leading cultures around the world, people learn to classify small handful of animals of edible, and all the rest they classify as disgusting. w series about our complex relationship with animals. the great debate, what you know on youtube, dw documentary, the picture building your dream home. now picture that home coming out of a giant printer, sounds odd, but it makes sense. 3 d printed houses are faster, cheaper, and more climate friendly to build. what that looks like exactly as one of the stories we will be exploring. and here is what else will be asking on this week, sufficient. why isn't indian 1000000000?

they're demanding a 70 hour work week. is working from home. really better. m y, r and germans taking their foot off the gas pedal. welcome to made the w's business magazine month easy. now, here in germany, the construction sector is faltering, struggling under the weight of high interest rates of labor shortages and to little financing. and that's especially problematic right now, because we need new buildings more than ever to become climate neutral. but there's hope on the horizon in the german city of high to back. that's where your biggest a 3 d printing structure is being built layer by layer. instead of brick by brick, this machine does the work of several construction workers paid ladies down the concrete in layers and can build 4 square meters of wall per hour. that's how your ups and lodgers, 3 d printing building is being constructed and industrial building without windows

site manager. she can easy, we'll go from nigeria. we studied in germany is happy with the progress but when you talk about, so if you skip this like this where you have this type of fan or fat conceptual way, you have it with the next step to an order. and you obviously clear it's, it's best that, that perform well for this. then we, i might have more than 3 times fast i done called us and i did there's enough concrete in this time low to last for 2 days. keep travels from the who's into the nozzle that runs along the track. the process isn't just faster, it also needs less material and review of workers. and it's cleaner than unconventional construction sites on we need to build this. the for the dressing here is just sort of people one present that or press the princess one present that

or present missing lesson on one person that just works at a mix. everything is good with the cost on the list within it too, which is basically what i do. as construction site manager, who's responsible for checking the concrete mixer. he also takes care of office work on a smartphone. it's a much more relaxed atmosphere than on other sites. at intervals, they attach anchors to support the double walls. his colleagues monitors the 3 d printer on the computer screen. but how does the free printer know what to print? so basically the process is that the, i guess that's designed to build this was all i have, you know, we improve with that. yes, this is what is possible. it is what is not possible. then after the design it gives us this set file. that is the, the step 5, which is what i can send the outline design or the builder. and then when, when slices with a slides, that will was suddenly

a set price for the slides and then we slides it. then we get the g quote. then we send it to the printer and then we've got the price. here the a german company constructed the building with the b o, d 23 d printer made by the danish company, cobalt. the structure, cement ceilings are being poured conventionally and are supported until the concrete drives. it takes 6 months to build the building, 54 meters long, 11 meters wide, and 9 meters high. the building doesn't require any windows because we're only house computer servers. the architect, dion, 5 months, has designed the largest and highest 3 d printed building ever. it's made possible through the use of steel girders. a new development in 3 d printer construction this as a result of special attraction is an experiment with this construction method to

you and find out exactly what you can create within the guidelines of some very simple architecture requirements. that's not possible with any other technology. and that's what drove us, having succeeded the owner and developer is a real estate agent who wanted to build something new and innovative. on the landmark site, the price was high, so we needed to know that it would generate a profit to. yeah, i'm here is because i'm 3 invested a total of $2500000.00 euros here, including the land. and i can't tell you what it would have cost if we had built conventionally equipment because we switched to 3 d printing relatively quickly each time i just wanted to know, can i make it economically viable with 3 d printing figures this and i did id pull team one best option because the site manager also has to do some work by hand, especially the places where the printer stops and starts. he might have to make small corrections, but he doesn't ever want to go back to conventional construction. i really don't

think i would be moving back to the big convention article. so sideboards, i mean, nobody knows the future, but i didn't believe that the printer printed with go on grow higher. i'm done with this. uh, i think i would remain with the tray difference in building with 3 d printers is rapidly moving out of the experimental phase and into the commercial market. as for to get easy, oh good t i just 3 d printer have enough construction contracts for the next 2 years. which scripting you belong to? are you a master procrastinator or do you follow a strict schedule and get your work done long before it's due? deadlines can be extremely stressful and cost strong emotional responses, but they can also be important milestones and some say, the closer the deadline, the more efficient we are. so should we fits deadlines or double down on them.

