Psychologists have reported that if we watch an hour of television every day, our weekly expense will go up by US$4. This is because the advertisements on television can induce us to buy things we don’t need. Also, shopping with a credit card often results in spending more than what we would with cash. As a credit card is not real cash, one tends to pretend that no money has actually been paid out. It is however a different matter when we feel our wallet get lighter and lighter. This is all just psychological.
