Lie Detector

In the essay, "Lie Detector" the author describes what the body goes through when you lie. He basically says that lying is a strain on the body and that it is not natural. Although I never thought about lying in that way, he makes perfect sense. The lie detector is a machine that basically senses stress, which can be caused by lying. Since stress is a bad thing, we can conclude that lying a strain on the body. He also states that he isn't absolutely sure that it is bad for the human body. He just says that it might be the cause of certain health risks.
