I am wondering what I can do when the red health status bar goes down but no one is sick. I've tried taking them to eat, drink, swim in the lagoon (when possible) and I can't be sure any of this is working because there is no movement in the health bar. Actually, I'm not sure why the bar is down with some kids, or adults who aren't sick or elderly.

So I'm asking for reasons why this happens, and ideas on what to do when it does. If you'd rather PM me, that would work for me.
