It is a fact when we play that emotions are there on the surface, it is something that cannot be denied, in fact it is what makes us human, otherwise I think life would have no meaning, in fact we look for the casino to have fun and earn money, but in this case for me I have not found until now another way to control everything only maintaining discipline with money, and that is something that controls absolutely everything, that is why I say it, so things get very interesting in the game, if the money that is willing to lose runs out, then that's it.
You're right that emotions are what makes us human and it normal show emotions when faced or encountered with certain situations, and gambling isn't an exception, but as humans we have the ability to learn from an unpleasant experience that has caused us some sort of damage or losses, so as to avoid a repetition of that same event.
Gambling is something that can cost us a lot when we make impulsive decisions due to emotional imbalance, so let's say the first time it happened to us, it was due to ignorance of the situation, which is actually normal, but when the same scenario repeats and starts happening multiple times, it stops being normal and suddenly becomes unusual and abnormal, because nobody wants to be losing money while chasing momey and seeimg that this is the case with gambling impulsively, why not quit or start gambling responsibly.
