people were talking about the "anchor man" movie. they are recutting it and adding more jokes. so 763 new jokes added to this movie that's already been released. we'll see. thank you. we'll be back at the top of the hour with live news. see you then. ever wonder what it would be like to go inside your own brain? a neuroscientist did just that. what he found was pretty surprising to say the least. >> in a pet scan, james spent hundreds of hours pouring over the brains of psychopaths. >> this is a comparison of this brain to a normal person's brain. >> reporter: over and over, the same thing. >> they all had an underlying path of loss of activity. >> reporter: a lot of activity that controls behavior and

motivation. >> both are turned out in these psychopaths. and the area that controls impulsivity and also the sense of morality and goodness and beauty is turned off. >> reporter: but then as he began another study on alzheimer's, he came across something strange. >> my colleagues brought in a normal group for alzheimer's and i was going through and comparing them. and everything looked quite normal. and then what happened is i came to one and it looked like this was all the murders look like this. that was the first moment i went, oh, that's curious. when i peeled it back, it was my name on it. >> reporter: his own name. now brain patterns alone don't mean you're a psychopath. there are other factors like genetics. >> 30 or so genes are associated

with that. it doesn't mean you're a psychopath, but it probably means you have traits like aggression. >> reporter: wouldn't you know it, fallon is distant cousins with the ax murder liz by boarden who was thought to have killed her parents. >> i had inherited really all these high risk genes. when it came together, i still didn't kind of care. it was kind of still a joke because i'm not a killer or a rapist or a psychopath. >> so why not? >> i was sitting in the backyard and my mother was pruning plants. and i was looking at her. she was sitting on this wooden stool. thr three-legged stool. i was just musing out there and i go, oh, my god, it's got to be it. it's her. she's the third leg of the stool. the first was the genetics. the second was the brain pattern, whatever happened. the third is why i haven't

turned out to be a psychopath had to do with the nurturing i got. i went back and looked at the pictures growing up and all these memories and movies and everything. i was treated so well. >> james wrote about his voyage in the book. it's fascinating. it's called "the psychopath inside." am i safe being this close to you? >> six feet is pretty good. >> psychopath has this pa jortive meaning. a lot of things that you wrote about in the book, what is a psychopath? given the context that you know about what's happening in your own brain. >> if you think of the different factors involved, it's like the olympic circles, the five rings. so there's five factors. if you have enough of these, at some point you're categorically called a psychopath, but you could be a borderline or only partially have psychopathic

traits. it has to do with how you interact with people. not just knowing. psychopaths know what you're thinking and feeling, but they don't feel it. and also your lifestyle. there's a whole part called anti-social personality disorder. that's a part associated with criminality. many psychopaths have no criminality whatsoever. they have the other stuff. >> you found out this information about yourself looking at the studies and putting it all together. did it make sense to you when you realized that you fit the criteria? >> i laughed it off because i went, i'm not a killer, i'm not a rapist, i'm not a psychopath. when i explained what the scans were to my wife, it says it doesn't surprise me. >> really? >> and then when i talked to a lot of psychiatrists who know me well for many years, they knew. they said we have been telling you this for years. i said, i thought you said you

were crazy. they all went through my lifetime and spent a couple years looking at that. i just never saw it. >> can you give me example? you obviously didn't kill anybody. >> i'm extremely manipulative. but i do it because i've been successful. i grew up in a loving family. i always got what i wanted. i never had to lie, cheat, steal, any of that. it came easily. but the core thing is i manipulate people all the time. i'm always on the make to create a world that you're going to believe in. but it's important for me to tell the truth. that's part of it. so the lying part, which a lot of psychopaths do, to me are cheap tricks. if you get everything you want, resort to manipulating people with the truth and other things. >> when you learned this about yourself, how did it affect you? you laughed it off initially, but as you pondered it and thought about it more and more, do you change? you're an adult and can't change

