The Ecological approach will be the most useful approach to use when learning medical anthropology because it helps show how diseases can move throughout populations over time. With the knowledge of how the diseases spreads through a population, you can make decisions on how to stop the spread and help save more lives or help the population to heal from the disease. You always hear on the news about how this disease, or this illness has shown up in a certain population or state, and then the government figures out a plan to use that will help to stop the spread of the disease so that less people become infected by it. The ecological approach can also help to prevent diseases from starting in the first place by limiting its contact with humans.
Disease and illness while similar, are separate things; in my opinion disease is a form of illness. I think of it in the way that illness covers a large field of medical issues, which includes diseases. What made me think this way is that people do not ask you if you feel diseased, they ask if you feel ill.
The culture that Miner described is the American culture, it was made pretty obvious when geographically he said it was between Canada and Mexico. Then how he described the rituals and social factors seemed to sound more and more familiar as he progressed to which it sounded like how like the American culture.
The ritual of teeth gouging and cleaning show how the mouth in the Nacirema society views the mouth as a connection to healthiness and if you have decay in you mouth that you are ill. Then the ritual of mutilating your body to try to conform to a less humanistic form of being shows that how your body looks is a direct correlation to your health as a person; if you look abnormal from the normal then you are thought to be less healthy.
