I don't think gambling should be called a addiction it's not something bad or horrible as it's always is portrayed. Not all our alike, not even our fingers are the same size, each one finds a different passion which keeps him sane so I would call it a passion, i believe each person is sane enough to decide for himself, and so I feel each one can make his own choice without being subject to humiliation.
Only people who do not have a future will consider gambling as an interesting thing. The fact that gambling is a bad thing and has no benefits. As people who want a much better future, we must try to leave the gambling game in the fastest possible time.
Don't think all people with no future only consider gambling. More individuals with higher level of life status had more fun times with gambling, rather that other activities particular on sports. Other frustrated persons might be leaving gambling for good but, after all sorts of pain recovery they tend to go back the usual habit. Happiness in gambling cannot be measured specially a person who wanted to live life to the fullest.
