Scientific qigong is the most effective way to delay aging and prolong life. People's brain cells are at their peak at the age of 2 0, and begin to decline after the age of 2 0, and other organs begin to transform into aging after the age of 3 0. With the increase of age, the activity of brain cells, organism and intelligence level will gradually decrease, which is a progressive physiological aging process. To prolong life healthily, we must first strengthen the brain, improve the level of intelligence and delay the aging of intelligence. Insisting on practicing Qigong can activate brain cells, delay the aging of brain cells and body, improve the quality of life, prolong life, and even prevent Alzheimer's disease, which has been confirmed by many practitioners. The scientific experimental research on delaying the intelligent aging of middle-aged and elderly people shows that after short-term (6 months) practice of "Fitness Qigong Yijinjing", the intelligent physiological age and aging degree are obviously reduced; Qigong exercise can obviously improve the mental agility, movement flexibility, short-term memory and attention quality of the elderly, and can delay the mental decline of the middle-aged and elderly people.

A large number of qigong experimental studies have proved that practicing qigong can significantly improve people's cardiovascular and cerebrovascular functions and lung functions, and middle-aged and elderly people can achieve practical results after practicing for half a year. For example, Zhang Yinggen's experimental research on fitness qigong shows that it can improve people's bad psychological state psychologically; It can dredge human meridians, ensure the smooth operation of qi and blood, and improve the blood supply function of cardiovascular and cerebrovascular diseases; It can increase cardiac output, reduce peripheral resistance, improve vascular compliance and reduce blood pressure in patients with hypertension; It can improve the elasticity of cerebrovascular wall, reduce cerebral blood flow resistance and cerebrovascular tension, increase blood supply to the brain, and make the blood supply to both sides of the brain more consistent.
