0:00:23 > 0:00:25He's Dr Chris.
0:00:25 > 0:00:26He's Dr Xand.
0:00:26 > 0:00:29And yes, we're identical twins!
0:00:29 > 0:00:34Do you know, your body does heaps of amazing things every single day.
0:00:34 > 0:00:35That is incredible!
0:00:35 > 0:00:37And we're going to show you how.
0:00:37 > 0:00:40Wah! You've cut him in half!
0:00:40 > 0:00:42We've got incredible experiments...
0:00:42 > 0:00:44Whoa!
0:00:44 > 0:00:45And real-life medical emergencies...
0:00:45 > 0:00:47The doctor's going to make it all better.
0:00:47 > 0:00:48Ouch!
0:00:48 > 0:00:51We'll be turning our bodies inside out...
0:00:51 > 0:00:53Oh, yuck!
0:00:54 > 0:00:55..to show you what you're made of.
0:00:56 > 0:00:58You should see a doctor.
0:00:58 > 0:00:59I'd better go find one.
0:01:00 > 0:01:03Ahem? "Dr Xand?" Hmm?
0:01:06 > 0:01:09Coming up today on Operation...
0:01:09 > 0:01:10Ouch!
0:01:12 > 0:01:15It's bath time for me and Xand.
0:01:15 > 0:01:17Oh, oh!
0:01:17 > 0:01:18This is hot!
0:01:18 > 0:01:21Our travelling clinic is ouch and about!
0:01:21 > 0:01:23Can I see the next patient?
0:01:23 > 0:01:26Will Xand's body give him away when he tells a fib?
0:01:26 > 0:01:28I like to do ballet dancing.
0:01:28 > 0:01:30OK.
0:01:30 > 0:01:32But first...
0:01:32 > 0:01:34let's see who's turned up in accident and emergency.
0:01:34 > 0:01:36This is not for the squeamish!
0:01:36 > 0:01:37Wuh?!
0:01:39 > 0:01:41At Alder Hey Hospital in Liverpool,
0:01:41 > 0:01:4413-year-old Scott has come in with an injured leg.
0:01:44 > 0:01:46I thought it was a scratch.
0:01:46 > 0:01:48I turned round to look at my leg
0:01:48 > 0:01:50and there was a big chunk of me leg missing.
0:01:50 > 0:01:52How on earth did you do that?
0:01:53 > 0:01:57Scott was out riding his mountain bike with his friends.
0:01:57 > 0:01:58On a mountain?
0:01:58 > 0:01:59Hello, goaty!
0:01:59 > 0:02:01Don't be ridiculous, Xand, they were just in the street.
0:02:01 > 0:02:04Righto. They're not wearing helmets!
0:02:04 > 0:02:05I know, Xand.
0:02:05 > 0:02:08They were doing wheelies to see who could go the furthest.
0:02:08 > 0:02:10Whoa, dangerous stuff!
0:02:10 > 0:02:14Yep, and Scott was mid-wheelie when suddenly his foot slipped off
0:02:14 > 0:02:17the pedal, and his leg scraped on the gear cog.
0:02:17 > 0:02:19Well, he's lucky he didn't fall on his head!
0:02:19 > 0:02:21Is he OK?
0:02:21 > 0:02:23Well, at first he thought it was just a scratch,
0:02:23 > 0:02:26but when he saw it, he cried out.
0:02:26 > 0:02:27Ouch!
0:02:28 > 0:02:31OK, so how bad is this cut?
0:02:31 > 0:02:32You can almost see his bone.
0:02:32 > 0:02:35It's quite shocking, really, to look at.
0:02:35 > 0:02:38Ooh, it does sound bad. Let's see.
0:02:38 > 0:02:41OK, Xand. If you're squeamish, look away now.
0:02:42 > 0:02:44Whoa!
0:02:44 > 0:02:46It's a huge cut!
0:02:46 > 0:02:48Must be sore!
0:02:48 > 0:02:51So next, Scott needs an X-ray to check his bones.
0:02:52 > 0:02:56There's the big hole right there, but luckily nothing's broken.
0:02:56 > 0:02:59The worry now is possible tendon damage.
0:02:59 > 0:03:02Tendons are what holds muscle to bone, and a tear to them could
0:03:02 > 0:03:05affect the movement of Scott's foot.
0:03:05 > 0:03:09Here to check that out is...
0:03:11 > 0:03:13Can I just ask you to move your toes a bit?
0:03:13 > 0:03:15They're wiggling! Well, that's good news!
0:03:15 > 0:03:18And can you move your foot?
0:03:18 > 0:03:21The movement of his foot suggests that the tendons are intact.
0:03:21 > 0:03:24But we still cannot be sure because if they are partially teared
0:03:24 > 0:03:27we would still need to repair it.
0:03:27 > 0:03:28That's one of the concerns at the moment.
0:03:28 > 0:03:30Then we'll make him comfortable
0:03:30 > 0:03:33and then await for further action to take to theatre.
0:03:33 > 0:03:35OK?
0:03:35 > 0:03:38So, Scott's having an operation to fix the hole in his leg and
0:03:38 > 0:03:41make sure there's no other major damage.
