I suffer the ignominy of teaching at a Catholic school, where liturgical services include the exchange of a "handshake of peace." Good lord. If there is one thing I don't want to do, it's shake the hands of a bunch of people who have just been shaking each other's hands.
If you listen and look around for the fifteen minutes before this idiotic custom, you hear and see dozens of people coughing, sneezing, etc. This handshake of peace is a barbaric custom. It should be banished. I'm all in favor of the "elbow bump of peace." If this influenza becomes pandemic, the stupid Catholic church will be responsible for much of its spread.
