Another big book about risk from Taleb filled with math, anecdotes, history and Fat Tony. This time it's all in service of his idea of anti-fragility: systems that are improved by stress and disorder. Again, there's a lot in this book that is over my head but I found myself highlighting and picking up quite a bit. He would argue that reading (and re-reading) difficult books increases one's anti-fragility and makes you better. So there.
