What is the most irrational thing in game?

Game is always just a game even if you try to do it as immersive and true as possible. There will be those irrational things and features that are needed that game mechanics work. In your opinion, what is the most irrational thing in DayZ? I have two top favorites: 1. I can be pouring rain that makes all your gear soaking wet in seconds but you still can die to thirst at that same time😂 It is actually strange that you can’t use rain water and drink it. 2. You can’t find a piece of glas or sharp metal to work as a knife but you can just grab two rocks and you have a knife🤯
