♪ >> from studios of new york city, this is "charlie rose." charlie: the gop front-runner faces new challenges in tomorrow's wisconsin primary, where polls show him trailing ted cruz. joining me is robert costa for "the washington post." he recently sat down with trump. his son and others, joining them.

we are pleased to have bob join us at the table. how did this come about? robert: woodward said, we would like to sit down with you at length and talk this through, and we had a conversation and we tried to ask him about the presidency in washington, that is his prized property. we wanted to ask him about the presidency, how he would actually be as president, to get away from the day-to-day campaign. charlie: what was the setting? his son was with him. who else? robert: when trump is in the room, he is in command. we're supposed to have lunch, and there were all these images -- sandwiches around with no one touches a sandwich. no one even has a drink from the trunk water bottles. if trump is not eating, no one else is eating.

we are sitting at this construction table surrounded by secret service. charlie: is he doing more interviews now? robert: he is doing more longform interviews. he recognizes that the kind of needs to pivot to show some depth on policy, depth on character, as he almost tries to reintroduce himself to the country. charlie: lots of people writing about them, and he noticed he had a bad week. how did that affect them? robert: he is confident publicly. his campaign is a tightknit group. they had been privately rattled. they are trying to rally each other as the media has more scrutiny, as the republican establishment thinks about an open convention. but trump, as the leader of his own campaign, is starting slowly to bring people in, some --.rans, he recognizes that if he is really going to be the nominee, he needs an expanded team. cap delegates. that is something trump has been

behind on. if there has been one vulnerability, it is on organization. he is not winning the delegates at the state conventions that take place after the contest. charlie: who do you think has the most influence with him? robert: his daughter, ivanka. and his sons are close to him. he sees ivanka as someone who has poise, an outsider to the process. his campaign editor has been influential. another person i was here, steve wynn, the casino magnate. he helps connect trump with people in washington. i said, who put you in touch with trump? he said, steve wynn. i found this with other people. he has friends who are trying to connect with them. charlie: they were very competitive in atlantic city. and a little bit in las vegas.

robert: when i have spoken to trump about his relationship, this is a trait of trump year after year. he loves to fight, he tests people with business and politics and how they respond to his combative nature. if they can get over that, he often becomes friends with them. he said in the interview, he said to woodward, after this fight is over, watch, i will become friends with cruz, maybe not jeb bush. he thinks the force of his personality can become a uniter. charlie: roger stone has what influence? robert: this is a great story about how trump operates. stone was getting uneasy with campaign. he was not comfortable with lewandowski's rising role. he was want to be the right-hand

man for the campaign and he saw his influence waning. he did not like that trump was not listening on policy, stone was writing all these memos that were getting discarded. when trump heard about stone leaving, trump called up the "washington post" and said i am firing stone. charlie: he is not leaving me, i am firing him. even know it was not true. robert: exactly. it says to me that is how trump operates in public life as well as private life. he is a brawler. he wants to come out on top. everything about him is winning. the thing is, he's still friendly with roger stone. talks to sell regularly on the phone. wants advice from him. he has a tight circle. stone has been a part of it for 30 years, and they are still chatting. charlie: people who are not part of the campaign per se, but have his ear. who else? robert: the most influential person right now, senator jeff sessions of alabama. someone who is not part of the

new york world, but he has been there to be a connector for trump on the conservative side. sessions has been savvy putting his own people with any trump campaign. charlie: he talked about the lone ranger, that he was the lone ranger he saw himself as that. what is that about? robert: i prompted it. i asked mr. trump, you seem like , the lone ranger he grew up in the 1940's and the 1950's. he loves old tv and old sports figures. would be maybe he something he picked up on, and he immediately did. he said, i understand life, i am the lone ranger. he likes to be the loner. charlie: has been a loner all his life? robert: he has been social all his life but -- people in business communities know trump, but he is not part of the club. politically, and in business he , is a celebrity and he is famous, but he considers himself

to be someone who is outside of the mainstream. charlie: therefore, you can -- he can easily run against the establishment. the idea, also, is that he is thinking about, as you said, defining himself as more presidential. he talked to maureen dowd about that. she wrote a column on sunday in the new york times. she ended that column by saying, "start." what's he going to do? robert: he won't start. she was so savvy with her column, and she got trump to say, i know i need to change. but he is so reluctant to advice , from advisors and friends, even his family. charlie: what he also says is, i have to win first. it seems he is saying, my game has always been about winning. after i win, after the game is over, then i can become a different person. robert: you look at his friendship with his first wife, with his past business foes.

