Too often I've discredited the notion of positive thinking. For me, it gets a bit too New Age-y/preachy and bastardizes the law of attraction I studied in my psychology courses. (Blame it on "The Secret"). For a new study to show that there is some truth behind the popular notion is both heartening (so easy, anybody could do it!) and suspicious (...really?), at least for this girl. Will this work? As someone actually looking forward to aging, I'll have to round back to you in six months...!
