Are you worried your heart is much older than you are and that you're on the verge of having a heart attack?
Well a test can estimate the age of your ticker, as well as revealing how long you can expect to live without having a heart attack or a stroke.
But a new update to the 16-question tool offers advice and interventions to help lower the vital organ's age and keep you alive for longer.
Produced by NHS Choices and the British Heart Foundation, the Heart Age Tool asks for information about your age, gender, height and weight.
It also seeks to know where you live, whether you're an active smoker and your ethnicity - all factors that impact the risk of having a heart attack or stroke.
