To treat population instead of individuals. Just joking.
I choose public health because I will like to work with nonprofit organization help third world country, or here in State low income communities. Love Public health, but the last 2 years want to pursue medicine. I didn?t use MPH as a stepping stone; however, with public health experience I believe I will be a better doctor. For instance for preventive medicine you need MPH or some kind of public health course and training. Not all of us get MPH for the same reason some use it so they can get in medical, dental, pharmacy so on school.
