If the OP wants that our chars got the urge to need to eat then we should do it consequent and walk this way to the end.
When our char has to eat there is also a chance to get sick or get bad food..ours chars might suffer by debuffs just like "Diarrhea".
And now imagine that in a dungeon..Tank stops right before the boss because he,his char in this case,has to poop..or even better he poops hisself during combat.Or he have to poop in the dungeon..damn oO
A little bit too much of realism eh?
