All of us have our own hobbies and fun activities. Gambling is sometimes a blessing. That is if and when the player wins. But if not, and the player would continuously gamble and lose, then it's NOT good anymore. Some people who gamble even risk losing everything just to be able to have funds while gambling..
I know of some people who have lost their houses, cars and even jewelries just because they needed easy money as capital for gambling deals. Worst scenario are those who do illegal stuff just to support a bad habit.
