Gambling can be fun activity, but it is not a must to pass on to the next generation. I even have no intention to pass gambling habit to my children. I never tell my children about any gambling activity. I hope they can get a better activity, the children aren't a must to be gamblers as well. It is quite surprising that you consider gambling as family business, I just can't imagine if most of family members get addiction. This will be a disaster because all of family members need a help, and no one reminds others to stop when they get addiction.
