An analysis of the number and severity of health problems among the population of a certain community showed that elderly people who were born in the community and resided there all their lives had significantly worse health than elderly people who had moved there within the past five years.
Apparent Paradox
How come elderly people who are long-time residents are worse off, health-wise, than elderly people who are new residents?
Evaluate
We need a distinction between long-time residents and new residents, that is common sensically related to health.
