Even though life expectancy has been steadily increasing over the past century, that trend likely can't go on forever.
The maximum "ceiling" for human lifespans is 115.7 years for women and 114.1 years for men, according to new research from statisticians at Tilburg and Rotterdam's Erasmus universities.
"On average, people live longer, but the very oldest among us have not gotten older over the last thirty years," Profesor John Einmahl told the Agence France-Presse. "There is certainly some kind of a wall here."
Einmahl said occasionally people do surpass that wall, noting the person with the longest confirmed lifespan, Frenchwoman Jeanne Calment. She died in 1997 at 122 years and 164 days old.
A similar American study last year also concluded 115 years as the average maximum human lifespan.
