because this orchestra called the brain continuously adopts itself. and so we ask a few astute questions. we can control our thoughts, which makes us very power, kind of like a superpower. questions about life, the universe? our series, 42 years, almost everything. this week on t w ah, unsafe handling of fireworks can cause devastating injuries to your hands in just a fraction of a 2nd. cat bytes can also inflict serious injury some jobs compose a threat to a 5 digits to have consist of both. but did you know that smartphones can also damage your hands?

that's your exercise to keep fit. but have you ever done a workout for your fingers? today will show you some simple but effective exercise. healthy hand. this week's topic on in good shape. the d. w. health a our hands are the epitome of human creativity. most tools are made by and for our hands, and our hands themselves are complex tools which evolved over millennia. there are 27 bones in the human hand, more than any other part of the body. and its muscles are very complex, more than 30 muscles, move the hand and fingers. the muscles in the hand can spread your fingers and the

muscles that extend into the forearm allow you to grasp and open your fingers. and our finger tips are densely packed with thousands of nerve endings that makes them highly sensitive to touch. a lot of brain power is needed to process all these nerve impulses and control muscle movements in the brain, sensory and motor cortex. the areas associated with your hands are especially large that allows us to carry out very complex hand movements. another part of the brain plays a role in coordinating and fine tuning those movements. the cerebellum. the cerebellum has more than half the neurons in your brain and constantly makes fine adjustments to motor movements. that's why once we've learned a complex motor skills, like riding a bike, we can do it again and again, without giving it all too much thought. and there's more the left hemisphere of the

brain controls the right hand. and the left hand is controlled by the right hemisphere. in most people, the right hand is dominant, as is the left hemisphere. so parts of the left hemisphere are slightly larger, especially the motor cortex. so is it exactly the other way around for a left handed people surprisingly know in many left handed people, the left hemisphere is dominic, just like in right handers. and often neither hemisphere is clearly dominant which hand we prefer is probably determined mainly by our genes. but in many cases, what matters most is how will our hands work together. ah, and for that, both hemispheres of the brain need to communicate that happens in the corpus callosum a thick bundle of nerves that can next the 2 hemispheres. and thanks to brain

plasticity, repetition and practice help form new neural connections. so practicing new skills with your hands will also keep your brain sharp and nimble. there are many different hand exercises. jim and physiotherapists often recommend the following work out to strengthen your muscles and ligaments. fast. blend your elbows and bring your hands up in front of you. clenching them into tight fists for a few seconds. then press your finger tips firmly against your palms. repeat 5 times, exercise to stretch your arms and fingers out in front of you. drop your wrists down. now hold a strong fist for 10 seconds. exercise 3, extend your arms, palms facing up now till 2 hands down 90 degrees just enough so it doesn't hurt. hold for 5 seconds and repeat 10 times. and lastly,

hold your pons up towards you. slowly sweep your thumb like windshield wipers towards your little fingers and back. holding briefly each time. this was how can god against repetitive strain injuries, typing swiping and scrolling in that digital age al sums are exposed to a lot of strain disk, a need to what's known as smartphone thumb, or whatsapp pidas us to pursue comcast. the typical symptom is increasing inflammation. attendance from the thumb, lemon as we normally only see this at age 15 um official documents, but now young people are developing these kinds of complaints. but don't have any other obvious cause. a pain in the thumb join till hand is assign of over use or wear and tear on the joints. usually it's the tendons

sheet that becomes inflamed. when brenda stocker rides in this kind of irritation or over use the causes the sheets surrounding attendant to thicken. then attendant doesn't have enough room to slide freely and as she are, the result is what people call tendonitis. i'm cold packs. massage physiotherapy and can easy ology type can help. but sometimes the problem is more serious. pretty similar to what you end up with is chronic irritation or inflammation of the tendency of. uh huh. that's what the treatments try to address for the 1st of all, ensuring that the thumb gets rest. i think a lot of times that solves the problems. then there's cortisone therapy, and last of all, surgery women, sometimes the only thing that helps are surgical removal of the inflamed tissue. so it's best not to get smartphone thumb in the 1st place. experts recommend operating

