least 18 innings on the same day. i'll see you back here at the top of the hour, 8:00 eastern time. first "sanjay gupta m.d." brings right now. >> hey there, thanks for joining us. good news this week about sunscreen. turns out it does more than prevents burns and cancers. the pictures we're about to show you are something you're never going to forget. i'll tell you exactly what you need to know. also, my friend dr. phil mcgraw is stopping by to get rid of the toxic people in your life. and how to negotiate win-win solutions with your friends, family, and the people you work with. first a crackdown on drug cheats in baseball. start out by asking this question. what makes these players so different from the rest of us? espn reported this week that major league baseball is laying the ground work to suspend some 20 players like major stars like

the yankees' alex rodriguez, and another former mvp ryan braun. players used a miami clinic that provided drugs which baseball bans as performance enhancers, testosterone and human growth hormone. major league baseball calls it an active investigation. rodriguez says it's not the time to comment. braun seays he's done talking. in the past, he's denied using performance enhancers, and rodriguez says he's been clean for a decade. joining me is dr. don catlin, an anti-doping scientist and one of the founders of modern drug testing in sports. >> thanks for having me. >> we've been hearing a lot about this. baseded on reports, the players were getting testosterone and human growth hormone. just to get the terms straight, when they say tesstosterone, its an anabolic steroid, correct? >> it is an anabolic steroid but

also a normal hormone. we all have normal amounts. >> the number of men that are taking it has tripled over the last ten years. what do you make of that? >> it's a huge money maker for the industry. you can't turn on tv for more than an hour. >> see all the ads. >> yes. that never used to be there. the advertising is very clever. are you fatigued or tired, not performing as well? >> it hits all the hot buttons, and everyone says, hey, that's me. >> that's me. >> it seems to me there's sort of three categories. it will help you, it will do nothing for you, it could potentially be harmful for you. when it comes to testosterone, if you're taking it, maybe not necessarily needing it, could it be harmful? >> yes, it can, of course. any drug can be harmful, but relatively speaking, compared to

other anabolic agents, not so. >> human growth hormone? >> same thing. >> there's this notion hour hormone levels drop, certain hormones, as we age. with women, they talked about hormone replacement therapy. they thought it was going to be this great panacea for all women as they got older. just to put a lid on this, the average man, should they be taking testosterone? >> no. >> even as you get older and levels naturally drop off? >> they naturally fall, but that's life. >> that's a good response. the other thing that sort of strikes me, with regard to human growth hormone in the context of these athletes, from the studies i've read and the doctors i've spoken to, there's really no evidence it could actually increase your athletic performance out there. >> that's correct. >> so if there's no evidence of it -- first of all, two questions. why do people do it then? >> well, because they think it might or they don't want to miss

it just in case. it's a giant placebo. >> is it a big scam? >> you could call it a scam. i might call it a scam. >> does it help prevent injury? >> no. >> so it really doesn't do anything? >> doesn't do a thing. >> thank you so much for joining us. >> thanks for having me. >> we just got new evidence this week you should also be wearing your sunscreen, not just when you go to the beach, but all the time. the photographs you're about to see are stunning. it helps prevent cancer and also sunburns. we now have proof it kds also preserve your youth. the contrast is can shoishockin. this man was a trucker for 20 years. the more wrinkled side of his face was alongside his window. the sun did that. this phenomenal photo out this week are proof the sun doesn't just protect you from sunscreens and skin cancer, it protects you

from the age old curse known as wrinkles. photo aging comes from exposure to the sun's radiation, and specifically uva radiation. it's not the uvb radiation has linked to cancer. you can see it in these photos. this is the hand of a person with no skin damage, and this is someone with severe photo aging. in a study with 900 patients, those who used sunscreen daily over a 4 1/2 year period were 24% less likely to see these kinds of progressive changes. and doctors say this message will resonate with their patients. >> every patient, we try to tell them to use sunscreen, and believe it or not, just the message of preventing skin cancer doesn't always get through to people. so i'm hoping that maybe vanity will weigh out in this case. >> the rules for sunscreen, she says, are simple. >> you want to look for an spf of about 30. you want it to be broad spectrum, which means it covers

