9 lives or what is Second LIfe

This idea explores notion of 2nd life (the online 3d environment)as part of our 1st (real life). Is second life really secondary or is it just an extension of our real life presented in digital form. Our Life's could be divided in to combination of sub existences, for example: 1st - Home Life 2nd - Work Life 3rd - School Life 4th - Romantic Life 5th - Resting Life 6th - Social Life 7th - Family Life 8th - Leisure Life 9th - Second Life Arguably all of above have a tendency to differ somewhat i.e.: One has a tendency to have slightly different attitude at home in front of their parents (one life), and behave differently when with friends (life number two), however all of these constitute as one life (don't they?)
