If you were going to be a jeopardy contestant name a specific area you'd want to memorize?

There is a Website that keeps a record of the previous Jeopardy questions and answers for a large number of shows. The records go back to the I st Alex Trebek season in 1984 with a records for a couple dozen of those shows. The site has almost a complete history of the questions and answers given for at least 2,000-3,000 episodes. The site is called J! Archive and says it is a Fan created archive of Jeopardy games and players. The site claims almost 200,000 clues (questions and answers). That might be a better starting place than trying a specific area to memorize. A link to the site has been added under the related links below this question's answer information.
