The benefits of mediocrity: "Straight-A students are more likely to develop bipolar disorder than their more mediocre peers, at least in Sweden, according to a new study of more than 700,000 former high-school students. Within 15 years of sitting their final high-school exams, aged 15 and 16, at least 280 of the students were diagnosed with bipolar disorder. After taking into account their parents' income and education-factors that are known to affect exam scores-the highest-achieving students were more than three times more likely to suffer from the mental illness than their average peers." Also? The worst performing students were the most prone to developing schizophrenia. Probably best to just be dull.
