Also known as chewing our cud, both figuratively and literally speaking. It tastes about the same and smells foul, which is precisely what happens when we concentrate on shit we can’t change. Ruminants are animals that do this regularly-cows, sheep, goats, etc……however, they are a lot better at processing their diets than we are in this regard. Rumination is circular, and while in ruminants it serves a superb purpose, in us, it’s simply a waste of the only resource we can’t get back: time. Thanks for the article.
