Can humans really live forever?

Human beings’ longing for eternal life has a long history, and different cultures and religions have their longing and pursuit for eternal life. However, so far, whether human beings can live forever is still an unknown mystery. Starting with the problems of biological cells, genes and mechanical soaring, this paper discusses whether human beings can live forever and the possible ways to live forever.

1. Biological cells: Are there "immortal cells"?

The human body is composed of cells, and in the process of cell division, growth, aging and death, human beings are getting old, sick and dying. If we can find an "immortal cell", can human beings achieve eternal life?

In fact, no real "immortal cells" have been found yet. However, scientists have discovered a cell with certain "immortal" characteristics-cancer cells. Cancer cells can divide constantly and proliferate indefinitely, but at the same time, they will also destroy healthy tissues and organs, leading to cancer. Therefore, cancer cells are not an ideal way to realize human immortality.

In addition to cancer cells, some organisms also have certain "not old" characteristics. For example, turtles can live to be over 200 years old, and whales can live to be hundreds of years. However, even these creatures will eventually die, but they will live longer than other species.

2. Genes: Is there a "longevity gene"?

In recent years, the development of genetic science has led people to believe that the goal of human immortality may be achieved through gene repair and transformation. In fact, scientists have discovered some genes that may be related to longevity, such as SIRT1, FOXO, mTOR and so on. These genes are involved in important processes such as cell repair and metabolism, and are closely related to the length of life.

For example, scientists found through experiments that by activating SIRT1 gene, the life span of experimental animals can be extended by more than 30%. At the same time, researchers are constantly looking for other genes that may be related to life span, trying to extend human life span through gene editing technology.

However, genetic science is still in the exploratory stage, and the development of related technologies is also facing various difficulties. At the same time, gene editing and repair may also bring some unexpected consequences. Four, other possible ways

In addition to the possible ways mentioned above, there are also some other scientific technologies and theories that may have an impact on human beings’ realization of eternal life.

Stem cell technology

Stem cells are cells that can differentiate into many different cell types, and the development of stem cell technology is considered to be a field with great potential. Scientists are exploring how to use stem cell technology to repair and replace human organs and tissues, thus prolonging life.

cloning technology

The development of cloning technology is also considered as a possible way to achieve immortality. Through cloning technology, human beings can copy an identical individual, thus achieving the goal of eternal life. However, there are still many ethical and moral problems in this technology, such as whether it will lead to human beings becoming commodities and so on.

artificial intelligence

Artificial intelligence is a rapidly developing technology, and its potential has attracted people’s extensive attention. Through artificial intelligence, human beings can better understand their own life process and mechanism, discover new treatment methods and drugs, and thus prolong their life.

For example, artificial intelligence can help doctors predict the disease risk and treatment effect of patients more accurately, thus improving the treatment efficiency and success rate. At the same time, artificial intelligence can also help scientists analyze and understand life science data faster, thus accelerating the development of new drugs.

However, artificial intelligence technology is still in the stage of continuous development, and more research and exploration are needed.

V. Conclusion

Although the realization of immortality is still an unknown mystery, the continuous development and breakthrough of science and technology make us full of expectations and hopes for the future. From biological cells, genes, mechanical soaring, stem cell technology, cloning technology, artificial intelligence and many other fields, human beings have been looking for possible ways to live forever.

However, we also need to maintain a cautious and awe-inspiring attitude, and consider its possible impact and consequences while exploring and studying. We need to seriously think about how to balance scientific and technological progress and moral norms and find a suitable balance point. Only in this way can we explore better.

Nine professions are about to disappear, and doctors may disappear in the future? Will all be replaced by artificial intelligence?

Introduction: With the development of artificial intelligence, more and more industries are being replaced by artificial intelligence, and many plots we see in science fiction stories have become reality, such as driverless and self-help shopping. The first thing that artificial intelligence replaces is simple and repeatable industries, and there are some industries that require few algorithms. Therefore, with the development of artificial intelligence, more occupations may be replaced in the future, and more and more workers will be replaced.

Now, some experts have evaluated and compared all professions, and compared their advantages and disadvantages and substitutability, thus drawing a conclusion that there may be nine professions completely disappearing from history in the future, including the doctor profession on which we are very dependent. How is this? Let’s take a look at the nine occupations.

I. Judges

This will happen in many international competitions now. There are no referees in the stadium, and there will be many high-definition cameras running around the stadium at high speed to record the competition process, which can not only record the most wonderful high-energy moments, but also prevent the contestants from breaking the rules. Therefore, in the near future, judges will also be replaced by machines.

Second, the translator

In this world, every country has its own language, which is a great thing. This is a splendid civilization in the world. Before, there was little communication between China and foreign countries, and foreign language learning was not taken seriously, so the foreign language level was very low. However, because the cultural level of our country has been improving, almost every young person can speak one or several languages now, and there is basically no obstacle to communicate with foreigners.

Nowadays, the translation software is very advanced. As long as what you want to express is input into the software, the software will automatically translate it, and even some software can read it directly. Therefore, in the near future, the translation industry may gradually fade out of people’s horizons.

Third, the programmer

Programmers are called "elites" in the network age. However, with the increasing intelligence of computers, various artificial intelligences have begun to rise. For example, ChatGPT, which is very popular recently, can automatically generate reports and write its own programs. The future programmer profession is still very dangerous, and it is likely to be replaced by artificial intelligence.

Fourth, the driver

In many sci-fi films, we can see that many vehicles in the future have been unmanned, and people can drive remotely through the network background. Although this sounds like a fantasy, in fact, the current driverless technology has been developed by technicians to be close to perfection.

When the vehicle is in an unmanned state, the vehicle can automatically avoid the surrounding dangerous objects and find the best path to reach the destination. If this technology is really popularized in the whole society, then the profession of driver may no longer be needed by society.

