I used to be in the habit of biting my nails, but I've trained myself to stop that. I've recently picked up flossing, which I'm very proud of. Not enough people floss. You know what they say--only floss the ones you want to keep. I want to keep all of mine. Sometimes I have horrible nightmares about losing my teeth. I hear that's a fairly common dream. Isn't that weird how people have the same kinds of dreams? What do you think that means? Anyway, what do you do?
