Intrinsic capacity assessment works—let's move on actions

Rising global life expectancy, exacerbated by declining fertility rates, is driving a complex demographic shift—population ageing—with ripple effects on health care, social welfare, economies, and intergenerational relationships around the world. In 2015, WHO published the World Report on Ageing and Health, defining healthy ageing as a process of developing and maintaining functional ability.1 Within this framework, the concept of intrinsic capacity was proposed to represent the biological construct that supports an individual's functional ability.
