We really are. If you look at any other animal, they clean themselves at will. The cat will give itself a lovely tongue bath and will willingly give other fellow cats one as well. Dogs will wash their paws for hours on end.
But, we humans...think. We decide whether we want to take a shower at all and when it will happen. There are people who do not bathe for one reason or another: religious, personal, etc. I leave out the sick because they physically or mentally cannot wash themselves. It is not their fault but the physically and mentally capable can wash themselves and sometimes do not. That perplexes me.
Other animals have the instinct to clean..how come we always do not? Is it because we think? Interesting..I should read up on this.