he thinks he can destroy people publicly, call them little marco jeb, thenrgy jab -- win them back. charlie: his natural inclination is to win, and after i win i will be so presidential you will not even recognizing. you'll be falling asleep will be so bored. robert: a lot of people in washington, they worry that trump is not doing it fast enough. he's not getting the delegates, he will not be the nominee. eventually you have to turn the corner, the fight has to end. charlie: you are an analyst on nbc, do you sense that? that somehow he is incapable of turning and therefore it may be too late? the opinions against them might -- against him might have hardened? robert: it depends on what happens on tuesday. if cruz can come out with a

victory, if he can get momentum that will help them with the establishment in washington. the thing about the view in the senate and in the house, is that they now see trump as a political savant, someone whose true talent is responding to the base. but they say he is so limited in being able to actually assume the role of leader. charlie: he seems like he does not want to disappoint the base, rather than reaching up. -- reaching out. he clearly has a problem with women, yes? robert: in every poll he has a problem with women. charlie: why doesn't he speak with that? robert: he does not speak to it because he thinks at the end of the day he can win women voters. he is convinced he can win african-american voters and young voters. he called it is, quote, "aura of his personality." every poll shows he would be a historically bad comedy in terms -- nominee in terms of polling. since the washington post began polling, we've never seen a major figure closing in on the

nomination with these unfavorable numbers. charlie: is this simply a place for he decided -- robert: another stage? in some ways it is. every time i see trump he says, i don't know why am doing this. turley: why does he say that? robert: because it comes to your point, he doesn't need a presidency. charlie: his wife said, life is so good, why do you want to do this? explain to me what you think is going on with them. robert: we try to try to out and he talked up his internal monologue he has had with himself. i had spoken previous to this interview, at this stage in his life, he has accomplished a lot business. 69, 70 years old. he thinks public life, finally, is something he wants to do. he flirted with it in 1987, flirted with in 1999, 2011. finally he said, he told his wife this, you want people to take you seriously, you have to

get in the ring. he was becoming somewhat of a mock figure in american politics. for someone was criticizing the president, who was always moving towards a presidential bid but not doing it. he recognized that more than anyone. charlie: i think everyone wants to know what drives him. i talked to megyn kelly the weekend, having suffered a lot of tweets that made fun of her and criticized her. to the heart, some sense of her competence. i said, what do you want to know? she said why? , he launched a series of attacks against her as a reporter. has he attacked any other reporters? robert: he has attacked numerous reporters. he is relentless with reporters. charlie: he thinks the media is what? robert he thinks the media is : unfair to him. he thinks they are biased, not

against his politics against convention. he believes there is a conventional mice in the press and that precludes him as an outsider. charlie: is he simply not prepared, does he not have the temperament, the not have the understanding of the issues? as you pointed out, his suggestion of how he is going to make up a $9 trillion deficit -- robert: $19 trillion debt. he says he's going to a reset into presidential terms. that intothat-- erase presidential terms. it's impossible. charlie: what does he say? robert: when asked the question of why, when you talk to trump, at the bottom, the foundation of

what he is doing is a belief on trade going back to his experience in the 1970's. charlie: he has made that argument against china. robert: japan as well. his constant refrain has been traded. i think it has built over time. when you asked why he is doing what he is doing and how we can solve the national debt, when he says is i am going to get growth through trade. most economists say this is an unrealistic proposal, but at his gut he thinks trade and having better deals is going to solve the issue. charlie: does he have this confidence in his ability, or is it simply a mindset that he thinks plays well? robert: its an unerring confidence. charlie: everything is i'm the greatest, i will be the greatest everything. robert: very few people questioned him within his orbit on that. people not just in the campaign, his friends. he has such confidence about himself and his ability to change situations and to fix things, he does not like to hear criticism. charlie: he is also a product of the media. isn't he? he watches television all the time. he is never in a room where there is not a television on or does not have access to twitter.

