It doesn't make sense to me that the player in this game can take multiple scratches, bites, and blows and not make a peep from the pain. I'd think most people, in real life, if they were bitten, would scream in agony. This may make the game harder if it were implemented, but I would think it would increase the realism of the game. As an offset to this feature, a trait could also be added that could do something along the lines of making the player less likely to scream or whimper in pain for minor injuries.
