Ways Your Eyes Give You Away- BLINK RATE

Can you catch someone lying in “the blink of an eye”? Quite possibly. We blink less in some situations (e.g. reading, daydreaming and working at the computer) and more when we’re under stress -- and when lying. Most people normally blink between eight and 21 blinks per minute at rest. Watch someone like Lance Armstrong being interviewed and you may see him blink much more when responding to the tough questions, says Navarro. “But you can’t call everyone a liar just because their blink rate goes up, however.  Bill Clinton blinked over 92 times per minute during his deposition, which was a reflection of the stress he was under.” Factors such as dry air and pollen can also increase blink rate.