robert: when i am in his office for an interview in trump tower, i've been in his boeing, constantly television. listening to television -- he reads constantly, too. every article about his campaign. he gets it printed out. doesn't use e-mail, doesn't use a computer. with a sharpie marker. when he likes and what he hates. this is great, i don't like this. he consumes media constantly. charlie: what's remarkable to me is the people who are supporting him, notwithstanding knowing his flaws. they have no apparent connection other than that they believe that he believes in them. robert: that is an important point. it is not always about trump. the trump supporters, i am in -- i have been covering them for 18 months.

they are people who believe institutions have failed them across the board, and not just the obama administration. republicans in congress, corporate america, wall street, they feel they have stagnant wages, is a portrait coming apart. white, working-class america that feels like they are disengaged from their own country. trump represents not someone who is just a celebrity and will be their champion, he is just different. they want something different. charlie: because everything else that has been tried in their definition has not worked. robert: we ask why are they supporting trump over cruz, they say trump will go around the whole system. that's what they want, wholesale change. charlie: they believe he will negotiate with the chinese for a better deal. robert: and he will put up an impenetrable border wall with mexico. charlie: it is an interesting idea. walls are going up in europe of one kind of another. walls are going up in terms of political campaigning here about what trump wants to do.

for me, it is a worrisome idea that we are walling ourselves in. robert: it you see it in europe with the rise of the hard right in response. there is a connective tissue. charlie: what is connective? robert: it is connective in the reaction to what is happening in global affairs and the global economy. i don't think it is as connected on the ideological front, because trump is a messy project on his views. he is hardline on his views. charlie: where is he not hard right? robert: he makes sure to reiterate on abortion. he is for exceptions. rape, interests, and the life of the mother. est, and the life of the mother. he is someone who does not champion those issues on the

campaign trail. charlie: but he did not call abortion murder, did he? robert: no. he is not really a social conservative at his core. charlie: does he see himself as reagan-like? robert: he sees himself as a grand leader. he sees himself as someone of reagan's stature. one of the first things he did when he was in iowa last year was hand out pictures of himself and reagan. charlie: is it your guess that he will not be the nominee? when donald trump gets the convention, conventional wisdom is he will not get the nomination. robert: yes, that is the conventional wisdom. charlie: do you agree with that #robert -- agree with that? robert: i agree with that to an extent. i kept asking, why haven't you built the relationships that will enable you to go to a second bout. ticket saying, i am into the fight.

when you go to the floor and you have alienated summary people, it could turn into a paul ryan or a mitt romney because the relationships are not there. charlie: would he support paul ryan? robert: probably not. he threatened to do a third-party bid. charlie: very late in the game to do that. robert: very late in the game to do that. his campaign says they will have an argument to make, if they are 30 delegates away, 50 delegates. it is, in effect, their nomination. charlie: do think he will destroy the republican party because they will be threatened at the house and the senate level? robert: he could create sweeping change in the house. how are they going to win? you look at trump's members -- numbers in the philadelphia suburbs. charlie: could he entertain the idea that he might destroy the republican party?

in other words, does he sit down and say, are they right, mi i perhaps notm good for this? robert: no, that is not his way. charlie: his way is to be overly confident. he did say he would select someone from washington, a washington insider. robert: if you want to go he was telling me he might do ben carson or some other outsider. charlie: back in a moment. ♪

♪ charlie: he has also served as deputy mayor for economic development and rebuilding under michael bloomberg. last year he cofounded sidewalk labs with google. the company develops technology. challengeogy which problems for big cities. they lost their first project earlier this year. payphones were replaced with kiosks, providing free wi-fi, phone calls and charging stations. welcome. dan: it is great to be here. charlie: talking broadly to me about the future of the city. dan: i am a complete optimist.

when you look back over the last couple hundred years we have had , three big technological revolutions that fundamentally transformed life in cities. the first was a steam engine, which brought people to cities more easily, industrialize them, made modern water systems possible. the second in the late 1800s was the introduction of the electric grid, which made them a vertical, made them easier to get around and lit them up. the third was the automobile. we had two separate roadways and accommodate parking. it made cities easier to get out of. we believe we are at the dawn of the fourth technological revolution in cities, and that is the digital network age. and it is really exciting because it is going to affect pretty much everything that takes place. charlie: how will it play itself out? dan: in lots of different ways. we are starting to see the beginnings of it and things like uber and airbnb.

