Ok you're correct, I over-generalized. But a large fraction of nurses i've met are very simple thinkers, with limited capacity of abstraction, and they overestimate their cognitive powers/knowledge. Some years back my dad got hurt pretty bad and had to stay in the hospital for weeks. I flew out to see him and had to deal with docs / nurses day in and day out. Now I hate them. Also, they might really be better where you're from.