0:03:41 > 0:03:43We'll see how he gets on later in the show.
0:03:48 > 0:03:52And now to our lab for some amazing body experiments.
0:03:52 > 0:03:53Ouch!
0:03:54 > 0:03:57Just don't try anything you see here at home.
0:03:59 > 0:04:02As you can see, Chris is on an exercise bicycle.
0:04:02 > 0:04:05It's hardly a bicycle! It's more of a unicycle!
0:04:05 > 0:04:08It doesn't even have handles! It's extremely uncomfortable!
0:04:08 > 0:04:10Shh, this is science!
0:04:10 > 0:04:11The reason Chris is on the bike
0:04:11 > 0:04:15is because I want him to try and heat up this beaker of water to exactly...
0:04:17 > 0:04:19I think I got the short straw here!
0:04:19 > 0:04:21My bike is actually generating electricity
0:04:21 > 0:04:24to heat up the water in that beaker.
0:04:24 > 0:04:26- Do you need a rest, Chris? - Oh, yeah, thanks.
0:04:26 > 0:04:29Well, you can't have a rest! Come on, keep going!
0:04:35 > 0:04:37Perfect. You can stop.
0:04:37 > 0:04:40Oh, you've overshot, it's up at 38.
0:04:40 > 0:04:42Sorry, I'm going to have to add a load of ice
0:04:42 > 0:04:44and then we'll start all over again.
0:04:44 > 0:04:45That's good, keep going.
0:04:45 > 0:04:49Now, 37 degrees isn't just any old random temperature we've
0:04:49 > 0:04:52plucked out of the air - it's the temperature of your body's core,
0:04:52 > 0:04:55which is this bit here where all your internal organs are.
0:04:55 > 0:04:58Oi, you don't need to prod me!
0:04:58 > 0:05:02So, your organs work best at 37 degrees, and your body tries
0:05:02 > 0:05:05to keep your insides at exactly this temperature.
0:05:05 > 0:05:07You know what? I've had enough.
0:05:07 > 0:05:09I think I have clearly demonstrated that trying to keep
0:05:09 > 0:05:12something at a constant temperature is hard work.
0:05:12 > 0:05:16But your amazing body does it every day without you even noticing it,
0:05:16 > 0:05:19and no matter what you throw at it, as we're about to show you.
0:05:19 > 0:05:23Today, we're going into battle with our own bodies to see if we
0:05:23 > 0:05:26can get our core body temperatures to change.
0:05:26 > 0:05:27It's time for...
0:05:30 > 0:05:32- Snappy name, Xand!- Thank you.
0:05:32 > 0:05:35Now, we can only do this experiment because we're doctors
0:05:35 > 0:05:38and it's being done in VERY controlled conditions.
0:05:38 > 0:05:40For this battle, Xand is going to sit
0:05:40 > 0:05:42in a super-hot bath for ten minutes.
0:05:42 > 0:05:44While Chris will sit
0:05:44 > 0:05:46in an ice bath for ten minutes.
0:05:46 > 0:05:48He'll be freezing and I'll be boiling,
0:05:48 > 0:05:51but will it affect our core temperature?
0:05:51 > 0:05:53Let's find out.
0:05:53 > 0:05:56So, I shall be Captain Cryogenic!
0:05:56 > 0:05:58I shall be...
0:06:01 > 0:06:02..Dokter Warm.
0:06:02 > 0:06:04Dokter Warm? Is that the best you can do?
0:06:04 > 0:06:06I think it's quite a good name
0:06:06 > 0:06:09for a core-body-temperature-fighting superhero!
0:06:09 > 0:06:12What's so great about Captain Cryogenic anyway?
0:06:12 > 0:06:14Well, for a start the words Captain and Cryogenic
0:06:14 > 0:06:16both begin with the same letter.
0:06:16 > 0:06:17Hmm!
0:06:19 > 0:06:21OK, so we're ready to go!
0:06:21 > 0:06:24It's time to try and beat our core body temperatures.
0:06:24 > 0:06:25Let battle commence!
0:06:25 > 0:06:27Ah! Ah!
0:06:27 > 0:06:29So Chris gets into his ice bath.
0:06:29 > 0:06:31Oh, oh!
0:06:31 > 0:06:34While Xand pops into the toasty warm bath.
0:06:34 > 0:06:35This is hot!
0:06:35 > 0:06:38We've already taken our core temperatures and we both got
0:06:38 > 0:06:41a reading of 37.7 degrees Celsius.
0:06:41 > 0:06:43Now, to do this experiment properly
0:06:43 > 0:06:47we've put special super-accurate thermometers inside our bodies.
0:06:47 > 0:06:49Can you guess where they are?
0:06:49 > 0:06:50Is it..
0:06:55 > 0:06:57The answer is C.
0:06:57 > 0:07:00But don't be alarmed, they're coming out as soon as all this is over.
0:07:00 > 0:07:03Remember, we can only do this because we're doctors.
0:07:03 > 0:07:05All we can do now is wait
0:07:05 > 0:07:08for our bodies to feel the effect of the different temperatures.
0:07:08 > 0:07:11Xand, your face has gone bright red!
