Scientists have discovered the secrets of male sheep longevity, or they are suitable for human beings, but they are extremely tangled

For life, aging and death are an inevitable process. Therefore, since ancient times, people have wanted to figure out what the essence of life is to achieve the purpose of longevity.

For example, in ancient times, Qin Shihuang sent Xu Fu to lead the three thousand boys and girls to go to the sea to find a pitch of spiritual elixir. He hoped that he could live forever. In modern times, with the improvement of science and technology, people hope that they can live forever and extend their lives through scientific methods. However Unfortunately, humans cannot break through the limit of life at all.

According to the Guinness World Record, the longest life is only 134 years old. So, is there really a secret to increase life? Studies have shown that scientists have found methods from Xiongyang, which may be applicable to humans, but this method is extremely tangled.

The secret of the longevity of male sheep -castration.

In many pastures in New Zealand, the underage male sheep will be castrated, because they find that the castrated male sheep is not only docile, but also more longevity, but also a little longer. Get more years of wool.

For example, the sheep named "Starick" in the New Zealand ranch was castrated after being castrated. If you live 16 years old, you need to know that the average life expectancy of the sheep is only 10 years old. What causes the castrated sheep longer than the normal sheep's life?

In July 2021, Victoria's team of Victoria University of New Zealand launched a series of experiments on the above phenomena. Among them, in order to observe the aging of the sheep's DNA, scientists used a "Epico Heritage Clock" in the study. Technology (this is a genetic test for biological age).

The castrated male sheep and the undesirable female sheep were tested, and they found that the castrated male sheep's DNA methylation model became more and more similar to the female sheep!

Originally, due to the DNA methylation model in female animals, the life expectancy of female animals in the natural world was generally longer than that of male, and the male sheep after the castration exactly "inherited" this advantage. The lifetime of male sheep should be longer, about 60%extended. In short, the male sheep will live longer after castration.

In order to make the data more rigorous, the researchers analyzed the data of a large amount of animals, and they still got the same result: the aging speed of animal aging after castration was slow. In this regard, scientists believe that male hormones, estrogen hormones, and life span in biology have a clear connection.

Through the above studies, researchers at the University of Otto University in New Zealand also proposed a bold conjecture that since the castration can delay the life of the sheep, can humans delay life by using the same principles?

Most people put this answer on the eunuchs in the ancient palace, because the life expectancy of eunuchs is indeed a little longer than that of ordinary men's life span, but this is only one -sided, and the conclusion is unscientific at all.

Even if it is really applicable to humans, the price that can be paid is a bit too large, because the palace is an insult for a normal man, and it will even cause their personality incompleteness. I believe it is for whom, this is all of this, this is all of them. It is a very tangled choice question.

Human life is limited.

Human life is long and short, but in all, they are limited. Its average life span is 70-80 years old. The centenary elderly people are very rare. In order to pursue a longer life, many people are looking for a way to live forever. Crack the mystery of life.

Scientists have found that the length of human life depends on telomeres. Many people may not have heard of it. So what is telomere? At the end of the chromosome of each organism, there is a substance called "telomere";

With the division of the cells, the telomere at the end of the chromosomes will also be shortened. When the telomere cannot be shortened, it means the end of life. Life is still long. On the contrary, the shorter the length of the telomere, the shorter the life.

In addition, in different organisms, the number of telomeres is different. The average body cells of our human beings are split once in two years, and the telomeres can be shortened by about 56 times. This means that the upper limit of human life may be only 120 years old. Essence

It can be seen that starting from the moment the life is born, everyone's life span has been decided. There is no need to be too strong, but it still needs to develop good living habits, because telomeres can be "overdrawn", such as smoking and drinking. Study in bad habits such as staying up late will reduce the activity of telomerase and accelerate the process of life.

Finally, research shows that estrogen has a protective effect on telomeres and provides telomerase activity. Therefore, in mammals, female life span is usually a little longer than male.
