Oh my goodness! I am so sorry to hear that! And what an e-mail you received from Goldi. I didn't know that kind even existed. What generation is your family in?

It's always a good idea to cure illness's as soon as they occur so that they don't develop into something serious. I check my peeps health bar before going to bed at night and if it looks like it's beginning to drop (indicating an illness is likely forming but not arrived) then I pause the game until I have time to monitor it better.
