To be a doctor is as hands-on as you can be unless you speak of radiology, but that too is fascinating. You spend four years of your life doing hands-on work during the residency (rote learning?). There is an infinite amount of learning in medicine! Even after so many years of research, we do not understand the human body completely. I don't know what is you mean by boring; as a layperson, everything will seem boring unless you put in the effort to learn more about a field. But still, liver transplant, heart transplant, lung transplant, surgeries, anesthesia, diagnosing unknown diseases are not interesting? (flexibility? there are so many fields) I suggest you visit a Level 1 Trauma center close to your home and see what goes on in there. Reality is more brutal than TV in this case.

It may be boring to you, and that is ok, but it does not negate the fact that it is a challenging field and demands immense hard work to be one.
