Immortality and the fountain of youth have been a source of fascination for generations, but a new study now states that this is likely to remain a myth as aging cannot be stopped due to biological constraints. The study pauses ongoing research to find genetic traits that can be used to reverse aging.
The Study published in the journal Nature Communications tries to investigate in which area a slowing down of aging is possible and whether there are biological restrictions that prevent this. While the new study could represent a boost to longevity research, drug companies are investing billions of dollars in developing ways to extend life through genetic intervention or the use of artificial technology.
The study, carried out by a collaboration of scientists from around the world, tested the “invariant rate of aging” hypothesis, which states that the human species has a fixed rate of aging after reaching adulthood.
Previous research in this area has attempted to analyze the longest lifespan of a human system.
Led by Fernando Colchero, Associate Professor in the Faculty of Mathematics and Computer Science at the University of Southern Denmark, the researchers analyzed the relationship between life expectancy and life-span equality, which measures the number of deaths in old age.

The researchers found that more people lived much longer because of lower mortality at a younger age, rather than slowing death down. They compared the birth and death dates of humans and non-human primates to find a general pattern. Longevity has increased as health and living conditions have improved over the years.
“Human death is inevitable. No matter how many vitamins we take, how healthy our environment is or how much we exercise, we will eventually age and die, “Colchero said in a statement, adding that life expectancy has increased dramatically and is still growing in many parts of the world World.
While the new study could boost longevity research, drug companies are investing billions of dollars in developing ways to extend life through genetic intervention.
The researchers also found that this pattern is similar in both humans and non-human species when analyzing records from primates including chimpanzees and baboons.

Previous research in the field had tried to analyze the longest life a human system can live. Researchers at Singapore-based biotech company Gero pointed to an underlying “aging step” that defines the lifespan between 120 and 150 years. The researchers looked at changes in blood cell counts and the daily number of steps people took. They examined health data from large groups from the US, UK, and Russia.
They found that with age, the factors beyond disease caused a predictable and gradual decrease in the body’s ability to return blood cells. While resilience decreases sharply from the mid-30s to mid-40s, the body loses all of its resilience between the ages of 120 and 150.