too many projects deadlines to type extreme time pressure. nothing gets done. deadlines can be a curse or a blessing. deadlines are also indispensable. british historian, serial north code, parkinson formulated a law and 1955 work expands and proportion to the time available to complete it. in other words, the short of the deadline, the more efficient the work he gave the example of a pensioner who has no deadlines and wants to write a letter to her niece. it takes her an hour to find the right card at another hour to find her glasses. she struggles to find the right words for 2 hours. before she leaves the house to send the card,

she thinks for another 20 minutes about whether to take an umbrella with her. over all the old woman spends almost an entire working day for as others would need just one hour. for business is such a time, extension without a deadline would be a disaster. these days, especially work is becoming more and more concentrated. so could we simply shorten deadlines, further, according parkinson's law, and therefore increase productivity? that's not a good idea, because if deadlines are not achievable, employee recognition, trust and motivation will suffer. and quality will also suffer until everything crashes that wasn't parkinson's idea. deadlines should therefore be tight, but reasonable preferably broken down into small steps. then the work can be done efficiently, and deadlines are not harmful,

but helpful or another way to boost efficiency is to have more free time, like getting extra days off during the week. that's one of the benefits of a 4 day work week. that's an experiment that's currently underway in many countries in europe, including in germany, working smarter, not harder as the money shot behind the idea. and we've come a long way to that destination. only 200 years ago during the industrial revolution, workers 1214 hours a day, 6 days a week. and even today, the number of hours in days we work on average is heavily dependent on the country where from, according to the international labor organization, citizens of the island nation of on want to spend only 25 hours a week working citizens have gone beyond the other had spent twice as many hours a week at work, and the billionaire and india wants to go even further. the mariana

mercy is the co founder of the indian software company and sources. and he's a billionaire. she has suggested that young people in india should work 70 hours a week to further boost economic growth. but why? i didn't quite understand that. and so not, i'm with these families wrong. if it was or anything, it's the senior bosses perhaps who need to be the ones that you know, they should be working hard because they are the ones perhaps who have very likely to give you the actual generational value of all many people in india work under a very hard conditions. long working days are quite common. the average fine. uh, especially i ones the me skate on skilled workers. would range anywhere between 10 to 6 being offered they, even in the i t sector for many,

well trained programmers work high expectations lead to long working days. the contract is basically saying that you want to be available. so in that sense, it's actually why image of the notion of a specific what the game. so the walk then actually spills over into the leisure game. and there is no way you can escape uh, you know, say that, look, you know, i'm no longer at the workplace, so i not have no, no obligations really didn't know you any service. this is not something that is expected off an employee. one working hours can have serious health consequences among those who work more than 55 hours a week, 745000 people worldwide die of a stroke or a heart attack each year. the figure is highest and south east asia with over 318000, followed by the western pacific with 208000. the eastern mediterranean region was 77000. in europe was $57000.00 deaths per year. america as

a whole was around 43000 and africa was just under 40000 they spend less time doing things that we know are good for their health. so exercising, spending time with friends and family sleeping, taking time off when they're sick, right? a lot of people feel pressure to keep working when they're else in most european countries, people work less than 40 hours a week. but how did this figure actually come about? the 8 hours is fairly arbitrary. it comes out of a work or movement to have 8 hours of work, 8 hours of rest in 8 hours to do what you want. so that 8 hours, which we've come to think of as being the, you know, the standard is really not something that was ever established as the right number of hours for people to work. today. there are many working hours models around the

world. germany is currently considering reducing its work week to 4 days. other countries are sticking to longer working hours, depending on the culture, economic situation and employee rates. at 52.6 hours, the united arab emirates as the longest average work week in india, it's 5 hours less. in china, people work more than 46 hours per week. in the us. it's 36.4 hours. well, germany is one of the countries with the shortest work week. the 34.3 hours this has been hard one over the past century. and yet many germans still feel that the work life balance is not right. the. we need to be bob from the, the idea that if you would use working hours the, the work or when it went in the employer, we lose. that's not how those things work. after all,