the hard wiring of your brain. are you more aware of those behaviors? >> i'm aware of them. after i knew the biology, the brain pattern, the genetics were there and the testing showed me as a borderline psychopath. not a full blown. and the people who knew me, the psychiatrists and people close to me, it was all confirmed. i didn't care. i just didn't care. it didn't register. i said that's the point. i think intellectually, enough narcissism. i started to do things the past year and a half, two years to see if i could overcome this. just by stopping every time i interacted with somebody. because my natural tendency is to do the most selfish thing. >> everyone should read this book. you learn about the science, but it's a fascinating read as well. thank you for joining us. next up, the power of a

single word. hello. it's a campaign that i launched with oprah. but next, we have a fascinating story we found from the sochi olympics. it really made the difference between a morning around the house and getting a little exercise. hi-ya! and i tried a baking class. one weekend can make all the difference. unlike the bargain brand, depend gives you the confidence of new fit-flex® protection. it's a smooth and comfortable fit with more lycra strands. it's our best protection. take your weekend on with a free sample at depend.com ameriprise asked people a simple question: can you keep your lifestyle in retirement? i don't want to think about the alternative. i don't even know how to answer that. i mean, no one knows how long their money is going to last. i try not to worry, but you worry. what happens when your paychecks stop? because everyone has retirement questions. ameriprise created the exclusive confident retirement approach.

as i have been watching the olympics, i have been thinking about what goes into making a champion. curious about this. one event that really grabbed me

this week was the women's bobsled competition. the u.s. teams won silver and bronze. one of the silver medalist lauren williams started pushing a sled just six months ago. and the thing is the rest of the team is a lot like her. >> reporter: lauren williams is a sprinter with medals on the track. she was recruited for team usa in bobsled by lolo jones, who first made a splash as an olympic hurdler. she took up bobsled just two years ago. there's a college softball star and five from the track including williams and jones. two women with nfl players in the family, bronze medalist, her brother is a defensive tackle with the vikings. her father and cousin were major league baseball players. >> you saw six women. none of them took up the sport

until their mid-20s. yet here they are. what does that tell us? what does it say about athletic talent being genetic or really environmental and learned? >> it tells us that in certain spor sports, there's quite a bit of skill transfer. you look at the pusher, lauren williams, who was retired from track. she was a 2005 world champion in the 100 meters. now she's one of the best pushers in the world having just started bobsled. she has a large proportion of fast twitch muscle fibers. you can alter them to a degree, but can't -- even as they got way stronger, they didn't get faster. the conclusion was you need to get those people with the fast twitch muscle fibers in the sport in the first place. >> one thing you do in the book is blow up the idea of the 10,000-hour rule. the idea that it takes 10,000 hours of intense practice to

reach an elite level of sport. we hear about these skiers and skaters who are starting so young. that's what i pay attention to as a dad. if it's not 10,000 hours, is there a magic number? what do you tell parents? >> there is no magic number. that 10,000 hours came from a tiny study of violinists. even there 10,000 was just an average. and the range was incredible. so there is no magical number. and actually the science coming out of most sports is that the normal path to e elite status, elites practice less as children. they have a sampling period through about age 12 while they find the sport that's right for them and focus in later. tiger woods is the exception. the rule is steve nash, who wanted to be a soccer player until 12. didn't get his first basketball until 13. goes on to become one of the best point guards of all time. >> i think there's a message

there for parents. i think about these issues more and more as a parent. now i transfer a lot of these things on to my own kids. david, thank you so much for joining us. >> thank you. still ahead, how to talk about sex to your kids. i have three daughters. i think about this quite a bit. but first the top five foods for your heart. ♪ aflac, aflac, aflac! ♪ [ both sigh ] ♪ ugh! ♪ you told me he was good, dude. yeah he stinks at golf. but he was great at getting my claim paid fast. how fast? mine got paid in 4 days. wow. that's awesome. is that legal? big fat no.

