Is your heart aging too fast?

Researchers have developed a revolutionary new way to find out the 'true age' of your heart using MRI. A new study shows how an MRI scan can reveal your heart's functional age -- and how unhealthy lifestyles can dramatically accelerate this figure. It is hoped that the findings could transform how heart disease is diagnosed -- offering a lifeline to millions by catching problems before they become deadly. The team say their cutting-edge technique is a 'game changer'.
