I suspect you are a fan of microexpressions. The first time I
  learned about them, I was so excited that I bought a set of
  teaching CD's for my computer "Train yourself to read
  microexpressions" - very well done. Did it help me? Naw I'm
  still bad at reading faces. Well, I'm not bad at it - I just
  chose to ignore it, as there are SO MANY VARIABLES in sorting
  out expressions. Anytime I try, I get a headache :D Just not
  part of my skill set at the moment. "
