We’ve never abided by the “five-second rule,” which says if food hasn’t been on the floor longer than five seconds it’s safe to eat. We use a slide rule. We go from five to 10, 15 seconds, or even the day after.
If it’s chocolate, there is no time limit. Pick it up and have a look.
As for a recognizable bit of a cookie, sometimes it’s easier to pop it in your mouth than walk to the trash can. Oh, don’t tell me you’ve never done it. I’m smarter than that. Remember, I use a slide rule.
There is a direct correlation between willingness to eat something that has fallen on the floor and the desirability of the food. I’ve yet to see a kid scream, “Five-second rule!” when cauliflower hits the floor. Right now, I could probably assemble an entire vegetable medley with bits and pieces the grandbabies have left under the kitchen table.
