I should have said post the actual study. But as you point out some people do have an interest in the article. I did not mean to be accusatory to you, rather that articles like this gloss over important realities. The article itself is just an amalgam of chirpy quotes. The hard data behind those quotes is no where to be found. That's all I'm saying. Clearly it is not your fault thall, and I didn't mean to attack you. Peace.
