The human neck
Images showing structures. A couple of brave women on casebook volunteered their neck measurements and these were averaged to get the size of the neck close to a real size. This is because actual measurements are lacking. It assumes these brave women are not no neck having professional wrestler types, or Olive Oyle like pencil neckers. The search for suitable images was several hours long and let me assure you, you find some disturbed people when you search for head and neck images.
We are all born cute as a button and dumb as rocks. We grow out of cute fast!