0:07:11 > 0:07:12You can see I'm sweating.
0:07:12 > 0:07:15Now, that's good, cos it means my body's getting hotter,
0:07:15 > 0:07:18but it also means my body's fighting back!
0:07:18 > 0:07:21The sweat evaporates, taking heat with it.
0:07:21 > 0:07:23Now, I'm feeling very cold, but I'm shivering,
0:07:23 > 0:07:26and that's a reflex that your body uses to jig around
0:07:26 > 0:07:29and generate heat, so I know it's fighting back!
0:07:31 > 0:07:32Ten minutes are up.
0:07:32 > 0:07:34Time to find out if we've managed
0:07:34 > 0:07:36to beat our core body temperatures.
0:07:36 > 0:07:40From this thermal imaging camera we can see how warm Xand's outer body
0:07:40 > 0:07:44is, and that's because his blood has rushed to his skin to cool him down.
0:07:44 > 0:07:48And Chris's body on the outside is cold and blue.
0:07:48 > 0:07:50That's because his blood has rushed
0:07:50 > 0:07:52to his vital organs to keep them warm.
0:07:52 > 0:07:56But the important question is, have I managed to beat my body and
0:07:56 > 0:08:00bring my core temperature below 37.7?
0:08:00 > 0:08:05And have I managed to bring my core temperature above 37.7?
0:08:07 > 0:08:10What?! 38.4!
0:08:10 > 0:08:12I've actually got warmer!
0:08:12 > 0:08:15My body has fought against the cold so effectively
0:08:15 > 0:08:18that it's made my temperature rise!
0:08:18 > 0:08:19Well, so much for my attempts
0:08:19 > 0:08:21to defeat my body's own core temperature!
0:08:21 > 0:08:23Let's see how Xand got along.
0:08:23 > 0:08:25Chris, that was a crashing defeat for you,
0:08:25 > 0:08:28but I'm hoping I've done a little better.
0:08:28 > 0:08:2938.1!
0:08:29 > 0:08:32So I've beaten my core body temperature
0:08:32 > 0:08:34by four tenths of a degree.
0:08:34 > 0:08:36That's really not very much at all.
0:08:36 > 0:08:39My body's done an amazing job of keeping me cooler than that
0:08:39 > 0:08:43bathwater with all the going red and sweating!
0:08:43 > 0:08:46No matter what your surroundings, your body fights hard to keep
0:08:46 > 0:08:51your core at the ideal temperature of 37 degrees Celsius.
0:08:51 > 0:08:55Now, Chris - I've been thinking about an alternative name for Dokter Warm.
0:08:55 > 0:08:56What about...?
0:08:58 > 0:09:01Right, Xand, that's a great idea!
0:09:01 > 0:09:04I think you should go and get a hat made straightaway.
0:09:04 > 0:09:06That's a great idea! I'll go and do that at once!
0:09:06 > 0:09:07Beautiful idea!
0:09:08 > 0:09:12Now we're getting Ouch & About with our mobile clinic.
0:09:14 > 0:09:18Today, we're at a theme park to help solve your medical mysteries.
0:09:18 > 0:09:20If you're anxious about an ailment
0:09:20 > 0:09:21or curious about a condition,
0:09:21 > 0:09:23then the Ouch Mobile
0:09:23 > 0:09:24is the place for you.
0:09:24 > 0:09:25That is incredible!
0:09:25 > 0:09:29Xand is preparing the clinic, ready for his first patient.
0:09:29 > 0:09:33And Chris is out in the park to answer your burning questions.
0:09:33 > 0:09:34Now we're ready for business.
0:09:34 > 0:09:36Can I see the next patient?
0:09:36 > 0:09:37First up is Anastasia,
0:09:37 > 0:09:41with something she feels she needs to keep a watch on.
0:09:41 > 0:09:44So, Anastasia - what's brought you to the Ouch Mobile today?
0:09:44 > 0:09:47I have something strange hidden under my watch.
0:09:47 > 0:09:49So, what's the diagnosis, Doc?
0:09:49 > 0:09:50Sounds to me like a case of...
0:09:54 > 0:09:58That's exactly what I'd say. Let's have a look, then.
0:09:58 > 0:09:59Oh, that's great.
0:09:59 > 0:10:01So, that is what a doctor would call a...
0:10:04 > 0:10:05It's a mole.
0:10:06 > 0:10:09So, what you can see here is a very typical mole.
0:10:09 > 0:10:11It's quite a big one, but it's got irregular edges,
0:10:11 > 0:10:14it's a patch of darker skin than the surrounding skin
0:10:14 > 0:10:18and it's slightly raised, but it looks like a very typical mole.
0:10:18 > 0:10:20How do I know if it's dangerous?
0:10:20 > 0:10:22Sometimes moles can cause trouble.
0:10:22 > 0:10:24The things that you'd look for, if it changes shape,
0:10:24 > 0:10:28it changes size. If it changes colour, particularly - or it
0:10:28 > 0:10:30becomes itchy, or it starts to bleed at all.
0:10:30 > 0:10:33Any of those changes, you want to take it to your GP
0:10:33 > 0:10:34and get them to have a look at it.
