Nurses care. They roll up their sleeves and do their work. Nurses are out there on the front line, listening to families, knocking on doors, working in schools, and being involved with the lives of people living in the community. Nurses are accustomed to "dirty business." A nurse changes dressings, carries bedpans, and deals with the most intimate parts of human life. Politics is dirty business, too. Politicians also roll up their sleeves and argue, debate, and proverbially "change bedpans" in order to change the social order. Politicians involve themselves in the lives of their constituents. They want to improve the day-to-day lives of people and do so by changing the laws and policies that govern. Firmly grounded in the concepts of primary health care, nurses change the lives of individuals, families, and communities by knowing what needs to be changed and then doing the "hands-on" business.
