Boredom is something that happens when you sit on your ass, and don't have an imagination. IE. If you are alone for one hour, nothing to do, no goals for that day, then you might get bored. Especially with the cell phone generation people forgot how to be alone. Being alone just observing your environment allows you to develop an active imagination. So to the point, you can't really get bored while you are killing zombies. Not sure how boredom is working in this game. But it should not decrease while you are actually surviving, scavenging, scouting, killing zombies, going through peoples houses, and belongings etc. People would have too much on their mind to get bored; like where do I find food? Or is there a zombie around the corner?. If you were holed up in an apartment for 6 months with nothing to do, then you might get bored and be slightly crazy. That's different than being an active survivor with goals to accomplish.
