I also agree, but I'm a physician (an internist => generalist). As I grow in my career, I'm finding that when I encounter a new disease or procedure or treatment and go to read about it I learn an order of magnitude faster than when I was in medical school or maybe even residency. I'm amazed by it.

My retention is a bit better too, even if I don't see that new thing again for a long time, but not nearly what I wish it was... At least now I'll remember having seen it and a general sense of the concept even if I have to re look up the specifics.