0:10:34 > 0:10:37Thanks for answering my questions, Dr Xand.
0:10:38 > 0:10:39Away from the clinic,
0:10:39 > 0:10:44Chris is Ouch & About in the park solving your medical mysteries.
0:10:44 > 0:10:47Dr Chris, why do you get pins and needles sometimes
0:10:47 > 0:10:49when you lie in a weird position?
0:10:49 > 0:10:52When you're in a weird position with either your leg or your arm,
0:10:52 > 0:10:55what's happened is you've cut off the blood supply to that limb.
0:10:55 > 0:10:58So, often you'll find that the arm or leg goes dead
0:10:58 > 0:11:00and you can't feel anything at all.
0:11:00 > 0:11:02And as the blood and oxygen go back to the nerves,
0:11:02 > 0:11:06they wake up again and start sending all sorts of weird signals
0:11:06 > 0:11:09back to your brain which you feel as pins and needles.
0:11:09 > 0:11:11Why do you have a stitch when you run?
0:11:11 > 0:11:12You'll notice your stitch is worse
0:11:12 > 0:11:15if you run soon after you've eaten, and that's cos when you run,
0:11:15 > 0:11:18you want to send all the blood in your body to your muscles
0:11:18 > 0:11:22so they can do work, and that takes the blood away from your guts.
0:11:22 > 0:11:25And if you've eaten food, your guts are trying to digest the food
0:11:25 > 0:11:28and if they lack blood then they start to hurt
0:11:28 > 0:11:30and they start to complain cos they want more blood.
0:11:30 > 0:11:32So if you run on an empty stomach
0:11:32 > 0:11:35and you warm up slowly, you won't get the stitch.
0:11:35 > 0:11:39Back at the clinic, there's a familiar face in the waiting room.
0:11:39 > 0:11:41Can I have the next patient?
0:11:41 > 0:11:43- Oh, it's you again, Anastasia! - Hello!
0:11:43 > 0:11:45Yep, she's back for more!
0:11:45 > 0:11:47So, Anastasia, how come you're back?
0:11:47 > 0:11:50All my friends in my school have an innie bellybutton
0:11:50 > 0:11:52but I have an outie.
0:11:52 > 0:11:54What's the diagnosis, Doc?
0:11:54 > 0:11:56Sounds to me like a case of...
0:12:00 > 0:12:01Spot on.
0:12:01 > 0:12:03That is a very impressive
0:12:03 > 0:12:04outie bellybutton.
0:12:04 > 0:12:06So why do I get an outie bellybutton?
0:12:06 > 0:12:09When you're inside your mum before you're born, you need to get fed.
0:12:09 > 0:12:12And you don't get fed through your mouth, you actually get fed
0:12:12 > 0:12:15through your bellybutton through a thing called the umbilical cord,
0:12:15 > 0:12:18and that gets blood and nutrients and oxygen into your body.
0:12:18 > 0:12:20And after you're born you don't need it,
0:12:20 > 0:12:23so we clamp it off, and the cord just dies and falls off.
0:12:23 > 0:12:25And usually, when things die and drop off,
0:12:25 > 0:12:27you get a bit of a scar formation -
0:12:27 > 0:12:30that scar tightens up and pulls the bellybutton in.
0:12:30 > 0:12:32But in lots of people that doesn't happen.
0:12:32 > 0:12:34But it's not a problem, it's completely normal.
0:12:34 > 0:12:35In fact, it's quite special.
0:12:35 > 0:12:38Ooh, I'm special!
0:12:38 > 0:12:40Job done for today. Clinic closed.
0:12:41 > 0:12:46Still to come, Chris helps to answer the UK's emergency calls...
0:12:46 > 0:12:49The most important thing we're worried about is a heart attack.
0:12:49 > 0:12:51We show you how to cope if this happens...
0:12:53 > 0:12:55You knocked my tooth out!
0:12:56 > 0:12:59And I take a lie detector test!
0:12:59 > 0:13:02I was recruited to be a spy while I was at university.
0:13:02 > 0:13:03OK.
0:13:04 > 0:13:06Remember Scott and his badly cut leg?
0:13:06 > 0:13:08Well, let's find out how he's getting on.
0:13:08 > 0:13:10And this is not for the squeamish!
0:13:10 > 0:13:11Wah!
0:13:14 > 0:13:18Back in Liverpool, Scott's been in overnight with an injured leg.
0:13:19 > 0:13:21Scott was on his mountain bike,
0:13:21 > 0:13:23having a wheelie competition with his mates.
0:13:23 > 0:13:25Erm, they're not wearing helmets.
0:13:25 > 0:13:28I know, Xand. Suddenly his foot slipped off the pedal.
0:13:28 > 0:13:29Oh, be careful!
0:13:29 > 0:13:31At first he thought it was just a scratch,
0:13:31 > 0:13:33but when he looked at it, he cried out.
0:13:33 > 0:13:34Ouch!
0:13:36 > 0:13:40It is hurting me, but it's a lot better from yesterday.
0:13:40 > 0:13:42It might not be as sore as it was,
0:13:42 > 0:13:46but Scott needs an operation to get that wound fixed up.
