Good sense of camaraderie amongst medics. Learn practical stuff, not as my brother put studying economics "learning lots of obscure theories that don't actually work in the real world. There's no real limit to how much you can learn. You are in a very priveleged situation, sharing people's most intimate and personal moments and for some strange reason you are allowed to stand and be a part of it, even though you are just a student. You have those rare moments as students where other people take your opinion to mean something. Somebody might thank you one day, which is always nice.
