ZEUXIPPUS. A friend of ours then heard one alleging that to keep one’s hands always warm and never suffer them to be cold did not a little conduce to health; and, on the contrary, keeping the extreme parts of the body cold drives the heat inward, so that you are always in a fever or the fear of one. But those things which force the heat outwards do distribute and draw the matter to all parts, with advantage to our health. If in any work we employ our hands, we are able to keep in them that heat which is induced by their motion. But when we do not work with our hands, we should take all care to keep our extreme parts from cold.