uva and uvb types of rays. the most important thing, though, is you want to pick one you will use. >> the sunscreen doesn't have to be expensive either. testing shows that low cost brands can work just as well. i do want to emphasize something, though, in terms of what to look for on that label. you want a sunscreen with an spf of around 30. higher numbers don't necessarily make a difference. they might give you a false sense of security or protection. also, make sure it covers a broad spectrum, meaning it protects against uva and uvb radiation. doctors say your best defense, limit the time you spend in direct sunlight. makes a lot of sense. now coming up, the top golfer whose pro career almost ended before it ever began. her name is stacy lewis. she needed a five-hour operation to fix her spine. then she came back. even in stupid loud places. to prove it, we set up our call center right here...

we're back with "sgmd." the lpga championship is in full swing in pittsburg, new york. one contender is stacy lewis. stacy held the number one ranking earlier this year, but i'll tell you, when i talked to her, she told me she went through years of pain to get here. at age 28, stacy lewis is living the life. >> is it's been fun. i just play golf every day. for a job, that's not too bad. >> she's been golfing since she was 8 years old, mostly just for the love of the game. >> was there a point in your life when you knew you were really, really good at golf? >> probably in college was kind of the time i said i could maybe do this as a professional. >> it wouldn't come easily. in middle school, stacy was diagnosed with scoliosis, a major curvature of her spine. her doctors hoped it would correct itself without surgery. >> i wore a back brace for 6 1/2

years, 18 hours a day. >> she only took it off to play golf, but it didn't work. she had to go under the knife. you scheduled the surgery. do you remember what that day was like? >> i thought i was done playing golf. they took out one of the ribs to do a fusion. go in from the side, had to remove the organs, the lungs, had a chest tube, all that kind of stuff. >> it took doctors five hours to insert a rod and screws into her spine and several months of rehab. >> i couldn't bend or twist for six months. so the doctor let me chip and putt a little bit. >> slowly but surely, her game started to come back. her swing even got a little better. >> when your hands are low like that, you tend to hit it left. and so when my hands got high, i started to hit a little fade to the right, which is actually, i think, a better shot for golf. so it actually worked out pretty good. >> worked out pretty well. today she's at the top of her game. think to yourself every now and then. >> it's strange. i definitely as a kid didn't

aspire to be in this position, but it the cool just to see the hard work pay off. >> it has paid off indeed. she is reportedly made close to $5 million in winnings. but lewis also knows it's not forev forever. >> i don't know how long i'm going to be able to play golf. i just feel very lucky to be doing what i'm doing. why not enjoy it? >> i could tell you that same attitude is also driving our fit nation six pack. last week one of our team members, ray timmy, she rode a grueling 32 miles for a bike challenge in colorado. it's something she didn't think she'd be able to do. i watched her improve by leaps and bounds when i trained with her two months ago in florida. i also learned an easy way to remember to control what i eat. i'll show it to you. it has to do with portion sidze. the thing i found really fascinating is thinking about your hands as an idea of what you should be eating. >> your hands represent a dinner

sometimes the biggest road blocks to happiness and getting what you want in life are toxic people around you. we've all met these bad guys and bad gals at one point or another, but now they're going to have to deal with dr. phil mcgraw. his new book is the best selling "life code the new rules for winning in the real world." he joins us now. thanks for being here. >> glad to be here. >> you find a lot of time to do different things. how long did it take you to write a book like this? >> i actually was working on it a long time, but i didn't plan to actually write the book. i just was actually kind of doing a little self-reflection and kind of an inventory on my own life about frankly people in

