“Herkou"
"Herkou" is a word in Afrikaans that translates directly as "re-chew".
Cattle "herkou" when they bring up cud and chew it again. The technical term is to ruminate, which is something a ruminant does.
Humans also "herkou".
Humans are not natural ruminants.
When we re-chew it is worth considering whether we are making progress or whether we just need to let this cud go.
