Man and women have tattooed their bodies for hundreds if not thousands of years. Wow, that's a long time. And while some tattoos have very little meaning, many are so much more important than that. They can have personal or social meanings that help people communicate without words. Certain symbols have been placed on hundreds of thousands of bodies, and will continue because they help people feel a certain centered emotion. Sometimes it calms them down or reminds of the world outside their own.
