sure where you're going. not specific plans and a bunch of people will get on and like do you want to come with us? yeah, right. and make a bunch of new friends. >> have fun with it. >> we'll see you back here at 8:00. got a lot to get to this half hour including a fascinating look at pain pills. if you have taken one what did it do to your brain and body? something i thought about a lot recently now that i'm a dad of three school age children. how early should school start? how early in the morning can kids learn? a wake-up call about wake-up calls. first the images on the internet. some of the more gruesome ones such as the beheading in iraq by isis. isis is a media savvy terrorist organization, make no mistake. the likes of which we haven't seen not even with al qaeda. i want to bring in brian

stealther. he's joining us from new york. thanks for being on the program. this is a modern terrorist group for lack of a better description. they are all over social media trying to intimidate people, trying to recruit people, trying to appeal to subset of millennials. these pose challenges. i'm curious, there are policies by companies like twitter and youtube when it comes to these things including the disturbing material? >> there are policies that are evolving as we speak. a decade ago it was al qaeda creating online magazines which was for them innovative at the time. now it's a group like isis using twitter or facebook or other tools we also use every day. in order to spread their messages and that is innovative for them at this time. twitter and youtube are having to figure out how to handle this. these websites almost always err on the side of free expression. i had a public relations person reach out to me concerned about

a family that he is helping, he represents a family of one of these people who have been detained either in iraq or syria, one of the americans that's being held hostage. he needed help reaching twitter to try to get tweets taken down that he said were directly in dangering his client and that family. soy was able to connect him to twitter to try to help with. that that's one small example of this situation where twitter and youtube and other sites like them, play a role. i don't think they possibly expected to when they were invented. you know what i mean. >> sort of the free speech, that's what they do the social media, empower the users. on the other hand some of this is disturbing. we know youtube yanked the beseeding video. twitter pulled photos, they september out some forceful tweets. are there -- do people get around in a room, how many are making that call? is it the co of twitter?

>> it's the ceo of twitter in this case who made his announcement saying that twitter was going to take action in the case of james foley and take those images down. it is lower level staffers, some of the same who also deal with cases of child abuse or child pornography. they do err on the side of free expression but it's tricky when there is such outrage about images that show up on these sites. i think we have to keep in mind that these messages are only as effective as we let them be. fear is only as effective as we let it be. and that's so important in these cases of terrorist messages. we don't have to choose to be afraid. we don't have to buy into the hysteria. >> brian, it's a brand new world. i'm going to turn 45, sometimes i feel like i'm on the more downward slope of it. >> i don't envying one of these executives at twitter or youtube who has to decide how to handle

this stuff. >> thanks for helping us out. appreciate it. i'll tell you as i said as a father of three young girls, the news this past week, they brought up a lot of questions in our family. and my good friend wendy walsh also a mom, a psychologist, and i'm sure deals with some of these same questions as well. personally and professionally. thanks for joining us, wendy. appreciate it. >> always happy to be here. >> an idea of how big social media companies are trying to address some of these problems and it seems a little ad hoc. it's a brave new world as they say. i want to talk about us parents. what is the obligation to protect? it's different in every household i know but what are your thoughts on that? >> i think the obligation is enormous. but the task is daunting. the problem is as soon as you put this little box in the hands of a child he have access to any piece of video or information in the world. it's very difficult to put parental controls on iphone specifically.

and pretty much because of parental need it's a necessity for us now to have our kids sort of digitally wired for us so we can reach them. so i think more than anything it's about teaching kids what is appropriate, what is not, what is acceptable, what is not and how to self-regulate and also to keep the lines of communication open so if their peer group is starting to get into areas more seedy areas of the internet that they will tell you so that you can circle in the other parents. >> so what do you do? first, do you do something pro actively or protectively? do you broach this issue with them before they bring it up with you? >> i think the worst thing is kids being exposed to bad news and having no ability to fix things. we feel bad as adults, right. so i think the important thing is for them to understand and i tell my girls this all the time. the only reason this really awful stuff is on the news because they have to fill the airwaves and a lot of channels and so the only -- the few rare times that something bad happens it just gets bombarded on the

media. it's not that it's everywhere. do you see it in your day? secondly, yes, there are people suffering and there is something we can do. recently someone connected me with the center for effective alterism who does economic analysis of the best charities in the world that save children's lives, and on their website giving what we can.org and i took all of my children -- my two girl there is the other day and they chose their favorite charities, one my daughter learned about fistula. with her allowance she brought them some surgery. i bought 10 mosquito nets at a cost of -- for $3 each so for $3 you can change a child's life. my older daughter went for water and making pure water. so you can do pro active things with the internet and save lives and that helps you deal with the other bad stuff you're seeing. >> that's such an important point. the idea that you feel empowered in some waxt even as journalists we go to some tough places but

the idea that we're reminding ourselves that this will make a difference somehow, that it shines a spotlight on an issue and more people will be caring about it, more compassionate about it. more will be compelled to act. i think it's an important point and the thing about the fistula surgery, water, there are so many things that people can help with. thank you. >> thank you. up next, we are going to shift gears. marijuana as a treatment for pain. we've done a lot of reporting on this, there are a lot of unknowns but one surprising and important benefit. ♪ man: [ laughs ] those look like baby steps now. but they were some pretty good moves. and the best move of all? having the right partner at my side. it's so much better that way.

