I think gambling is a fun of life, but I won't be addicted to it! Many times I prefer to play online games!
If you play for fun it is a good way to enjoy yourself rather than playing for money and then regretting later as you will always try to recover the money and in that situation mostly losing chances are way too high which will result in the addiction at the end.
I do not think that most of the people play gambling for fun. Most of the gamblers play gambling only for making money, in fact they consider gambling as the simplest and easiest way of making money, but it is not so, because i have seen a lot of people who lost a money in gambling but still they are playing gambling for a long long time.
