The past few days I have been craving candy to the point where my wife bought me some.
My daughter has a thing for pumice. I've literally had to remove my pumice stones from the shower because she eats them. She knows its not healthy and that it will ruin her teeth, but she has trouble restraining herself. Praytell, what exactly would her body need from pumice? If you can get to the heart of that, and I can prevent it, I might buy into the "my body needs something in it" claim.
