I agree that it is one of the problem of Gambling. Many people paly their money in gambling and even they got lose they used to play again and again for hoping to get won. In playing gambling people must know the sacrifices and disadvantages of playing. They must knew that in gambling there are situations that you wom and you get lose. You need to accept the reality that you are not always set to win. But if you know how to play intelligently and know when to stop when you are losing. You probably don't have problem in gambling.