it's a little bit of information when you're talking about things you on the news. you're always talking about sex and sexuality. reproductive technology, which is a fun one to do these days. they only meet one way. we have to give ourselves a

little more credit as parents to come to terms with the fact that we're doing this all of the time. it may not be one way our parents did it, but chances are we may the not remember that any way. >> we know our kids best, but our kids are getting information in a the lot of different ways. one of the things you talk about in the book is teens spend an average of 7 hours a day in front of a screen. why is that important. >> it's important to know what your kids are watching and what their friends and peers are talking about. we need to be involved in this and use our media in a smart way. it's an awesome tool for us to initiative these conversations about sex and sexuality. it's much harder to say, so, have you and your friends ever experienced oral sex before? if there's a study or something on the news or a conversation or show thinkey are watching, it's great jumping off point.

>> there are some hot button issues that surround this. you're going to have the talk, as we say. but there's lots of other social issues that come up. our kids are all pretty young still. how do you decide the right time? does it come up organically? >> sometimes organically. my son when he was 4 asked questions about where babies came from and how we talked about sperm and egg and 5 he was talking about how sperm and egg typically meet. i gave him the honest, simple answers and said love the fact you're ready to have this conversation. if you have anymore questions, ask me. at the end of the conversation, the only other question he had was when you were a little girl, did your mom answer all of your questions? i think that's always been a lesson for us. we're afraid we're going to tell too early. they just want to know if they have a question, they can come to us and we'll give them the truthful answer. >> dads and daughters, moms and sons. >> yes, absolutely. always be talking to our

children, no matter what the gender of that child is. and i will say i know you have girls. the father/daughter relationship is so important. i say that not just as a professional, but also in my own personal life. you really shape how girls see themselves and how they communicate in relationships and how they should be treated by partners and friends no matter what gender that person is. it's an important role. >> it gives me goose pumps and puts the pressure on, but in a good way. congratulations on the book. oprah and i are going to share something we have been thinking about. a solution to a big problem. an epidemic that kills more people than obesity. stay with us. coach calls her a team player. she's kind of special. she makes the whole team better. he's the kind of player that puts the puck, horsehide, bullet. right where it needs to be. coach calls it logistics. he's a great passer. dependable. a winning team has to have one.

when was the last time you said hello to a stranger passing you on the street or a friend you hadn't seen in years? >> hi. >> hi. >> how you doing? >> hello. >> hello there. >> those are just a few of the stars who signed up to try to help battle america's epidemic of loneliness. it was started this week by myself and oprah. 60 million americans report feeling lonely. it's 1 in 5. you could be one of them and not even know it. it's not just in your head. it's an epidemic that affects your health in many ways. >> the bottom line says people with strong ties to family, friends or co-workers have a 50% greater chance of outliving those with fewer social

connections. an extraordinary statistic. >> we used to believe it was simply because if you had friends, they were more likely to check in on you. encourage you to take care of your health. it seems to be more than that. people who are lonely or perceive themselves to be lonely, perceive social isolatio isolations, they have changes in the body, both within the brain and body, the brain perceives threats that aren't there, they live with high stress levels all the time. they don't sleep as well. >> is it an emotional pain or is it also a medically diagnosable physical pain? >> it's a physical pain as well. let me be precise. the areas of the brain that are responsible for physical pain, those are the same areas of the brain that will light up in someone who has chronic loneliness. they feel physical pain by all intents and purposes. lonely, by itself, more than obesity, more than air pollution, leads to early death.

>> this campaign opened just say held e low, you're using your star power to get the biggest names. what is the key point of this campaign? >> what i realized is that everybody is looking for the same thing. no matter if it's politicians, senators, presidents, beyonce, we're all looking to know, did you see me? and what i said mean anything to you? just saying hello is a way of validating even a stranger. >> what i also found fascinating as i looked into the the studies about loneliness is how taboo this topic is. people would rather say they are depressed than say they are lone lonely. today make a pact to change that. all it takes is one word, hello. call your aunt that you haven't spoken to in months or an old friend. say hi to them. say hello to the person you sit
