I find it quite galling that most "official" advice on the subject of sleep quality boils down to "simply get more sleep." This is a distinctly "let them eat cake" attitude - not at all unusual, however, coming from our medical establishment. I would like to thank the submitter, the author of the article, and the builders of the featured gadgets for creating something which might actually be of use to those who haven't the wealth to buy back their time, and must fight the effects of sleep deprivation without having the option of lying in bed to their heart's content.
