Q: You recommend niche worrying. What is it?

A: Niche worrying is a means of conveniently organizing one's paranoia. It's concentrating on a specific fear or phobia at an appropriate time, like focusing on getting Legionnaires' disease from inhaling steam containing Legionella pneumophila bacteria while taking a shower at the gym.
