Found on some random website...

"A remedy for leg cramps that is borrowed from the world of accupressure.....when your leg cramps up, squeeze your upper lip between your thumb and index finger, and hold for a minute or so. I don't know the physics or medical reason of how/why this works, but it does."

I've been told that the same action can stop a sneeze when you feel one on it's way. I'm very bored.
