What is the limit lifespan set in human genes and how do scientists calculate it?

Through a large amount of data, the data mainly includes the life span data of mammals, and then carefully analyzed and summarized, and finally a relatively rough data is obtained.

Scientists make calculations based on the health of human cells, and the type and length of cells in each human body are different.

What is the ultimate dream of mankind? Some people say that it is to go to the sea of stars, rush out of the galaxy, and colonize the whole universe. It is not denied that this is indeed one of the ultimate dreams, but the ultimate dream of human beings at the bottom is to overcome birth, old age, sickness and death.

If there are two choices in front of you: humanity becomes the most powerful civilization in the universe, or you yourself live forever.

With the further development of bioscience and the deeper understanding of genes, the average life expectancy of human beings as a whole will definitely become longer and longer in the foreseeable future, but eternal life is a thing with no end in sight. For the human race, the life expectancy of individuals is actually very different, some people are born to die, some people live a long life, regardless of the accident, what determines the life span of human beings?

Generally speaking, many people are more inclined to think that there is a closer relationship between life expectancy and lifestyle habits, and that healthy diet, work and rest, exercise, and mental state are the keys to a good body, so they will live longer. The deep-rooted concept has also brought about a huge user base in the big health industry and the unshakable stability of this market, and in fact, scientific research has found some other correlations.

At the same time, their living habits are not too significantly different from those of ordinary people, whether it is diet, tobacco and alcohol or exercise, these people do not carry out any special maintenance and activities in their daily life, but their life expectancy is mostly in the range of 95-122 years.

In the end, such a conclusion was reachedThe lifespan of sheep is related to the length of telomeres, not whether they are intact or not. The length of telomeres depends onGenetic inheritance,And the degree of intact andAcquired environmental factorsThe impact is related. Since the length of telomeres is closely related to the health of the organism, it is even saidIts length can represent the length of the life of the organism.

Therefore, the results of the sheep study can be found by analogy with humansOur lifespan may be predestined at birth. We maybeIt cannot be "opposed" to the genes in the body, so the length of life may beBorn with a beltYes, some people's "blood bar" is relatively long.

The most direct factor influencing human lifespan is genetics, that is, how long a person can live is largely determined by the moment you become a fertilized egg. We human beings are simply not able to increase the length of our lives by our own subjective will.

In this life, there is only one thing that all of us can be 100% sure of, and that is that death will come sooner or later. Every human being is on the road to death from birth, and we are all creatures born to die. We can't control how long we live, just like we can't decide how long we live.

This is normal, according to the theory of biological evolution, the growth of a genetically determined organism will definitely be affected by the environment.

I don't think so, human life is in their own hands, as long as they can develop particularly good habits, they can live for a long time.

I don't think that's true, as long as we live a very healthy life, whether it's in diet, lifestyle, as long as it's in a very healthy way, we can change our genes.

It is about 130 years old, and it is related to the genetic factors of eating habits, so you must ensure adequate sleep, strengthen exercise, adjust your mood, and insist on doing physical examinations.

At present, the limit of human life is more than 100 years old. It depends on the way of life, on the mode of life, on the environment of life, on what you eat.

Can genes determine when a person dies? Does birth determine the length of life? These are almost all topics that people have been discussing since ancient times, and scientists are also actively studying this topic, but no conclusive evidence has been found until now, for human beings, life is limited, but is the end of life really the end, and can people perceive death after death?

On the other hand, more people are also studying human genes, whether the difference in life expectancy is due to the difference in genes, it is understood that the United States initiated a study together, and found that the life expectancy of human beings seems to be affected by genes in more than 1,200 samples, but genes are not static, in a long life, human genes may change, and this may also affect human lifespan.

Some studies have pointed out that after death, human hearing is the last to disappear, so 30% of people can perceive death, but not everyone will be like this. So do genes completely affect longevity? Scientific research has shown that genes can affect a person's lifespan and can determine the time of partial death, and not all deaths are determined by genes.

As the living environment changes, it is also possible for human genes to change. In terms of genetics, in human death, genes can only determine 30 factors, and the remaining 70 are caused by the external environment, such as personal living habits, environmental factors, and even accidents.

Of course, everyone wants to live a long life, so can genetic technology be used to change the length of life? This problem has been studied by scientists for a long time, although there is a certain possibility, but it cannot play a role in practice, because the degree of impact of genetic changes on the human body is incalculable, but this experiment has the effect of prolonging life in animals, with the development of science and technology, perhaps one day there will be this result.

So is there really a longevity gene? From a genetic point of view, longevity genes exist, this gene can affect human stem cell regeneration, and can slow down the rate of human aging, these genes are not only specific people, but all animals and people exist, but only some people can make full use of it, of course, human genes are very powerful, but the most important thing is to have a good lifestyle, correct bad habits, so as to make better use of the body's internal longevity genes.

There are different definitions of death, and it is possible for a person to be conscious at the moment of death, but in science, the heart stops beating and it means death, and each has a different definition. But for human beings, life is limited, regardless of whether genes can prolong life, face life positively, with the progress of science and technology, human beings may extend their lifespan, but it is more important to do meaningful things in a limited time, if one day you can prolong your life, will you choose?
