I think its because its our nature to play gambling games and we have fun on it especially if you unexpectedly won in a game thats too much fun . I am a gambler and i use to play some and when i lose my alotted money to gamble i use to feel sad so that was my alarm on myself .
Yeah, it's something very reasonable thing if we do gambling. gambling system because it always gives us feel happy and sad moments, happy to also benefit sad moment and getting the loss. It's all a reasonable thing, but if we can't control yourself then it will all give you a bad impact for us
