I think it’s important to consult the good lord Darwin and meditate on the genetic wisdom of whining.
An animal which is usually the target of predators will usually attempt to hide its injury as this may draw and encourage predation.
Animals which hunt, or herd gain benefit from communication. Setting off a call of pain or cry of help, warns the group of the threat to individual and group.
Discomfort is experienced subjectively as a need to communicate and a need for assistance. This is a vitally important trait. The noxious experience is for the benefit of the organism – so hopefully it will stop stepping on that nail.
Hopefully then you will agree it is my God-Given, Evolutionarily approved right to whine and if you don’t like that then….
don’t worry, you will like our socialized medicine.
