I grew up in sunny Australia - the skin cancer capital of the world. So I know that my environment will affect my health. But how much can things change between neighbourhoods?
A new health atlas shows the spread of 14 conditions, including cancers and heart disease, in communities across England and Wales.
It's cool to explore and look at patterns. But the atlas can't show how factors such as fitness and lifestyle affect your health. I wonder how people will use this information?
