Wow life or not life?

im on the assumtion that people think this is a life game as in it is life though u sit by a computer and play i dont understand when people say to me its not just a game when clearly it is is it a addiction yes i agree but i have a life out side of the game and i spend most my time off the computer....

my point being why is warcraft a life to most players? do they have no phisical contact with the outside world?

dont get me wrong ive been on and off the game for 2 years and i still will forever love it but its not my life and shall never be can any one enlighten me on this subject?