0:13:46 > 0:13:50So, it's in with the anaesthetic and off to sleep for Scott.
0:13:50 > 0:13:53Now it's surgery time. A few tweaks and...
0:13:53 > 0:13:56Let's give it a wash and see what we're dealing with.
0:13:58 > 0:14:00In the hot seat today, surgeon...
0:14:02 > 0:14:06First, Mr Badge needs to cut away all the dirty, contaminated tissue
0:14:06 > 0:14:08at the edge of the wound.
0:14:08 > 0:14:10He then gives the whole thing a right good clean
0:14:10 > 0:14:13to keep it free from infection and help it heal.
0:14:14 > 0:14:17Soon, it's time to start stitching.
0:14:17 > 0:14:20If you're squeamish, look away now!
0:14:20 > 0:14:22There, that's that.
0:14:22 > 0:14:23Great job, Doc. Very neat.
0:14:25 > 0:14:28It's rather fortunate that he didn't do any damage to the nerve
0:14:28 > 0:14:31and the blood vessel which is running down the back of his leg.
0:14:31 > 0:14:33He got away with a minor injury.
0:14:34 > 0:14:36Scott's soon up on his feet again,
0:14:36 > 0:14:39and keen to get back to his favourite hobby - boxing.
0:14:42 > 0:14:44- Bye, Scott!- Bye.
0:14:48 > 0:14:51It's not only emergency departments in hospital
0:14:51 > 0:14:52that deal with the unexpected.
0:14:52 > 0:14:53That's right, Chris.
0:14:53 > 0:14:57There are expert teams all over the UK, ready for action.
0:14:59 > 0:15:02We're on call with the UK emergency services.
0:15:02 > 0:15:03If you have an accident,
0:15:03 > 0:15:06an emergency service like this won't be far away.
0:15:11 > 0:15:14Paramedics use these state-of-the-art vehicles
0:15:14 > 0:15:16to get to emergencies in minutes.
0:15:16 > 0:15:17And today I'm going along to see
0:15:17 > 0:15:20what it's like to be the first at the scene.
0:15:21 > 0:15:23This fast medical service is on standby,
0:15:23 > 0:15:26ready to help 24 hours a day.
0:15:26 > 0:15:29Never know exactly what we're going to see when we get there,
0:15:29 > 0:15:33but I've got my camera and Eric in the back has got his,
0:15:33 > 0:15:37so we're going to get right up close and see what's happening.
0:15:37 > 0:15:39On call with me is...
0:15:41 > 0:15:43And a new case is just in.
0:15:45 > 0:15:49We've just got information - this is a 40-year-old woman.
0:15:49 > 0:15:51She's got chest, upper back pain.
0:15:51 > 0:15:55The most important thing we're worried about is a heart attack.
0:15:55 > 0:15:58Jan grabs her gear and gets inside.
0:15:58 > 0:16:00What's been happening, Tanya?
0:16:00 > 0:16:04Oh, gosh, I had gallstones removed. It's the same pain.
0:16:04 > 0:16:06- The same pain as what you had before?- The same pain.
0:16:06 > 0:16:08Let's give you some gas and air so we can try
0:16:08 > 0:16:09and get you a bit more comfy.
0:16:09 > 0:16:11Tanya's quite distressed,
0:16:11 > 0:16:14so Jan gives her some painkilling gas to help.
0:16:14 > 0:16:16It doesn't look like it's her heart,
0:16:16 > 0:16:18and it may be related to an old problem.
0:16:18 > 0:16:20So, Tanya's previously had gallstones,
0:16:20 > 0:16:23which are stones in a part of your body called the gall bladder.
0:16:23 > 0:16:27And the gall bladder secretes stuff into your gut that helps you digest
0:16:27 > 0:16:31food, and if it gets blocked with stones it can be intensely painful.
0:16:31 > 0:16:34The only difference is it's in my back and shoulders as well.
0:16:34 > 0:16:37So this time it feels a bit different to her gallstone pain,
0:16:37 > 0:16:41and the ECG confirms her heart is fine.
0:16:41 > 0:16:43There's an ambulance on its way, all right?
0:16:43 > 0:16:44But Tanya's going to need
0:16:44 > 0:16:46to get this new pain investigated in hospital.
0:16:46 > 0:16:48So while we're waiting for the ambulance to come,
0:16:48 > 0:16:50I'll try and get you comfy.
0:16:50 > 0:16:52And because she's in some discomfort,
0:16:52 > 0:16:56Jan decides to put painkillers directly into her bloodstream.
0:16:56 > 0:16:59Right, that should start having a bit of an effect soon.
0:16:59 > 0:17:02Finally, she's now able to make her own way out to the ambulance
0:17:02 > 0:17:04with her pain under control.
0:17:04 > 0:17:08So, Tanya's biggest problem was that she was in a huge amount of pain.
0:17:08 > 0:17:11Luckily, Jan showed up with some reassurance
0:17:11 > 0:17:12that it wasn't her heart.
0:17:12 > 0:17:14She's off to hospital,
0:17:14 > 0:17:17where they'll be able to get to the bottom of exactly what's going on.
