The fundamental problem is that we have 2 classes, & that the 2nd is growing....You and me both.
1) What's traditionally called "normal"
2) Everything else.
If the label for #2 is to be an inventory of alternatives, then it will continually grow.

Naturally, I have a proposal....
#1 = "Norms" (for normal)
#2 = "Abs" (for abnormal)
So far, no one likes my idea (including me).
