absolutely. i was born in michigan, but my parents were born and grew up in india. and like a lot of immigrants, they thought they would never be able to learn their whole family history. that was lost, they thought, in the old country. but i always wondered, and so i gave professor gates the names of my immediate relatives along with a cheek swab of my dna. here's some of what he found. >> to dig even deeper, we sent sanjay's cousin to hardwar, located on the ganjy river. it's a place of tremendous jean logical importance to hindus. they come here to consult with priests. the male lineages on their family trees. we arranged for him to meet with two priests who have devoted their lives to writing down family history. we're hoping that we'll discover other details about sanjay's extended family hidden in the cryptically encoded scrolls. >> it's all written down? >> that's your family history, my brother. >> amazing thing. i have to go. >> oh, you have to go. >> have to go see this. >> the scrolls contain information going back incredibly eight generations on sanjay's father's line. cousins, grandparents, grade grandparents and beyond. they're all here. a symbolic gathering of generations of ancestors. family members that sanjay never even knew he had. >> an incredible experience. you can see the rest of the story, finding your roots, sunday at 8:00 on most pbs stations. being a part was incredible, and when professor gates was here in atlanta, we had a chance to sit down and talk more about what it all means. >> one of the things that comes out of this and you and i have done today was had this long n conversation about my family, my ancestry. i had the privilege of having you help me give me astonishing information. >> i was moved for you. at one point, i had tears in my eyes that your family records would be kept by a cast of priests and inscribed in code, and they're assigned to your family. we talked to some jeanologists, and they said, forget it, indians, what do we know? they don't care about jeangeneo? what is your favorite subject? of every human being all across the world, no matter what the color, is all about themselves. and that's all about yourself. >> your name has become synonymous with people tracing their roots and finding out about their ancestry. i'm curious, have you done this? >> my father looked like a white man and my grandfather was so white, we called him kaspar behind his back. so we wanted to know, we knew why the gates' were a family, but where this white man came from. and we know he fathered jane gates. she had five children and she wouldn't tell them the identity of their father. she only told them that they had the same father. so one of my motivations for doing the pbs series was to use genetics to find out more about myself. and we found out two very interesting things. first off, we found out that my ad mixture, percentage of anc t ancestry from europe and africa and asia or native america over the last 500 years. and mine revealed in the middle of the shoot for the first series that i'm 50% white and 50% black. the director of the voice institute for african-american institute at harvard is a white man with an identity crisis for me. the other thing was that white man was definitely irish. >> if you could go back and visit perhaps anybody in your book or books or just in history, somebody you would really like to see that you never had a chance to meet? >> my great, great grand father. i would like to see him in the company of my great, great grandmother to see if they had an equal relationship, if it was a relationship no matter how odd it might strike us, that was based on love? a fact that she told her children that he fathered all of her children, all of their siblings, suggests some sort of attachment. in 1865, she is a slave, in 1870, she pays $1200 cash for a house in a predominantly white neighborhood. that came from him. i would like to know about my irish roots. >> it would be pretty amazing to be able to do that, to go back and see who your ancestors wurb. >> yeah. and also understand what it means for my identity as an american and affkrn american to be of equal proportions anglo irish and subsaharan african. i know a lotun about africa. i'm a professor of african studies. my great mentor introduced me to religion and knowledge. i love africa, but i also want to know, i wasn't conscious of having a white identity or an irish identity growing up. i would be interested in growing up. i mean, i like guinness. >> that explains that. >> we could see the pretty irish girls. i grew up in an italiitalian ir paper mill town. so all of the girls i liked were at the catholic church. we would go there. >> guinness peer, is that your favorite beer? >> the black man's beer. >> is that the beer you had at the summit? >> indian beer. >> got some suggestions now, if you watch something like this and you're interested in finding your roots, talk to your family, get specific names, grandparents, great aunts, as many as ucan find. you can also get a lot of information for free online. birth certificates and the like, and if you want a detailed family tree, you might hire a trained jeanologist. it's not cheap. you're probably looking at $1,0$1 tho $1,000 at least. a more complicated search would be more. another approach, an interesting one, is simply testing your own dna. it's not to find relatives, but you can learn about your real ethnic background. what part of the world your distant ancestors came from. it starts at about $200. a remarkable experience for me. coming um, 80% of women have it. 100% of women hate it. we're talking about cellulite and the first fda approved lo long-term treatment. i'm going to show you. [ rosa ] i'm rosa and i quit smoking with chantix. when the doctor told me that i could smoke for the first week... i'm like...yeah, ok... little did i know that one week later i wasn't smoking. [ male announcer ] along with support, chantix is proven to help people quit smoking. it reduces the urge to smoke. some people had changes in behavior, thinking or mood, hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. if you notice any of these stop taking chantix and call your doctor right away. tell your doctor about any history of depression or other mental health problems, which could get worse while taking chantix. don't take chantix if you've had a serious allergic or skin reaction to it. if you develop these stop taking chantix and see your doctor right away as