Nobody actually chooses to have heart disease, but many doctors believe that you can now choose not to. Medical research has turned up three rules for a healthy heart, and doctors are recommending them to people at risk. This programme will tell you whether you're at risk, and what to do about it, and you can compare yourself with five people from all over Britain, including a famous businessman and a London housewife. Narrator RICHARD LEECH Producer KARL SABBAGH
