Cows have an excuse for it.
Rumination, that is.
Although it’s popularly said that cattle have more than one stomach, the truth is that they do have just the one, albeit with four compartments.
Their digestive process is something we won’t go into because it may well be your breakfast-time.
Suffice it to say, though, that a cow is an example of a ruminant, and the word ruminant comes from the Latin ruminare, which means to ‘chew over again’.
You, on the other hand, have a different kind of stomach.
Basically food goes down the hatch just the once.
Humans don’t ‘chew the cud’.
But we do sometimes ruminate in the other sense of the word.
The kind the dictionary calls ‘negative cyclic thinking; persistent and recurrent worrying or brooding’.
Although it’s an easy trap to fall in to, rumination when your mood is low seldom does you good.
The kind of thinking which just goes round and round usually doesn’t get you anywhere.
But being conscious of it is a good first step.
So if you catch yourself ruminating, do your damnedest to send the notion packing.
Unless, of course, you’re a cow.
