how can you define money?.....under wat perspective? well you will probably say its a neccesity.....thats very wrong, its true but not to that extent of bieng a teaching tool......hmmm, how did money came about? it was introduced to replace commodities of no enough value for exchange with more valueable commodities.....then you have to concentrate on the value rather than the paper.....then the value you can get it in another form if there is no paper.....then you will realize money is only a game
