Paul... I too wondered, just for a moment or so, about 'anorexic'. It seemed a little ... tactless, perhaps? The definition in Chambers includes 'marked emaciation', that seems a bit stronger than 'hungry-looking'.
I think there are lots of 'old' words, ie words we seldom use, still being used in crosswords. As well as your Mod, and my Heel and Char/Daily, there are plenty of others - I dislike Deb and any use or wordplay involving Rake or Roue (members of the Heel club). Any usage of tired, old-fashioned words sees the setter marked down in my mental assessment!
