I am a popcorn fiend...

And now I know why...

"An appalling example of our mindless approach to eating involved an experiment with tubs of five-day-old popcorn. Moviegoers in a Chicago suburb were given free stale popcorn, some in medium-size buckets, some in large buckets. What was left in the buckets was weighed at the end of the movie. The people with larger buckets ate 53 percent more than people with smaller buckets. And people didn’t eat the popcorn because they liked it, he said. They were driven by hidden persuaders: the distraction of the movie, the sound of other people eating popcorn and the Pavlovian popcorn trigger that is activated when we step into a movie theater."