if you look at the components, it is not just the sharing economy, that is a component of it, but if you think about the elements -- we are getting to the day or all of us are going to have smartphones, will all be connected by fiber. we have sensors, location services, cameras that are capable of understanding our environment in ways we never have before. we now have social networks that establish relationships with trust with people we do not know. advanced computing power, artificial intelligence, machine learning. the ability to display data and -- in new ways. technologies with robotics and other things are now making it possible to see almost everything in a city differently. uber would not have been possible five years ago, but we did not have advanced location services, the computing power.

we do not have these trust networks that enable you to get into a car with a driver. that is just the tip of the iceberg. cities have not really adopted them, but it is just starting . charlie: did this begin with you as that the mayor in terms of understanding, a, cities, b, you were an investment banker, and also responsibility with mike bloomberg for new york. and it's economic development as well. was that the beginning of you in taking a different and higher level of interest and concern and appreciation of the possibility? dan: certainly my interest in cities started with the effort to bring the olympics to new york. that became a plan for the physical future of new york, which led me to mike bloomberg. i spent six years as deputy mayor, and he asked me to help run the biggest technology company in new york city, bloomberg lp.

it is the combination of those experiences, as a urbanist, to run a city. someone who is running a technology company, then beginning to see the potential for technology to change our cities. you asked, what is an example. these things will not unfold right away. when the electric grid was first introduced in 1882, it took decades for a to be fully felt in cities and then around the country and around the world. but, let's take autonomous vehicles as an example. they are coming, there is absolutely no doubt. let's imagine a place where you have in a city only shared autonomous vehicles. what happens? the first thing is we will have much better congestion on the roads. it goes way beyond that. the average american uses his or her car only 3% of the time.

the average american's second biggest living expense is the automobile. about $9,000 a car including depreciation a year. what happens if the american doesn't own a car anymore, but they share them? to the city, you can basically get rid of 30% of the land dedicated to parking and a separate roadways, which enables you to rethink the use of land in cities, reclaim all that space for open space. or perhaps increase density. charlie: how did you find google? dan: they actually approached me. larry page has been very interested in cities, he really believes it is the next frontier, and we started talking. over time it morphed into what so far has been a fabulous partnership. i love being affiliated with google. charlie: is the partnership primarily sidewalk labs? dan: yes, it is the company we

created together. it is an alphabet company. charlie: google is one of the companies under alphabet, of which sidewalk labs is another. dan: sidewalk labs is a company whose mission is to use technology to solve big, urban problems. that is what we are in business to do. charlie: what kind of problems? dan: let me give you an example. one of our portfolio companies is doing in rip city you alluded to it in the beginning. one of the biggest problems we face, throughout the country and around the world, is digital inequality. in new york city alone, new york city has 8.5 million people. there are three million people who do not have access to broadband. that is a huge problem, because with this digital divide we are leaving more and more people

behind. it is fundamentally unfair. we worked with the diblasio administration. it started in the bloomberg administration. to work out a deal in which we are going to replace every single one of these 7500 payphones, and we are replacing them with these incredible structures. if you are on 3rd avenue or 8th avenue, you are seeing them pop up everywhere. they are iconic, sleek, in what -- and what they offer is free, superfast wi-fi. if you have wi-fi in your house, they are about 50 times faster than what you get in your house, absolutely free. there is also free voice calling, free video calling, free phone charging, public information. there is a button to access to 311 and 911. it is all right there.

that is, for us, a product which we think helps resolve a big urban problem. charlie: digital inequality. you make your investment back? dan: almost all of them have digital displays so we can sell advertising on them. the city gets 50% of the revenue. we believe the city, over the life of this contract, generate -- will generate up to $1 billion, which could be redeployed for other city priorities. charlie: who is your competition? dan: there are a lot of companies that focus on, " of aled "smart cities term i hate because i think cities are smart and great in general. ibm, cisco. there are a bunch. we are taking a pretty different approach to it. we like to take that space and -- that is in the middle between the big, sort of, heavy, enterprise organizations like

them, and the civic hackers, and operate in that space in between. what i have found is that one of the reasons that technology that has not been integrated, and there's a massive gulf that exist between the urbanists, people who plan cities, run cities. you know some of them. and the technologists. they do not understand each other, they literally are speaking two separate language s. what we are doing is putting together a team of urbanists and technologists. we step back and said, what is the future of cities? how is this technology going to fundamentally affect cities? when you actually play it out, you actually see a lot of different things which will, i think, create cities which are much greater, more efficient, more resilient, more adaptable, more personalized.

