In the history of human civilization, old age, sickness and death is a normal thing, the ancient emperors have unprecedented glory and wealth, they are not willing to accept the old age, sickness and death, and began to think of ways to extend the life span, immortality. However, human beings can live for a long time, in fact, there is no living very long people, it is understood that only the mythological stories of people can have thousands of years of life, in the United States science and technology magazines had been raised the question of how long is the limit of human life expectancy, for this topic many people said very doubtful.
The average life expectancy has increased by 20 years
People nowadays are very confident in science and technology, and also believe that science and technology can give people a long life. So is technology really so advanced that it can change the fate and lifespan of human beings? According to Liu Cixin's work, human beings can live to be more than 300 years old through genetic fabrication and entering hibernation, so what meaning is there in life to speak of. Since the technological revolution more and more people are most concerned about how long they can live.
Because they feel that now and in the ancient times, it has been different from the past. Human beings can change their destiny through technology, and with the advancement of genetic engineering, it seems that extending their lifespan is no longer a concern. However, judging from the big data, the average life expectancy of human beings in the past was probably under 50 years old, and nowadays there are a lot of people who can live to be over 70 years old, and that's under the premise that there is no disease. Because if you go by true life expectancy plus those who die of disease, then there are far more people who die at 50 than those who die at 70.
The limit of human life expectancy as long as 130 years compared to human life expectancy is higher than ever 20 years, because with the level of technology, people's quality of life is also higher and higher, the medical means is also very advanced, coupled with the human genes of the exploration, are the key factors in the delay of the human life expectancy. More scientific and technological community that the key factor in human life span lies in the cell, if there is a person human cells can be interfered with by external forces, able to achieve cell replication to extend the regeneration, unlimited division and reproduction, then human beings can achieve eternal life, of course, this is just nonsense.
In the eyes of scientists, the limit of human life is only 130 years old, the average limit of life is only 77 years old, to reach the age of 130 years old, no matter how high the technology can not be delayed its life. But for ordinary people, live a long time is also quite bad, only the rich want to live forever. In fact, we do not need to take the life expectancy how long to see how important, because people live not only for life, but more importantly, affection, friendship, love, and contribution to society.
Birth, old age, sickness and death is the norm, we should not focus on how to extend life, but more should focus on, affection love friendship, people's lives will be colorful, so that life is more valuable, and ultimately will not fall what regret. As Kazuo Inamori said, life is a soul training.