my life that had wound up betraying me, attacking me, or in some way trying to exploit me. so i started kind of writing about who are these people? just writing for myself. and i started seeing some patterns, and it turns out that these type people that i call baiters, which is just a term that stands for back stabbers, abusers, imposters, you just go right on down the line, to takers, exploiters, and reckless because they're reckless with your life. you just go right on down the line, and you find out that there are characteristics, traits, and profiles that characterize these people. >> as you're talking, i'm sure a lot of people are experiencing this. you're immediately thinking of people like this in your own life. the goal, i would imagine, is to get rid of those people in your life, which is probably easier said than done. >> it is easier said than done. but one of the things that we have to learn to do -- i'll tell you, the reason i decided to go

ahead and write this book is i think the world has changed. when the game changes, you need a new rule book. that's what "life code" is, it's the rules for winning in the real world. that means you've got to challenge some of the things you may have been taught. i was always taught, give people the benefit of the doubt. it's the christian thing to do. it's the right thing to do. it's a good thing to do. give people the benefit of the doubt. i think that is crazy. i think it is insane. why would we give somebody the benefit of the doubt? that's no less wrong than judging them without information. why not -- let's not do either. let's just gather data and make data-based decisions about people in our life. >> let's say you've come to this conclusion, you've figured out who the person is. how do you cut them off, so to speak? >> step one is trust your gut. trust your gut. how many times -- i bet you, you could go back and make a list, sanjay, of the people in your life you just had a funny feeling about. you aren't sure. you say, hey, don't be

judgmental, get over it. kind of go with -- you've got to listen to your gut. we don't tend to lie to ourselves about something likes to it when you listen to it, then you put them on a watch list. maybe you don't take them out of your life yet, but you put them on a watch list. you pay attention to see if they possess the evil eight. if they're using any of what i call the nefarious 15, the ways they exploit you. you watch for them and you go, wow, this person is infiltrating into my life, this person is trying to get me into a compromising conspiratorial disclosure about our boss or friend. if they'll gossip with you, they'll gossip about you. if you see people doing that, listen to your gut. those things begin to trigger, you know what, i'm putting up a wall here. you don't have to let people know what you're thinking, but you start backing away. you stop exposing yourself to that person. >> if you do decide that, you know, they need to be cut out,

there's an old adage that a tiger doesn't lose its stripes. can the person eventually in the future six months, a year from now, do you give them a second chance? >> these people typically don't improve. that's not true in every situation, but the prognosis is not good. in fact, if they go to therapy, it's usually court-ordered because they wouldn't go on their own. they go to therapy and a lot of them tend to get worse. so the therapist teaches them the symbol system, you need to feel and this and and they go got ya, got ya, it makes them better at disguising who they are. therapy tends to make these people worse. and you get away from them for a while and you go, you know, i kind of miss that person. no, you miss who you wish they

were. >> let's say you see a friend of yours who clearly is in one of those types of relationships with that kind of person, should you get in there and say, look, buddy, pay attention to what's going on here? >> it depends on how strong your relationship is. typically that doesn't work out for you. the best thing you can do is say to that person, you do what you want, but let me tell you i have bells going off about this person. i am going to pull back from this person. i am going to protect myself here. you have to make up your own mind. i'm going to tell you what i'm doing. then you've put them on alert. you've sounded the bell without them saying, well, you tried to break us up. are you jealous of our friendship? not at all. you guys do what you need to do. i'm telling you for me i'm taking a step back. if you want to go to the movies and you want the three of us to go, you two go ahead. you and i will catch up later. >> i enjoy speaking to you. i'm already thinking about some

actually an alzheimer's researcher studying alzheimer's disease and trying to cure this disease. and playing piano to try to get some inspiration to do that. i was originally doing some of the first studies trying to find genes that cause disease back at a time when no one knew how to do it. i wanted to build a full map of the chromosome. i was doing this as a student and i wanted to get finished so i picked the smallest one, which is chromosome 21. i remember that one day we were looking through this one gene we found and said, wow, this is matching up pretty well. so you had this aha-moment. i'm looking at probably what's the first alzheimer's gene, now we have a target for drug discove discovery. after i found the gene, my grandmother on my dad's side came down with alzheimer's disease. it literally steels who you are. there's no other disease that does that.
