Just as comparison is relative and conditional, two different statements correspond to different angle rules. The opening of Huangdi Neijing says:? People in ancient times were all 100 years old. ? And Qi Bo replied:? Those who know, the law lies in yin and yang, but in tricks. They eat and drink well, live a regular life and do things without recklessness. Therefore, they can be in harmony with God, and they will come to the end of their lives. ? People who can live to be over 100 here refer to people who know how to keep in good health. Are they all in the eyes of the Yellow Emperor? Living between animals, action is to avoid the cold, and shade is to escape the heat. ? Ancient people.
The first possibility is that the longevity of the ancients is true, because there is a unique way to gather qi to keep fit. According to Biographies of Laozi and Han Fei, Gai Laozi is over 60 years old, or over 200 years old, and lives by practicing Buddhism. ? Gai means speculation, while constant desire is Lao Tzu's method of health preservation and Buddhist practice.
The second possibility is that ancient people didn't live long, and there were errors in historical records, which deified the sages who had made outstanding contributions in previous lives. According to the historical records of the Western Han Dynasty: King Mu ascended the throne, and it was fifty years in the Spring and Autumn Period. In fifty-five, Mu Wangli collapsed. ? Zhou Muwang acceded to the throne at the age of 55, and died after 50 years in office, with a life span of 105 years. And the Spring and Autumn Bamboo Book: It was sent to a hundred years since the week, but it has not lived for a hundred years. ? Although Historical Records is a unique school, it inherits the spirit of record, but in the era of underdeveloped book printing, it is inevitable that personal thoughts and imagination are mixed in it.
The third possibility is that there was no unified time measurement at that time, and the life span was normal. It is said that the immortal star? Peng Zu? I lived to be 880 years old, but why? Xiaohua? Calculate age: a sub-cycle of 60 days is one year old. Peng Zu is about 140 years old if it is estimated by converting 365 days a year. According to records, Peng Zu was calm, clean and healthy, and elegant? The elk horn is scattered? Dan medicine nourishes the body and can live to 140 years old. Do you know? Still the most important thing.
According to the present statement, there is also a basis for saying that the ancients were short-lived. In the later period of clan alliance, tribes often fought for territory, causing killings and waging wars. Where the war spread, there were barren and hungry fields everywhere. Civilians died of famine and fire, the population decreased and the quality of life declined.
In the period of unstable social order, diseases are prevalent and there are no high-level medical conditions. Even if people like this catch a cold, it is a very serious disease for people at that time, and it is easy to lead to death, so the life expectancy gradually drops below 50 years old. A great man like Zhuge Liang, who was still alive, died at the age of 54.
The short life span of ancient people, poor living environment and low living conditions are the main reasons. In the face of powerful natural disasters, people can only pray to heaven. Without high technology, they don't even have efficient transportation to escape. Even the luxurious Emperor Wu of the Han Dynasty failed to keep up with the current production level. He lived 7 1 year, which was a long life at that time.
In short, from the perspective of life and health, human beings may live to be one hundred years old or even longer. The length of life is limited by many factors, such as social economy, medical and health care, human psychology and so on.
