In this graph I can understand how for example when I see people who play slots in person and do not stop, they have a behavior similar to that of the junkie who seeks the high of the first shot but never gets it, but one that gives him less satisfaction, while sinking him in the hole.
The graph is very illustrative.
I think this chart applies to all bad addictions, including drug addiction and alcoholism. All addictions develop cyclically and this is their danger, when a person's mood chart grows and he thought that things had gotten better, but in fact it is only a small increase before a new big fall. And so every time. Therefore, it is very important to be able to keep your character with a steel grip, and be strict with yourself.
Gambling is psychology, money and fun. But as it turns out, no business should combine so many aspects, because then it can capture all the attention of a person. And this is bad and unnatural.
