No, my permissive view of the organic processes of the human body certainly does not win any popularity prize, but it is probably worth some consideration in relation to the constrictions that are discussed more on the mental level. In my upbringing I grew up to such an extent that these things were not offensive. My parents also always left the door to the toilet open. Nothing was thought about.
The quotation? It makes something sound, doesn't it? Of course, man can build all kinds of things. But still he is unhappy, isn't he? You can't understand that saying through the front door, I think. It's more a feeling that expresses itself through it, that gets to the point without really making the point :)

Just curious.
