because......
any choice in every bodies life is actually a gambling
choose a wise husband from a bunch of boys is a gambling
choose a school to study is a gambling
choose a boss to work with is a gambling
so, gambling is addictive
no one can escape...
That's why they say life is a gamble. Every choice we make makes us either choose a good opportunity or lose an opportunity. In terms of real gambling, people get addicted to it because it's an easy way to earn money. However, people cannot notice that, if you some up your losses over your winning everyday, most people lose a lot of money because of it.
