Lie Detector

Lie detector tests are an almost fool proof way to tell if someone is lying to you. They measure a number of things like heart rate, skin movement, breathing rate and compare results at different stages of the process. The test itself has several stages, first the machine records the factors named above whilst the examiner has a normal conversation then compares it to the results produced when they ask the questions you require the truth from. The most common use for lie detectors is for extra marital affairs. The results from the test are almost always conclusive however it is possible to beat the lie detector but you would have to be very skilled to do this.
