Cancer and its damages

I always wonder. Why would some medical students want to change their courses. I know they never failed in their pro exam, but they decided to have a change of heart. Unless they really failed the exams, that I understand lah. What I didn't understand was for those brilliant people who suddenly stopped being a medical student in the middle of studying (let's say fourth/third year), changing to other courses.

I still did not get why my seniors in USMKK, left medicine and went to dietetics, biomedicine. (usmkk-ians, you know who i meant). I never asked them why. Cuz I don't think they will be able to answer my curiosity... Better not ask right?


And this is a story of my friend. Let's call him Luffy.