we really believe that as we see this revolution play out, we will be seeing very different cities that really improve the quality of life dramatically, and is the place we want to play. charlie: is this happening in cities around the world? dan: it is starting to. it is slow. look, it is complicated. cities have budgets, they have politicians, vested interests. nothing is easy, but i think we have demonstrated here in new york that we can get lots of things done here. what you are starting to see is many cities around the world really beginning to focus on it. here in the united states, chicago is really a leader. new york, los angeles, san francisco, boston, a number of others. in fact, one of the other things we are excited about is we have partnered with the united states department of transportation. they have issued a smart city

challenge to basically create a next-generation transportation and is a are going to award $50 million to a medium-sized u.s. city and give the money to them to build that next generation transportation system. we have partnered with the united states dot to build a core element of that, which we call flow, which will collect a data and analytics platform which will collect a lot of the ground information. charlie: that will go to whatever city is chosen? dan: that hopefully other cities around the world. think about a city where you have integrated data and true connectivity, then think of the impact on health care, education, public safety. i think we are going to see so much change because of our ability to understand what is

around us, take that data, and then apply it in ways that give us so much greater insight that enable us to prevent, enable us to anticipate, enable us to plan, enable us to really bring things together that we cannot see today. charlie: thank you for coming. dan: great to be here. charlie: back in a moment, stay with us. ♪

♪ charlie: arianna huffington is here. she's the editor in chief of the huffington post media group. she has also taken on a new role as a sleep evangelist. she has a new book that explores the causes and consequences of sleep deprivation. ariannaased to have huffington back at the table. county among your disciples, tell me among those who think you are onto something big. arianna: you have made napping legitimate, because long before i became a sleep evangelist, you were talking about how you had to choose between 20 minutes additional prep or 20 minutes of a nap, you would choose a nap

because that would make it easier for you to retrieve all the information you had to be fully present during the interview, and this was much -- and all of these were much more important than getting one more fact. charlie: at every level of what you argue, whether it is sex, work performance, the way you feel, or whether it is your health, i believe that sleep is crucial. i think seven hours is a great place to go. i generally get about six, then make it up with a couple short naps. end up with seven. but it makes me feel better at every moment of the day, and a sneak want to be more energetic. it makes me feel that i am on the top of my game. arianna: exactly, it is a huge performance enhancer and that is what is ironic. how come we came to see it as the opposite? in the history chapter, i went back to trace the moment when we began to scorn and devalue sleep.

it was during the first industrial revolution when we began to think that human beings will be treated like machines, and you could actually minimize downtime. then of course you had thomas edison, who openly scorned sleep and called it an absurdity and predicted there were be a time when sleep would be a limited. -- eliminated. charlie: sleep two hours, work two hours, sleep two hours. arianna: he actually really believed that. there was a revered cultural icon who also begin to change the way we perceive sleep. then came the third revolution, the digital resolution, when we became addicted to our smartphones. people have a hard time disconnecting from their devices and turning off the lights. 60% of people around the lights -- around the world have slept with phones in their hands. charlie: because they were sleep deprived. margaret thatcher is part of the game as well because she said,

i only need four hours, i am a superhuman. charlie: but she also naps every day religiously. nobody could disturb her. arianna: going back to sex, the research now is amazing, about erectile dysfunction and sleep deprivation. lowered sperm-- count, and even studies that show if you are fully recharged and have had a full night sleep, you are 14% more likely to have sex. [laughter] charlie: what does the science teach us? arianna: this is the golden age of sleep science, and it is very recent. the first scientific sleep

center was founded at stanford in 1970, 44 years ago. basically, every day, literally, we have new evidence between a connection between sleep and every aspect of our health. from obesity and diabetes to hypertension, heart disease, cancer. every aspect of our emotional intelligence and moon. .ou know, -- mood you know how we feel about our , lives, how depressed or anxious or fearful we are. then, our actual cognitive functions. it came to me after writing the book, but there was a piece of the harvard business review, by the global learning officer, and by someone else described as a mackenzie sleep specialist. the headline was the proven link

