She is never sick. No colds, no stomach aches, no rotten teeth, not even a headache. For years she'd lived without insurance, but even after she was forced into buying a policy by the pervasive care of her employer, she never went to a single doctor.

Which she did, brushing her teeth three times a day or after every meal. But also she was a witch and knew how to fly.
