If ever a person needed to be a germophobe, it would be in the hospital. I've always joked that my mother would have made an excellent surgeon, because she washes her hands dozens of times a day under hot water for half a minute.
A sterile field could really benefit from people like this. I would hate to have someone who was lax about cleanliness and procedure in the operating room working on me.
I realize that many people think that the requirements for a sterile field are over the top, but they have to think about what is at stake. You can't be too careful about the environment in which you are about to cut someone open and expose them to whatever is lurking there.
