<P> The practice of blessing someone who sneezes dates as far back as at least AD 77, although it is far older than most specific explanations can account for . Some have offered an explanation suggesting that people once held the folk belief that a person's soul could be thrown from their body when they sneezed, that sneezing otherwise opened the body to invasion by the Devil or evil spirits, or that sneezing was the body's effort to force out an invading evil presence . In these cases, "God bless you" or "bless you" is used as a sort of shield against evil . The Irish Folk story "Master and Man" by Thomas Crofton Croker, collected by William Butler Yeats, describes this variation . Moreover, in the past some people may have thought that the heart stops beating during a sneeze, and that the phrase "God bless you" encourages the heart to continue beating . </P> <P> In some cultures, sneezing is seen as a sign of good fortune or God's beneficence . As such, alternative responses to sneezing are the French phrase à vos souhaits (meaning "to your wishes"), the German word Gesundheit (meaning "health") sometimes adopted by English speakers, the Irish word sláinte (meaning "good health"), the Spanish salud (also meaning "health") and the Hebrew laBri'ut (colloquial) or liVriut (classic) (both spelled: "לבריאות") (meaning "to health"). </P> <P> In Persian culture, sneezing sometimes is called "sabr = صبر," meaning "to wait or be patient ." And when trying to do something or go somewhere and suddenly sneezing, one should stop or sit for a few minutes and then restart . By this act the "bad thing" passes and one will be saved . </P> <P> In Greek culture, sneezing was widely recognized as a divine omen . In Book 17 of Homer's Odyssey, Penelope speaks to Eumaeus in private about the suitors feasting in the halls of the king's palace, and how surely Odysseus will return and kill them . Suddenly her son Telemachus sneezes and Penelope laughed . A sneeze meant the intercession of the gods to make her statement come true . It was a blessing from the gods, connecting the sneeze to the "God Bless You ." </P>
