Interesting article about misery and BE levels. Seems like BE can be sparked for all kinds of reasons from misery to a runners high. Because an activity encourages a release of BE, does that always mean it is an addictive behavior? There must be another factor in the equation that creates an addiction. As many people don't go back to misery to get a BE rush or become a runner to get the BE rush. I don't know, just putting this out here.
