Page 6: Not even allowed to sleep? Everything else is extreme but at least not completely unreasonable; not so with that stipulation. Humans need sleep not just for biological processes, but psychological and mental. It's utterly absurd to make someone study without sleep! Sleep allows the brain to process and retain information better, a student will be far more effective at not only learning but remembering if they get sleep. This is completely counterproductive to good studying practices.

...not sure why I decided to be that verbose in that paragraph, lol
