Gambling is fun because it gives you that thrill and you feel adrenaline rush all over your body Cheesy It feels different when you are betting for money. Different feel, different kind of excitement.
Moreover, people find everything fun when it involves money. That's why gambling is fun.
Not all people find everything as fun when it involves money. Gambling is fun only when you know what you are doing, when you don't know what you are doing then gambling can become from fun to a nightmare. I am pretty sure those who lost their homes or even worse, some who sold their wives I bet they don't feel gambling is fun at all.
