An ol wives' tale or old wives' saws is a proverb, much like an urban legend, which is generally passed down by old wives to a younger generation. Such 'tales' usually consist of superstition, folklore or unverified claims with exaggerated and/or untrue details. It is so named for the alleged lack of sophistication of old wives. Today old wives' tales are still common among children in school playgrounds. Old wives' tales often concern pregnancy, puberty and nutrition.
