to be honest i never know why gambling so addicting but i think gambling is like a drugs could affect the humans brain every time you're trying to stop then will be more often you will did it
No it's different gambling will not majorly affects human brains in gambling, it affects first you heart because of the emotions going on that would lead you to a poor decision making.
Not all people affecting their human brains when doing this kind of game. And not all the time you are always loosing the game and also winning. But I guess loosing is a majority result when it comes in gambling. You can not use gambling to gain a profit.
