Just discovered something I didn't know about burrows. If a dwarf is assigned to a burrow that doesn't include a hospital, other dwarves (even those who are allowed to go to the hospital) won't carry him to a hospital.
I'm doing a science fort, testing falling damage. My first test group was assigned to a nice tidy burrow to keep them from forming relationships with the staff. When I dropped them 5 levels, I expected a bunch of other dwarves to rush in ans haul the survivors to my hospital. And indeed, a dwarf immediately rushed into the test chamber, went next to one of the test subjects, and just stopped. So I checked to see what he was doing. Cleaning. Great, 9 dying dwarves on the floor, and this guy stops to wipe up a pool of blood. Then I added the hospital to the test group 1 burrow, and suddenly a bunch of dwarves rush to haul away the wounded.
BTW, dropping 5 levels onto schist resulted in 1 smashed head fatality, 9 unconscious from pain, ans 1 still conscious and still functional. While the rest are getting hauled to the hospital, he's headed back to his waiting area to plant some seeds. Just a couple of bruised legs and a nose that's mangled beyond recognition. His thought at this time is "I feel so good!"
Ahhh, this might explain it: "She feels euphoric due to inebriation."
