Sometimes it is hard to determine just who is telling the truth. There are times when two people, who are for the most part very believable, are telling two different stories. Whom do you believe? How do you really know who is telling the truth?

During the last twenty years the lie detector business has been growing. While these tests are not used in court, they are being used more and more by businesses. Companies want to know if their employees are lying and/or stealing while in their employ.

In East India thousands of years ago those who were suspected of committing a crime were taken into a darkened room. There in that room with the suspect were only the person who would question them and a donkey. The suspect was asked to hold the donkey's tail and was told that the donkey would bray if he told a lie. What the suspect did not know was that the donkey's tail was covered with black soot. If the suspect was going to lie when questioned he would never touch the donkey's tail. The liar could always be identified as the one who walked out of the room with clean hands.
