I find checklists useful for an routine and well-defined task, mission-critical or not. Just saves me a lot of headache by making sure I don't forget things. Stress from, e.g., forgetting milk at the store isn't the same as stress from operating on the wrong body part; but it's still an annoyance and easily eliminated--so why not?
