Human Lifespan Limit Found: It’s Not 150

The absolute limit of human lifespan is 125 years, said Albert Einstein College of Medicine scientists in their study published in the journal Nature. According to them, this indicates that it may not be possible to extend human lifespan beyond this age.

“Demographers as well as biologists have contended there is no reason to think that the ongoing increase in maximum lifespan will end soon,” points out the study’s senior author Jan Vijg. “But our data strongly suggest that it has already been attained and that this happened in the 1990s.”

The study involved investigating the Human Mortality Database, which has all the mortality and population data of over 40 countries. Since the 19th century, a person’s lifespan as well as aging have vastly improved due to improvements in health, environment and others.

The team also found that gains in survival peaked at 100 years, but then humans declined rapidly in the years after. This decline is the same for all, regardless of date of birth.

The Albert Einstein College of Medicine scientists concluded that the average maximum human lifespan is 115 years. They then determined that the absolute limit of human lifespan is 125 years, and the chance for anyone in the world to reach this age is 1 in 10,000. It is very unlikely for anyone to reach beyond this point.

Vijg concludes, “Further progress against infectious and chronic diseases may continue boosting average life expectancy, but not maximum lifespan. While it’s conceivable that therapeutic breakthroughs might extend human longevity beyond the limits we’ve calculated, such advances would need to overwhelm the many genetic variants that appear to collectively determine the human lifespan. Perhaps resources now being spent to increase lifespan should instead go to lengthening health span — the duration of old age spent in good health.”

The oldest person on record is  Jeanne Calment, a French woman who died in 1997 at the age of 122 years.
