Hello !

Bioorganisms age due to the fact that it is a genetic program, in fact, collapse, collapse of the organism. why does it exist? if the question "why" is generally appropriate ... exists according to the principle "nothing lasts forever under the Moon", a constant replaceability of the biomaterial is required. the presence of immortal organisms is essentially not required for evolutionary tasks. if you can think so.

From 70? you greatly overestimate it. only with very good nutrition and lifestyle, as in modern developed countries, people die at 70. Even in our country, the average life expectancy of a man is like 68 years. in the ancient world, where food was worse, where the environment was dirtier, where living conditions were more difficult, people did not always live up to 20-30. They did not grow old about this in the literal sense, they simply wore out earlier. only a few survive to 100. one in a million. so the lifespan record is just over 120 years.

Good luck and thanks for your question!

The civilization of society is to blame for early aging and early death. How, maybe, someone knows that Adam died at the age of 930, and at what age Eve died, until now, no one can say anything. Their children and grandchildren, too, have lived a healthy number of years. But with the development of civilization, gadgets appeared that gradually removed the previously necessary functions of the human body. For example: excellent vision, hearing, touch, smell, taste, third eye and others that we now do not even know about. Because of this, diseases associated with the degradation of Homo sapiens began to develop, and since modern medicine does not keep pace with the emergence of new incurable diseases, a person dies from them or from laziness at the age of 36 to 100.

The specific answer to your question: because this is the length of its telomere. Having studied what a telomere is, how it breaks down during cell division, everything will become clear to you. https://zen.yandex.ru/media/sciencecafe/kak-dolgo-liudi-mogut-jit-5b2ba5e3c8dfbc00a8551b9e

the way you use an enzyme like telomerase (which does exactly that) is that you could be the author and creator of an immortal organism.

Premature aging can start at an early age. This is a severe disease Pts, called Progeria. Still people who suffer from it are distinguished by dwarf growth and physique. example.

Bioorganisms age due to the fact that it is a genetic program, in fact, collapse, collapse of the organism. why does it exist? if the question "why" is generally appropriate ... exists according to the principle "nothing lasts forever under the Moon", a constant replaceability of the biomaterial is required. the presence of immortal organisms is essentially not required for evolutionary tasks. if you can think so.

from 70? you greatly overestimate it. only with very good nutrition and lifestyle, as in modern developed countries, people die at 70. Even in our country, the average life expectancy of a man is like 68 years. in the ancient world, where food was worse, where the environment was dirtier, where living conditions were more difficult, people did not always live up to 20-30. They did not grow old about this in the literal sense, they simply wore out earlier. only a few survive to 100. one in a million. so the lifespan record is just over 120 years.

why not at 30? there is a definite approximate service life of all organs. provided that they exist in acceptable conditions, without injury, without poisoning with something like alcohol. so the heart is about a billion beats. creatures with a fast metabolism, such as hummingbirds - live only 9 years. turtles with a slow metabolism, energy saving, live up to 200 years, longer than humans. a person among all other species lives long enough, but the overall figure is closer to the average, there are bioorganisms that live longer.

For a long time, a person could start having children from about 16 years old. Further, with an interval of 3 years, a child appeared in a pair who needed up to 12 years of rearing. This is the first independent child at least 28 years old and then after 3 years. If they live and don't die of disease. And it was very noticeable - it didn’t live, probably about half or even less. That is, reproduction is 28 + 3 + 3 + 3 = about 37 years. Well, roughly about 40 years. (depending on the intensity of the risk from predators and diseases).

This is the biological early limit of aging - if some genes caused the body to break down earlier - they simply did not have time to reproduce - after a few generations they were purged from the gene pool.

But those who survived this threshold have already acquired more or less enough offspring so that the genetic "time bombs" could be triggered without interfering with the transmission of the genes that cause them to the next generations.

Genes , which would cause greater longevity, of course, on average in plus, but this plus is less and less. The individual is more and more likely to die from an accident, predator or disease by a certain age. Genes that would program death not at 100, but at 200 - could actually manifest themselves less often - up to this age (100 years), for natural reasons, very little survived in those days (for reasons not related to aging) - respectively, pressure on the genes of "clock bombs" -minimal.

And the fact is that individual cells, if they have the opportunity to immortality, can be terrible for the body - because of one breakdown in the control of division, they can begin a cancerous transformation - to share non-stop, growing a fatal tumor for the body. Cells in the human body for a life of up to 100 years are of the order of trillions ... the probability of cancer breakdown turns out to be significant. Therefore, "time bombs", in particular, limiting the number of divisions of individual somatic cells can be very useful, limiting the ability of individual cells to divide uncontrollably - a tumor that has started to grow cannot overcome a certain limit of divisions. At least one of the "time bombs" works like this.

In general, the more difficult it is to successfully raise a child to his independence, the later the aging. - the higher the early aging limit

The higher the risk for an adult to die - the earlier aging - the lower the upper aging limit and vice versa.

In this case, species without natural enemies can become long-livers.

Something like this.
