Why is there a saying that "a thousand-year-old king is a turtle for 80 thousand years"?

"Thousand-year-old turtle, ten thousand-year-old turtle" is an exaggeration, which means that turtles and turtles have a very long life. It's true. According to the observation and research of zoologists and turtle experts, it is found that turtles who eat plants generally live longer than those who eat meat and omnivores. For example, domestic turtles living on tropical islands in the Pacific Ocean and the Indian Ocean feed on grass, wild fruits and cacti, and their life span is particularly long, with 300 years.

Reason:

First, the tortoise has a unique body structure and physiological functions. The tortoise has a hard shell, so that its head, abdomen, limbs and tail can protect itself from the outside world. At the same time, turtles also have the habit of sleepiness, sleeping about 10 months a year, hibernating and sleeping in summer, so their metabolism is slow and their energy consumption is little. ?

Second, scientists have found that there is a clock about cell division in human and animal cells, which limits the algebra of cell reproduction and its life span. When human embryonic lung fibroblasts are cultured for 50 generations in vitro, it is difficult to continue, while turtles can reach 1 10 generation, which shows that the generation of turtle cells is closely related to the life span of turtles.

Third, zoologists and medical scientists have examined the heart function of sea turtles. After the turtle's heart is taken out in vitro, it can beat for 24 hours, which shows that the turtle's heart is powerful and plays an important role in its life.

Fourth, scientists believe that the longevity of the tortoise is also related to its breathing style. Turtles have no intercostal muscles, so when breathing, they have to move up and down under their mouths, suck air into their mouths and send it to their lungs. It is also because when it breathes, its head and feet stretch and its lungs suck one by one. This special breathing action is also the reason why turtles can live a long life.

Scientists also believe that turtles are excellent animal models for studying human life span. Therefore, further revealing the mystery of longevity of turtles will have important implications for the study of human health and longevity.

Because turtles had a good reputation before the Tang Dynasty, they were highly respected. Tortoise and tortoise are the same animal.

First of all, turtles can live on land and in water, which is beyond the reach of most animals.

Secondly, the turtle has a long life, and it is a kind of elephant turtle that lives on the islands in the equatorial region. It can live for three or four hundred years. Therefore, the ancient people thought that the turtle had a large activity space and long experience, which was a symbol of longevity.

Third, the tortoise is one of the ancient Four Spirits (Dragon and Phoenix Forest Turtles), and only the tortoise in the Four Spirits exists objectively in nature. Therefore, the ancients believed that the turtle was an intermediary between man and god, through which the will of the gods could be understood and the respect for the turtle could be blessed by the gods.

Fourthly, tortoise shell is an instrument used by the ancients to predict good or bad luck. Often burning turtles and observing their cracks will inevitably make people feel mysterious and awed.
