Self-confidence is a positive spiritual factor, which can be transformed into material strength to achieve health and longevity. Confidence is a reflection of tenacious will and cheerful spirit, full of confidence in health and longevity, which can prevent people from "accumulating essence into illness". Self-confidence can make people feel happy, which is conducive to the normal secretion of various hormones in the human body and to regulating the excitement of brain cells and blood circulation. Confidence helps to inspire people's courage to fight against diseases, and stubbornly try to keep fit and get rid of diseases, so as to achieve the goal of health and longevity. Many cases in medical literature have proved that "soothing drugs" have effectively eliminated patients' diseases and even cured diseases that are considered incurable. The "medicine" used in this therapy, the only ingredient that can cause effect, is obviously the strength generated by the patient's own self-confidence.
Modern scientific research shows that people with good ideas to save the world and benefit the people can secrete healthy substances, thus promoting health and longevity.
One of the reasons why people are aging is the decline of the body's adaptability. A large number of investigations and studies have confirmed that most people engaged in creative labor belong to people with strong nervous activity, and their nervous system is more developed than ordinary people. It can be seen that the happiness of career success and the good psychological state of focusing on career are important factors for human health and longevity.
