It is said that 73 and 84 are the threshold of life and death. What does this mean?

"73, 84 is a hurdle for life and death" comes from the folk saying that "73-year-old, 84-year-old, the king of hell doesn't deserve it", which is an old saying. Without saints, you can't live. In fact, this proverb has no scientific basis, but it has an extraordinary origin.

In fact, this has something to do with the death of two ancient saints in China, Confucius and Mencius. Confucius was born in 55 1 year BC and died in 479 BC. He is seventy-two years old and seventy-three years old in name only.

Mencius was born in 372 BC and died in 289 BC. He is eighty-three years old and eighty-four years old in name only. Because the ancient people's ages were calculated in nominal years, Confucius died at the age of 73 and Mencius died at the age of 84, so there was a saying that "73 and 84 are a hurdle for life and death".

Biologists estimate human life span according to the number of animal cell divisions. The normal life span of human beings should be above 100 years. Some biologists believe that the maximum life span of a mammal is 8- 10 times that of its sexual maturity.

Although people can't live forever, as long as they are in a happy mood, have a proper diet, have a proper rest, live regularly and seek medical treatment as soon as possible, they can completely delay aging through nursed back to health, thus achieving the purpose of prolonging life. With the development of science, the improvement of living conditions and the strengthening of physical exercise, the life span of human beings will undoubtedly continue to grow.