e future? the future of kids? like a stock. not the kind of stock that's about making money. but a stock for social change. a whole new kind of investment called better futures. when you invest, it helps kids go to college. believe in us, invest in us. watch us grow. my name is sydni and i'm your dividend. prescription painkillers are the leading cause of accidental death in this country. did you know that? they are starting this growing number of people on the road to taking heroin.

cnn has been taking a closer look at this, pain pills and heroin. i want to start showing you how these drugs work on the brain and the body. before we can explore your brain on opiates we need to understand a few things. opiate is a chemical derived from opium and the key ingredient in heroin. the narcotics in the medicine cabinet, they are opiate-like. but they are man made and more commonly referred to as opiotes. how do they affect the brain? exerting pain relief to the rest of the body. chemicals flood the system, latch on to millions of receptoreceptor s peppered throughout the body. think of them as puzzle pieces. when they bind together, pain signals are dulled or they go away altogether. if the brain already has opiate receptors, doesn't that mean it can naturally provide pain relief? that's right.

feel good chemicals like endorphins are natural opiates, that dull pain and also give you a rush. the problem with man made opiates that mimic endorphins, take too many, and they can over well am the system, give you too much of a rush, that can lead to dependence or abuse. addiction becomes a bigger problem because opiates also slow down breathing and heart rate. mix them with other things that slow down your body, and everything could grind to a halt. in fact, every 19 minutes someone dies of an accidental prescription drug overdose. most of the time involves an opiate. more common than dying 18 car crash. if you want to avoid that don't take more than you are prescribed. don't use other people's prescripti prescriptions. never mix opiates with alcohol and maybe try other ways of alleviating your pain like over-the-counter pain relievers and exercise. >> also, there is a new report

that came out i found fascinating. it says that in states which pass medical marijuana laws, death from prescription drug overdose went down 25%. 25%. there's an obvious connection here. number of people who use marijuana do use it to to cope with pain. it seem as fair number are choosing it as an alternative to some of the pills you saw there. legal issues aside which medicine to use is a question for you and your doctor, your health issues, personal concerns, all a little different for everyone. i want to be clear, the potential for these deadly side effects is less with marijuana than with opiate pain pills. we have not found a documented case of any one dying from a marijuana overdose. >> daylight savings time doesn't end for two months but we're getting a head start here. should our kids be getting an extra hour of sleep right now? i'll tell you why people say that is the case, who says it is the case, but first, we got this week's human factor.

as a child jason loved making home movies. he was 18 when he made his first film. and 25 when he was diagnosed with primary progressive multiple sclerosis. >> walking slow up and down the subway step and walking like i was drunk during the day. >> ms is a disease where the body's immune system attacks the central nervous system, damaging or destroyving nerve fibers. the filmmaker traveled making nine films, then turned the camera on himself. >> this is like every day. >> documenting the ravages of his disease and the struggles people with disabilities have living in new york city. >> we're not sub human. people shouldn't be asked to do the impossible. >> in the seven years it took to make the movie, "when i walk" desilva went from walking to

using a walker to a wheelchair and now a scooter. his vision has started to deteriorate. his hands curl, making it impossible to hold a camera. passionate about making the city easier to negotiate for people with disabilities he and his wife created a map of all of the places in the city that are wheelchair accessible. >> some of the things i'm getting is making a difference. but that's what keeps me going. that's how i can stay positive. >> human factor is brought to you by cancer treatment centers of america. care that never quits. ñzóó

we're back with this. with the start of the school year transitioning kids to get up earlier is a challenge. it's a challenge for us. one group of doctors is saying let them sleep. it's 5:22 a.m., and for many high school kids, it's time to get up for school. the bus comes at 6:20, the first bell rings at 7:25. a new report says that's too early. it says for middle school and high school students school shouldn't start before 8:30. >> melatonin a hormone that tells our body what time it is to go to sleep is secreted later in teens. as a result teens cannot fall asleep at 10 or 11:00. >> on average teens need more sleep than younger school kids,

