I have read that folks from the Caucasus get the third degree, and it's clear they (whether Georgian, Ossetian or Chechen) have a distinct look about them, ranging from the unibrow and the 5 o'clock shadow at noon which are visible and the hairy backs, which (generally) isn't.
Quite possibly, and quite possibly with reason, in some instances. But not really connected with the original post - we’re getting a bit off-topic here now :)
