Why can t people live to their natural lifespan?

Why is it that human beings have such a short lifespan and cannot live forever? Scientists have finally told the truth!

If a person dies of natural causes, it is not a disease, and how many years of life can he live is a natural death.

Hello, I am happy to answer your questions, in general, the natural life expectancy of normal and healthy health should be at least 80 years old or more than 30,000 days old, less than 80 years old or 30,000 days old and dead should belong to a small number of unhealthy bodies, if it can be more than 100 years old, even if it is ultimately a non-aging cause of death, it is considered a very small number of longevity. Natural death here refers to death that is not caused by non-aging causes, but includes death from illness directly caused by aging.

Summary. Hello, if a person dies a natural death, it is not a disease, and it can have a lifespan of about 150 years [eat whales] If a person dies a natural death, it is not a disease, and how many years can the lifespan be a natural death.

Hello, if a person dies a natural cause, it is not a disease, and it can have a lifespan of about 150 years [eat whales] in an ideal state without disease and disaster, and the living conditions are particularly good, etc., all the guesses are done if they are the best, these are difficult to achieve, and the longest-lived person in the world is currently more than 130 years old.

Note that I am referring to the maximum life span reached theoretically, and those who are more than eighty or two hundred years old do not need to believe it, and there is no reliable proof of it. Theoretically, all conditions such as no disease and no disasters are very good, and the average life expectancy should be about 120 years old.

Zoologists have found that healthy animals living in nature generally live seven times longer than their developmental period. According to this law, a person should live to be about 150 years old. However, it can be said that there are very few people in the world who can live such a long life.

So why don't humans live their natural lifespan? This is a complex issue. There are many reasons for this, such as:

Human living environment, social activities, nutrition, diet, psychological activities, etc. In addition, scientists believe that the unique physiological characteristics of human beings are the key to limiting human lifespan

1) Human walking upright, compared with animals with limbs and prostrate walking, greatly reduces the range of motion of the locomotor system (bones, joints, muscles, ligaments) j, increases the load on the spine, and the position of the brain and the high movement of the head 'are easy to cause ischemia, hypoxia, and eventually lead to brain and cardiovascular diseases in humans.

2) Unlike other animals, humans mainly breathe in the chest, which greatly limits their lung capacity.

3) Compared with animals, humans exercise much less, coupled with an increasingly comfortable living environment, which greatly reduces the blood circulation function of humans, which is also the cause of brain and cardiovascular diseases. In addition, the progress of material civilization has made human beings more and more "tired of eating", and their ability to swallow and digest have deteriorated. Scientists have found out these reasons for the "short life" of human beings, so we "do the opposite", for example, exercise to increase lung capacity, exercise more, eat more coarse food, etc., may be a great secret to longevity!

Birth, old age, sickness and death are all regular, and even changing human genes will greatly attenuate the speed of human evolution, without any benefit. If human beings really live to be 1,000 years old, then the world will change a lot. At that time, human beings not only have no joy of life, but feel very boring, because many things have been experienced when they are young, so when they reach old age, they will have no desire to do things, and they will lose their desire to live over time.

So I don't think we can make human beings live to be 1,000 years old.

I don't think so. Because the U.S. survey shows that the human lifespan is participating every year. If people in the future can live to be 1,000 years old, then maybe 200 years old can be considered teenagers, learn more things, and technology is more developed.

There should be a limit to the life span of human beings, and the time that everyone lives is actually different, if people can live to 1000 years old in the future, the earth may be **, and the earth will definitely not accommodate all human beings.

There is a limit, and some people will die after living to be 120 or 30 years old at most. Then the world will be chaotic, and people's lives may be very boring.

Scientific research has shown that the normal lifespan of human beings should not be less than 100 years. When scientists study mammals, they have found that their maximum lifespan is equivalent to 5 to 7 times that of the growing season.

Humans are also mammals, with a growth period of 20 to 25 years, and a natural lifespan of 100 to 175 years.

In fact, there are still very few people who actually live more than 100 years old, which is caused by people's lack of health care and lack of attention to health care.
