Human longevity has increased significantly over the past half century, which has led some researchers to explore whether this is a trend that will continue. There are more 100 year olds alive now than at any other point in human history and a growing number of supercentenarians 110 years old or older, including 110-year-old Minnesota resident Marie Willan.
Dr. Jan Vijg, a researcher at the Albert Einstein College of Medicine in New York, analyzed longevity records from around the world, including reports from the International Database on Longevity and Human Mortality Database. He and his colleagues found a steady rise in the age of the oldest people who died between the 1960s and 1990s. However, beginning in the 1990s that oldest age did not change, according to Dr. Vijg.
In his recent conclusion published in the journal Nature, Dr. Vijg declares the maximum human life span has likely hit a ceiling of 115 years, although very rarely a person lives beyond that. The oldest person officially recognized died at 122 years old in 1997 in France.
