Noticed something strange while staring at a bag of Ricola sore throat drops after another night of little or no sleep. There are 19 drops in a bag of Ricolas. Why 19? Why not bump it up to 20? Is it a Swiss thing? Anybody got an answer? Just curious. After all, I heartily endorse Ricola sore throat drops after a long night of hacking up part of one's lung, so they could put 17 or 23 drops in the bag for all I care.
