Increased human longevity is largely driven by medical advances that enable survival with chronic disease, rather than by a biological slowing of the aging process itself. This distinction challenges conventional frameworks used to study aging and health outcomes. The authors argue that definitions of aging, health, and care need to be revised to accurately reflect the growing complexity of later life, where more individuals age in the presence of multiple conditions.
Why it matters
As populations age with greater medical complexity, health systems, researchers, and policymakers must adopt updated frameworks to accurately assess aging success and allocate care resources. Conflating longevity with healthy aging risks misguiding both scientific research and public health strategies.

A common misconception is that increasing longevity reflects slower aging. Instead, most longevity gain comes from medical advances that allow survival with disease, rather than changes to the biology of aging itself, challenging how we study aging and health.
Modern medicine has transformed not only how long we live, but also how we age, with more people surviving to old age with chronic disease. This Perspective examines how aging, health, and care should be redefined to reflect these increasingly complex later lives.
