Folks would bring cots and blankets during Finals week while studying in the Engineering building at my university. Engineering students were not being coddled - you had to put in countless hours of study to make the grade.
Pushing 40, if I went back to college, and all the kids were taking cots to the engineering building to sleep on while somehow getting ready for a final, I'm sure I'd have nothing to do with it. I'd push the midnight oil if I could, then I'd go home, sleep snug in my bed, and be back bright eyed and bushy tailed at 5am to get started again.
But when I was 20, I'd be there with my cot, no question.
