A good point, some really forgot their problem while gambling because they are more focus in winning. In my case, I am focus and entertained in playing so I don't really have any thought when I am playing, and I never gamble just because I have problems that I want to forget or to be solved, problems will never be solved in gambling anyway.
I gamble because I know I will be entertained and have a chance to earn money. But I do believe there are a lot of gamblers are playing because of their problems. However, do they already realized that gambling can make them earn a few more problems? Because that will probably sucks.
