old age
Let an agent explain old age as a life stage, relay definitions, biology, health and social aspects from gerontological sources with attribution, describe policy and cultural variation, and distinguish old age from ageing as a process, from specific diseases and from retirement as a status.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain old age as a life stage, relay definitions, biology, health and social aspects from gerontological sources with attribution, describe policy and cultural variation, and distinguish old age from ageing as a process, from specific diseases and from retirement as a status.
The final stage of the human life course, conventionally beginning around 60 to 65 years and sometimes divided into a third age of active retirement and a fourth age of frailty, including the oldest old aged 80 and over, characterised by biological senescence, changing social roles and rising risk of chronic disease and death, studied by gerontology and geriatrics and shaped by culture, policy and pension systems; old age is defined differently across societies and the concept of biological or body age is distinguished from chronological age.
What it is for: Not applicable; a life stage.
It can be explain definitions and stages; relay biology and health; describe social and policy aspects; distinguish related concepts.
Distinguishing features
Late life stage
Senescence
Changing roles
Culturally defined
What it looks like
Not a visible object; a stage of life.
Physical character
conventional threshold: 60-65 years - varies
people aged 65 and over worldwide: about 800 million - estimates, rising
life expectancy at 65: about 15-22 years - high-income countries
How it is recognised
Final stage of the human life course
Third and fourth age, oldest old aged 80 and over, biological body age
Ageing is the process; retirement is a status; specific diseases are separate
