" WASHINGTON - If that craving for chocolate sometimes feels like it is coming from deep in your gut, that's because maybe it is.

A small study links the type of bacteria living in people's digestive system to a desire for chocolate. Everyone has a vast community of microbes in their guts. But people who crave daily chocolate show signs of having different colonies of bacteria than people who are immune to chocolate's allure."

I suspect this may be one way of saying, "It's not all in your head".

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
