Pamela Meyer is an expert on lying.  She's studied people for decades to find the main signs that they're not telling the truth.  And she put together this list from Lifehacker of the eight secrets of spotting someone who might be lying to you.  Check it out . . .

1.  Liars distance themselves from the subject.  Like, for example, how BILL CLINTON said "I did not have sexual relations with that women."  Saying "that woman" was a way to distance himself.

2. Liars use qualifying language.  Things like "to tell you the truth" or "if I'm being honest."

3.  Liars look you in the eye TOO much. They also don't fidget, and freeze their upper body.

4.  Liars offer up too many details.

5.)  Liars who are trying to avoid punishment are more likely to suggest strict punishments. For example, OJ's hunt for the real killers.

6.)  Liars put barrier objects between themselves and the person questioning them. Even little barriers, like picking up a pillow, or putting a coffee mug on the table.

7.) Liars repeat questions before answering them.

8.)  Liars point their feet toward an exit.
