Three comments of a healthcare class instructor...

...who is (African) from (south-central Africa): 1) "This is hard, when I studied it as a nurse, I did not understand it, and I thought maybe it is because I am African, but no, it is hard." 2) (pointing to a lung strengthening device) "These you see here, but Africa is not well-resourced, when I worked in [name of her country], we used empty balloons, and instructed the patients to blow in them with all their might." 3) (on necessity of full patient care) "Remember, how you treat a patient is how you treat yourself, if you do not wash the patient's hair, it is because you do not wash your hair at home, look at you, are you like that!"
