drugs don't work and a very small percentage of those studies were actually published, christine. what we've got is a situation where people respond to the ordinary stresses of life and god knows we've got a lot of stresses now. but when they feel stressed, when they feel down, they and their doctors turn to a pill instead of looking at how their lives are unfolding. what we find when we put all the studies together of all the anti-depressants, it's only the most severely depressed people who get a benefit from the anti-depressants and then it's only one out of four of those very severely depressed people who actually benefit. >> meantime the other people are still either on their anti-depressants -- it's not as if the doctor maybe is changing their course of action and -- there's so many things to talk to you about. we're out of time. it's interesting as well when you talk about higher costs for health care in this country, what that means. we'll talk about it again soon, overdosed america, the book, thank you so much. really appreciate it. >> pleasure to be with you,
