Can I become a Software Tester if my education and background are not computer related?

In difference to Software Development, Software Testing open for the people from other industry domains. For example, if your background is in economics or accounting, then companies developing financial and accounting applications will be happy to hire you as a tester. Or if you are doctor or nurse, than you will have a value for the companies developing software for medicine or pharmaceutical industries. A former pilot would be a great tester of air traffic software and former school teacher for educational, School Management or Course Management applications. Why? Because a software tester is validating software from the user point of view and being a subject matter expert will help to uncork potential problems easier.
