Study finds biological limit to human lifespan around 150 years

A new study suggests a biological limit to human lifespan, estimating it at around 120 to 150 years due to declining physiological resilience. Researchers analyzed blood cell and step counts, finding that the body's ability to recover from setbacks diminishes with age, regardless of health status. This intrinsic biological property indicates a fundamental limit to human longevity, aligning with the longest recorded human lifespan.
