We, as practicing dentist, also learn from cadavers. However, we do not dissect them as such due to limited specimens.
Re- Importance of the title Dr. Not that great. If you go into a health science course, it should not be for the respect or title. It should be for passion. Be careful with your answer of "I like helping people". It's generic. Unfortunately, interviewers, like most people are judgmental, they will not believe you for a second.
Surgeons, with respect to title, get somewhat of a downgrade from Dr to Mr or Ms. Weird but true! However, I've had two surgeon lecturers, while one used Ms. the other kept the title of Dr.
Re-"Dr." House. He's nothing more than a concoction of studios. Watch it for pleasure, refine your physiology and antomical nomenclature and attempt diagnosis (even though most are either down right obvious, or, absurd). You should never "strive" for his personality. It is rude, careless and ignorant. Everyone, especially those in the health science field should be friendly and warm. NB: being a surgeon doesn't change this. If Nobel awardees can be funny, then surgeons should be funnier!
