German for “great health and fitness.” Similar to the English phrase “Bless you,” it really is conventionally said to someone that has just sneezed. This reflects the superstition that a sneeze could potentially cause the soul to fly from the human body; stating the phrase helps prevent this from happening. https://buzzgram.de/alles-was-sie-uber-die-ernahrung-und-gesundheit-ihrer-katze-wissen-mussen/
