Immortality is a super wish that everyone wants to realize. With the continuous breakthrough of science and technology, mankind may realize this wish in the near future.
In 2009, Russian scientist Blau Skov excavated a special bacterium named Bacillus F in Siberia, which has a history of 3.5 million years.
By 20 15, Blau Skof continued to study this kind of bacteria and found that the cells of Bacillus F were still self-repairing and alive.
So Blau Skoff continued to take the bacteria to the "old" old mice for experiments and injected the bacteria into the mice. Miracle appeared, and it was found that the vitality of the old mouse was actually restored when it was young, and it was rejuvenated to a certain extent.
Later, we continued to use Bacillus F to do experiments on more living bodies, and finally we did experiments on human blood cells. The result is unbelievable. This kind of bacteria can promote cell regeneration and division and strengthen the immune system.
After many experiments, Blau Skoff decided to do the experiment himself. He gave himself an injection and found that he really became younger and healthier than before.
What does this experiment show? It shows that aging can be controlled. It is natural for human beings to get old after birth. If we want to live forever or delay aging, what is the principle of human natural aging?
Only by seeing the essence of things clearly can we fundamentally solve the problem. Let's discuss this difficult problem together.
There are many factors that will affect people's life span. There are two well-understood factors.
The first factor: aging is due to the aging and pathological changes of DNA, which leads to the inability of cells to divide and regenerate.
During the neonatal death cycle, cells constantly produce something called lipid free radicals, which is "human waste". This kind of garbage is very harmful to human body and will cause cancer.
As people get older, they will accumulate this kind of human excrement. This free radical will accumulate on the cell membrane and accumulate more and more. But also constantly attack the fatty acids on the cell membrane to produce lipid peroxide, which is very toxic and will destroy the lipid, protein and nucleic acid of cells.
When the cell membrane is destroyed to a certain extent, the cell stops metabolism and does not regenerate.
Besides aging, it can cause many diseases, such as heart disease, Alzheimer's disease, Parkinson's disease and tumor. Therefore, with the growth of human age, the probability of suffering from senile diseases such as heart disease and tumor will be higher and higher, because the free radical garbage in the body increases with age.
Is it possible to get rid of this free radical rubbish? The answer is, of course, yes. Excessive free radicals accumulated in human metabolism can be eliminated by taking vitamins.
This is why the body's own vitamins will continue to be consumed and need to be supplemented regularly. Therefore, eating more fruits and vegetables to supplement vitamins can clear the metabolic waste of human body, keep healthy and maintain youthful vitality.
The second factor: telomere loss on DNA leads to aging,
Telomere is a sequence on DNA, which protects DNA. Every time DNA is copied, telomeres will decrease, and eventually telomeres will be exhausted and discarded, and cells cannot replicate.
Scientists predict that telomeres will be used up when cells divide 50 times.
For the sake of understanding, let's make an analogy. Telomeres are like the only inkpad of a radish stamp, and DNA is the words on the stamp. After stamping for 50 times, the inkpad will be exhausted and dried up, so the radish stamp will be scrapped.
If human beings want to live longer, the only inkpad problem that needs to be solved is to increase inkpad, that is, to increase telomere sequence.
In a more popular way, telomere is like a "clock", which can count cell division and control cell aging. The life span of cells is determined by telomeres, so is the life span of people.
At this point, many people will naively say that since we know that the number of cell divisions is determined by telomeres, then we can make telomerase to activate telomeres, and immortality will be realized.
In fact, scientists at that time also thought so. The results showed that after telomerase activation, the number of cell divisions increased, but it could not be controlled. Cancer happened, cells did not die, but people were gone.
There is a study on human life span, which is called Havrick's limit theory. The conclusion of this theory is that human organs are composed of cells, and the average life span of cells is about 2.4 years, which means that human organs should be replaced every 2.4 years.
It has been said before that the maximum number of times a human cell divides is 50, and 2.4 times 50 equals 120. According to this theory, a person's normal life span should be 120 years old. However, at present, few people can live to be over 100.
So what is the way to live long and even live long?
In addition to what we said earlier, Russian scientist Blau Skov killed Bacillus, and there are many others.
According to the current statistics, the more common ones are: stem cell therapy, nano-robots entering human cells, and building construction teams, just like building houses, which can restore various organs and functions of the human body, cope with diseases and prolong life.
In addition, 3D organ printing can be used to replace aging organs and prolong life.
The most important thing is to separate the brain from the body and make a brain chip to keep consciousness alive and realize eternal life.
However, for ordinary people, these expenses are very expensive, but I can't do it, so if you want to live long, you must first become rich. Li Ka-shing, Buffett and others. Why can they live so long? Do you understand anything?
Besides becoming rich, ordinary people have another way to live longer and longer.
Why? Because there are many ways to achieve immortality, but every technology is now at a critical point. When the technology breaks through and can be popularized to the cost that ordinary people can afford, it will not be perfect.
Moreover, with the development of science, this time will not be too long, maybe several decades later. So, eat more vegetarian dishes and exercise more, keep relaxed, keep your mouth shut and spread your legs. Longevity is not a dream @ Don't just wait until the day before the technological breakthrough, it will be a tragedy.
To sum up, in the future, human beings can definitely live forever. When technology develops to a certain stage, humans can even customize their bodies, organs, looks, heights and so on. They can live for a long time and wait for that day.
Finally, it ends with a sentence by the English poet Tennyson in his poem Ulysses: life will be consumed by time and weakened by fate; But we still struggle, explore, search and never give in. So, life goes on, I wish you good luck and longevity!