between sleep and leadership. and they actually took us to the -- through the science of what happens to the prefrontal cortex, where the executive functions are housed. when you're sleep deprived, everything is degraded, every aspect of leadership, decision-making, team making. everything is degraded. this whole collective delusion that we will sleep when we are dead -- charlie: i will catch up later. arianna: ceos often congratulate their employees for working 24/7. this is the equivalent of congratulating someone to coming to work drunk or smoking everyday. charlie: it is interesting that we have somehow developed, in part, this idea that those people who do not get much sleep are superhuman and overachievers, and they are the best you can be because they

pound more time into their functions. arianna: right. but this is part of the delusion that looks at work in terms of time you put in, as opposed to energy you put in, and the quality of your mental clarity, your creativity that you put in. charlie: when did you start this journey to becoming a sleep evangelist? arianna: i started the journey the hard way, when i collapsed from sleep deprivation. broke my cheekbone on the way down. charlie: you fell asleep, or what? arianna: no, i was simply exhausted. i literally stood up to get a sweater and i fainted. it happened to hillary clinton, you know, when she collapsed, hers was worse. she hit her head and got a brain clot. it happened to multiple executives. it happened to the ceo of united. sleep deprivation is the key.

when you are sleep deprived, all the new science shows that the stress hormone cortisol increases in your body. therefore, stress, as you know, is at the heart of practically every disease. also, all the factors that have to do with our immune system go down. charlie: you are less able to be resistant to whatever might wish to harm. arianna: exactly. all the factors that have to do with inflammation go up, all the hormones go up. charlie: do you think that people have finally gotten it because of you and others? arianna: i think we are at this amazing turning point where everything is coexisting. like, you have executives who are still living in a neanderthal way of living where the more hours you spend on the job the better you are going to be.

but you also have that the entire hotel industry, for example, now competing with each other. which hotel chain is going to be the chain that offers the best sleep? which is a really the most important thing you need. charlie: you are seeing companies thinking about providing sleep rooms? arianna: absolutely. at the huffington post we are a pioneer of that. we have nap rooms. we are opening a third. more and more companies are opening nap rooms. it is also, there are some ground rules like recognizing once you finish work you should not be expected to be on the e-mail. if it is important, we will call and text. it is part of that. charlie: i know people that every night of their life take sleeping pills. not good. arianna: the evidence is

overwhelming that sleeping pills are connected to greater incidence of all these diseases, including alzheimer's. is one thing to take a sleeping pill occasionally, if you are jetlagged, had a genetic -- traumatic experience, but sleeping pills were never intended to be a nightly occurrence. charlie, if there is one simple thing that people can do tonight to change their sleep, it would be creating a transition to sleep. charlie: how do they do that? arianna: first of all, what we do now is we are on our smartphones to the last moment before we turn off the light. there is no line between our -- we need to slide into sleep. 30 minutes before i turn off the lights. charlie: what you do in a 30 minutes? arianna: first of all, i turn off all my devices and gently

escort them out of my bedroom. [laughter] arianna: i promise you, they are there any morning. then i have a hot bath, which is like washing the day away. if you prefer a shower, you have a shower. but there's something wonderful about the water. it is like, this is it, there is nothing more i can do about my to do list, my completions, this is the end of the day. time to get recharged. i used to sleep literally in my gym clothes. charlie: you didn't. not literally the ones i wore that day. now i have beautiful lingerie. or sleep naked. something different. charlie: this is sleep. arianna: this is sleep. because otherwise, i've talked to hundreds of scientists and it will tell you your brain will get conflicting messages. are you going to the gym or are you going to bed?

then, i only read real books in bed. charlie: nonfiction? arianna: physical books. i do not read on my ipad. the blue light is terrible for activating your brain. i've read books that have nothing to do with work. i do not read about politics, i do not read about economics or the media. i read philosophy. i read poetry, i read novels. i read things that take me out of my daily life. charlie: how is your life changed? obviously, more sex. arianna: definitely. [laughter] charlie: your performance and every aspect of your life is better. you feel better. you are more resistant to disease. arianna: yes. i haven't had cold the way i had. when i was sleep deprived i was , perpetually getting colds. the other thing is i bring more joy to everything i am doing.

