As I've gotten more experienced, I've found it hard to work with people who don't optimize for safety and efficency...not because I'm a worrywart, but because experience had shown that fucking up (royally) is much less likely caused by lack of skill, industriousness, or moral character, than by unforeseen weaknesses, stress, and cascading errors. Virtually every ER surgeon has spent more energy and time into their work than I have in mine, and every day they deal with life and death, and yet failing to wash their hands is not a rare occurrence...why should I think I'm any more foolproof?
