Since 2015 Public Health England (PHE) are encouraging people to take a simple three-minute online Heart Age Test.
It includes questions about factors known to have an effect on cardiovascular disease risk.
PHE has analysed 1.2 million test results so far.
The main finding is that 1 in 10 men aged 50 who've taken the test were found to have a heart age of at least 60, and around half of people didn't know their blood pressure.
