Looking younger, dying later: General practitioners' intuitive clinical impression predicts mortality.

In daily practice, general practitioners (GPs) have to assess the health status of their older patients.

The objective of this study was to analyse the characteristics associated with this estimate of apparent age and to determine if it is predictive of death in the next 3 years.
