The 10 second Rule does not relate the time food can be on the floor before it's deemed contaminated...it's a rule developed by my now wife...It only applies to me and it goes like this "think about what's going to come out of your mouth for 10 seconds before you decide to let it go, if you still think it's appropriate go ahead if not hold your tongue." I try and apply this to my photo stream too. @*#&@(#!... oops...forgot to count to 10.
