Analyzing data from 1,100 super-long-livers (people over 110 years old) from 13 different countries, as well as information on all people over 105 living in Italy between 2009 and 2015, the study authors found that although the risk of death increases with age, it plateaus at age 105-110. From that time on, the risk is consistently 50/50 -- it's like flipping a coin every year.
If we extrapolate the results of this study, it turns out that, in theory, there are no limits to human life expectancy.
However, even if a person could live to 130 years of age or even longer, the chances of that happening are extremely slim. Few people even make it to age 110. But let's assume that you do succeed. After that, the odds of celebrating your 130th birthday are "about one in a million - not impossible, but very unlikely," notes Anthony Davison, one of the study's co-authors.
Although we will probably see more people reach 110 in the next century, the chance of someone crossing the 130 mark after that remains one in a million. At the moment, the oldest person in the world is Kane Tanaka, a super-loner from Japan, who is "only" 118 years old, and in 2033 she may celebrate her 130th birthday.
At the moment the record of human longevity belongs to a Frenchwoman Jeanne Calman, who died in 1997 at the age of 122 years. Her true age has been the subject of controversy because of concerns about possible fraud, but in 2019, several experts said that analysis of the evidence confirmed her age.