about nine hours every night. only one out of ten teens sleeps that much. according to a new study. the rest are sleep deprived. and the result, decreased ability to think and concentrate, not to mention a heightened risk of obesity, depression, a higher risk of being in a car accident. i'm fascinated >> a lot of us have kids trying to decide what time they should wake up. ron clark is the founder of the ron clark academy, prominent middle school that serves as an educational training facility for teachers across the country. so, you have heard about this report. let me ask about the academy. what time do the kids start? >> they start at 8:00. some arrive as early as 7:15. >> how do they perform? >> we love it. i'm not a morning person. what's best for kids, the kids

in our 8:00 classes focus better, test scores are better, teachers want their classes at 8:00 a.m. because kids tend to retain more information earlier in the morning. >> what drives the decision, though in terms of when to start? i'm sure part of it is, obviously, trying to gauge how the students will do. there are a lot of forefactor that weigh in? >> it's society. parents have to get to work. they need to drop their kids off at 7 lone 15. it's to accommodate the society we live in. >> school buses recycle from one group of students to the next group of students so you have to start them at staggered times as well. things like that make a difference. when you hear the studies, saw the piece there, what do you make of it? you have been at this for a long time. does it play a role for you in terms of when you start school >> lack of sleep is an important thing. it's a factor we deal with all the time with our kids. there are things parents can do having the clothes laid out the

night before, minimize the time it takes to get ready in the morning. once they finish homework, it becomes internet and texting. doctor said kids can't fall asleep at 10:30 or 11:00 it's because their kids are wired with technology. >> melatonin can be decreased. >> i want my kids to be exposed to that and get that members of the jury regardless of the time we're forcing them to wake up. >> exactly. >> thank you. come back any time. >> i got one more story for you today. this is from one of my fellow travellers. unique travel accessory. it caused an inflight fight so severe it resulted in the plane

being diverted. true story. you got to see it to believe it. . transamerica. transform tomorrow. e future? transamerica. the future of kids? like a stock. . invest in us. watch us grow. my name is sydni and i'm your dividend.

. we've all been there, crammed into this most, sometimes smelly overcrowded flight. take it from me. i often feel i'm in the air more often than my own bed. but there's this new gadget. you may have heard about this. it's as devious as it is ingenious. here's jeanne moos to explain. >> reporter: a new air war has broken out in the airspace over your knees. >> the knee defender is a device that keeps people from reclining their airline seat into your knees. >> reporter: you put it on your tray table to keep the seat from going back. >> do you get your knees crunched? >> sometimes. >> reporter: nobody was grinning

on a flight that had to be diverted after a fight broke out. a 48-year-old passenger deployed the knee defender to stop the seat of the female passenger in front of her. when she couldn't reclined she flagged down a flight attendant to ask him to remove the knee defender. he refused. they were both kicked off the plane. when it happens to others it's funny. but as this reviewer of the knee defender joked -- >> the captain turned off the seat belt sign. feel free to move about the head and punch the guy in the head with the knee defender in seat 14b. >> i was tired of being bumped in the knees. >> reporter: this was one of the early versions. now it looks like this and sells for 21.95. it's as devious as it is ingenious. everyone retalked to agreed.

>> they are kind of evil. >> it sounds terrible. >> why? >> to make somebody else uncomfortable. >> it causes problems. people paid for their says and they want to push it back. that's their god given right. >> reporter: the knee defender comes with a courtesy card for to you hand to the passenger in front of you. i've provided you with this card i have long legs and if you recline your seat you will bang into my knees. >> united bans the knee defender. >> reporter: the story about the fight seemed to being a great for the knee defender's business. the website crashed due to unexpectedly heavy demand. whether you call it a knee defender or a knee to the grow in, can we just remember about the wonder of flying. >> you're sitting in a chair in the sky. >> reporter: jeanne moos, cnn,

new york. >> i should note right here on the device itself it says be courteous to people and listen to the flight crew. more seriously being forced to sit in cramped quarters for a long period of time can cause joint pain and stiffness. in rare cases it can cause a life the threatening blood clot. the cloth, it forms in the leg and then can lodge potentially going up into your lungs. one study found the risk goes up by 18% for every two hours of sitting. still rare but it can happen. quick trick that i use. these are my socks. i do the show sometimes without shoes on. i'll sit in my seat, lift up my legs and rotate around the ankles. the goal is to keep the blood flowing in your feet and calves.

if you see me up there say hi. that's going to wrap things up. "new day" sunday continues right now. aren't you up bright and early on a sunday. i'm so glad you're with us. >> this is "new day" sunday. for more than two months now residents in northern iraq in a town there they have feared for their lives. >> villagers in the town of amali have been surrounded by isis. no food or water since june. this morning, though, following days of fierce fighting iraqi security forces broke ti sis siege. this is according to a retired
