We humans often see ourselves as separate from the animal kingdom, you have animals and us. I personally think that Mother Nature came up with something different concept and I see a lot of similarities between humans and animals. One of them is regular washing and brushing, which many animals do in a kind of car wash. That is of course not a street with rotating brushes or a wax turn, but a place where certain animals help other animals to stay clean while they themselves immediately get a meal and so everyone benefits from it.
