So, what's your stance on the 3-, 5-, or 7-second rules? Personally, it depends on the food I dropped, and of course, where I dropped it.

In other words, if I drop a piece of a shrimp tempura sushi roll on the floor of my home, you bet your cute little butt I'm picking that thing up, blowing it off and chowing down!

But potato chips off the floor of a commuter train? Um, no thanks!
