Its not really laryngitis anymore because you can hear me now. Anyway, i hope it holds out. We had tea here and it should be good . Guest lets go into it and thank you for everyone for coming. Thank you dana for the great introduction. I will start with this question, mary, he works from spouts from various seeds, so what gave birth to grunt . Guest actually it was a seed. It was a chili pepper or cry was reporting a piece on the worlds hottest chili pepper. I was in india, and someone told me i was reporting on this chili pepper and this contest where people eat this unbelievably hot chili pepper and someone said the Indian Military weapon eyes to this chili pepper and i thought i really need to report on that so i went over to this lab, this science lab that that indian Army Maintains and talk to them about the chili pepper, which they never deployed because the man said it was prone to mildew. So, a kind of bombed. The chili exploding chili pepper grenade never was deployed, but wow i was there there were other interesting things going on. They were working on a beach repellent while i was there. That was just right it might alley. I do know a leech repellent, so i was kind of aware of where the idea came from. I thought military science. Thats look on the ball rolling. Host that roach of all thing is something i would like to ask you about, so all of your books are wonderful, scientifically enlightening and really funny and kind of breezy. Did you feel any sort of worry about bringing this kind of lightness are breezing as our humor to soldiers, which is kind of sacred in the United States right now your soldiers are our heroes and they sacrifice a lot. I did she feel about bringing your humor to that subject . Guest a lot of trepidation about that. A lot of concern i wanted i have two b me. I got a be me. There has to be a mary roach book. It had to be funny and have levity. On the other hand, like you said this is more and people are injured in many ways they didnt want to be disrespectful or make light of things in an inappropriate way, so i tended to make fun of myself as the clueless outsider that i truly was. For example, at one point i have a chapter on basically how to design a vehicle basically automotive safety for people who drive bombs. You know, how do you create a vehicle that will keep the passengers safe if a bomb comes up from underneath and they were showing me around this large Armored Vehicle and they were talking about how it had to be stripped down. You couldnt just keep adding more armor because it would make it so heavy and it would be too heavy for the engine, the brakes etc. , so very stripped down inside and i said its great you still have cupholders and the guy said, mary, those are rightful holders. [laughter] thats kind of what happened over and over because i really am not im not spent any time in the military. My father was very old, 65 when i was born. He actually enlisted in world war i. Made it as far as basic training where he got a hernia and that was that for the illustrious roach military career. Host so, in terms of your being this kind of person who blunders into these situations, you have covered some a subject in the last one was a bit similar perhaps to grunt, packing for mars where you worked inside a nass in the Space Program. Was it harder to get access to the military or to the Space Program . Guest you would think the military, but in fact it wasnt as difficult as nasa. The military is very straightforward. It was either this project either classified if it was not classified people were helpful and willing to kind of help me. The difficulty was, it wasnt that people were saying no, it was that no one felt they had the authority to say yes, so you had like 15 people that said i cant say yes, but i think you have to ask these people sort of pink pony back and forth so it took a year and half to get on a submarine. Again, it was just trying to find a way on their. In that case, partly because i wanted to be only on for a few days, not a month. I do like to immerse myself in reporting, but it has its limits. Host the good news is you can get on. The bad news as you will be on for 12 months. Guest exactly. Host the beauty of your books is in the details and there are details that are unforgettable and one for me is that in a chapter about military uniforms you mention the Us Government button specification guide picked the button specification guide is 22 pages long and i was amazed to read the army requires the clothing designers have a Fashion Design degree isnt that sort of eight oxymoron . Guest you think so. Surprise as well pick the woman i was talking to in the design lab where they designed basically accessories for being a soldier, the things you carry, the things you sleep in, the tents, sleeping bags whatever. They have a design lab for the uniforms and this woman had a fashion that degree and her background was in the swimwear designer and i thought that makes no kind of sense to me and she said if you think about it does because a bathing suits is for a specialized activity, athletic activity in a specialized environment. Is water, so it has to give, it has to react to the water in a certain way, so in fact she felt her background in swimsuit design was in fact a fairly appropriate one and the other when there had worked for highend wedding gowns in boston. She said here again, its layering of specialty fabric like body armor. [laughter] guest what certain marriages might