Let's set the scene: I'm out with a friend for a postwork drink and toss my purse on the empty stool next to us. About 20 minutes later, the place fills up and I see a suited gentleman eying the seat. I pick up my bag, smile apologetically, and turn back to my friend. Easy enough?

That's what I thought, too, but then he sits down and makes some comment about my cute dimples. This wouldn't have been a bad pickup line . . . if I actually had dimples.

Formed by muscles that pull the skin inward at the edges of the mouth, these tiny dents are often complimented by doting parents but scowled at when they appear, years later, elsewhere on the body. Do you have any on your face?
