.
