For centuries, humans have hunted the dream of immortalityMedieval alchemists in search of the elixir of life to modern billionaires investing in the research on longevity. But how long can we really live?
A revolutionary study of Singaporean scientists delivered an answer – one that is as fascinating as it is sober. Despite medical breakthroughs and advances in biotechnology, our bodies seem to have a Hard expiration date. And it could be lower than what we hoped for.
Are we close to our biological limit?
Throughout history, humans have slowly but regularly increased their average lifetime. Better conditions of health, nutrition and life have helped people live longer than ever.
Take Calment by JeanneFor example. The French, who holds the record for the longest verified human life, lived in 122 years old. A few centuries ago, reaching 100 was considered almost mythical.
With the rapid progress of today in medicine, some experts have hypothesized that Future generations could regularly exceed 150 years. But according to this new study, biology could have other plans.
The science of aging: why we do not bounce back like us
The research team examined Thousands of blood samples Individuals in the United States and the United Kingdom. Their goal? To understand how our bodies manage Stress, disease and recovery Over time.
Their key discovery: as we age, our ability to recover Diseases and injuries decrease considerably. A young adult can shake a fever or muscle tension in a few days. But at 80 yearsEven minor diseases can take six weeks to heal. And by 90 or 100, the recovery process becomes even slower – sometimes impossible.
This progressive decline is called physiological resilienceAnd it turns out to be the ultimate determinant of our lifespan.
The 150 -year -old wall: why even the healthiest bodies fail
According to the main scientist of the study, Timothy Pyrkovaging is essentially a idle collapse body capacity to maintain stability. Finally, the body becomes so fragile that even the factors of minor stress – as a light infection – can trigger a total failure of the system.
Using advanced mathematical models, researchers estimated that the absolute limit of human life is somewhere between 120 and 150 years old. Beyond this threshold, even the healthiest individuals would lose any ability to recover from health problems, leading to an inevitable failure of the system.
And here is the real kicker: this limit seems inevitableEven for those who avoid major diseases such as cancer or heart disease. The study, published in a declaration by Liftsuggests that the loss of resilience itself dictates our maximum lifespan – not only the presence of a disease.
B The Dynamic Organization State indicator (DOSI) The average values (continuous line) and variance (shaded area) are traced in relation to age for all participants in the Nhanes study. The average line demonstrates almost linear growth after the age of 40.
C Dosi distributions adjusted to sex and age in the cohorts of Nhanes participants in different categories of morbidity compared to the average dosi in the cohorts of “non-rail” (1 or no diagnostics, CMI
Why haven’t we yet beat the disc?
If humans are able to live for 150 yearsWhy did we see anyone going beyond the 122-year record of Jeanne Calment?
One reason is that if medical science has extended Average life expectancyTHE maximum lifespan possible remained unchanged. We are better to prevent illness and delay death, but we have not found a way to extend the biological ceiling.
The study suggests that even if we cure cancer, heart disease and other chronic diseases, the drop in Resilience will always limit us. Essentially, the body reaches a point where it can no longer repair itself, no matter its health.
The future of longevity: can we push beyond 150?
The results may seem discouraging, but they could redefine the Future research on longevity. Instead of simply focusing on disease prevention, scientists can start to target the loss of resilience itself.
Fields like Biotechnology, regenerative medicine and cell reprogramming Could offer new ways to slow down the loss of resilience – pushing possible human life beyond the 150 -year barrier.
For the moment, however, the message is clear: no matter how much we optimize our diets, exercise routines and medical treatmentsThere is a limit higher than human life. But although we cannot live forever, we can use this knowledge to live healthier and more fulfilling lives as long as possible.
The quest for longevity is not over – she enters her next chapter.
