9. Rock Eating
We thought eating glass would be tough enough on a person’s teeth as it is, but there’s a 44-year-old woman who lives in Bedford, Virginia who actually eats rocks, and she’s been doing so for over 20 years! It was the “earthy” smell of the rocks that initially attracted her to munching on rocks. Since her first bite, she’s been unable to stop and usually cannot go for more than a few hours without doing it. She makes the task a bit easier on her teeth by breaking them with a hammer first. One thing we’re pretty sure of in this case, and that is that she does not suffer from a mineral deficiency.
