Prompted by a long-ago (in Internet time) discussion on the blogosphere (see here and here), The Chronicle of Higher Education has done an informal survey of caffeine consumption among academics and found that they do, indeed, consume inordinate amounts of coffee and cola products.
Via memeorandum, where I see Jacob Levy, Jeremy Blachman, Brad DeLong (one of the survey participants), and Amanda Butler have already commented.
Levy raises the question of caffeine-to-body weight ratios, something that certainly calls for further study.
