"The twentieth century saw incredible gains in global life expectancy: in 1900, the average person lived to 32 years, a figure that had more than doubled by 2000. This trend seems to have stalled in the most developed parts of the world. In Europe, for instance, life expectancy increased by almost three years from 2000 to 2010, but grew half as much in the following decade, and that was before the COVID-19 pandemic prompted a global dip in longevity."
"Those harbouring hopes of humans finding new ways to improve lifespan can take solace in the fact that research in this area - through the relatively young interdisciplinary field of geroscience - is booming. By focusing on understanding the biological mechanisms underlying ageing, researchers are zeroing in on a number of treatments that hold the promise of slowing down the process, therefore reducing the risk of disease."
Global life expectancy increased dramatically during the twentieth century, rising from about 32 years in 1900 to more than double by 2000. Growth in life expectancy has slowed in the most developed regions, with Europe gaining almost three years between 2000 and 2010 but only about half that growth in the next decade, before the COVID-19 pandemic reduced longevity. Geroscience, a relatively young interdisciplinary field, is expanding rapidly. Researchers in geroscience focus on biological mechanisms of ageing and are identifying treatments that may slow ageing and lower disease risk. A central question is whether priorities should emphasize longer lifespan or longer healthspan.
