Hey, did you hear that ice chewing is all the new rage? New only in that the Wall Street Journal is just getting around to writing about it, but people have been chewing ice since the 50's when those fancy crushed ice machines hit the scene. We like to partake every now and again ourselves, but since we stopped drinking soda we've been kind-of limited in our hook ups. Anyway, apparently habitual ice chewing is linked to iron deficiency. We were told it was also linked to sexual frustration, but we were told that about everything we do that's even slightly annoying.
