What is the origin of saying "bless you" when someone sneezes?
Interesting. Is there any other superstition related to sneezing that you're aware of?
Yes, in some cultures, people believe that if you sneeze once, it means that someone is talking about you behind your back. If you sneeze twice, it means that someone is in love with you. And if you sneeze three times, it means that you are about to catch a cold.