your mobile with both thumb, so you don't overstretched. the joints using your index finger instead can help to is really a bag of mine. as the father of a 17 year old daughter, i'd say set the cell phone aside more often impose some reasonable limits that can benefit other aspects of life as well. what i'm doing is lead the best way to prevent what's up i to us giving your smartphone and your thumb a break. expose is great for our health, but it's not without risk. humble is one of the riskiest bullets. we'll your hands, the fast moving bull can injure your fingers. the interaction between players can also be dangerous. the close contact tackling can lead to torn tendons and broken bones. is also risk of falling heavily. hand surgeons deal with sports injuries every a. treating

a dislocated wrist can be particularly problematic. it's hot and liam does this. i love flying more than anything, and i've been playing the piano since i was a girl. so my 1st thought was, what will happen to those 2 things? i love light and shuffle pass, young pilot, loud cometh, dislocated joint in both wrists in the fall to dislocated joint found like it would be easy to fix. and i was quoted as high in a dislocated risk, which is usually the wrist is also broken. and there are torn ligaments isn't all of that needs to be realigned in repairing those joins requires very precise and complex surgery at la comma had a serious injury, which was clearly visible on the x ray. yet of more by why this is the loony bone. it's called that because it's crescent shape elephant on the mine. it's popped out

of its normal position. the on the other bones are still in the correct position, but they're no longer a functional unit. because these carpal bones and the ligaments form a unit, a nun, if one bond pops out and the, the ligaments are affected, all is loosed, and the rest becomes unstable at the sound, getting things to be. when her ambulance arrived at the trauma center, she was no longer conscious. what do you remember about the accident? it shunt? i'm feeling like that of i was in line waiting for a climbing wall. it was busy, so i figured i'd try a different one. i started climbing and just forgot to secure myself. but luckily i didn't climb all the way to the tom about some company that would have been over 6 meters. i let go after 3 or 4 meters on a right. before i hit the ground, i realized i wasn't secured. so i automatically reached out and fell on my hands. it was the worst pain i'd ever felt in my life. as i was lying that people came

over and told me to lie still and raised my leg side hymns with what they called an ambulance. it took 10 minutes to arrive, but felt like forever. but when the paramedics came, i asked them right away to give me something to knock me out because the pain was unbearable. the fish laugh is her dish mouth. michelle's. later that night she underwent surgery on both hands. a dislocated rest is an emergency plated for mine, and 1st of all and was swelling can be severe from on and 2nd point because of the anatomy of the wrist. the median nervous compressed, which leads to carpal tunnel syndrome. pike livable and all the little wrist bones need to be reconnected in football. while avoiding any scoring i could limit range of motion because of that. so the bones need to be put back into position. and any ligaments that were damaged or need to be surgically repaired to leave a little to the something you didn't even kind of low her crime as is

a pilot. but it's unclear whether she'll ever be in the cockpit. again, i look, that's yolanda for patients, dislocations of illuminate bowl or take a long time to heal and often result in some level of disability with your climbed i in shinkel, the my, my marital angled saw. my i moved in with my parents until my mother. i'm like a baby again. you have to wash me. feed me, do everything i can't day right now. this moment miss come. after surgery, she started working with the physical therapist, vanessa diesel, pretty soon lava was making amazing progress. in 6 months after the accident and surgery, dr. here, she was surprised at her wrist nobility. yamisha as that you have almost 70 degrees

here, which is a lot much liking. but now here raises please. from here, that's almost 60 degrees. so great coin went up. now been forward, 45 degrees, this is also a very good range of motion. many people have age, 90 degrees of extension, 180 to 90 degrees of collection label and practice. so you only need around $30.00 to $40.00 degrees in each direction, not polished. wow. mom on lava also has some good news to northwest and you live on the 2nd of july, i passed the pilot's medical exam. very nice up for her before that i had to test if i was really up to it. i did a test flight in a simulator and the instructor gave me the green light speed i got selected as it can go. then i started the re qualification process with you and started flying again on the 9th of july and everything feels back to normal things evolved final. that's great. it's a really phenomenal outcome and i am back out on sunday night when i flew back from

