Consider it. If your sim dies, you are looking at someone who will charge to revive (Because he or she will drop in energy and need to pay for meals),...not to mention paying for the meals you need to green up. We are already limited in ability to interact or use items as ghosts, so there is still an incentive to be "healed". But with us having such limited funds, many of us will be forced to wait the 24 hours (I think thats the wait time) for automatic revival. Besides,...as a ghost,...You could earn money and not have to worry about greening.
