Kissing isn't only fun to do, but is also very beneficial to your health. We break down the science behind the kiss and the health benefits of making out.

After I was divorced and middle-aged and back in the dating pool, I unfortunately had to kiss a few more frogs. One I recall was a tongue-darter -- very disconcerting and unromantic. And another one was worse, he had bad breath and tasted like a dried-out steak every time I kissed him. Beef is okay to eat, but NEVER to kiss.
