I don't have much to add, but I wanted to register my support for the author as a counterpoint to the wave of hate he is sure to receive here for posting such a squishy complaint that's not backed by "evidence". I believe truly that he's right that a lot of geeks are in denial about their health and effects of there lifestyle. Of course this is probably true of most people in modern industrialized society, but the thing that's pernicious about geeks in this case is their power of rationalization is so well-honed. Plausible deniability is pretty easy with something as complex as health, but so is it with climate change as well. It's interesting to see how the personal factors affect the relative reaction to both of these subject matters by the general HN population.
