Why not research what RESEARCH is --- if you did, you would better know what it is, what its' purpose is, its'methods, etc. You might even discover the importance of being able to document and reference your sources. Asking a singular question to get a singular answer to that question is not research. It never has been, nor will it ever be. You are simply using the lazy person's way to "knowledge" and giving an excuse ahead of time to justify your laziness.
