Some statisticians believe that the method called extreme value theory (EVT) is a powerful analytical tool  The curves generated by traditional statistical methods to analyze empirical data on human longevity predict that some humans would live beyond 130 years  According to the curves EVT generates, however, the limit on human life spans is probably between 113 and 124 years
To date, no one has lived beyond the upper limits indicated by EVT analysis
EVT fits the data about the highest observed human life spans more closely than do traditional statistical methods.
