Being married has been linked to better rates of survival but it's not all doom and gloom if you are single.

It appears that having someone special in your life is what's important, rather than simply getting hitched, and that person could be a friend, family member or anyone else who gives you the drive to look after yourself. 

To me, the most important thing to note from this article is that the die is not always cast irrespective of what we do - how we live our lives and look after ourselves has a huge impact on our health.
