Affected

They [the SS doctors] did their work just as someone who goes to an office goes about his work. They were gentlemen who came and went, who supervised and were relaxed, sometimes smiling, sometimes joking, but never unhappy. They were witty if they felt like it. Personally I did not get the impression that they were much affected by what was going on--nor shocked. It went on for years. It was not just one day.
