I want to become a neurosurgeon. i was wondering how many hours do they work?

Neurosurgeon: Average work week in hours is 80 to 90 hours and it can be even more.

Depends : It depends on many factors. Having said that, neurosurgeons commonly work far more hours than most physicians. I typically see my hospitalized patients 7 days a week. I am on call every third day and average 70-80 hours a week. It is not uncommon to work much more than that if emergencies require it.
