Hahaa, and did you know that people can have hair on their teeth? At least in German - originally meaning they are so strong, courageous and "masculine" that they even have hair on their teeth, some think from "on their toes" or "...tongue"... and now it's come to imply that a person, usually a woman, is tough, brisk, self-assertive... and typically combined with prejudice... unfeminine, manly... In Dutch the last bit seems omitted, not sure.
If you read the study you will see that they injected rodents with samples from fibro sufferers and the subsequent changes to the animals brought about auto immune responses - they need to pursue this scientifically.
