Lace up your dancing shoes, because terpsichorean (dancing) activities are good for your physical and mental well-being. The National Heart, Blood, and Lung Institute has found that dancing reduces stress and tension, and also helps to prevent heart disease. “Terpsichorean” — which can be used as either an adjective or a noun — originated from the Greek word “terpsichore,” referring to “a love of music and dancing.” The Greek word comes from an ancient Greek muse of the same name.
