While the exact length of a human lifespan remains uncertain, scientists have attempted to define the ultimate age limit for humans. These findings might not sit well with biohacker Bryan Johnson, known for his innovative health practices that seemingly ‘reverse’ his biological age.
The upper age limits were proposed by statisticians from Tilburg and Erasmus universities in Rotterdam, who conducted a study examining the ages at death of 75,000 individuals. Their objective was to ascertain the potential maximum age a person could reach if they maintained good health and avoided fatal illnesses or accidents.
The study analyzed data spanning three decades up to 2017. It revealed that human lifespans tend to plateau in their nineties.
Despite this, many people have celebrated their centennial birthdays, proving that life can extend beyond the nineties.
The researchers concluded that 115 years is likely the maximum lifespan for humans. Women appear to have a slight edge over men in terms of longevity, with a maximum lifespan of 115.7 years, compared to men’s estimated limit of 114.1 years.
Professor John Einmahl, one of the study’s authors, explained the findings in an AFP interview: “On average, people live longer, but the very oldest among us have not gotten older over the last thirty years. There is certainly some kind of a wall here. Of course the average life expectancy has increased. Nevertheless, the maximum ceiling itself hasn’t changed.”
Although the research suggests a limit of 115 years, Einmahl acknowledged there are exceptional cases of individuals exceeding these age predictions. For instance, Jiroemon Kimura from Japan, verified by Guinness World Records, reached the age of 116. Similarly, French nun Sister André lived until 118, passing away early last year.
In September 2024, Guinness World Records recognized Tomiko Itooka from Japan as the current oldest living person. Born in May 1908, Itooka has surpassed 116 years of age and was honored with her official GWR certificate on Respect for the Aged Day, a Japanese public holiday that celebrates the nation’s senior citizens.
