The Yellow Emperor asked Zeebe that most people in ancient times could live to be a hundred years old and showed no signs of aging. Now people are just fifty years old, and their movements are weak. Is this because the times are different, or because people have violated the way of keeping in good health? Qi Bo replied: Ancient people generally knew the way of keeping in good health, and they were able to conform to the natural changes of Yin and Yang in heaven and earth and reconcile the methods of keeping in good health in order to reach the correct standard. Eat moderately, work and rest regularly, not hard, and avoid excessive sexual intercourse. So you can coordinate your body and mind, live to the end of your life, and die when you are over 100. Nowadays, people are not like this: they treat wine as water, drink too much, turn abnormal life into habits, get drunk, indulge in sex, and then do their best to dissipate the true qi. I don't know the importance of staying energetic and nourishing the spirit. Only care about temporary happiness, and deviate from the real fun of health care. I don't have a certain routine, so I am old for half a century.
In ancient times, people with high health and self-cultivation often taught people to avoid climate change that might affect people's health all year round; At the same time, keep quiet in thought, have no desire or desire, so that the true qi is hidden inside and the spirit is hidden inside. In this way, the disease will not happen, so their spirit is at ease and they don't have much desire; Peace of mind, fearless; Physical labor is not too tired; The true qi is peaceful and smooth; Everyone can be satisfied and satisfied; Everything tastes good and is comfortable to wear. Everyone loves their own customs and habits, lives happily, and never envies each other's status. Everyone is natural and simple. So any improper hobbies will not attract their attention; Fornication and heresy cannot shake their will; No matter you are stupid, clever, capable or weak, you will not be tempted and anxious about things like wine and color because of changes in external things, which is in line with the way of health preservation. In a word, the reason why they are all over 100 years old and their movements have not obviously declined is because they understand and master the methods of self-cultivation and are not disturbed and hurt by internal and external evils.
The Yellow Emperor asked: When people get old, they lose their fertility. Is it because they lack energy or because they are limited by the laws of nature? Qi Bo replied: As far as the general physiological process is concerned, when a woman reaches the age of seven, her kidneys are full, her teeth have changed and her hair has grown. By the age of fourteen, Tiangui, a substance that can promote reproductive function, has been produced, matured and played a role, making the pulse smooth and vigorous, menstruating on time and having the ability to bear children. By the age of twenty-one, the kidneys were at peace, wisdom teeth came out and the height reached its limit. By the age of twenty-eight, I have strong bones and muscles, the longest hair and the strongest body. By the age of thirty-five, due to the decline of Yangming meridians on the face, the face began to brown and the hair began to fall off. At the age of forty-two, all the meridians of Sanyang declined, with a haggard face and white hair. Forty-nine-year-old, pulse deficiency, weak pulse, lack of day, menstruation cut off, physical aging, unable to give birth.
When a man is eight years old, his kidney is full, which shows that his hair is growing and his teeth are changing. By the age of sixteen, Tiangui is mature, showing the enrichment of essence and the harmony of yin and yang in the body, thus having fertility. By the age of twenty-four, the kidney is peaceful, showing strong bones and muscles, growing wisdom teeth and growing tall enough. By the age of 32, my bones and muscles are stronger and my muscles are more substantial. At the age of forty, kidney qi declined, hair began to fall off and become sparse, and teeth began to loosen. At the age of 48, Yangming's upper meridian failed, his face was gaunt and his hair was half white. At the age of 56, his liver qi declined, he couldn't nourish muscles, his muscles were inconvenient, his movements were slow, his body was exhausted, his essence was insufficient, his kidneys failed, and he suffered from physical and mental pain. At the age of sixty-four, his kidney failed and his teeth fell off. As far as the human body is concerned, the kidney in the five zang-organs controls water, and it accepts the essence of the five zang-organs for storage. Only when the zang-fu organs are full of essence can the kidneys excrete essence. Now I am old, my five internal organs are failing, my bones and muscles are flabby and my body is tired. Therefore, the hair turns white, the body is heavy, the footsteps are not straight, and children cannot be regenerated.
The Yellow Emperor asked: Some people are old and still have fertility. What is the reason? Qi Bo said: This is because his innate energy exceeds ordinary people, his qi and blood meridians are unobstructed, and his kidney qi is abundant. Although there are such people, the general situation is that men are not over 64 years old and women are not over 49 years old. If they use up their essence, they will not be able to have children.
Huangdi asked: Can people who master the way of keeping in good health still have children when they live to 100? Qi Bo A: People who master the way of keeping in good health will age later. Although she is old, there are no signs of decline such as tooth loss, burning face, white hair, heavy body and irregular walking, so she can still give birth despite her age.
The Yellow Emperor said: I heard that there were "real people" in ancient times, who could understand the laws of nature, master the mechanism of transforming everything from yin and yang, spit out the old and absorb the new, nourish the essence, and make the body seem to be integrated with the spirit, and the life span is equivalent to the life of heaven and earth, which is endless. This is because they have mastered the way of keeping in good health.
In the middle ages, there was a kind of person who was slightly inferior to "real people" in terms of health preservation and was called "knowing people". His moral simplicity and comprehensive mastery of the way of keeping in good health enable him to coordinate the changes of Yin and Yang in the body and the universe, adapt to the changes of the four seasons' climate, avoid worldly distractions, and concentrate on wandering alone between heaven and earth, where his vision and hearing can reach far away, which is exactly what makes him prolong his life and make his body healthy. This kind of person also belongs to the category of real people. Secondly, there is a kind of "sage" slightly inferior to "Zhiren". They live in harmony with heaven and earth, obey the changing law of the Eight Winds, and their desires and hobbies adapt to secular habits. Living in secular dust, there is no secular anger and resentment, and the behavior is not divorced from society, but all behaviors do not follow the customs. Outside, don't be exhausted by the office; Don't overload your mind. For the purpose of peace and happiness, to be carefree, the body is not easy to decline, the spirit is not distracted, and the life span can reach about 100 years old.
There is also a person who is good at keeping in good health and has both ability and political integrity, called a "saint". According to the changes of heaven and earth, we can photograph the rising and setting of the sun and the moon, and determine the positions of the stars. Obey the ebb and flow of yin and yang, adjust your body according to the different climates of the four seasons, and follow the example of the ancients in order to conform to the way of health preservation. Such people can live longer, but there is an end.
