The following is a Dark Horse clip about the significant increase in myopia in children, as reported in this Atlantic article. Bret and Heather have issues with the article, but confirm the myopia problem and have their own theories about it. And, at the end, about orthodontia. It's 30 minutes long—and there's a section in the middle where they spend maybe too much time on the concept of "heritability"—so if you can stand it, you may want to speed up the playback. But I highly recommend watching the video, particularly to parents who are concerned about their children's eyes and teeth. I guess that would be all parents....
As I've said before, Bret and Heather are not always right, and sometimes dangerously wrong. But they are always interesting, and impressive in their quest for truth and their willingness to follow where it leads them, regardless of the popularity of their opinions.