my holiday as a passenger, i said, i'll be so happy to be in the cockpit again. more than 55000000 people worldwide have suffered the amputation of a limb due to traumatic causes. prostheses can restore independence and sometimes even enable incredible achievements. paralympic athletes with press theses now perform as well as their olympic peers without prostheses. and the latest prosthetic hands are even capable of learning thanks to a ali. this robotic hand can learn to cooperate with its wearer. thanks to artificial intelligence. was gang balla is its teacher and also its own up to dave of gang bower can use his robotic arm to carry out amazingly precise and fluid movements. for him,

the i based technology has opened up a new realm of possibilities. the thing to me further about, i don't have to think about what i want my robot arm to deal with. he does it just does it automatically compare the message voice gang is a farmer tending to his crops and livestock is all he's ever wanted to do. but then he had an accident involving a crop chop her blade his lower arm had to be amputated all to continue farming. he needed a prosthesis that would replace his hand at a german prosthesis. manufacturer, physical therapist, done yellow views to fail to teach his patients how to use their a i base to robotic limbs. with the initial training process takes

several weeks. this specially designed cuff is fitted with 8 pairs of electrodes. they recognize tiny movements in the muscles of the upper arm. an app visualize is these tiny movements and stores them as movement patterns. as crypt unblocked her been on the cover and out are connected by bluetooth lemon shutters and can fly the current. there are lots of electrodes and 0. these tiny impulses involve guns, muscles will be transferred onto the out, but on my work, gosh, that fin, especially voice gang, is learning how to use his robotic hand. it's crucial that the tiny muscle impulses he's learning are as distinct as possible at that way. the prosthesis can link each impulse to a specific movement. he's not starting from scratch, even after an amputation. the brain remembers the patterns of movement needed to do things like open or close at hand. once muscle impulses become associated with

specific movements, the robotic lem, we'll use artificial intelligence to learn specific movement patterns. the electrodes inside the robotic lim, register the muscle impulses from the upper arm. the app matches these muscular patterns to specific movements and stores them. while voice gang bowers spent weeks learning the basics, the company's engineers were building his robotic lim. now it's ready to learn and adapt to voice gang bowers movement patterns. his robotic lim has brought him a major increase in quality of life. begin in his trowing movements is just amazing room. all you have to do is imagine opening your hand and the robot hand opens, taylor imagined closing in it, and it closes it same with rotating either the prosthetic arm just doesn't. everything was as with many things, practice makes perfect. that's the only way the intelligent prosthesis can continue

learning, including therapy, the cough and fine tuning, the devices cost around $60000.00 euros. and ms. ellis, i would, honestly, i can't imagine my life without those pers thesis. i use it all day long, depending on what i'm currently doing because it doesn't, i use the pers thesis for everyday purposes at home to, for things like eating somebody. there's so many things i use it for it with his it . thanks to his prosthetic hand, voskus, bella can continue to follow his dream. our hands are not only brilliant useful. they something that others judge us on. after all, at some point, those around us usually noticed them and nibbled down nails or rough skin can send an unintended message. plus our hands often age quickie to betraying us with wrinkles and age spots. that's because, unlike other parts of our bodies, they're exposed to a lot of light,

dermatologists recommend applying sunscreen to your hands all year round. and even if you don't consider such things, especially important, it's still good to give your hands a bit of tea. i'll see. many people suffer from dry hands, especially in the winter. what can health barbara beer is a pharmacist who's familiar with the causes of dry skin asking for she noticed there are several factor huffman. some, 1st of all, your hands don't have as many, spacious glasgow as well, and the skin there is quite good that in as a result, the skins acid metal barrier might be compromised. that makes the skin more vulnerable to bacterial and viral infections. people who work with solvents and other chemicals often suffer from dry skin. during the kobe pandemic, alcohol based hand sanitizers became part of daily life. but they're also bad for your skin disinfect. so you can picture how disinfected work by imagining accuracy

