This article seems to be part of the recent wave of content about orthotropics/mewing. I'm not sure why it seems to have picked up so much recently.
I can easily see why this became mainstream, because it’s easy to do, and a sucker is born every minute. I am however, surprised to see this bunk here. Although, I’ve noticed that on health topics this forum is at its worst. Endless testimonials about vitamin D, magnesium, LSD, FSD diets and more seem paradoxically popular here, and I’m unsure why that is. Maybe the California connection?
