By the Seat of Our Pants

Business Insider notes a new article arguing that sitting by itself makes us fatter, even if we make a point of working out.  This is one of the more plausible arguments for America's expanding waistlines that I've seen.  Even jobs that weren't particularly strenuous have probably gotten less so over time, as more and more information gets funneled straight to our desktop rather than having to be physically retrieved somewhere.  I'm seriously considering getting one of those treadmill desks when we finally have the space.
