Farmville Game

Recently I have become preoccupied playing farmville in facebook. Oh boy my fingers are aching from clicking the mouse. Then I realized that maybe this game will ruin my hands. I hope not. Some of my friends told me that they are really addicted to it. I'm not sure myself if I am one of them. All I know is I keep planting and don't let my plants get withered. I harvest it on time. I am 3 days on this game now. What do you think?
