What are you going to medical school for? I might want to go in my later years to pursue a career as a homeopathic doctor. Even if it takes me 8-10 years of my life just to be a doctor, I may do it.
I'm hopefully finishing undergrad in psychology and neuroscience within the next year and then going to grad school to finish my post-bach pre-med and do molecular neuroscience.
I want to work in research, ideally, helping cure people who suffer from depression, and anxiety, schizophrenia, etc.. but on a molecular level, rather than through general psychology.
