Cold flickering

How about when player has cold, his hands literally shaking especially when aim with a gun or something?
The more you’ll have cold (in terms of numerical value), more it will be difficult to aim steady (with even a heavy breath SFX?).
What you think?

Actually I’m afraid this feature maybe is already in the game, but I had never notice so I’m guessing it’s not… however if it were, I say sorry from now on for this post instead to checking from myself.
