One of the worst parts of my job as a professor is grading. Mind-numbing and neck-stiffening, grading takes huge amounts of time. Reading the same essay question responses or lab reports and papers for dozens of students is so unpleasant that we almost have to tie ourselves to our chairs to get us to do it! And, of course, with stressed-out students beginning and completing those assignments by pulling all-nighters, the quality of some of that work makes the task all that much more stultifying.
