Some people just don't understand themselves and how to monitor their activities. I mean to be able to detect and know when they are no longer following something normally the way they used to and learn how to learn and adjust before it gets worse.
The detection is there because signs are also can be seen. But everyone is dealing with their denial stage and that's why even if they're all being monitored and can be seen.
No one wants to admit that they are in the signs of addiction. Little did they know, they're already addicted and even if people tell them to calm down, they just won't.
And that is because for them, it's best to get themselves the treatment they all want to be because with all that they wanna do is to bet and continue even if it's costing them everything.
