3 out of 5

Would someone please tell me how, in a family of me plus 4 guys, only me and the 4 year old have avoided this nasty bronchial crud going around? The two older boys are at school all day around other kids but they are old enough to wash hands often and cover their mouths, etc. My husband is at work with a bunch of adults who certainly know how to keep things sanitary and he is very particular about keeping everything clean. So why do I, who gets smooched and hugged by every unhealthy creature in the house and the kid who hates to wash his hands (ever, after they've been Lord knows where, ) seem to be the only ones still hale and hearty?