V. Firefighters

Now, with the development of science and technology, more and more scientific and technological equipment are used for emergency rescue and disaster relief. For example, if there is a fire, the drone can carry out fighting and rescue, and it can also use various electronic technologies to enter the fire center to detect signs of life. This rescue method can not only minimize the risk, but also minimize the casualties of rescuers. Therefore, in the near future, frontline firefighters may be eliminated.

Six, physical store sales staff

For example, in the unmanned supermarket that is very popular recently, customers can pay the bill by scanning the product code with a machine when they enter the supermarket. In addition, most large supermarkets have opened self-checkout counters now, which makes customers have a stronger shopping experience than traditional manual cashier, and there is no need to wait in line. Therefore, in the future, the sales staff of physical stores may be replaced.

Seven, assembly line workers

The continuous improvement of machine automation level has triggered a brand-new industrial revolution. Today’s production machines are highly intelligent, and many factories have realized full-line automatic production, and the industry of assembly line workers will soon be eliminated.

Eight, gas station staff

As we all know, the gasoline added in the current gas station is refined. The annual output of crude oil is limited, and it is an unsustainable energy source. At present, there is no substitute for crude oil. If there is no oil, there will be no gas station and no gas station staff. The survival of this position is closely related to the exploitation of oil resources.

Nine, the doctor

Now, when you go to see a doctor, you always use all kinds of equipment to examine the patient first, and then the doctor can treat the patient. If there are enough medical records in the medical database, patients can do self-help, and at the same time, the rate of missed diagnosis and misdiagnosis can be reduced.

Although it has not yet begun to replace doctors, "cloud consultation" has been carried out in some areas. Where the doctor industry should go in the future depends on the development level of artificial intelligence.

Summary: The above nine occupations may disappear in our society in the future and be completely replaced by artificial intelligence. These occupations can be realized by simple algorithms of artificial intelligence and are simple and repeatable. Compared with artificial intelligence, our most precious thing is our creativity and imagination, so if we want to be replaced by artificial intelligence, everyone should improve their abilities in these two aspects. In the future, there will be more and more industries that artificial intelligence can replace. Everyone should pay attention to job competition and beware of machine replacement.

Tevez revealed that he hated Sir Alex Ferguson and informed him to move to Manchester City before the Champions League final! Revenge on Manchester United and renege

Argentine star Carlos Tevez, nicknamed "The Beast", is an enhanced version of Wehorst, who can score goals and catch up with his own bottom line from the front line. However, because of the transfer, he finally fell out with Sir Alex Ferguson, and even raised the slogan "Sir Alex Ferguson rests in peace" after moving to Manchester City. Even now that he has retired, the 39-year-old Tevez still resents the way Sir Alex treated him at Manchester United.

Tevez was loaned to Manchester United in 2007, during which he performed well, scoring 34 goals in various competitions and winning two Premier League titles and the Champions League trophy. However, Tevez did not complete the permanent transfer to the Red Devils. In 2009, he joined rival Manchester City, where he spent the next four seasons. Tevez insists that Sir Alex Ferguson was the reason for his decision to move to Manchester City.

The Argentine Beast stressed that he wanted to stay at Old Trafford, but Sir Alex made a false promise to him. Manchester United didn’t buy him out, so he didn’t hesitate when he received the invitation from Manchester City. "I don’t need to think too much, because I am angry with Ferguson. Tevez told ESPN, "As a coach, he is a phenomenon. He has been teaching at a club like Manchester United for so long, but something happened between me and him. 」

Tevez explained in detail: "I was loaned to Manchester United, and finally he told me:" Manchester United will buy you out, but I will bring Berbatov. Don’t worry, I brought him in to compete fairly with you. We will talk to your agent and reach an agreement on the contract and transfer. But in the end, they didn’t call the broker, and nothing happened. Time is running out. They began to want to lower my price. Every time I play, I perform, and the fans shout names. This is a year-long digestion process. 」

According to Tevez, before the 2009 Champions League final, he told Sir Alex Ferguson that he would join Manchester City as a revenge for United’s reneging on their words in the past year. "I have more or less accepted Sheikh Mansour’s proposal. After the final, I will take a private jet to meet him in Abu Dhabi with my family and solve the contract problem with Manchester City. All this happened before Manchester United’s Champions League final," Tevez added. "The day before the Champions League final against Barcelona, I told him that I would join Manchester City. 」

Tevez started 18 games in the Premier League that season and scored 5 goals, which he was not satisfied with. In that Champions League final, Sir Alex Ferguson finally arranged for him to play as a substitute in the second half, playing 20 minutes earlier than Berbatov, but neither of them played a role. Barcelona beat Manchester United 2-0. "Ferguson kept saying that he was going to buy me that season, and then he brought in Berbatov and didn’t let me play in the league. "The beast vomited.

Tevez then added: "It was like a dagger for him to tell him before the final that I was going to join Manchester City. But it is also true for me, because I love Manchester United. But for me, he didn’t keep his promise for a whole year, and he made me miserable. It hurts me a lot because I love Manchester United. I like playing football at Old Trafford. Playing football there is like a bomb explosion. It gives me that feeling. Then the chief came, and they told me that they wanted me to be the standard bearer of Manchester City. He showed me the blueprint for the future, just like the club is today. 」

After the official transfer of Tevez, Manchester City released a controversial advertisement in the local area, in which Tevez opened his arms and the poster read "Welcome to Manchester". Tevez later made 148 appearances for Manchester City, scored 73 goals and assisted 35 times, which helped the team win the Premier League and the FA Cup. However, his time with the Blue Moon also ended in a broken relationship because of falling out with coach Mancini.
