Howell shows how the healthcare industry was changed by technology when discussing pneumonia in the late 1800's. It wasn't their technology in the sense that they had new machines that could tell them if a patient had a disease or not; it was their systematic way of keeping records. They made diagnosing pneumonia a science by finding out common factors (white blood cells, leucocytes, etc.). Howell writes about how they did not actually count the patients white blood cells, but there were other common factors to determine this vital information for diagnosis. I find cases like this amusing because they are taking medicine and healthcare from a case by case basis and turning it into a methodical science. It went from a to-do list based on symptoms to a system in which the scientific method could actually be applied.
