If gambling is considered a fun like you said, gamblers will not be mourning when they loose. Alot of people see it as an opportunity to make money and become rich and that brings the bad side of it that they lose the little money they have most times. You can not win against casinos all the time. Only those who gamble sensibly with what they can not regret see their loss as nothing much, but they do not realize they keep losing what they could have saved for other things. Gambling is not fun.
Well if I may ask do people keep any money to be loss in any thing, the answer will always be no people take risk to make more those who gamble and called it spare money that they are ready to loss can't complete stated that after lossing they don't having the feeling of regret for lossing.
No Matter how hidden the feeling of making money in gambling may be, the zeal if the money superceded the fun, because no body will just go and have fun for lossing money.evety gambler know that risk in gambling mostly the losses is higher than wining but still go for it because they believe the can make more money if they Put more and also recover the losses they have made , as fun can't derive most to that lent which many goes in gambling.