0:17:17 > 0:17:21And if you ever have an emergency, there are hundreds of similar
0:17:21 > 0:17:24crews around the country, ready to help.
0:17:24 > 0:17:25If they can't fix you at the scene,
0:17:25 > 0:17:28they'll get you straight to a hospital for more treatment.
0:17:39 > 0:17:40So, look after those gnashers!
0:17:44 > 0:17:46I don't know about you,
0:17:46 > 0:17:48but Dr Xand goes absolutely stir-crazy
0:17:48 > 0:17:50if he can't get enough exercise.
0:17:50 > 0:17:51BIKE BELL RINGS
0:17:51 > 0:17:54Fortunately, it's possible to get exercise even if you don't
0:17:54 > 0:17:56have that much space.
0:17:56 > 0:17:57BIKE BELL RINGS
0:17:59 > 0:18:03But remember - even the back garden can be a place of danger!
0:18:07 > 0:18:10Well, I'm sure I don't have to point out what could go wrong here!
0:18:10 > 0:18:13I mean, Xand could fall and break his leg!
0:18:13 > 0:18:15I don't think so, Chris.
0:18:15 > 0:18:17Well, you might trip up and twist your ankle.
0:18:17 > 0:18:20No, it's not going to happen, Chris!
0:18:20 > 0:18:22Well, you could fall and just hurt your wrist.
0:18:22 > 0:18:25Chris, I'm really very good at this!
0:18:25 > 0:18:27Wah! Wah! Argh-uh!
0:18:27 > 0:18:28CRASH!
0:18:30 > 0:18:33Told you, Chris, I'm not injured at all.
0:18:33 > 0:18:35I am!
0:18:35 > 0:18:36You knocked my tooth out!
0:18:36 > 0:18:39Uh-oh! Looks like an injury alert!
0:19:02 > 0:19:04You guessed it, the answer is C...
0:19:07 > 0:19:08And here's how.
0:19:08 > 0:19:10Ah!
0:19:10 > 0:19:11My tooth!
0:19:11 > 0:19:14OK, so the first thing we've got to do is stop your mouth bleeding.
0:19:14 > 0:19:17- Mmm! - Does anyone have a cloth I can use?
0:19:17 > 0:19:18Dr Xand, I've got a cloth.
0:19:18 > 0:19:19Thank you very much.
0:19:19 > 0:19:23So, put it in the hole and apply pressure to stop the bleeding.
0:19:23 > 0:19:25Now we've stopped Dr Chris's mouth bleeding,
0:19:25 > 0:19:27we can pick up the tooth.
0:19:27 > 0:19:28Right there.
0:19:28 > 0:19:30If only I had a glass of milk to put it in.
0:19:30 > 0:19:33When you put the tooth in milk, it keeps the tooth alive.
0:19:33 > 0:19:37That means there's a better chance a dentist can put it back in.
0:19:37 > 0:19:39Now we've got the tooth safe in the milk,
0:19:39 > 0:19:40we can take Dr Chris to the dentist.
0:19:40 > 0:19:44Now remember, you only need to do this if it's an adult tooth.
0:19:44 > 0:19:48Time for this lot to have a go, with fake teeth as a prop.
0:19:48 > 0:19:50Oh, my tooth!
0:19:50 > 0:19:53Now remember, we're showing you what to do in an emergency.
0:19:53 > 0:19:58Never do this on your own unless it is. And always try and find an adult.
0:19:58 > 0:20:00Here's a cloth to stop the bleeding.
0:20:00 > 0:20:02Use it to apply pressure right on the hole.
0:20:02 > 0:20:07Now you need to find that tooth and put it in a glass of milk.
0:20:07 > 0:20:10Fortunately, I have a glass of milk right here.
0:20:10 > 0:20:11Well done, Jennifer.
0:20:13 > 0:20:15So, if you've lost a tooth, stop the bleeding,
0:20:15 > 0:20:17put the tooth in a glass of milk
0:20:17 > 0:20:19and get yourself to the dentist.
0:20:19 > 0:20:22But always try to find an adult first.
0:20:22 > 0:20:25- Do be careful up there, Chris. - Don't worry, Xand.
0:20:25 > 0:20:27I've got it...under...
0:20:27 > 0:20:28control!
0:20:28 > 0:20:29CRASH!
0:20:32 > 0:20:35No further harm done to me.
0:20:37 > 0:20:38Ouch.
0:20:44 > 0:20:45Xand?
0:20:45 > 0:20:46Who ate my cake?
0:20:46 > 0:20:48I don't know what cake you're talking about.
0:20:48 > 0:20:50It was gone when I got here.
0:20:50 > 0:20:52A bird, I think, ate it? Or a man.
0:20:52 > 0:20:53A birdman. A birdman ate it.
0:20:53 > 0:20:55Xand, if you're going to tell porkies
0:20:55 > 0:20:56you're going to have to learn
0:20:56 > 0:20:58to hide the evidence a bit better than that.
0:20:58 > 0:21:01On second thoughts, perhaps I can help you with this.
0:21:01 > 0:21:04- More cake?- No, Xand, time for Investigation Ouch!
