Interesting article; I believe it. I was just expressing to someone yesterday my opinion that people get addicted to things because they don't know how to deal with boredom.
The cures for the anxiety issues that are often a part of addiction recovery are practices like breathing techniques, meditation and what not that could very accurately be described as boring. There's a deep connection there, I think, but I'm too foggy-brained today to try to be eloquent about it.
