1) It started long before millennials. Gang showers pretty much disappeared in anything built after 1990. 2) I hear the military has mostly gone private showers too. Thats how pervasive this trend it. 3) I remember school teacher friends complaining how smelly their students were. They just would not shower after gym class and still dont. These days many schools are so informal that kids just wear athletic clothes all day. 4) Other than sociological phenomena, I dont really care.
