RED BRACELET to remind anarexics not to eat?

So I learned that wearing a RED bracelet is what anarexics wear in order to remind themselves not to eat...and wearing the bracelet is also for anarexics to support each other and understand each other, and share a passion of ana. Mary Kate Olsen and Lindsay Lohan were seen wearing these bracelets. They're nothing special, just a red string bracelet type thing. Purple is for mia (bulimia). My friends next stop in her "illness" is getting the bracelet cause she said that she's tempted to eat. What does this sound like?
