Could you live in a virtual world?

Take a look at Ready Player One by Ernest Cline, on the shelf in theTeen Zone.   Wade Watts escapes his grim surroundings in 2044 by spending all his waking hours in OASIS--a virtual utopia that lets you be anything you want to be, a place where you can live,  play, and fall in love on any of ten thousand planets.  Like most of humanity, Wade dreams of finding the hidden fortune that lies concealed within this virtual world.  Go along on his quest in this world where the lines of distinction between a person's real identity and that of their avatar begin to blur.  Could you live in a virtual world??
