Something as simple as a yawn could tell you if someone really loves you or not. We've always heard that yawning was contagious, but apparently is even more contagious between people who love each other.

According to a study by Italian researchers if you yawn and your partner yawns as well, they love you.

So if you yawn in front of your parents, your grandma, your siblings, and hopefully your significant other, then they "should" yawn back.

And according to the study, the quicker they yawn back, the tighter the relationship.

However, the researchers say that the study isn't exactly 100% accurate.  So, if you yawn and your significant other doesn't immediately yawn back, it might not mean it's time to dump them, it's just one failed test, but it might mean you want to keep your eyes open for other failed tests.
