I see what you are saying but I think you are ahead of ne there, Richard. When one has been addicted to something like smoking all one's life it is very difficult to give up the habit all at once. Likewise, once one sees the "light" it is very difficult to give up darkness. One has to force oneself to think of the world turning around rather than the sun rising in the east and going down in the west. Frank
