Cure for an itchy back

When I worked for the telephone company before I was married. I drew blueprints for the engineers telling them where to put telephone poles. The engineers would draw small drawings with instructions and I made them big and blueprints. Some of my fellow workers had good advice. One winter I was having trouble with an itchy back. Very uncomfortable and un lady like. One of my fellow workers told me there was a doctor in the building that could tell me what to do. I made an appointment. He took one look at it and said I had a dirty back that is why it itched, I needed to buy a back brush. At our house you took showers in the summer but in the winter you were back to the tub. I brought a backbrush and was cured.
