Instead, we get 20 words that "point out" the problem: "The kids from all over the world have been playing and practicing to get better. Ours are playing video games."
That's it. That is all Gholson offers -- no statistics, no justification, just a sentence that says "American kids are playing video games."

In other words, dancing causes cancer.
