However being a ignoramus is not necessarily a devastating state to be in because sometimes ignorance is curable; but more recently it became clear that you are also incapable of learning, or at least learn at such a slow rate it is unmeasurable by me. And unfortunately at the present day medical science has no cure for stupid. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
