Mountain dwellers have "better hearts"

People who live in mountainous areas have better heart health than those living in lowland areas, researchers suggest. As the BBC http://www.bbc.co.uk reports, a team from the University of Athens http://www.uoa.gr spent 15 years monitoring 1,150 Greek people. The Journal of Epidemiology and Community Health found fewer deaths in total, and particularly from heart disease, among those in the highlands. However, British experts have warned that high altitudes could be dangerous for people who already have heart disease.
