How is invigilation "soul destroying"? You just walk or stand around as students write exams. Grading exams is tedious, but invigilating them is a neutral experience.

I don't mind grading exams (though I think grading is somewhat futile - see my link elsewhere). Sometimes an examinee will come up with a new idea, but we don't need formal examinations to check that kind of thing out. And you can do it in a comfortable chair, while listening to Miles Davis, unlike invigilation.
