Judy another approach that may work is comparing a feed at the breast to a "proper" meal....ie: appetizer, soup, salad, meat and the cheese or something of that density as desert...I understand that in the uk and some of the continent they serve cheese after the meal. this is the heavy caloric and filling part of themeal...a feed at the breast is the same concept...it starts light and works its way to the heavier. I am sure that much of your population does not have cheese after the meal and so am not sure what analogy is appropriate...please let me know. patricia