need. Host one thing we learn from your book is that some things you would think would be of great danger to soldiers like sharks say if they go overboard are actually no problem at all, but some things you dont think about like diarrhea, which was mentioned are a gigantic problem. Why is diarrhea such a grave problem for soldiers . Guest will, let me tell you. [laughter] guest first of all, historically diarrhea was doctor william armor had a great quote, father of modern medicine. I dont know that much about them. He was one who said dysentery is been more fatal to soldiers than powder or shots. Statistics bear that out. The Mexican American war was a good example. Seven soldiers died from dysentery and disease, mostly dysentery versus one killed in combat and what would happen is you have these camps and you have the mess tent where you prepare food, no refrigeration and you have like pit latrines and flies unbelievable number of flies also attracted if anybodys were around, so the flies are landing in the latrine material and buzzing over to the beans which were sitting there in the flies would land on the crap and then have these patches on their feet and then they would not collate the food sits there for two hours ended in the whole camp gets dysentery or yellow fever or typhoid fever, so it was a tremendous problem. Now, its not because there is good hygiene on basis. The bases, we have air conditioning, so the whole Dining Facility could be sealed and you never had to open a window, so there are no flies anymore, so thats not a problem, but it is a problems and special operations require in a small units or small village in somalia. Those people are eating with the locals eat in the waters often not safe in the food in the rates of diarrhea with those folks are very high, twice the rates of ordinary listed soldiers. You can imagine if you are going to take down Osama Bin Laden or whatever your assignment was an you had extreme gastrointestinal urgency, that is a problem for national security. Host do they have any miracle drugs we dont know about . Guest they were testing. I went all the way to djibouti, africa, for the diarrhea chapter. Thats just the kind of gal i am. A lot of special operations, navy seal etc. Going out to barrys yemen, somalia, north africa and i went with a diarrhea researcher who is testing a very quick one dose regiment where you would be back on your feet in a matter of hours rather than days, so thats one thing that they were testing. Host topsecret. Guest actually, it will be coming soon to a drug store near you. Host one thing that was interesting is that we take for granted that mexico is like the poster child port travelers, but how mexico when that honor was kind of interesting. Guest if you go on to a database of all the medical journals, most of them anyway, and you put in diarrhea and guadalajara youll get 35 journal articles. I feel so sorry for guadalajara. Its like synonymous with diarrhea because herbert dupont, the god fire godfather of diarrhea research, honestly this man has done more for counteracting diarrhea than any man on the planet. I dont know if hes retired, but he thought where people getting sick and he set up a lab in guadalajara at the university using students and tourists as his study subjects and published in a lot of papers out of what a lahar sp1 do you think the reason hes never won a nobel prize in medicine is because the Nobel Community is embarrassed to call him up . Host so, you dressed up at one point for this role as a newbie journalist and some these situations. As hyperrealistic as the trademark and these medics and corpsmen in training are coming in immersed in this scenario, very intense, pyrotechnic sound real and looks like rifle fire, some of them are amputees who have a latex fleece and a backpack with stage blood that is pumped at an accurate rate and Remote Control for the bleeding and when the corpsman is putting it on properly it is bleeding slow and if not properly the actor gets very quiet and instructors are screaming, very tense scenario. To get close enough to see what was going on i requested a role, and suggested i play a journalist who gets injured, typecast. That is what i did. Host how did the doctors do . Did they keep their calm . With their confident about their abilities . The difference between the two day course, the first round of simulations versus the last was determined this difference. The first one, there would be a guy picking up a stretcher, the other guy on the other end, the patient falls off, its strong the way, backing up and instructors using a lot of words i cant use on cspan2. Host in the spirit guest your adrenaline keeps going, the loud noises and startle response from gunfire even though it is not real. That is important because the fight or flight response, is great if you need to fight. Cut and Emergency Airway or a turner cut, someones lung has collapsed. And flooded with adrenaline, makes you shake. And i was afraid for my life, you definitely is not a relaxing afternoon. Host you became a method actor. One thing i love about your books is scientists you never hear of. Some obscure form of research, what a trolleys what qualities attract you when you do these books . A testament to scientists in general, they tend to be interesting people. I had no idea what george peck would be like. A self fly and maggot guy, not what i expected. The philosophical soul who loved nature including maggots. They are used to explain, maggots