Trivia is a union of the brainy bookworm and tabloid worshippers. Playing trivia will teach you random stuff that you will probably never use again, but it is a fun way to exercise the brain. You are required to remember information that you don't usually use. This act of searching for information is a gentle mental stretching exercise for the brain. Playing trivia is a fun and relaxed way to learn new information, and keep mentally alert and aware.
