Have you ever wondered how old humans can live?

Scientists believe they've confirmed the maximum age people may expect to live to, according to a study published this week in the journal Nature Communications, based on an iPhone app and much medical data from volunteers in the U.K. and the U.S.

The upper limit of human mortality, according to researchers, is 150 years.

Researchers from Gero analyzed medical data from participants in cooperation with Roswell Park Comprehensive Cancer Center in New York.

Researchers used artificial intelligence to evaluate health- and fitness-related data and discovered that two factors influence human life span the most: biological age (which is linked to stress, lifestyle and chronic diseases) and resilience (how quickly the person returns to normal after responding to a stressor).

According to a news release, based on this data and related trends, researchers concluded that at roughly 120 to 150 years old, the human body exhibits "complete loss" of resilience, resulting in an incapacity to recover.

"As we age, more and more time is required to recover after a perturbation and, on average, we spend less and less time close to the optimal physiological state," study author Timothy V. Pyrkov said.

According to Andrei Gudkov, the vice president of the Roswell Park Comprehensive Cancer Centre, the study marks a "conceptual breakthrough...It explains why even the most effective prevention and treatment of age-related diseases could only improve the average, but not the maximal, life span, unless true antiaging therapies have been developed," The Independent quoted him as saying.

Jeanne Calment, a 122-year-old Frenchwoman, was the world's oldest person. She died in 1997. Jiroemon Kimura of Japan, who lived for 116 years until dying in 2013, was the second oldest.

Despite the new calculations there is no evidence any human has lived past 130 years.
