But I don't think that they should stop there. I think they should also add viruses where you could get a flu or cold from food that wasn't handled properly, this would greatly effect gameplay if they decide to add a hardcoe mode where you MUST eat and drink CLEAN liquids.
Viruses would be like diseases except they would be slightly worse and go away over time or make you worse if you decide to continue to be active and not take some sort of antibiotic.
Flame me or expand on the idea. :goodjob:
