I'm sure it is. The fact is that a single person has much more time to do such things, but if a gambler has a family and especially children, he has very little time to take care of himself. A single guy is looking for ways to earn or entertain himself and all that can be provided in gambling. It's very easy to start playing out of boredom, and then believe that you can make money with it. Although it would certainly be wrong. And a married guy is looking for more reliable sources of income that will definitely bring money, even if they are not big, but guaranteed, of course I mean part-time jobs at official workplaces.
