According to the research of scientists, pessimism, depression and unhappiness will change people's physiology. In this way, some human organs will be in an unhealthy state, and even gradually become diseased. On the contrary, optimistic mood or positive attitude can keep people's physiology in a very harmonious state, and the operation of physiological system is always conducive to the health of various functional organs of the body. Therefore, optimistic mood or positive attitude is conducive to physical health and disease recovery.

As the saying goes, smile, ten years old. The road of life is not smooth, there are opportunities and challenges, there are bitter memories and sweet memories, and optimism is a kind of capital, a healthy mentality and a source of happiness. It is like warm sunshine and full of sacred power. Cultivate a healthy attitude with optimistic psychology and establish a correct outlook on life with a healthy attitude! So having an optimistic attitude means having a healthy attitude and a happy and healthy life. (serious nonsense, forgive me! )
