[Hearing of a shinigami with a lung impairment immediately reminds her of Ukitake-taichou -- though he fortunately isn't afflicted with heart problems on top of that.]

Illness is not common among shinigami, in my world at least. I know of a similar case in my home, but have been unable to cure it myself. [She considers it a great failing of hers, that with all her skill and knowledge and ability, she isn't able to help Ukitake-taichou live free of his lung condition.]
