Why didn't I think of this before? Yesterday, while munching on a carrot, some of the carrot got stuck in my throat. Realizing that this never happens when I eat vegetables with butter, mayonnaise or salad dressing, I had the bright idea to put a pat of butter in my mouth and let nature take its course. It greased my throat and the carrot went down. As a preventive measure, I find taking a magnesium supplement helps. (I take 200 mg of magnesium glycinate daily.) Magnesium is needed for proper involuntary muscle function: it's a standard cure for constipation, and doctors give it to patients having a heart attack.
