Being married cuts your risk of having a heart attack and makes you more likely to survive cardiac arrest if it does happen - especially if you're the wife.
A new study reveals single and divorced people have the highest risk of fatal attacks at any age, with a greater chance of dying before getting to hospital.
The study is significant as most research suggests marriage may protect the health of men more than women.
Experts say the benefits come from a positive effect on lifestyle, with married couples having more money, better health habits and social support than singles.
