　　 These days many people start their day by going into the bathroom towash. They turn on a faucet and hot water runs into the sink. They pickup a bar of soap and wash their hands and face. They take a towel to drythemselves. Then they put toothpaste on their toothbrush in order to brushtheir teeth. Not so long ago, however, many homes did not have bath-rooms at all. Soap was something that only rich families could afford, andpeople did not think it was necessary to brush their teeth.
