For many people, gambling is the best spare time activity that they enjoy doing especially in the weekends. I'm not a big gambler. I play occasionally but it actually feels good to play and win. It makes you feel exited and hapmy especially when you play with people you know or your mates. I don't see gambling as a need to do activity, but it is a great choice when it comes to having fun.
People feel it's a must to gamble because they have got addicted, actually they want to leave gambling forever, because it was never easy they just moving forward like a zombie, I do believe the real circumstances are like that. Fill in your spare time to gamble would only result additional problem instead having fun.
