Rumination Day
The core of this idea came from learning that one meaning of “ruminate” is “chew the cud” for ruminants, e.g. cows and goats, and that “ruminant” comes from their multi-chambered stomachs, including a large “rumen”. From there I had the idea of contrasting my own “rumination” in the form of a brain diagram. Happily enough, brains actually do have four main compartments, which worked very nicely for consistency purposes.
