Hello , What is the most lifestyle-friendly residency with minimal patient contact ? Is it Pathology , Radiology , Clinical Pathology ? I would like to explain my situation. I'm not living in the US , So my situation is not typical. I would like to choose a very lifestyle-friendly residency because I have other interests other than clinical medicine. I'm an avid reader. I spend most of my time reading books , programming & Solving problems in theoretical physics. I have been always interested in physics and mathematics. Not medical physics but High energy theoretical physics like string theory & Quantum field theory. Now , I have completed 7 years of medical school with high grades & I'm now 26 years old. But I don't have an undergraduate degree in physics or mathematics which are the subjects my real passion lies. Is it possible to do a clinical pathology residency and continue to do my hobbies as I have been doing before ? Or is it best to leave medicine & Try to apply for PhD Programs & Take the GRE test ?
