A landmark study in Nature Communications identifies 150 years as the absolute limit of human life. Beyond this threshold, the body's resilience fails, making recovery from illness or injury impossible.
Scientific advances continue extending our lifespans, yet a hard ceiling exists at 150 years, per research published May 25 in Nature Communications. The findings reveal that, after a certain age, the human body loses its capacity to rebound from life's stresses.
This isn't the first modeling-based estimate. In 2016, geneticist Jan Vijg from Albert Einstein College of Medicine pegged the limit at 125 years. Others in 2018 claimed no upper bound exists.
Researchers from Singapore's Gero biotech firm, New York's Roswell Park Comprehensive Cancer Center, and Moscow's Kurchatov Institute analyzed anonymized blood test data from 500,000 individuals across the US, UK, and Russia.
They zeroed in on key aging biomarkers: the ratio of two white blood cell types and red blood cell size variability.
Using these, they developed a "dynamic organism state indicator" (DOSI) via computer modeling to gauge each person's recovery time from stressors like disease or injury.
Mathematical projections show resilience plummeting between 120 and 150 years, leading to incomplete recoveries and inevitable decline. Exceeding 150 years appears unattainable with current biology.
The team notes that boosting resilience in the elderly might require mechanical organs or cellular reprogramming—breakthroughs still on the horizon.
