Researchers at New York University's Medical Center found that your marital status does have an influence on your heart.
This study was the largest of it's kind and looked at 3.5 million people.
They found that those who tied the knot had a five percent lower a risk of developing cardiovascular heart disease.
Compare that with single people and widowers who had a three percent higher risk, and those who were divorced at a five percent higher risk.
And if you are younger -- the benefits could be even greater.
The study found that these numbers jumped for younger married people.
If you are under 50, they found, you had a 12 percent lower chance of heart disease.
The researchers say that one of the reasons that this may be true is that your spouse is there if you are in poor health -- to take you to doctors appointments and help keep you healthy.