some can be life-threatening. if you have a history of heart or blood vessel problems, tell your doctor if you have new or worse symptoms. get medical help right away if you have symptoms of a heart attack. use caution when driving or operating machinery. common side effects include nausea, trouble sleeping and unusual dreams. it helps to have people around you... they say, you're much bigger than this. and you are. [ male announcer ] ask your doctor if chantix is right for you. and then treats day after day... well, shoot, that's like checking on your burgers after they're burnt! [ male announcer ] treat your frequent heartburn by blocking the acid with prilosec otc. and don't get heartburn in the first place! [ male announcer ] one pill a day. 24 hours. zero heartburn. under the microscope. two different treatments to combat cellulite were approved by the fd ark. the first is on the market. i want to warn you, you're about to see graphic images of surgery. >> these are actually areas of fat that are protruding through the skin. >> cellulite. more than 80% of women develop it. and they spend millions of dollars on over the counter creams as a tempry fix. >> i have been working out my entire life. very athletic. have been forever. used to be in the military. i still have issues. >> so she chose to get cellulase. it targets secellulite. >> there are fibers under the skin pulling the skin down. we're going to release the fibers. >> according to a small peer review of ten women, with just one treatment, it's gone, and the results last a year or more. the patient uses just a local n anesthetic and is awake the entire time. >> you feel little needle there. >> once numb, a laser is inserted right under the skin. >> right this moment, i am melting the fat that is causing the bulges up in her skin. so remember, it has two things, it has bulges and dimples. and that's that cottage cheese appearance everyone complains about. what i'm first doing is melting the bulges. all right, so we have done all of our green circled areas. now we're going to go after these -- those things that are pulling down the skin. >> here's what it looks like from the inside. first, the laser goes in. and melts the fat cells that cause bulges. next, it cuts and vaporizes the fibers under the skin which cause the dimples. then it heats the skin, which the company says allows new collagen to form. >> this is not something that happens overnight. you know, it's a dynamic process. i mean, and we get people who want the quick fix, and we can't deliver that. >> it can take about three months after the procedure to see the full results, but it's too soon to say just how long these ruts will last. also, it's a cosmetic procedure. so not covered by insurance, and it's quite expensive. $2,500 for a single area on both legs. we also talked to several doctors who were not affiliated with the study and they said the biggest riv is a possible insfekz. it's important to work with a doctor that is experienced with the procedure. you want to consider this or anything cosmetic, best advice, weigh the pros, the cons, do it with your own doctor. >> one of new york city's bravest, a firefighter and self proclaimed fitness junky. struck by a bus and nearly killed. now he's on a bike as well. how many times have you gone about your day and bam, a great idea pops into your head. for most of us, there next thought is that's next going to happen, but that's where a start-up called quirky comes in. >> it's human nature to invent. it's human nature trootie to make your life better. it's human nature to try to make the world around you a better place. and what stops people is to do that, and to execute on all those ideas. it's really hard. good ideas shouldn't find their ways on to shelves because they're the ideas of people without the right circumstances. they should find their way onto she shelves because they're great ideas, plain and simple. at aviva, we do things differently. we're bringing humanity back to life insurance. that's why only aviva rewards you with savings for getting a check-up. it's our wellness for life program, with online access to mayo clinic. see the difference at avivausa.com. back in 2005, matt was a new york city firefighter and an accomplished athlete. he was training to run the boston marathon. in the blink of an eye, it all changed for him. he was lyriding his bike up thi avenue when he was struck by a bus. the road back was long. december 2005, new york city is in the middle of a mass transit strike. new york city public transportation is shut down. matt long has no choice. he must hop on his bike to get across the city to the fire academy. so this wasn't just training. you needed to get somewhere? >> i needed to get to work. and i made it four blocks. >> four blocks. and then disaster. do you remember being hit? >> yeah, i remember putting my left arm up and just going under, and that's it. >> a bus that had crossed multiple lanes of traffic made a right turn, and in the process, ran directly into matt long. >> he didn't see me, didn't know i was there, whatever, and took me right under the front wheel. >> in an instant, the self- self-described fitness junky has gone from dominating race courses to barely surviving. >> every compound fracture, my right side, my pelvis was shattered and open as well, and the worst part is the bike and i became one, it severed my abdominal wall, my femoral artery, i was bleeding out. >> he stayed in the hospital for six months and ended with 40 operations. he had survived physically, but mentally, he was battling nearly crippling depression. >> at the table at the doctor's appointment, i said, i'm glad you paid for me to live, but i wish you had prayed for me to die because i can't do this. >> learning to live in his new body became his biggest challenge. >> i didn't think about what i couldn't have, how i could no longer run. i just said, i will. i will get back on a bike, get back on the course, and live the best i can. >> now retired, he coaches and regularly shared his story to motivate others to transform themselves. it gets even better. after recovering, he created the "i will" foundation to help other athletes, and in case you're curious, he's back to racing. he's got several races lined up and his dream of doing the boston marathon is bigger thou. >> how to beat the system when it comes to the best food for less. so who ordered the cereal that can help lower cholesterol and who ordered the yummy cereal?

