"Breathing is boring."

[bugeyedmonster.livejournal.com]

Remember that line "Uh. Breathing. Breathing's boring." from the BBC Sherlock? Well are there any fics where Sherlock regrets that line? Like maybe he has broken ribs? Or a collasped lung with a drip line sticking out of his chest. (Which would make breathing REALLY uncomfortable.)

Any such fics around?
