Maybe office work with less distraction? You can't be working on a machine and start thinking about gambling, you can't be an accountant and start gambling at work, distraction can affect your work, you can lose a hand or do the wrong calculations, I won't advice anyone to gamble at work unless the activities are less tasking, like they have a lot of time to fool around, I won't do it though, because I don't like losing the sense of my environment, I will like to gamble in my room right on my bed.
