now, dr. marty, you've also recently completed and published a biography of martin luther, a lutheran who somewhat predated dietrich bonhoeffer. [laughter] what's the difference between with writing a biography of a figure like luther and be -- and a book like bonhoeffer's? >> there are far more similarities than i thought i would find. when princeton university press described this series and asked me if i would be a kicker offer of it, it took me about five minutes to sign the contract. it was a new challenge because i didn't know anything like this. the first thing you have to do if you're writing a biography of the book is forget about biological analogies. that is you don't want to say the book was born this way and went through adolescence and all those things. [laughter] they don't do that. but they have careers, and they change in the light of the passage of time. think of almost any book you read 20, 30 years ago and think of its reputation now. think of the vonnegut books and the books tha

dr. marty ma carry is a physician and professor at john hop since. doctor, what do you think the reason is. >> reporter: we live in a overtreated over medicated society. let's face it americans take too many pills because many of them are lifestyle pills. now with all of these pills laying around the home kids are getting into them more often. this study in the journal of pediatrics interestingly showed that one of the casualties of this over medicated society we live in is that kids are getting into number one sedatives, number two pain medicines and 0 number three heart medicines. they've looked at now half a million people over the course of a decade that have come to the emergency roomy sepbgs alley poisoned becausroom poisoned because they have got even into the medication. jenna: how dangerous is it for children under five like the study was looking at. >> reporter: remember, a child's medication is usually one-third or one seventh the doze of an adult: by taking an adult doze they essentially can be overdosing. sedatives can have the complicat

dr. carson, marty and grace, the books are all paid for, okay? [applause] yes. and i'm grateful. [laughter] let me tell you, i'm grateful. but i want to thank you for coming. but reawaken your virtues, you've got to reawaken the virtues in you, you know? no matter how blessed you are, no matter how fortunate you are, you can spend 20 years building something, and you can lose it in a flash. and the last thing i want to say is the virtue of friendship and relationships. you've got to take care of your relationships. not when you want something, not when you need something. you've got to take care of your relationships. and if there's one thing i think i do a very good job at with my relationships because they're very important to me. my relationships. i think i picked up the phone and called 70% of the people in this room because i really wanted you to be here. it was really important to us that you come because we want to not just reawaken the virtues in this room, but we need to reawaken the virtues of this nation and get back, get this country back on the track of financial sol

dr. david prezant is one of the doctors caring for marty. >> as you can see just right away, the lungs arek in a normal person and they're big. compared to marty's, which are small. normal people breathe about ten breaths per minute when they're at rest. but in marty, the lungs are much smaller. so he has to breathe 20, 30, 40 times a minute. and yet each time, he has to stretch a very stiff fibrotic, scarred lung. >> squeeze my hand, tight. >> by 2009, marty had been diagnosed with pulmonary fibrosis and a rare autoimmune disease called polymyositis. >> before 9/11 we were tracking our firefighters and we did not have a single case of polymyositis. since 9/11, including marty, we have about five cases of polymyositis. five cases, you would say, is a small number. but five cases compared to zero, compared to a population of middle-aged men that you would expect none in, five cases is a lot. >> something stirred up a full-on revolt in marty's body, and he was dying. the only option doctors had to offer, a lung transplant. >> marty was on constant oxygen. he couldn't go to the bathroom witho
