I could care less, well I COULDN'T care less...
Supposedly your heart stops when you sneeze. I do find it awkward to say as well though.People tell me that I'm rude for not saying "bless you" when someone sneezes. To me it's no different than coughing, sniffling, blowing your nose, or whatever other thing you do. Am I supposed to bless you for that too? Nope, just sneezing.
