What's with the night shift working day jobs?
This stands out to me as the most unrealistic part of the show. You get off your 12 hour shift, and now have 12 hours to get home, get some sleep and eat a real meal before going to back into the proverbial Pitt for another 12 hours. Instead Abbot puts on a uniform to tag along on a raid and intubate under fire and the night shift charge nurse spends half the shift caring for the dying cancer patient. They're getting, what, four hours of sleep? If you're in your early twenties, then you can, to some extend, treat sleep as optional, and pull your weight after 3-4 hours of sleep. But Abbot and Lena are both at an age where your body is just not going to go along with this, not on the regular.
