Interesting. A part of me says "good," and another part of me wonders if this is just a bit too much. Then again, I've been watching "The Janice Dickinson Modeling Agency" on Oxygen (don't laugh), and it's creepy how much they focus on how "fat" the already quite skinny models are.
"The show, known as the Pasarela Cibeles, decided in September 2005 not to allow women below a body mass to height ratio of 18 to take part. One of the rejected models had only reached a ratio of 16, the equivalent of being 5 feet 10 inches tall and weighing less than 110 pounds."
