       | and the hip-flexors are connected via the vestibular system.
       | Which means, you can do all the excercises, chirpractics, yoga
       | and so on, and still suffer back pain, because the hips don't
       | relax.
       | 
       | The demonstration was: molars and canines have to have contact,
       | if they don't the vestibular system is out of tilt, put a piece
       | of plastic between them, hip flexors relax, hips get their
       | mobility back, back pain goes away.
       | 
       | Tried it... worked!

         | Does that mean if they aren't touching, your hip flexors relax?
         | Or the piece of plastic makes your molars and canines touch
         | which causes your hip flexors to relax?

       | Just a few days ago I was reading "Thinking with demons," an
       | excellent history of ideas about witchcraft in Europe, and was
       | struck by the following passage about a 16th century drawing of
       | three witches by Hans Baldung Grien:
       | 
       |  _Informing everything in the scene, and establishing
       | iconographically that it is indeed a scene of witchcraft, is the
       | gesture of the witch who, bent on one knee, stares backwards at
       | the world through her own legs. According to a contemporary
       | German proverb those who adopted the pose would be sure to catch
       | sight of the devil. This is perhaps the reason why the motif is
       | also found among the monsters and devils who populate two widely
       | separated versions of that most demonological of picture
       | subjects, the temptation of St Anthony--those of Hieronymus Bosch
       | (c. 1490s) and Jacques Callot (1635)._
       | 
       | So it was fascinating to learn from this news article that "There
       | are also regions of Japan where the folklore says that one can
       | see ghosts, the world of spirits and demons, or the future by
       | looking upside down through one's legs."

       | The first sentence is manifestly false. If you take the example

       | Either the image represents a different illusion or (and I guess
