Great article. I especially like the interpretation of the statistics by the author, which is, well, hardly any interpretation at all: "One 2014 study of more than 3,000 people in Finland found that the amount of sleep that correlated with the fewest sick days was 7.63 hours a night for women and 7.76 hours for men. So either that is the amount of sleep that keeps people well, or that’s the amount that makes them least likely to lie about being sick when they want to skip work. Or maybe people who were already sick with some chronic condition were sleeping more than that—or less—as a result of their illness. Statistics are tough to interpret." Contrasted with articles that take one example (a 94-year old making a breakthrough in some field) and directly generalize it ("to be a genius, think like a 94-year-old"), this is a much healthier and saner approach to interpreting statistics. (I didn't make this example up; it was on hacker news)