0:21:07 > 0:21:09Come in, Dr Xand. Come in, Dr Xand.
0:21:09 > 0:21:11This is Dr Chris, over.
0:21:13 > 0:21:14Come in, Dr Xand, do you copy me?
0:21:14 > 0:21:16This is Dr Chris, over.
0:21:18 > 0:21:20Xand, it's Chris! Hey, I'm down here!
0:21:20 > 0:21:22Hello!
0:21:22 > 0:21:23Right, that's better.
0:21:23 > 0:21:26Now, I have a very special Operation Ouch mission for you.
0:21:26 > 0:21:30- OK. You want me to be like James Bond or something?- Exactly.
0:21:30 > 0:21:32You're going to be Operation Ouch Seven,
0:21:32 > 0:21:35and like all top spies you're going to have to go undercover
0:21:35 > 0:21:38and convince people that you're someone you're not.
0:21:38 > 0:21:41So basically you want me to lie?
0:21:41 > 0:21:42Yes.
0:21:42 > 0:21:43But these will be no ordinary lies,
0:21:43 > 0:21:47because you're going to be up against a new lie detector machine.
0:21:48 > 0:21:51I've sent Xand to the University of Bradford to see if he can
0:21:51 > 0:21:55hide the signs of lying from their snazzy new lie detector.
0:21:55 > 0:21:58OK, to be honest - it's not good to lie,
0:21:58 > 0:22:00but this is a scientific experiment.
0:22:01 > 0:22:03Xand's up against master of lies -
0:22:03 > 0:22:06but he doesn't ever tell one...
0:22:08 > 0:22:10The lie detector uses cameras
0:22:10 > 0:22:13to examine a person's face when they're talking.
0:22:13 > 0:22:16Because your body has certain mannerisms when you lie,
0:22:16 > 0:22:19the lie detector can tell by the faces you're pulling
0:22:19 > 0:22:21if you're telling the truth or not.
0:22:23 > 0:22:26I wonder if my body language will give me away?
0:22:26 > 0:22:29But first, they're recording my facial expressions to see how
0:22:29 > 0:22:31my body behaves when I'm being honest.
0:22:33 > 0:22:37So, Professor Hassan knows that everything I'm saying here is true.
0:22:37 > 0:22:39OK, Professor Hassan, I'm ready.
0:22:39 > 0:22:40What is your name?
0:22:40 > 0:22:42Alexander van Tulleken.
0:22:42 > 0:22:44What is your twin brother's name?
0:22:44 > 0:22:46Christopher van Tulleken.
0:22:46 > 0:22:48A few more honest answers, and that bit's over.
0:22:50 > 0:22:52The lie detector now knows
0:22:52 > 0:22:55what my face looks like when I'm being honest.
0:22:55 > 0:22:58Now I need to keep that same face even when I'm lying!
0:22:59 > 0:23:02From now on, Professor Hassan and his lie detector don't know
0:23:02 > 0:23:05whether I'm telling the truth or a lie.
0:23:05 > 0:23:06You'll know at home by these.
0:23:08 > 0:23:12Let's see if I can fool the lie detector with my fake honest face.
0:23:12 > 0:23:14I can speak five languages.
0:23:14 > 0:23:15Excusez-moi, monsieur?
0:23:15 > 0:23:17Wah!
0:23:17 > 0:23:18OK.
0:23:18 > 0:23:21I worked in a pet shop selling dog collars.
0:23:22 > 0:23:23OK.
0:23:23 > 0:23:26I was recruited to be a spy while I was at university.
0:23:31 > 0:23:32Right.
0:23:32 > 0:23:33I did rowing, like I rowed in a boat.
0:23:35 > 0:23:36OK.
0:23:36 > 0:23:38I like to do ballet dancing.
0:23:41 > 0:23:43OK.
0:23:43 > 0:23:44I've travelled to lots of countries.
0:23:46 > 0:23:48Thank you.
0:23:48 > 0:23:49Well, that wasn't too bad!
0:23:49 > 0:23:51I think I fooled him.
0:23:51 > 0:23:52We've got the results here.
0:23:52 > 0:23:55We actually believe that you lied quite a bit
0:23:55 > 0:23:57in the interrogation questions.
0:23:57 > 0:24:00Our results show that you actually lied about 50%.
0:24:00 > 0:24:01That's exactly right.
0:24:03 > 0:24:06The lie detector knows I lied on half of my answers.
0:24:06 > 0:24:08So what gave me away?
0:24:08 > 0:24:11We saw a little twitch on your forehead here.
0:24:13 > 0:24:15- You had a high blink rate.- OK.- Yes.
0:24:17 > 0:24:20We had seen your nostril dilate quite a bit.
0:24:20 > 0:24:22- When I'm lying? - When you were lying, yes.
0:24:24 > 0:24:28- So a new facial expression means a lie?- Yes.
0:24:28 > 0:24:31This sounds like it was quite easy for you to do.
0:24:31 > 0:24:34Yes, it wasn't too difficult, really, to be honest.
0:24:34 > 0:24:35I thought I was doing a really good job.
0:24:35 > 0:24:37I thought I really had you fooled.
0:24:37 > 0:24:38I don't think you are a very good liar.
