It's said about brain that, "use it or lose it" — now, question being, do you think if person plays brainless gambling games such as slots, dice for major part of his/her daily routine, will it make him/her dull?
Edit: "brainless" as in playing gambling games that does not require using brain, I thought it was clear especially given examples.
Brainless? It’s just us playing games that we love to play without calculations that do not make us brainless. It’s just a matter of us being entertained and not about us increasing our level of thinking. Even in slots, even as we don’t have a perfect strategy, there are still those who like to overtake everything seriously and make it look as if they are calculative. They don’t place bets on it blindly; they just use their brain to manage their bankroll and keep their budget in check.
