Bigger Smile, Better Marriage?

Were you voted "Nicest Smile" in your high school yearbook? If so, there's a good chance you'll have a successful marriage.

The correlation may seem arbitrary, but researchers have actually found a link between how big you smiled in pictures during your youth and whether or not you'll stay married.

Part of the DePauw University study in question involved rating people's smile intensity in their college portraits on a scale of 1 to 10. (The scoring was based on the apparent use of muscles that pull up the mouth and those that create wrinkles around the eyes.)

Not a single person who ranked in the top 10% of intensity had ever been divorced; however, a quarter of those in the bottom 10%, who had essentially frowned in their pictures, had been divorced at least once.

Another area of the study involved viewing childhood photos of people over 65, and once again ranking their smile intensity. This time, 11% of the big smilers had seen a marriage end, but almost three times as many non-smilers had been divorced.

The theories behind this connection range from the idea that big smilers attract other positive people into their lives, to the notion that those who do what a photographer tells them may be more obedient in a relationship.
