Do you smile so much that people always think you are up to something, or are you someone who always has a stone look on their face?

If you fall under the second category, you might want to rethink your facial expressions.

Experts at Wayne State University in Michigan found that people who smile a lot, live seven years longer than those who don't!

Researchers studied photos of 230 baseball players from 1952. Of the 184 players who'd died since, those who smiled most lived to an average 79.9 years compared to 72.9 years for non-smilers.

Experts say being happy reduces the risk of heart disease.

Does this mean that we can loosen the reigns on are eating regimen? I guess we will just have to wait for the follow-up study to come out!
