A myth that says that if you drop food on the floor, and pick it up within 5 seconds then it's okay to eat. But research done at University of Illinois has disproved this, and says that food picked up in under 5 seconds had a significant amount of bacteria on it.
"Ewwwww! Your gonna eat that? It's been on the floor!!" "Yeah, 5 second rule."
