A woman rushed to see her doctor, Dr. Rosenberg, looking very much worried and all strung out. She rattled off, "Dr. Rosenberg, take a look at me. When I woke up this morning, I looked at myself in the mirror and saw my hair all wiry and frazzled up, my skin was all wrinkled and pasty, my eyes were blood-shot and bugging out, and I had this lifeless look on my face! What's wrong with me, Doctor?"
Dr. Rosenberg looked her over for a couple of minutes, then calmly said, "Well, I can tell you that there's nothing wrong with your eyesight."
