i test . good evening, thank you for joining us. tonight, a heroic rescue was caught on camera. a man is saved after going overboard, on one of the largest cruise ships in the world. we hear from the witnesses who helped him to safety. and this is not the first time someone has fallen off a cruise ship. abc's cecilia vega takes a closer look. >> reporter: it was early in the

morning off these choppy waters off the coast of cozumel, mexico. >> i heard what i thought was a bird in the water, a speck in the water. >> reporter: the speck turning out to be a 22-year-old man. >> i noticed it was a young man screaming help me as loud as he could. somebody please help me. >> reporter: scott and stephanie campbell passengers on the ship spotted him. >> i right away got on the phone and called zero. >> over the p.a. there was a call made mr. mob. >> reporter: that man had somehow fallen into the caribbean off another cruise ship sailing the same route earlier that morning. >> and the crew took over from that point brought the ship to a stop. circled around him. that is when i started videoing. >> reporter: the rescue all caught on camera by david hearn, who was also watching from the deck of the magic. >> it was very surreal.

i never imagined in my lifetime that i would ever see anything like that. >> reporter: these witnesses say people on board threw the man a life vest. the crew launched this life boat and raised to save him. >> once i saw him start to swim i knew he was okay. >> it made us feel very good to see that in an emergency that is how quickly they responded. >> reporter: according to the eyewitnesss, the entire rescue taking only 30 to 45 minutes. >> they do these safety drills before we even leave port and we're sitting there thinking get this over with we're never going to need this information. and to actually see it put to use was, wow, they're on their game. >> reporter: disney, the parent company of abc news did not issue a statement about the ship's rescue. in a statement, royal caribbean said we are grateful for other ship's assistance. it is not known exactly how the man went over board or where

exactly he fell from. but it is 21 stories tall. a drop like that would be like dropping from the niagra falls, the extent of the man's injuries are not known. but according to eyewitnesss, he was able to swim and do more. >> when they wheeled him off he was in a sitting up position on the stretcher. and he was waving to everybody and completely alert. >> reporter: but no doubt this experience must have been terrifying. something sarah kerby knows all too well. >> i remember looking over the water, looking at the ship and the next thing i knew i was falling. >> reporter: this is video of her falling in 2012 on a 30th birthday cruise from miami to jamaica. >> everybody was drinking to excess, and i was enjoying it with everybody on the cruise. we decided to leave the bar, go back to our room. the next thing i remember is going out on the balcony. >> reporter: minutes later recorded by a camera on the ship she is falling straight down

towards the sea first slamming to a life boat then dropping another five stories into the water. >> i was so scared. and i was going to do everything in my power to survive. >> reporter: she was badly hurt, broken bones in her face fractured ribs and a torn artery. >> i remember being in a lot of pain, the water would crash into my mouth and i would choke. i just prayed to god over and over, please don't let me die out >> reporter: an hour and 31 minutes after she fell she was spotted by the crew and rescued. >> and we are now bringing her on board the vessel. >> reporter: according to the cruise industry, people falling overboard are rare. >> it is actually one of the rarest events that happens on cruise ships. the rate of one overboard for every one million? 650,000 passengers. >> reporter: still more than you want. by one expert they counted 22 people going over board from cruise ships last year. >> you don't get blown or swept

off a cruise ship. it does not happen. all of these incidents unfortunately are accompanied by some reckless or deliberate act. >> reporter: kerby still can't say exactly why she fell. but she is suing. her lawyer said the ship should have saved her sooner. >> the vessel should have been stopped. they should have been throwing the life wings over board to help her. >> reporter: in a statement to abc news, carnival cruise lines said the suit allegations are completely unsupported and contradicted by the allegations in the case. the case is still pending. so how do you make sure this does not happen to you? is there one reason that people fall over? >> the easiest way people fall over is they're on the cruise ship to have a good time. they are not paying attention. >> reporter: alcohol plays a role? >> alcohol plays a role a lot of times. >> reporter: let's hope you don't, but what if you do? >> if you land in the water, immediately do what you can to control your breathing.

you can actually drown in a minute or two just from panicking, we suggest people moving away from the vessel so that somebody on board can see you. >> reporter: regardless how kerby or this man ended up in the matter, technology is being developed to make sure they sense somebody going over board as soon as it happens. >> we have this screen here showing as soon as it happens. >> reporter: this one has a system to see how it works. my colleague took a plunge. >> three, two, one! >> reporter: by the time she hits the water an alarm already sounds and the system indicates exactly where she went overboard. >> the venders of these systems are very anxious to bring them to market. you can have birds set them off, debris of any kind floating in the air, set them off. the detection systems are not

perfected. >> reporter: some cruise lines say they have yet to see a system that meets their standards. in our case our demonstration was on a boat not a giant cruise ship and in calm water. tonight, one man happy to be on land a disastrous situation was averted by a stunning stroke of luck. >> it was a miracle he ended up where he did. >> reporter: for "nightline," i'm cecelia vega in los angeles. next project youth, meet the reason dan harris is happier, by one simple life change. and just when you thought you saw it all, one passenger on a bus will really surprise you.

it's a new year a lot of people are looking for resolutions to improve their life, tonight, we have a potentially game-changing solution from our co-anchor dan harris. as you're about to see dan had a low point in his life and found his way back. here, you're about to see the first installment of his series. >> ten months ago, i took a huge risk and decided to tell a very personal and embarrassing story that involved a secret drug habit, a national panic talk and then later, my embracing a habit that i always thought was ridiculous. as i made the rounds promoting my idea on "the view."

and the colbert report? >> are you like a club kid? did you have a pacifier in your mouth? >> i may have looked calm but underneath i was terrified. i was afraid these revelations could ruin my career. but in fact everything was fine, people were actually reading the book and i was hearing from them thousands of them. >> and it definitely opened my eyes. >> i totally identified with him. >> i'm like, he is my people. >> reporter: and i realized all sorts of people were dealing with the issue i had been battling for years. the voice in my head i'm talking about the incessant inner narrator we all have. it is the voice that chases you out of bed in the morning and yammers at you all day long. >> this is what i need to do today, the five meetings here is the thing i forgot. >> reporter: it frequently has us judging other people.

