as he's got issues with a lot say, what crazy. the newborns don't yet have control over their muscles. but nothing works without done from keeping our heads up to crawling. for walking, the once we've learned to control, we often forget the hard pass we took to get there. many other organs rely on our muscles as well. how did they work? what are they made up of, and how do we keep them healthy? that's our topic today. on in good shape the

how life goes. sometimes some people are celebrated while others do the real work behind the scenes and all these, it's all muscles that do the heavy lifting. i leave with that. how can the heart come plod the lungs require and the digestive system process? food goals must have control of facial expressions. they allow us to claim can smile and they can make all has thumbs on. and i'm thanks to powerful scholarly to muscles. we can move our entire body and all kinds of objects. muscles are made up of bundles of muscle fibers. and these fibers consist of what the cool myers 5 rolls and these my of 5 burrows into a made up of proteins like mice and, and actin. and they was like tiny montez,

the best trick is by electrical signals that the transmitted threes, another system, the headset, the mice and proteins bind to the accent and move it along. the muscle begins to contract and because several waste several 1000000 of these missile muscle mates who's working together, it creates points to force. unlike machines, all muscles tend to mediately fail when subjected to too much strain. quite the opposite mind at damage to the 5 s is we're passed a new myers 5. both strands are even formed in the price. the muscles grow bigger and stronger as a result and that's good for all health muscle training. also strengthens binds and joints keeps the metabolism going to prevents muscle often old age the muscles can be trained in a targeted minor. however, that's because molten hoff it's done because control consciously and many organs,

the muscles that primarily control unconsciously quite the alternate make novice system. so the vital both of these functions always remain active. these muscles do also benefit from exercise indirectly. for example, sauce to plug flight trains, the house and blood vessels, deep breathing trains, the muscles of the respiratory system the muscles keep the show on the right. so they just pull the price, they can get the more than 100 years ago. muscle men flaunted their enormous pecks in the circus. in the 1950s body building grew in popularity. these days, muscle man or even in politics and muscle training isn't always in the gym. it looks as hitler's step behind the scenes. there's

a lot of strength and body control going on. slogan, pool has been bouncing valley since he was little here at the jo, noisy maya, thought a school and how big the tod on his body every day, especially his muscles and just as long as he to a certain amount of musculature to make it all lucky easy to control it all, it is to control it in he's being done single, his life and is very sick. and that could be because of his muscles. the research has have found that when our muscles work, they release whole names that are good for our bodies. good maya kinds during many different types of maya kinds, some of which helped to find information and rheumatism. another include muscular and it's important for the hot well data hodge is also in muscle, a comp which is muscogee in itself and depends on the other muscles to produce such

a new study shows that if the hot gets to initial my skin, it becomes weekend and less than lastic, that's the vehicle off the show you to go for a number of years then exercise as a physical activity is beneficial for hard problems. this stuff. but what we didn't know is that the muscle actually functions as a hormone gland, and releases most glenn, that's mostly 500. in particular, we had no idea how exactly must win affects the heart via that's why x bets recommend exercising the whole body. especially when the heart is weak activities, as if you do end up with it varies greatly from person to person and it will never be possible to make a body builder out of someone really skinny, especially if the person has heart problems, seek this stuff in the past the advice for patients with hard problems was that they should move as little as possible. that's how it took that advice changed years ago. they should in fact exercise and train their muscle salma most for

strength and endurance. and with that, the heart will improve help. it's of course it's beneficial. so people with healthy hearts to what was a p to stall as a bus man wants to encourage everyone to exercise as our school not paying those. cuz it's a really important that anyone can start exercising at any age in mind and they will always feel a positive effect on not only physically, but also mental. lately. for a long time moderates and your insights of science was considered sufficient for the experts. now i agree, it's important to train muscle strength to reach the positive effects of maya kind most in most group i'm a you have to really put strain on the muscle. and you should do that something like twice a week for the loading it to the point where it gets exhausted is an issue. and i'm suppose that has a much higher impact then continuous endurance training tool because i'm not sure

it's often by the impact is especially clear in terms of for example, does ease of the gastro intestinal try. and in terms of diabetes, high blood pressure and depression of allstate policy, or you can get maya kinds and tablet phone, well can use a good starch, but not enough flow here and to strength training twice a week off the rule, he doesn't just have to dawn it's perfectly invalid, but lift his partner at the same time. the keys started john sing when he was 11 and got one of the coveted places that the valet boarding school. now he's 33. he won't be able to dance forever, so he has to change career. at some point. he's studying alongside dancing and wants to become a fitness coach and pass on his knowledge. kind of like some would you be and just

