The current rotation I am on is quite demanding, and I am regularly clocking up more than 60 hours per week.
Still, I am not over-tired and am learning quite a lot. Frankly, it would be hard not to learn.
In a few weeks I am hopefully going to be 2/5 of the way through my intern year.
In the Australian system, we enter a specialist training program after being an intern/resident for a year or more. This means we get to see a bit of areas that we have no interesting pursuing and theoretically get a well-rounded grounding as a doctor.
There are a lot of advantages to this and only a few disadvantages. One of those disadvantages is that I am now too tired to type any more because this rotation is sucking a lot of time and energy out of me (but this is okay), so this is all I'm going to write.
