As psychotic as I have recently become about germs, I still held, somewhere in the recesses of my brain, a belief in the Five Second Rule. It maintains that a food item dropped on the floor but retrieved before five seconds have elapsed is still safe to eat. I always assumed that once my bone marrow/immunity issues were handled, that I'd return to following the Five Second Rule.
Wow. Read this article. Then know that anything you drop should probably just be put in the trash.
