I heard that Dumberican fatness has plateaued in the last few years. Wonder if the study controls for age and ethnic factors.

This being said:
* White-collar slave hours combined with long commutes by car can't be helping any. Time was that 40 hr per week meant 45 hr, not 50 or 55, with additional time spent answering email at home.
* People being priced out of neighborhoods that aren't utter pestholes, and thus having to commute 2 hr/day, gorging their yap-holes with fast-food on the way. Self-driving cars will likely worsen this...
* Chemicals in food, read up on obesogens.
* Of course, kids can't play outside or walk to school. It's sooooo daaaaaaangerous. Never mind that crime was much higher 20-30 years ago.
