Did you know that if you pop zits, pull nose hair, get a face piercing, etc. you could die?
There's an area on your face called the Triangle of Death(!!!) from the corners of your mouth, to the bridge of your nose. The blood vessels there lead straight to the brain, so if any bacteria gets into them, they head straight to the brain. Any open wound in that area could let bacteria in... Yeah...
Maybe that would convince my sisters never to get face piercings...
