Thanks, Gizmodo, for bringing to our attention a new study from Aston University in Birmingham, England that proves the five seconds really does make a difference in terms of food safety. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped.

So next time you pick a Dorito up off the ground, yell “FIVE SECOND RULE!,” and stick said Dorito in your mouth, you can let your friends know that science says your behavior is A-ok.
