you do have concerns, you've maybe read about things, you dop necessarily believe the diagnosis you've been given. how do you make sure that's a productive conversation? >> right. because there is this huge i call it the biggest divide between doctors an patients right now. everyone is on the internet and a lot of doctors are annoyed because patients come in and hand people -- they hand the doctor this big stack of internet printouts. you go on the internet, you go to trusted sites like mayo clinic, cnn.com/health, and you distill what you've learned so you aren't handing them pages an pages from a printout. you say i learned, this, and maybe can we talk about this, and maybe hand them one page. when doctors have 13 minutes and you give them 25 pages of printouts, they can't read that. boil down what your questions are. >> it is always good to come in with a real good sense of what it is that's troubling you instead of i've got a pain. describe it a little more. great to see this. give me the book so i can hold it up. elizabeth cohen, the new book,
