Hello Olga, Body language could many times tell someone is lying. There is a simple but so common lie, that mostly everybody does now and then. It is not really considered a lie though ,it is rather a socially accepted courteous manner. When you are not feeling so fine and someone asks you the usual 'How are you today?' ,most people will answer ' I am fine' ,even if they were not feeling that fine on that day. In that case the facial expression could reveal their real state of mind for example.

By mimics and voice, postures, gestures.

Not always, neither can nature, so I don't feel so bad about it. Which way? Any way that keeps you alive; can be color, think of a jaguar, can be the president. I liked what Bush said, "Read my lips". That's how you know when a politician is lying. In the end, though, it's education. That's why I am here. When are you going to sign up for lessons with me? B

but dont be too suspectable, cz in such case u can make a mistake and hurt the man/woman=((

Hi... usually you fell if it is a lie... listen to your heart!
