SDN Members don't see this ad. (About Ads) http://www.nejm.org/doi/full/10.1056/NEJMp1202451 Its behind a paywall but I'd imagine most of you should be able to access it. I never attend lectures (stopped going like 1/3 the way through the year). Much more efficient and productive for me to listen to them at 2pm at 1.5x-2.2x speed, rather than 9AM where I end up falling asleep or spacing out during the lecture itself. Some of my friends are at schools where LECTURE ATTENDANCE IS MANDATORY. They have my deepest sympathy.
