What common medical tools, e.g., a microscope, didn't he use Why
2. How has John Snow's work affected our daily lives
1. Maps and statistics. He didn't use the common medical tools such as a microscope was because they didn’t exist during his time. Further, understanding of germs and bacteria was still developing, and so he had to innovate methods himself based on the theory he believed.
