RE: How much one can rely on a lie detector?
wooo!what a machine,by a great scientist.thank him for making that devices.And i like this quote

Well, it is very difficult to stay calm and to maintain organism in the same state when a person lies. I think as well that this device is quite curious from the point of view of testing a person, but as practice show it needs development.
