A basic fact of life is its necessities: Food, clothing, and shelter. Gotta have those to live, right?

I focus on the first of the three, of course. A recurring thought I've been having recently is also pretty basic: We cavalierly call a favored class of this necessity, this building block of life, "junk food." And, for most people, it's an everyday choice.

Willingly, so many of us freely build our health on a stream of junk.

We think we're so smart.
