Milk and chocolate have being found to increase the duration of chronic pain. Most pain comes from inflammation and chocolate and milk feed inflammation on certain cases. Think of pain as a fire and milk and chocolate as propane feeding the fire. Neither caused the fire, but do keep it alive.
At least that's what I hear. I'm no expert in the subject.
I predict that the chocolate pill study will be catastrophic, like the beta carotene study; and that, one day, someone will work out that the fat and sugar are required to attract the attention of the gut bacteria, in order to get the good result.
Glad to see by the angle of his tie that Dilbert's testoserone levels are back to normal. I have no idea if dark chocolate has any effect...on the other hand, if the PHB gives some to Alice, I would reccommend that he wear a fireproof hazmat suit....
