Physical and cognitive functioning of people older than 90 years: a comparison of two Danish cohorts born 10 years apart.

ABSTRACT:

Background

A rapidly increasing proportion of people in high-income countries are surviving into their tenth decade. Concern is widespread that the basis for this development is the survival of frail and disabled elderly people into very old age.
