Recent research continues to challenge the idea of a fixed biological limit to human lifespan, suggesting that indefinite longevity may be possible. Several studies and initiatives in 2025 are exploring the factors influencing how long and how well people live.
Ongoing Research and Trends
The Human Mortality Database (HMD) project continues to be a leading resource for researchers studying mortality and longevity. A symposium dedicated to investigating the drivers and obstacles to longevity progress is scheduled for October 9-10, 2025, in Aubervilliers, France.
The University of Zurich has established a Healthy Longevity Center (HLC) to research and promote the maintenance of functional ability and quality of life in older age. The HLC is focused on understanding the complexities of healthy aging and translating research into practical applications.
Life Expectancy Estimates
While some studies suggest a potential limit to human lifespan, with one study estimating it to be between 120 and 150 years, average life expectancy continues to rise. In the US, life expectancy is projected to reach around 79.4 years in 2025. Global life expectancy for 2025 is estimated at 73.49 years.
These figures reflect ongoing improvements in healthcare, living conditions, and public health initiatives. However, disparities exist, and factors like socioeconomic status and lifestyle choices can significantly impact individual life expectancy.
