How was your dad's health BTW? When I was little my mother used to give us a daily spoonful of Scott's Emulsion (which was mild tasting) during "cold season" and I disliked it but she usually gave me something to chase the taste away with. Some of my friends had it too and one even liked it and went for seconds!!!

Years later, when I was 18, I joined a gym and was found 10 lbs. underweight (what an irony!) and one of the supplements recommended for gaining weight "back then" was a cod liver oil that might have come from Germany (called Kepler's Emulsion). I very eagerly went to the drugstore and bought a bottle ignoring my mother's warning that it was thick and fishy tasting. Well, I gagged on it so bad I didn't want to hear about CLO for many years afterwards!