right now, when i look back in , iat my sleep deprived self do not like that person. i was more irritable and cranky. i even like you when you were irritable and cranky. [laughter] arianna: the slightest thing upsets you. charlie: i have never been irritable and cranky. arianna: that is because of your naps. [laughter] charlie: let's talk about sleep disorders. arianna: sleep apnea is a major one. sleep apnea is at the heart of a lot of major problems with sleep and often it is under diagnosed. the danger is that your sleep is never recharging enough. you never go deep enough, you never go into rem sleep, the really recharging sleep. as a result, you are always

exhausted and therefore all the other consequences are more likely to be diabetic, more likely to have hypertension, come up. also, it is a huge problem when when it -- when it comes to drowsy driving. charlie: you are affecting not only your life but others. arianna: exactly. this is been a silent epidemic because we are dealing with drunk driving, in the numbers -- in terms of awareness. the numbers have been going down. the numbers of drowsy driving have been going up. last year we had 1,200,000 crashes because of drowsy driving. it can happen in microseconds of micro sleep. we are launching a campaign with uber against drowsy driving. because now, the great news is because of all these ride sharing technologies -- we are doing multiple things.

we have a petition with change.org that you can sign the as they slid the same as a designated driver campaign. it says i will not drive drowsy and not let my friends drive drowsy. ac -- against the mc machismo thing, yeah, i am tired but i will power through it. i'm going to have a coffee or a coke in power through it. i'm going to ride along with uber drivers and people can request me. charlie: sleeping with other people. arianna: big problem. it should be avoided at all costs. [laughter] charlie: true. arianna: but seriously, i am greek and there's a big difference in europe. in case you thought my accent was from arizona.

charlie: i did. i thought southwestern, for sure. [laughter] arianna: if you don't always sleep with someone, if they snore, it means you do not love them. it means you will not have sex. the european attitude is very different. charlie: what is that? it is basically, if either one of you snores and the other one can't sleep, it is better to sleep apart. you can have sex and that separate, it doesn't preclude -- you do not have to be in the same bed the whole night. what happens is you wake up exhausted and irritable. it is worse for the relationship. charlie: how about things like trying to make up for sleep. you have only got four hours last night, tonight i will sleep 10. arianna: that is better than not doing it, but you cannot make up for sleep. one of the best things is just to look at our lives in terms of recovery time.

we camped in aspen, we had this great session. charlie: thanks to you. arianna: the golden state warriors. he was amazing. he talked about how getting eight hours of sleep dramatically changed his game. lebron, kobe bryant. what has happened with andre is he has actually document to -- documented this. he showed to all of these ceos the direct impact on his performance. his fouls going down by 45%. all the specific numbers. charlie: what is a foul? arianna: you want me to give you a lecture? you took me to a basketball game and you had to explain everything to me. i don't know anything more. [laughter] arianna: he doesn't foul as much. it is all data, it is all in the book of how his game improved. it was impressive to see all of

these ceos there that thought somehow in order to continue to be successful in achieving, they had to sacrifice sleep. to look at a major athlete who valued his sleep. charlie: it was essential. arianna: because it was essential for his performance. someone else you interviewed, roger federer, he talks about how essential his sleep is before game day to the point when before wimbledon, he has a separate house for himself and a separate house for his family. his sleep is not going to get disturbed. charlie: he goes home and goes to bed. arianna: he has a separate bedroom. charlie: you have a successful company, you write books. "thrive," and "the revolution." revolution."

anything missing? do have great ambitions that are unfulfilled? arianna: no, i feel very blessed. charlie: you look great, you are ageless. arianna: i have two daughters whom you know very well. my oldest daughter just lost a a series called "talk to me." charlie: it is kids talking to their parents. it is one of the important things i regret, which is that i never spent time to talk to my parents that much and record it. because my father was a fabulous talker, with a first-rate mind and a first-rate memory. we talked occasionally about coming back from the war, we talked about my performance in sports. but i do not talk enough to him, and this is a great idea. kids interviewing parents. arianna: exactly. for example, we gave the ceo of uber interviewing his dad.

it is incredibly moving. we just showed sam branson interviewing his father richard branson. what christina said is that normally when children talk to their parents, they talk about themselves. she wanted to turn the tables on them. then create a structure where hundreds of thousands of people around the world can actually interview their parents. charlie: it is a great idea. as important as the sleep revolution. thank you for coming. it was great to see you. you were as wonderful as always. thank you for joining us. see you next time. ♪