0:24:39 > 0:24:42Actually, I take that as a compliment, Dr Hassan.
0:24:42 > 0:24:45Lying isn't a good idea, not least because your facial expressions,
0:24:45 > 0:24:49even your mannerisms, change every time you lie.
0:24:49 > 0:24:52You might not realise it, but things happen
0:24:52 > 0:24:55that you have no control over every time you tell a porkie.
0:24:59 > 0:25:02Let's head back to accident and emergency.
0:25:02 > 0:25:03For another curious case!
0:25:07 > 0:25:09In Liverpool accident and emergency,
0:25:09 > 0:25:1211-year-old Daisy is in with a sore tummy.
0:25:12 > 0:25:14I can't stand up properly cos it makes me
0:25:14 > 0:25:18feel as if I'm going to faint, and it makes me really dizzy.
0:25:19 > 0:25:21Right, let's find out how all this started.
0:25:22 > 0:25:23TUMMY GURGLES
0:25:23 > 0:25:26- Daisy's tummy was feeling funny. - Ha-ha-ha!
0:25:26 > 0:25:28Was it telling jokes, Chris?
0:25:28 > 0:25:30- Did you hear the one about the... - No, Xand -
0:25:30 > 0:25:32it was actually quite grumpy and sore.
0:25:32 > 0:25:34Gwah-ha-ha-ha!
0:25:34 > 0:25:37She wasn't able to go to school...
0:25:37 > 0:25:39she wasn't able to do her gymnastics...
0:25:39 > 0:25:43and at Mum's farm, Daisy couldn't ride her favourite horse.
0:25:43 > 0:25:45Neigh, why not?
0:25:45 > 0:25:49Every time the horse jumped, Daisy's tummy gave her a thump.
0:25:49 > 0:25:50Ouch!
0:25:51 > 0:25:53This is Shakira.
0:25:53 > 0:25:55Oh, nice coat!
0:25:55 > 0:25:58I want to get better so I can ride the horses again.
0:26:01 > 0:26:03Here to help get her back in the saddle is...
0:26:05 > 0:26:08It feels like someone's pushing down on my belly.
0:26:08 > 0:26:11There are lots of things that can cause your tummy to hurt,
0:26:11 > 0:26:14like a urinary infection, or even appendicitis.
0:26:14 > 0:26:17I examined her tummy just to make sure it felt normal,
0:26:17 > 0:26:19that it wasn't too painful all over,
0:26:19 > 0:26:22and to try and find out where the pain was coming from.
0:26:23 > 0:26:26To help find out, the doc has ordered some blood tests
0:26:26 > 0:26:29to check up on Daisy's internal organs.
0:26:29 > 0:26:30Good girl. Well done!
0:26:30 > 0:26:32While her samples are processed at the lab,
0:26:32 > 0:26:36Daisy's on her way to have another test.
0:26:36 > 0:26:40It's an ultrasound, which takes pictures of Daisy's internal organs,
0:26:40 > 0:26:42and checks they're all OK.
0:26:42 > 0:26:43- Right, so you are all done! - Thank you.
0:26:43 > 0:26:45Meanwhile, at the bloods lab,
0:26:45 > 0:26:47Daisy's results have just come through.
0:26:49 > 0:26:51So, what's the verdict?
0:26:51 > 0:26:53The good news is the ultrasound scan was absolutely normal,
0:26:53 > 0:26:56- and all her bloods are absolutely normal, OK?- Yay!
0:26:56 > 0:26:59Wait a minute, why does she have a sore tum?
0:26:59 > 0:27:03Sometimes kids get abdominal pain and we can't find a cause for it.
0:27:03 > 0:27:06And normally it just settles down on its own.
0:27:06 > 0:27:09But Daisy will need to get lots of rest to get back to normal.
0:27:09 > 0:27:12I'm going to lie on the couch for a little bit
0:27:12 > 0:27:15and then feed my guinea pigs. And my mum can feed the dogs.
0:27:15 > 0:27:17OK, I'll feed the dogs.
0:27:17 > 0:27:21Well, that's that agreed, then. All's well that ends well.
0:27:21 > 0:27:22Bye, Daisy!
0:27:22 > 0:27:24Next time on Operation Ouch...
0:27:24 > 0:27:27We put Xand's body bacteria to good use...
0:27:27 > 0:27:28Urgh!
0:27:28 > 0:27:32That's the nastiest cheese I have ever smelled!
0:27:32 > 0:27:34I'm on an emergency call...
0:27:35 > 0:27:39We're going to see someone who's got a very severe cut on the head.
0:27:40 > 0:27:42And I meet a man with a bionic eye.
0:27:42 > 0:27:45He could see something for the first time in years.
0:27:46 > 0:27:48So that's it, till next time from Opera...
0:27:48 > 0:27:49Operation Ouch!
0:27:54 > 0:27:55- LAUGHING - Fortunately,
0:27:55 > 0:27:56it's possible to get exercise
0:27:56 > 0:27:59even if you don't have that much space.
0:27:59 > 0:28:02If it was a person it would be in trouble!
0:28:05 > 0:28:07I don't have handles!
