Quick! Go grab your high school yearbook, take a look at your senior photo. Are you smiling? Why does that matter, you ask. Well, psychologists say that in that very moment, you may have been determining the fate of your future marriage.

Results from a new study have just been released and according to that survey, the wider the smile in your yearbook picture, the less likely you are to get divorced.

Those who didn’t smile at all were five times more likely to get divorced at some point in their lives compared to those who smiled the biggest.

Psychology Professor Matthew just released a book entitled “The Tell” that digs into the study and he has a couple of theories about this phenomenon.

One of his theories is that people who are naturally happy and smiling go on to have happier marriages. His second is that people who smiled widely when a photographer told them to are naturally more obedient, which tends to be a trait that can hold a marriage together.
