I'm a bit too loosey-goosey at the moment to put together a coherent narrative, yet I've got lots of material I'd like to pass on.
Like this article by Michael Pollan about why twinkies are cheaper than carrots. Frightening and fattening!
This article, also from the NYT dining section, about the joys of processed foods.
And also this article, about how you know if your dog likes you.
My speculation: Your dog would like you even better if you fed him twinkies. But not for long.