in a will perform the amazing function, encouraging growth of new tissue fighting infection in that way. If it is done surgically in world war ii, horrible rooms and take the maggots out, he was looking into using maggots in walter reed for all the injuries. Host injuries . He tried to put this on me. And they were hurt by iuds. Sorry. That is all right. When an ied goes off, a buried explosive, stand and dirt goes into the wound. Maggots into the armory of the surgeon, to get people okay with that. I raise the clutch of maggots for you. When you arrive they will be the same age as the maggots we introduced into wombs. And had dinner, george peck went away, he came back with what looked like a cut glass bowl with chocolate pudding. They love to eat, he took them, on my fingertip, whatever when you take them out of the rotting body, they are very cute. And he was like those mandibles can do what no surgeons kabul can do. Tremendous respect and passion for these little creatures. I didnt know what i was getting. Have you heard from george peck . To thank me for the book i dont know if he read it but i didnt get feedback. He and his maggots are the most memorable however many maggots to be in contact with. The strangest programs, armies create a truly noxious stink bomb. It wasnt really a bomb. What actually is it . The world war ii one or the more recent one . It is a horrible smell to clear a room. I did have an odor and which is the most effective, cross culturally in any context. Were i not here, that perhaps i might [applause] what is metaphorically open the stench soup and hold our noses. Stench soup is interesting. Chemical census center, works with bad smells, something that smells like a real latrine and you want to have you start with a latrine. And they carry little bottles. Burnt hair smell people and rape them. Where they present, unpleasant . Did you find this odor frightening . Did you find it edible . It was hard to find a smell that anyone would say it is universally horrible, Something Like 3 of caucasians, it is wearable. The one one out, feared and hated all over the world Us Government, a compound in world war ii testing to treat the order and a standardized compound. An open air, hot day. That was the starting play but only the starting point because if you want something not at all familiar, if you cant place her know what the smell is it might be dangerous. It is not only repulsive and scary. The diabolical part, if you are designing a mellow to rent, if you approach a new smell, you know what it will be. It is fruity and lovely and that encourages you. If it is a wine description, how would you describe it . With a robust latrine center. The resulting product was called stench soup. When you were on fresh air with terry gross you said you are not easily disgusted. That is clear. Were there any moments during the writing of this book when you wished even for a moment you were writing about the wine country, napa or something . No. I think probably the closest would be pam dalton sent a bunch of vials to me well named vial. Those were gag worthy. Im not a gag or in general. Where did you open them . Out on the deck. We were not opening them indoors. That sounds like fun. I hope your husband wasnt reeling at the time. What was the most fun you had working on this book . Ever since, have you ever seen the film das boot . I love that film. I have been fascinated by submarines and the opportunity to go on board one out at sea, took a long time to set up but it was really interesting. You are on the trident submarine. How long . Four days. Did you have the run of the place . No. There are parts that are offlimits am a secret, classified information. I was in the enlisted crew lounge at one point and in the corner is a computer printer and it was labeled secret printer. Secret printer. I kept hanging out in the crew lounge hoping somebody would come in on the secret printer. A Nuclear Reactor, the idea is to stay down a long time. The idea is not to be seen or heard, strategic defense, a third arm of it, being down there under the water for a long time, they dont have to be in Nuclear Reactor never to reveal. They can state a long time. My was down 5 days. I went down with a group of prospect of commanding officers, i can go out when they were coming back. Where did you sleep . There are no deluxe accommodations. The closest thing to deluxe accommodation are the people whose beds, a bedpan, the mattress pan is a bunk and some are set up between the Nuclear Missile silo. The missile compartment, the stacks in the University Library is four levels, very high silos, very quiet, not much going on other than armageddon. Armageddon or nothing, very quiet. People who sleep there get a good night sleep. Otherwise four or five to iraq and some submarines where depending how big you were, had to roll over to get out and get back on the exact floor going the other way. You got to see different phases how the military operates from uniforms, submarines to the work they are doing in surgery, if you were the roach in chief of the armed forces, and could suggest one change from what you have seen in the military, what would you tell the commander in chief . What would you say you would like to see changed . What was suggested in brainstorming session, at Wrightpatterson Air Force base in the 90s for nonlethal weapons and there was a guy, a compound to create feelings of brotherly love. I thought he meant something that could spray over t
