A worried looking woman sees her doctor.

Strung out, she rattles off, “Doctor, take a look at me. When I woke up this morning, I saw myself in the mirror with my hair all wiry & frazzled up, my skin all wrinkled and pasty, and I had this corpse-like look on my face. What’s wrong with me, doctor?”

The doctor examines her for some time, then calmly said, “There ain’t nothing wrong with your eyesight.”
