Dream of eternal youth and immortality: What new research has shown


Biologists’ research puts – hopefully temporarily – the hopes of a real “stop” in the aging process. However, the maximum expectation of human life has increased from the middle of the 19th century until today at an average annual rate of about three months.

According to new international scientific research, humans can not significantly slow down the rate at which they age and die, because there seem to be insurmountable biological limitations for such a thing.

In other words, eternal youth and immortality will probably remain what they have always been: myths.

Humans will probably never – in spite of scientific progress – become immortal or, at least, Mathews.

The maximum life expectancy of human life has increased from the middle of the 19th century until today at an average annual rate of about three months. This finding has led some to be optimistic that humanity has the potential to overcome old age – or even death – in the long run.

Research – Hundreds of billions of dollars a year

For years, many scientists around the world – with the support of governments, businesses and investors – have been pursuing the dream of slowing down or even reversing the aging process with the help of genetics, artificial intelligence and other methods. Today, the “industry” spends around $ 110 billion a year, an amount that is expected to jump to $ 610 billion by 2025.

But a new international study suggests that the dream is unlikely to come true. Researchers from 14 countries, led by Dr. Susan Alberts of Duke University in North Carolina, who published their findings in the journal Nature Communications, according to the British Guardian, examined the so-called “steady aging hypothesis”. , according to which a species ages at a relatively constant rate.

Reduction of youth deaths

Scientists compared evidence of births and deaths from humans and other primates, finding that there is a general pattern of aging and mortality common to all species. “Our findings support the theory that, instead of slowing down death, more people today are living longer thanks to a reduction in deaths at a younger age,” said Jose Manuel Aburto of the Leverhulme Center for Demographic Science at Oxford University.

“This means,” he added, “that there are biological rather than environmental factors that ultimately control longevity.” If the statistics are confirmed, people live longer, as their health and living conditions improve, resulting in increased longevity in an entire population. “Nevertheless, a sharp increase in deaths is clearly visible in all species, as the years go by and aging comes.”

How far can we go to live

The ongoing scientific controversy over how many years humans can finally live – with the help of science and technology – has divided the scientific community for decades.

The new study analyzed mortality data across a wide range of species, both within each species and comparing them. The resulting picture is more or less the same:

A high risk of death in early infancy, which declines rapidly in childhood and adolescence, remains steadily low in early adulthood and then steadily increases as the individual ages.

“Our findings confirm that, in historical populations, life expectancy was low because people were dying young. But as medical, social, and environmental improvements continued, life expectancy increased. More and more people are living much longer today. But the path to death in old age has not changed. “Our study shows that evolutionary biology ultimately determines everything, and so far, medical developments have been unable to overcome these biological limitations.”
