Yawn!

This is for real! A study from the University of Pisa took a look at 109 men and women from different countries and observed their yawning pattern.

What they found is that yawns are especially contagious when in the company of close family. They were less contagious around friends, and much more rare around strangers.

So, the closer the relationship is, the faster the yawns move between senders and catchers.

If you're out on a date, test the other person out, let out a big yawn. See if they yawn back. That could just be the worst piece of advice I've ever written.
