  I do find untangling knots in yarn to be
relaxing, though.
         
 It's pretty
  satisfying to solve a particularly nasty one.
I'll never understand
 how those knots form in the middle of a very regularly-wound ball.
         
 I have never understood how calbes seem to defy the laws of
 topology and
 tie themselves into knots.  But prectical experience shows
 that and set
 of calbes left lying around will knot themselves together in a
 ridiculously complicated way.
       
 A topologist recently told me that "tangled" was the normal state.
She said
 the reason was there was basically only one topological conformation that
 was "untangled", and many that were "tangled" so any tanglabale
object will
 tend to be in a tangled state.
