Is there a theoretical upper limit to the lifespan of humans?

There is a theoretical upper limit, and mammals live 7 to 8 times as long as they are sexually mature. In the 2016 study, Jan Vijg, a molecular geneticist at the Albert Einstein College of Medicine in the United States, and colleagues analyzed global demographics over the past century and confirmed that the maximum age has remained around 115 years since the mid-1990s. Based on these results, the authors concluded that the natural age limit for humans is 115 years, and that the probability of people surviving beyond 125 years is less than 1 in 10,000.

Maarten Pieter Rozing, a professor at the Centre for Healthy Ageing at the University of Copenhagen in Denmark, wrote a rebuttal to this, saying, "They have taken it to the extreme: there is a limit to human lifespan. I believe that an extreme proposition should be subject to strict scrutiny.

There is another explanation that [maximum age] is simply increasing over time, and that the decrease in [life expectancy] that we observe is actually a false finding based on visual inspection and statistical methods that should not be used in this way. According to Nick Brown, a PhD student at the University of Groningen in the Netherlands (co-author of another rebuttal), one of the problems with the study was that the researchers split the data set in that year after reviewing the data and seeing that there might be an upper limit on the maximum age in 1995, and then tested the same data to see if this was the case. "Obviously, they thought they had discovered a pattern, and then they made up a theory to explain it," he said.

Subsequently, in the blink of an eye, the data was in line with this theory--- of course, because this theory was obtained from this data. This is a fundamental shortcoming in the conduct of scientific research. ”<

Of course, not to mention theoretically, there are in practice. From a physical point of view, entropy is always moving in the direction of increase, which means that the general trend is always from order to disorder. Organisms, like inorganic bodies, have a higher and higher degree of disorder from the very beginning, which can be simply understood as the process of aging.

There is no light bulb that will shine forever. The purpose of repairing a light bulb can only be achieved unless the process of aging is fully grasped and external intervention is given. Siegfried Hekimi, a biologist at McGill University in Canada, said that when he and his colleagues reanalyzed the data, they found that it did coincide with a variety of different lifetime trajectories, including some trajectories with a peak behind them and others without a peak at all.

"These data are consistent with a lot of other [longevity trends], and most of them mean that there is no significant limit to longevity at this time," Hekimi said. ”<

Longevity research has only begun to be scientific in the past 100 years; In the past 10 years, breakthroughs have been made in longevity research. Professor Dieter Prog told reporters that German scientists spent 15 years investigating 576 centenarians and found that the average age of their parents at the time of death was 9-10 years older than the average person. Therefore, scientists believe that the genetic factor of longevity is very important.

At present, he said, longevity research has become a cross-disciplinary and rapidly developing research subject. According to European scientists, aging is a multi-gene complex regulatory process, which is manifested by changes in chromosomal telomere length, DNA damage, DNA methylation and cellular oxidation. The combination of these factors affects the length of life.

After research, it has been found that the upper limit of human life expectancy can reach 150 years, and many people are very curious, what factors can determine the length of human life? I think it is not only related to the living environment, but also the genetic and psychological factors, as well as our daily food safety

1. Environmental factors.

I don't know if you have heard of it, there is a longevity village in China, there are many elderly people there, all of them are more than 100 years old, this is mainly because the local living environment is very good, with fresh air and the most suitable environment for living, most of the place is covered by vegetation. On the contrary, there is also a cancer village in China, because the living environment there has been polluted, so the residents are frequently suffering from cancer, which is not suitable for human beings to live there.

2. Genetic factors.

Yes, you read that right, the longevity of humans is indeed related to genetic factors. Studies have found that if a person's lifespan reaches 70 to 85 years old, then there are many family members in his family who generally live longer. If a person's lifespan does not exceed 50 years, then the average life expectancy of his family is not very high.

Of course, this is not fixed at all, after all, after a person gets married and has children, the child's genes will also change due to the union of two people.

3. Psychological factors.

As the standard of living is getting better and better, the pressure of life is relatively greater. Some people like to do things and start to get angry when they encounter things, and some people work under great pressure every day and often stay up late and work overtime, which will directly affect a person's lifespan. So if you want to live longer, it's best to be able to let go of your mood, don't dwell on one point, and remember not to get angry all the time.

Fourth, life factors.

Many young people always stay up late unscrupulously, have to eat another supper before going to bed, and do not eat on time, which can easily affect our personal health problems. Therefore, we should maintain a good schedule and eat on time. Try to stay away from tobacco and alcohol, and eat more fresh vegetables and fruits.

5. Food factors.

Therefore, additives are allowed by the state, but if you often eat a large number of additives, it will definitely not have any benefits for the body. Coupled with some unhygienic food safety problems, these will affect their own health.

The determining factors are the food eaten, the pleasure of the state of mind, and environmental factors, all of which affect the length of human lifespan.

It is the genetics and lifestyle of human beings, and the impact of these two aspects is very large, and it will affect them together.

The factor that determines the length of human life is human health problems, if a person is tired and the body is particularly healthy, then the natural life expectancy will be very long, on the contrary, if a person's body always has various problems and diseases, then naturally the life span of this person will be shortened a lot.

Longevity is almost everyone's dream. From ancient times to the present day, emperors and mortals alike have hoped for a longer lifespan, even immortality. However, even today's medicine is very well developed and wants to expand itself.

Longevity is still a very difficult thing. We just know that we have to maintain a balanced diet and exercise hard. This is the most basic thing you need to prolong your life.

Under normal disease-free conditions, what is the ultimate life expectancy of human beings? Actually,So far, scientists have discovered three methods of calculation.

First of all, the first one is to useGrowth cycleMake the calculations. Normally, the human growth cycle is 1 to 20 years old, that is, 20 years. At this multiple, mammals typically live about 5 to 7 times the growth cycle.

If it is 100-140 years old, this figure is quite reasonable, because centenarians are still there today.

As a rule, people do not suffer major injuries in their lives, immunity is normal, and there are no problems with his lifespan of more than a hundred years. However, with the current pace of life and eating habits, the human body will get sick to a greater or lesser extent.

Human development is unlimited, life expectancy is limited. When the water blue star people (earthlings) will walk out of the water blue star (earth) and become a qualified civilization, the god-level civilization god clan will consider increasing the life expectancy. - Divine Language+++ Note:
