yeah i can control myself when i playing gambling and i never play gambling for profit i just play gambling for fun and there is many people are playing gambling for profit and they face to high risk because i can not play gambling for profit i just play for fun.
Even playing for fun, you should feel some emotion I guess, otherwise why would you be playing it?
I know a few guys that even by just playing football, so no money involved, completely lose it, because they want to win it so hard that they get even violent when they are losing. So I don't think you are able to control it because you just play for fun. You are able to control it because that's the way you are, and probably have a good self control in other situations as well.
