Dip Once, And Forever Hold Your Piece

The New York Times reports on some useful science out of Clemson.

On average, the students found that three to six double dips transferred about 10,000 bacteria from the eater’s mouth to the remaining dip...

Professor Dawson said that Timmy was essentially correct. “The way I would put it is, before you have some dip at a party, look around and ask yourself, would I be willing to kiss everyone here? Because you don’t know who might be double dipping, and those who do are sharing their saliva with you.”

So finish that chip. If you want more dip on it, use an uncontaminated chip as a shovel. And for civilization's sake wash your hands when you arrive at someone's home for the Super Bowl party.
