Anyone can be vulnerable to gambling addiction, if we cannot control our self, emotion and the extent to pleasure or something we like doing, another thing we can also consider is how discipline we may appear, there is nothing too bad in us going for what we want and doing it, but too much of everything is bad, because in doing so is the introduction to getting addicted, therefore we must be self-disciplined from how we are gambling.
Addiction is fuelled when the person doesn't have self-control anymore; when they can no longer differentiate their normal playing and when they are breaking limits, they don't see it as anything wrong, and they even start chasing their losses as a means of trying to recover money, and when they make a win, it's never enough; the eagerness to win more is always there, and their greed starts to control hem. It's just something that if one is not careful enough, they might end up getting addicted without knowing it.
