That is one way to prevent gambling addiction which is to distract yourself with something much better like exercising. We know that people use gambling as an excuse sometimes a distraction to themselves where they can entertain themselves and forget all their problems, which can worsen their situation by just simply losing more money in the house. Plus sometimes they are not that aware of that addiction cause it's already been part of their lifestyles, unless someone points out that gambling is really bad if overdone. They wouldn't quit for just a day for sure, but they would think about it, and would take time for them to realize that gambling won't do anything good for them. I gambling as well, but I don't think that I can consider myself addicted as I don't think it about all the time maybe rarely when I have the time. It might be the reason of too busy in the world.
Physical exercise is an excellent type of activity if the player does not know what to do other than play. Sometimes it even happens that thanks to a spontaneous decision to play sports, it can switch our brain and we will stop gambling altogether and devote ourselves to a new and useful hobby. Of course, I understand that this will be very rare, but perhaps it will save several destroyed families. I noticed that professional players often play sports or were athletes in the past, probably this helps them achieve results and they draw some analogies to achieve their goals. They have a sense of purpose, but apparently they also have some other qualities that allow them to be more successful than others.
