Why are 73 and 84 years old two hurdles for the elderly? Is there any basis?

As the saying goes, "seventy-three, eighty-four, the ghost king doesn't invite himself." This means that more elderly people die in these two age groups. But strangely, many old people did die at these two ages. Why?

Influenced by Confucian culture, it is said that Confucius died at the age of 73 (55 1- 479 BC) and Mencius died at the age of 84 (372- 289 BC). One of them is a saint, and the other is a saint in the history of China. Confucius and Mencius are famous thinkers, politicians and educators, and the most important thing is the founder of Confucianism. Their influence on the Chinese nation is deep-rooted and goes back to ancient times. Because these two saints were taken away by Ye Yan between 73 and 84, it is even more difficult for ordinary people to cross this hurdle.

Modern medical research shows that people's life activities are periodic, about 1 1 year, with corresponding highs and lows, and 73 and 84 are just at the end of two cycles, which is the lowest stage in that cycle. In fact, 95 years old is another low point, but it is rarely mentioned because there are so few elderly people who live to 95 years old.

He is old, besides taking care of his life, he should pay more attention to the spiritual world of the elderly, and try not to have fierce emotions such as anger, melancholy, sadness and excitement. Calm mood is the most important factor for the elderly to live longer. Just like a tree, it is a new experience to die peacefully after experiencing the immature bud and the magnificent foliage.
