What is a one-sentence summary of the following article?
Paying attention to what a person’s body movements (or lack of movement) are telling you can often reveal more to you than what they are actually saying.Look for behavior and body language that is different from what they normally do.  Is their body shaking or obviously tense? This is usually a sign of nervousness and nervousness is common when people lie. Liars sometimes try to make very little movement with their body in effort to control their “tells”.  This also gives away the fact that they are lying, because usually they are unnaturally still. Are they sweating? This is a nervous reaction people cannot control. So, if they are sweating for no reason, it might be because they are lying. This is often something children do. Fidgeting (tapping fingers, playing with hair, etc.) can often be a sign or “tell” that someone is lying. Wringing or clasping and unclasping their hands may also be an indicator of lying. Small eye movements such as slight narrowing or widening, darting around, and even closing (for longer than a blink) can be indications that someone is lying to you.  If someone immediately and quickly looks away when they begin to tell you something or when you ask them a tough question, they might be lying. Especially young children are often not able to make normal eye contact when they are lying. However, skilled liars have no problem making eye contact.   People normally glance away a bit when talking. A person who's making a point of keeping eye contact is more likely to be lying as they're probably trying to convince you and themselves that they aren't lying. Things like jaw clinching, lip biting, forehead wrinkling, etc. can all be small signs that the person isn't being completely honest with you.  Expressions on a person’s face, especially skilled liars, can often be limited to their mouth instead of the whole face, particularly when they are trying to control their expressions.  Is their nose red or are they scratching it? Called "The Pinocchio Effect", blood rushes to the nose when a person is nervous, such as when they are lying.

Observe their eyes.People often don’t realize just how expressive their eyes are. Study their face.Just like with the eyes, people are often not aware of the small unconscious movements in their face.
