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 40 to the answer to almost everything this week on the w unsafe handing of fi works can cause devastating injuries to your hands in just a fraction of a 2nd. cat bites can also inflict serious injury some jobs compose the threat to a 5 digit to us consists 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 think is, today will show you some simple but effective exercise and healthy hand. this week's topic on in good shape. the d. w. health with 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 fingertips 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 skill, 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 left handed people? surprisingly know, in many left handed people love left hemisphere is dominant, 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 connects the 2 hemispheres. and thanks to brain plasticity, repetition and practice help for new neural connections. so practicing new skills

with your hands will also keep your brain sharp and nimble. there are many different hand exercises. german 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 upon repeat 5 tullocks. exercise to stretcher, arms and fingers out in front of you. drop your wrists down. now hold a strong fist full 10 seconds. exercise 3, extend your arms, palms facing up now till 2 hands down 90 degrees just enough so it doesn't hurt to hold for 5 seconds and repeat 10 times. and lastly, hold your palms up towards you. slowly sweep your thumbs like windshield wipers

towards your little fingers and back, holding briefly each time. this work, how can god against repetitive strain, injuries, typing swiping and scrolling in the digital age, al sums are exposed to a lot of strain. this can need to what's known as smartphone thumb or whatsapp vitus jupiter, comcast. the typical symptom is increasing inflammation. attendance and the thumb. lemon has normally only see this at age 15 um official document, 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 a sign of over use or wear and tear on the joints. usually it's the tendons sheath that become inflamed. ones, bene, stocks, right?

so this kind of irritation or over use causes the sheets surrounding attendant to thicken. then the attendant doesn't have enough room to slide freely and as she are, the result is what people call tendonitis. i get a cold packs massage physiotherapy and can easy. ology type can help, but sometimes the problem is more serious. pretty zebra. what you end up with is chronic irritation or inflammation of the tendency of. uh huh. that's what the treatments try to address the phone or the 1st of all, ensuring that the thumb gets rest. i think a lot of times that solves the problems. then there's cornerstone therapy and last of all surgery. sometimes the only thing that helps is 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

it's really a bag of mine. as the father of a 17 year old daughter, i'd say set the cellphone aside. more often impose some reasonable limits that can benefit other aspects of life as well. let me think of what i'm doing. the best way to prevent what's up i to say giving your smartphone and your thumb a break. expose is great for our health, but it's not without risk. campbell is one of the riskiest sports where 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 day. tweeting a dislocated wrist can be particularly problematic. is hutton liam does is 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 with us. young pilot lava cometh dislocated a joint in both wrists in the fall to dislocated joint. felt like it would be easy to fix. and alice cooper is in a dislocated risk, which is usually the risk is also broken. hm. and there are torn ligaments, isn't all of that needs to be realigned in repairing those joins requires very precise and complex surgery. la cometh had a serious injury, which was clearly visible on the x ray. you'd have more fun why this is the loony bone. it's called that because it's crescent shape elephant on a 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, won't be, the ligaments are affected. all of this 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 phoenix that of i was in line waiting for a climbing wool. 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. when i 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 there, people came over and told me to lie still and raised my leg side hymns before 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 hold his mouth. michelle's. later that night she underwent surgery on both hands. a dislocated rest is an emergency like mine and 1st of all and was swelling can be severe from on. and 2nd, of course, because of the anatomy of the wrist, the median nervous compressed, which leads to carpal tunnel syndrome proposal isn't all. and all the little wrist bones need to be reconnected in purple while avoiding any scoring i could limit range of motion. so the bones need to be put back into position and any ligaments that were damaged or need to be surgically repaired. and so we decided to send something it again, even kind of low huck. imus is a pilot, but it's unclear whether she'll ever be in the cockpit again. and i looked at

yolanda for patients, dislocations of the loony bowler take a long time to heal, and often result in some level of disability with your plan. dian shinkel. it's been 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. ringback moments which come after surgery, she started working with the physical therapists. vanessa diesel pretty soon lava was making amazing 6 months after the accident and surgery. dr. here, she was surprised at her risk nobility. yamisha trusted. you have almost 70 degrees here, which is a lot better now here. raise it please. so 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. one, many people have age 90 degrees of extension in 80 to 90 degrees of collection label and practice though you only need around 30 to 40 degrees in each direction, not published. wow. mom on the lava also had some good news to northwest. 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 could select it as it kind of the bubble sheet. 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 panel. and that's great. it's a really phenomenal outcome. and i am von 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. chris theses can restore independence and sometimes even enable incredible achievements. paralympic athletes with prostheses now perform as well as their olympic piers 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. ah, was gang bella, is its teacher, and also its own. up to dave king. bower can use his robotic arm to carry out amazingly precise and fluid movements for him. the a i base technology has opened up a new realm of possibilities. it didn't really credible. i don't have to think

about what i want my robot arm to do liberty. is it just does it automatically context of 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. 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 based robotic limbs. with the initial training process takes several weeks. this specially designed cuff is fitted with 8 pairs of electrodes.

they recognise tiny movements in the muscles of the upper arm. an app visualizes 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 20 impulses involve guns, muscles will be transferred onto the outbound number of crushed him. the firstly 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 in the upper arm. the app matches these muscular patterns to specific movements and stores them. while voice gang bower 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. but in his drawings, movements is just amazing room. all you have to do is imagine opening your hand and the robot hand opens taylor imagine closing in it and it closes it same with rotating either the prosthetic arm just doesn't ring. well. 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. in anything. what 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 my this. there's so many things i use it for his it thanks to his prosthetic hand voice gang, 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

drown 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,