kind of. and when you add dishwashing liquid to the pan, you dissolve the fat out of the lippitt. that's what solvents and disinfectants do . they dissolve the lip, it's on your skin, him under thunder. so when you wash your hands, you're rinsing the natural oils off your skin. it out to how it hand creams are designed to restore this protective barrier and keep your skin soft and smooth, which is especially helpful if you use hand sanitizers less. anc liam there. that madeline. i generally recommend that people put cream on their hands. first thing in the morning to get that protection, and i am done with that also helps keep the lippard barrier intact. when you wash and disinfect your hand, them as it might be. and if you can put cream on your hands throughout the day in my mavita you but intact and dec dnd the anchor him there are all sorts of hydrating hand creams on the market. many contain ingredients like urea, high electronic acid for lin, aliya acids. again that i give this kind of path to the perfect skin,

cream or lotion doesn't really exist. sites from the cranes should contain waste risers, as well as fat from the side, but beds in the again, we also generally advise people these records re creams that are ph balance out more ties. and nowadays, there are also lotions that contain sanitizers, a to, and one solution. my kindness of unifying my hand, sanitizer motions are quick and easy, but we generally advise against frequent use because it can disrupt the skin micro biome, hydrogen. i'm nothing can if you don't like the feel of a greasy film on your skin, choose creams and motions that don't have too much oil, and no mineral oils or petroleum jelly. they absorb much more quickly. the pharmacist also recommends hand baths with oils drinking enough water is also key to make sure you're not dehydrated, and it's best to use liquid. so rather than bar. so because liquid soap spreads more easily, there's also a trick to applying lotion as m, f, as in law,

and as we recommend hazelnut eyes, dawn up to the back of your hand, king. and on the i then rubbed the back of your hands together and rub forward to your fingertips, seen batteries. so that way your palms don't get to greasy, which is nice if you're working or hold to his smartphone had been months, much bad. smartphone was when it's cold outside gloves are a good idea to help prevent dry chopped hands in the winter. ah, do you love gardening, or play an instrument like this trend is probably not for you. long chic fingernails in every color imaginable. and a hash tag nails, instagram alone boasts almost 200000000 posts on nail head. we have the auto industry to thank for the availability of dazzling and above all durable nail enamels. it's not yet clear where the car pains are entirely harmless when applied directly to the body. but as we open touch our faces,

unexplained redness could actually be a hyper sensitive reaction to our nail polish. nonetheless, polish can cover up unsightly blemishes on our nails. like white spots, for example, trimming, shaping and polishing. many people spend a lot of time caring for their nails. as the saying goes, your nails complete the look. so you want them to be immaculate. but what about those white spots that looked like little clouds? where did those white spots come from? could they be a sign of a nutritional deficiency like calcium, or even a sign of something serious? it's true, your fingernails can be very revealing. do you bite your nails or smoke or do

a lot of cleaning? lots of exposure to water can make nails brittle, but white spots don't indicate an ion, biotin, or calcium deficiency, or any kind of illness. those little white clouds come from somewhere else entirely. our nails are made of more than $100.00 layers of nail cells which come together in the matrix and grow to form the nail plates. sometimes tiny apple kits formed between the layers and they look like little white spots. usually that's caused by small bumps to the nail, even a manicure can be the culprit, especially if the cuticles have pushed back to vigorously o trims. so those white spots on to problem when it comes to nail care,

sometimes less is more. and if you still end up with white spots, you can always reach for the nail polish for oh, beautiful thing. and else are of course not enough on their own. that's why it's time for a full body work out here a full quick exercises with hi and welcome. today we're gonna do a whole office work out for different exercises. 30 seconds long, so only 2 minutes. and i think you have those 2 minutes. are you ready? let's go. then his wife, left your knee and touch your elbow. it's important that you back this straight and just move. he also can get faster if you want up
