Lead and the mind etc.

Article here (Yahoo! News). When I first read the title, "Lead linked to aging in older brains," my first reaction was "Duuuh!" - but when I read the whole article, it changed to "Interesting." It happens all too often, but maybe the inner cynic is good for something after all. (Maybe lead in younger brains causes a greater incidence of vacillating opinions? No, wait, that's just human nature.) Anyhow, for all my readers who are GenY or better, I dedicate this post to you. Just don't eat any more lead.

And now...a surprise poll. If you read this post, would you mind posting briefly in the comments section on how you found this blog? (linked to a friend's blog, Googled it, etc.)
