I'm amused, or slightly nauseated, when someone allows that they "think with their gut." (And I always think especially of our celebrated George W. Shrub.) Considering what, given a bit of time, fills the gut, anyone who "thinks with their gut" is admitting that they have "gut contents" for brains...
@Engineerbert. Lol - never seen that shorthand, but it has to read something along the lines of "too long - didn't read". Ah, the wish to be self-employed...
