maybe do it just to see if you'd like it, but don't bother sticking to it if you ha te it. they just want you to invest in fields in which you hold an interest. btw research isn't limited to the bench. research could be sociological studies, a history thesis, clinical work, stuff outside of medicine, etc. be creative! every cookie cutter premed shleps in the lab, they want to see people who played an ample role in lab or one in other types of research.
