actually, Voxel is dead-on when he says that it is "naive" to assume that other professions don't have the same stress levels as physicians....
contrary to what you think, most lawyers don't just make a living suing McDonald's for hot coffee, and those in finance aren't just playing some big game with numbers that go up and down...
maybe you haven't heard of "judges" or "district attorneys"? or maybe you're not aware that pension funds and insurance companies, who provide money for people to retire upon and make it possible for people to receive health services, invest heavily in the stock market to provide for us all. Realize that there are individuals who ultimately make the "go"-"no-go" investment decisions, that ultimately affect us all.
of course, I only use these examples cause you brought up law and finance. what about police officers, firefighters, nurses, military commanders, air trafffice controllers, etc? these all have the "high-stress" of saving lives that you claim is only inherent to physicians and pilots.
it's a multi-faceted and complex society we live in my friend, in which many people take on positions of high responsibility that impact us all. it's time you get off your "I'm a doctor" high-horse and realize that.