[ male announcer ] one pill a day. 24 hours. zero heartburn. my next guest says our food system is broken. it's in fact endangering what is most precious to us. our environment, our health, and our future. pretty strong words, but the question is, how do we fix it. the author of "fair food," growing a healthy system for all. what is a fair food system? >> when i think about a fair food system, a system that is producing food that is healthy, good for our bodies, green or grown in a way that is healthy for the environment. fair means nobody in the system is getting exploited so everyone gets a piece of the economic pie. and affordable. everybody has access to that healthy food. >> healthy, fair, green, and affordable. >> is there some body or some thing that is wearing a black hat, is somebody doing something wrong to make it unfair? >> i don't believe it's somebody's blame the way the system is now. we have a food system in place today that i believe is broken in many different ways, but it's largely based on decades and decades of public policy has that driven the system in this direction. when most policies were put in place, they were put in place for good reason. it's just our context has changed. for example, when we first started putting federal subsidies in place to subsidize the production of corn, wheat, soybeans, we needed a lot of cheap calories to feed a growing population. now we're in a situation where we have an obesity epidemic. we need to shift to take care of the current context that we find ourselves in. >> subsidies allow some of the foods to be cheap. and if you're somebody who doesn't have lot of money, you want to buy as many calories as you can for as little money as possible. if you make it more equitable, does it make some of the foods more expensive? will it be harder for people to get the calories at the same price? >> we've got -- what i think about is what it's going to take to help create affordability for those foods that we know are healthier to heat. we know most of us need to be eating more fruits and vegetables, especially low income families. we have this program happening in michigan, talk about a solution, called double up food bucks where. where we're incentivizing folks to bring their dollars to farmers markets and buy fruits and vegetables, and it's not preventing them from getting the energy dense and caloric foods they need. >> if people are watching and saying i don't liver in a food desert, but i have a hard time getting healthy food for myself and my kids. it's not easy and it's more expensive than i like. what would you tell them right now, leevaving behind a larger message, what would you do? >> i would tell them there's nothing more important for your health. there's nothing more important to creating greater health than eating the right foods. so that, you know, we'll spend money on lots of stuff in certi society that we think are necessities. my believe is the first necessity is a healthy diet. there are ways to get a healthy diet, to buy the healthy food you need, and not spend an incredibly large amount of money. >> not break the bank? >> not at all. there's a myth that when you purchase food at a farmer's market it's going to be more expencive than a supermarbt. i say it's a myth because research has been done looking at prices of fruits and vegetables, comparing it to supermarckets in the same area, and the prices are comparable or less at the farmer's market. my belief is that don't believe the myths. get out there and spend some effort to find the foods you need to keep your family healthy. >> and supporting your local farmers as well. we have a little vegetable garden outside of our kitchen. i have three kids, 6, 4, and 2. and we grow things like tomatoes. what is amazing to me is other kids will come over, and it's literally a magic trick. they see these tomatoes and they're like, it comes out of the ground? my kids eat healthy. it wasn't because we preach to them, but they have access to it. they grow their own. >> and they taste the tomatoes and carrots from the garden and know they're going to taste great. >> we're really interested in this. it's something we're going to stay on top of. the book is fantastic. >> great to be here with you. thank you. >> you know, we're chasing life today in the produce aisle. pest side pesticides, they have been linked to disorders, even cancer. good organic produce is hard to find and sometimes expensive. when is it worth the effort? here is my grocery list. produce like apples, celery, strawberries, they typically have the most chemical residue. i think to buy them organic. onions, corn, avocado, those are going to be safer. so i might save a little more money and buy the conventional version. and easy rule of thumb to follow is if you're going to eat the skin, go organic. that's where a lot of residue
