An interesting last paragraph, Mike. Whether it be true or not, it does
throw an element of realism into the equation. Realistic behaviour is
something so often lacking in archaeological interpretation, instead our
ideas and concepts become restricted by clinical analysis and dogma.
If it doesn't fit the recognised classification or stereotype it can't be
considered.
