Hmmm, I heard when I was a young girl, that every time you sneeze, your heart literally skips a beat. And back in the day before we actually understood exactly how the human body works(as if we have some full concept of this now?!), we used to bless our neighbor when they sneezed, in case that one skipped heartbeat caused one's death.

I know these are probably cultural differences, but I have to admit, I've never heard that one before. Interesting...very interesting!(in the words of Sir Isac Newton) I think it was him...right?
