For guys that are in the Pickup community, some of us are better at reading body language than others are.

With that being said, my question is what are signs that a man should look for while in a conversation with a woman.

Now i have a basic understanding of "Body Language" in regards to reading how her body is tilted and such, but what I would like to know more about is involuntary body language (i.e. blushing, giggling, eye-rolling, etc.)

There has got to be surefire signs of a woman's interest or disinterest that she cannot control that is obvious to see. What are they?

Feet don't lie. As the author of What Every Body is Saying, Joe Navarro states the feet and legs never lie. By this he means the higher you go up in the body, the more control one can exert in presenting themselves in a certain. The limbic brain apparently has almost full control over the lower extremities hence his recommendation to look at the feet and legs as behavioural cues more so than the face and upper regions of the body. I wouldn't rely on any one area of the body but more a holistic/overall picture including the body, context, and other variables that may be relevant to reading somebody.
