I recently watched the original Terminator movie with my son (it's a guy thing). The first time I saw it was in basic training at Ft. Leonard Wood, Missouri, in the summer of 1985*. We weren't allowed to read novels or watch TV during basic training, so the Terminator was the only "culture" I saw that summer. It's burned into my memory.
If you've seen the movie (what's wrong with the rest of you?!), you'll remember the plot line that the fate of humankind is not sealed--we are not doomed to extinction nor guaranteed prosperity. In the early 1990's experts warned that, left unchecked, childhood obesity rates could hit 30% by 2030 (a Schwarzenegger-led robot apocalypse notwithstanding). So does the latest childhood obesity data, showing a flat line of ~17% from 1999-2010, mean that our prevention efforts are failing, or that we're succeeding at altering our destiny?
