I think that gambling is fun and that you can do it till a certain point you get addicted.
Gambling has so much fun that if you once started the gambling it hard to quit. It as additive as a smoking to a smoker. As smoker cannot quit smoking no matter how dangerous it is for his health, A gambler can stop gambling as he always has a hope that on the next gamble he will win and it keeps on going like this. even if he wins, gambler wont stop because of the greed and continue to gamble till the time he is bankrupt.
That is why gambling is very addictive. Once you have experience the joy and fun that it can give no matter what how much you are losing into it. You will just going to keep on playing.
But in the end, if you are not able to play it and you are running out of funds you will just realize that gambling really is not a good thing to get addict with.
