A new study publishedin the journal npj Aging has sparked a wave of debate about the limits of human capabilities and their persistence with age.
Using mathematical modeling techniques, scientists have concluded that the theoretical maximum human lifespan could reach about 146 years, and in some scenarios it could even rise to 194 years.
However, the study's authors urge caution in interpreting these results, explaining that these figures are merely mathematical estimates resulting from a mathematical model, and not practical evidence that modern medicine or lifestyle changes can grant a person a lifespan approaching two centuries.
The official record for human longevity still belongs to the Frenchwoman Jeanne Calment, who died in 1997 at the age of 122, a figure that new projections still surpass by a considerable margin.
The new model is based on the analysis of somatic mutations, which are genetic changes that naturally accumulate in the body's cells throughout a person's life. According to the U.S. National Cancer Institute, these mutations occur after fertilization during cell division and under the influence of various environmental factors. While most do not cause direct harm, some may accelerate tissue aging and increase the risk of cancer and age-related diseases.
Instead of searching for a specific age at which the human "biological clock" stops, scientists attempted to determine the upper limit of lifespan under ideal biological conditions. Modeling showed that the rate of cellular damage accumulation plays a key role in determining lifespan, opening new avenues for understanding the mechanisms of aging. However, researchers emphasize that this hypothesis requires further experimental testing.
Unlike some personal experiments in the field of "biohacking," such as those conducted by entrepreneur Brian Johnson, this academic study does not offer special diets, supplements, or exercise programs that claim to be able to extend life to 146 years, but rather aims to understand the biological basis of aging.
Scientists confirm that there is currently no clinically proven intervention that can radically extend the natural limits of human lifespan.
Even if the theoretical lifespan of 194 years is not achieved, studying the mechanisms of aging may help in developing treatments that extend what is known as the "lifespan of health ," that is, the years a person lives with vitality, independence, and with the least amount of disease—a goal that goes beyond simply increasing the number of years of life.
Experts call for a distinction to be made between evidence-based scientific research and unproven personal experiences, stressing that the best known ways to maintain health are to follow a balanced diet, exercise regularly, get enough sleep, avoid smoking and alcohol, and undergo timely checkups and disease prevention.