>> where is david bowie right now? and being ruthlessly critical. >> i have horrible posture, i'm not a very good father maybe i'm ignoring my youngest daughter when you're being critical of yourself, you're doing something productive. >> reporter: for me the voice in my head was largely about one thing, ambition as a young reporter i volunteered to cover war zones frankly not thinking about the psychological effects. when i came home i got depressed and blindly, mindlessly self-medicated with recreational drugs, including cocaine and ecstasy, a stupid decision that ultimately led to this. this is me filling in on

morning america "back in 2004 just seconds into the show, i had an anxiety report. >> it may also lower their risk for cancer but it is too early to prescribe. >> reporter: at this point i knew i was helpless so i bailed right in the middle. that does it for news we'll go back right now to robin and charlie. as i later learned from my doctor, the drugs i was taking in my personal life raised the level of adrenalin in my brain, and almost certainly caused me to have the panic attack. i needed to find a new way to deal with my inner narrator. and after a long strange journey with mega churches and self-help, i found something that was supremely helpful,

meditation. my readers were similarly skeptical. >> why would i want to turn my brain off. >> that sounds so boring. >> reporter: meditation is actually simple secular and scientifically validated. studies show that it can lower your blood pressure, boost your immune system. and effectively re-wire key parts of your brain, many high-functioning executives pro athletes and even u.s. marines are using the meditation to be more effective and less yanked around by their emotions. >> i am a driven person and i was very worried that something like meditation and yoga they don't fit into my a-type personality. >> reporter: like the creator whirl wind behind the tv show doc mcstuffin. she started to meditate after

reading my book and helps with self-criticism. >> it is exhausting to be in th it into a bigger cycle where we get movement. i think it allows me to take a moment when negative responses come in. and not take it so personally. >> reporter: and then there is jason hammel one half of an indy rock band. >> when i started meditating i was afraid what would happen is that i would stop and it would breeze over all the passion. >> reporter: he found that by meditating, he actually has honed his creative edge. >> it actually allows you to create better and express what you're thinking more because it will focus on that one feeling or thought. >> i think at first, it was making me like more selfish, ultimately it is a great thing

for him and a great thing for all of us. >> reporter: in my case meditation has helped me cut back on mindless behavior like losing my temper checking my e-mail in the middle of conversations or eating when i'm not hungry. now, it won't make your life a non-stop parade of unicorns and happiness, which is why i came up with my book 10% happier. however, as i learned from my readers, meditation can provide a happiness boost that goes well beyond 10%. alice graduated last spring with a degree in nursing. >> i felt like i was miserable, thinking about why am i not getting this job yet? >> reporter: she said she was consumed by the anxiety of her future. >> the one thing was having my job, i feel like with meditation, i feel this is the time for me to start living. >> reporter: the day after we met her she had a job interview and she says meditation helped

her prepare. >> i felt like i was in the zone, answering the questions and i felt like it showed my best side. i think it helps. >> reporter: and then there is chris. >> i was desperate. it was a desperate time for me. >> reporter: he is a father of two and a recovering addict. last summer, he says he couldn't see a future at all. >> i got to the point where the inner dialogue was telling me how awful and stupid am. and i attempted to act out, developing a plan here is how i will commit suicide. >> reporter: he says now meditation has helped him get to a much much better place. >> who know what is the future will bring? i'm here i could have killed myself. i could have missed out on so much. i am so grateful for this idea of meditation. >> reporter: so think about it. if meditation can work a recovering addict, a young professional, a rocker a tv executive and a fidgety,

here is abc's neil carlinski. >> reporter: okay, so lassie was really good at figuring stuff out and finding her way, and uggy the jack russell you may recognize from flicks like water for elephants and "the artist" even had them launching a campaign for the artist. and this one has eclipsed all. no special effects here just a dog who rides the bus all by herself. we spent the day bouncing around downtown sateattle with eclipse. full disclosure i had no idea where to get off the bus and found myself following the dog. she looks out the window, and no joke she knows exactly when it is fine for her to get off. so where does a bus-riding dog

go? the dog park of course. at the park we met jeff young, who says he usually rides with his dog, but on some occasions she has done it totally on her own. >> just the dog to the park she rode it with me so many times. >> reporter: it is d. there are not many who could get away with licking the seat in front of them and still be the most popular passenger on board. of course, public transportation can be grueling. eclipse is the one passenger nobody complains about when she nods off in front of you. in seattle. for the record eclipse gets the four-legged discount. she rides the bus for free. thank you for joining us on abc news, world news now is coming up soon with overnight breaking news. soon into "good morning america" tomorrow and as always we're on