the motivating people getting the best out. i thought we all these days, a lot of older people are also doing more exercise to maintain their independence in old age so that they don't have to rely and help from others. so that's really where i think i'm going to find my way to motivate people. mine fixed these large, it's somebody the walking out and studying are a good combination. even like exercise gets the brain going and increases performance by with mr. fish. nissan few generally found to learn a lot, having probably experience that you study something and if you exercise afterwards, it's easier to memorize things. and that's actually due to these mile kinds as well . the effects on the brain continues into old age. for example, studies show that muscles reduce the risk of dementia and double life expectancy for people with parkinson's disease. the muscles also help in

a very practical way. exercise will help to prevent julian from developing varicose veins. they usually appear when the veins no longer managed to transport blood out from the legs and the veins polish out the next, a strong muscle support the veins functioning like a pump and pushing the plot towards the hot and maya kinds can also benefit the blood vessels as it is supposedly tv effective, the 1st positive effect from the my okay, is that the inner vessel wall improve significantly fewer plaques, kennedy deposit that is the 2nd to fact is that it leads to end. your genesis include this means that more blood vessels are formed and the organs are better supplied with blood flowing through this improvement. so you can have a positive effect on 2 basic illness, listening strokes and even heart attacks on 5. what often happens intact,

best man is convinced of the importance of muscles and even prescribes muscle building 3 physio therapy, guessing into walking out can be difficult for anyone, as sylvia knows all too well a v a have eat us. yeah. and as i'm a positive one sex every year, we have a 6 week summer break. and when i was younger, i taught them great and did nothing for 6 weeks on. but i guess as you get older, you can feel that your body just needs a little bit more exercise. so how much of it? so now i started to do sports $2.00 and $3.00 times a week. so that when the season starts again, i'm really in top shape and don't need a week or 2 weeks to get back in the right side of well, this is fine. cover. all muscles want to grow and be exercised. and doing so helps fight cardiovascular disease. parkinson's out sinus infections and even varicose veins. slowly on it's clear she wants to keep doing regular exercise for the rest of his life. and especially keep on dancing.

the exercise is fun and keeps you fit well into old age. but what is the aging process and what happens in the body? the, the agent, your football, the begins ali, even if we don't notice it from around the age of 20, the long's taken less and with it less oxygen. the most common a slightly decreases. and from the mid twenties, the brain's metabolism also starts to change. this is the reason why we action times start to deteriorate the about the spinal disks begin to lose that unless this a t because they can no longer hold as much water off. all the becomes

more difficult to move the whole site by the age of 30, all millions of reach the maximum strength to maintain by mouth sufficient exercises that especially important the without exercise. the cardiovascular system can begin to decline as early as the mid thirty's. because the hot pumps less efficiently and the vessels are less elastic under exhaustion, these signs of aging become even more noticeable. but some thoughts about bodies can stay fit into old age. like how memory it can still function while it takes a and a good thing too, because every quotes the richness of our lives, the

research has shown that the brain can continue to change well into old age. but can we actively train it? said that mental exercises protect against dementia, but what is the science that there is no data to support that doing any of these protects your brain from developing all timers. so what you want to do instead learn a new thing. every time you learn something new, you are creating new neural connections. this is your brain getting bigger. your connections can also break down with severe consequences. mine eclipse the i guess the fear is that i'm not or won't be who i used to be this month. and i always great up, i always present. what did i want? the mission of features worried. she keeps me guessing what he was wanting to do just a few moments ago. don't believe it just now, for example,

he and his wife were discussing that sketch relate to breakfast and he realized he needed his glasses. that was why he recently retired from his jump into the bank and has lots of plans the future. yeah. for some time he and his wife to his moments of forgetfulness went on lunch. mindful then he develops new memory problems. he's only 60 the can no longer remember numbers. so password you can find exponent of us kind. i wanted to write something down shop and i went to do with him when called but i couldn't write the sentence which i haven't seen. so i'm not even one word this this me, i was gone. big smell like it was deleted, just like i never had it when dismay of forgetfulness become a disease like out sinus or to mention this question that has to be

such a nose or in the usa much to be a good time for you in your assign just done to a ph. d at harvard. and now kids lectures on diseases such as our assignments in dementia. the novel still alice was made into a film the one. and i'll sca synopsis when narrow transmitters are released. this is where the signals are transmitted or communication happens. this is where we think feel, see here, desire. and remember a synopsis. we're all timers happen. let's zoom in on this and apps and look at a cartoon representation of what's going on. this afternoon. i send you, a scientist explains how forgetfulness is different from a pathological inability to remember. so let me give a couple of examples to illustrate this.
