I'm one of those who normally sleep only 6.5 hours per day. As stupid as it sounds, I need someone telling me that I should sleep more. After reading an article like this I'll start sleeping 8 hours a day, and if the article is right, I'll feel better and more productive. So the article is useful for me, hence the upvote. I do agree about 3) though.
