Practical Puzzle : Life or Death on Paper

One of the classic pratical puzzle is here I hope you will solve it and like it

Imagine that you have been sentenced to death in a strange country where there is a strange law. Before you are hanged you have to chose a one of the paper kept in a hat. On one "LIFE" is written and on other "DEATH". If you select paper written "LIFE" on it you will be set free. Now one of you enemy has somehow replaced the "LIFE" paper with another paper written "DEATH" on it. Now both the paper has "DEATH". This person gleefully informs you of what he has done and that you are doomed to die. You are not permitted to speak to anyone about this misdeed, nor will you have a chance to switch the papers or the hat yourself in time. How will you avoid certain death?

Answer : After you draw one of the papers, swallow it. The jailer will be forced to check the remaining paper to determine what the one you drew said. The jailer will of course see a paper with "DEATH" written on it, assume you drew the one with "LIFE" written on it, and set you free.
