Another Useless Study

I don't know why some of these scientists bother. I'm talking about some study that indicates you can run lab tests for chocoholism:

For the first time, scientists have linked the all-too-human preference for a food -- chocolate -- to a specific, chemical signature that may be programmed into the metabolic system and is detectable by laboratory tests. The signature reads 'chocolate lover' in some people and indifference to the popular sweet in others, the researchers say.

Pffft. All the smart peeps know that the test is much simpler. When you ask a chocoholic "Do you like chocolate?" if they moan and say "Oh, yes, PLEASE," well, there you go.
