The term depression shouldn't be thrown around as much as it is, but I guess they use the term "clinical depression" for the full psychiatric diagnosis?

Depression has a different definition in economics, meteorology, astronomy, regular language. Mania, not so much. Maybe that's why depression is more widely used. I have heard people who are not bipolar call themselves manic. It's pretty obvious that they are not. The word "maniac" comes from the same root as "mania".

What are nons? Is that a term to describe someone without a mental illness? I've never heard that before. I wouldn't want to be called a non.
