So far I have decided in working in either medicine or technology, with the intention of helping people. As far as technology, I planned on majoring in chemical engineering and going to grad school for nanotechnology, and trying to use nanotech to help fight cancers/diseases etc. My other option was to go to med school and be a trauma surgeon. Although both choices are aimed to benefit society in one way or another, the latter is more theoretical in approach it would seem, because I may never really find a way to use nanoscience to help against diseases and such, but if I were to be a trauma surgeon, I would be directly helping people on a daily basis. I am torn between these two career choices, and was wondering if anyone could provide any insight between the two, including med/grad school. I know for a trauma surgeon I am looking at around 14 years of school, where as for an engineer it was more like 6 for my masters, and an additional few years for phd if I decide to go that far. Thanks for your help in advance.
