Cognitive epidemiology

Cognitive epidemiology is a new field of epidemiology that studies the relationship between intelligence and health, illness and mortality. For example, men with a higher IQ have been shown to have less risk of dying from coronary heart disease and increased life span.

Possible reasons for these findings

 * Higher IQ may mean more highly paid jobs and this would reflect the link between income and health.
 * It may mean that better self care and readily following health care advice may be an intelligent choice.