employers also benefit it has long been proven that less work does not necessarily come with the expense of productivity. on the contrary, a good work life balance makes happy employees, and they often achieve more in less time. what does your ideal work week look like? how much we work as one factor to consider where we work as another around the world working from home has become increasingly common in some countries more so than and others? india, for example, is a front runner. indian workers spend 2.6 days a week working from home in the united kingdom. it's 2 days in germany, 1.4 and then shine out 1 point one and working from home is much less common in south korea at 0.5 days a week. but what are the pros and cons of working from home? what is the down science of working from home?

working from home is popular worldwide, no commuting easy child care, doing housework during your break. but is it a good work life balance and good for productivity? too much working from home can indeed have negative effect. the boundary between work and leisure is blurring, working before or after regular working hours reduces people's well being. this is exactly what soon happens when working from home writing a quick email after the children are put to bed. after all, you can pick them up from nursery during working hours. a work life balance track. if you managed to keep to your working hours, the flexibility can be more satisfying. and contrary to popular belief, people who work from home are more committed than office workers. still, the more often you work from home, the more stressful it is. although study participants reported better concentration

when working from home, they complained of headaches, listlessness nightmares, and sadness. most of the study results are still new and they sometimes differ from each other. but don't forget that will work place is also a place of vital interest and a social community. one thing is clear, if you strike a healthy balance between working from home and the office, you can definitely benefit from both options. a breaking out of old habits pays off, and that's not just true for our work habits. germany, speed limits, or rather the lack there of is deeply invest in the countries driving culture. more than half of germany's highways. there is no speed limit at all, meaning drivers can go as fast as they want. but driving more slowly could save millions of tons of c, o 2 emissions every year. never the less germans refused to take their foot off the gas pedal no matter the benefits. why is that?

the assistance of the german autobahn maybe if you're visiting because for many locals, hurling down the highway at top speed is just another day of driving. germany could save millions of tons of few to a year if it implemented a speed limit. so why doesn't the self proclaimed cream power tickets put off the gas? in germany, the debate around the speed limit is polarizing a slight majority of the population wants one. but the opposition is loud. let's click finish off. if it doesn't make sense to drive 200 kilometers per hour, just to have some fun or feel superior to other people. that's the thing we should keep it as it is. we are restricted everywhere in austin. both apparently gas prices stood on high enough to make people drive to the west bogo. why do we build cars with more than 50 horse power? we can only drive a 100 kilometers per hour and assign them. and spoiler alert,

this discussion often 1000 for evolve around fact gets a kind of now. so to say, in motion i did phase, this is katya dear. she wrote a book about mobility in germany, costs people one to stuck, to be free, to have f. we will of drive really, really fast, but let's take a look at the facts 1st. germany has more than 13000 kilometers of autobahn. famously well maintained and toll free for cars. most countries in the world got speed limits to improve road safety or to cause or fuel get in germany, you can drive as fast as you want and about 70 percent of highways. opponents of the speed limit argue that there are fewer road that's per kilometer on the autobahn than in some nation, such as france or italy. but experts like the german road safety council will say it will become even safer with a limit in recent years. but discussion has shifted to another aspect, the climate. the one thing also these agree on is that

a speed limit on these highways with lower emissions. the question is to what extent will according to the latest study, by jeremy's environment agencies, the country could save up to $6700000.00 tons of c o 2 per year. if it implemented a speed limit of a 120 kilometers per hour, that's about as much as low emission in countries like rolanda in eritrea polluting the year. another study commissioned by the car friendly ftp party puts the savings much lower at $1100000.00 tons per year. so realistically speaking, how substantial really is a cut of one to 6000000 tons of to, to, for a top looter like germany. the opponents of the month to a speed lead me to argue that the emission reductions would be 3 via julia much really research of the transport and climate policy. they just choose the denominator that would make it appear ridiculous, the ridiculously small. but i think if you, if you choose a date that, that the right, the nominator, the reduction would be substantial. the denominator he's referring to is the gap

between how much the german transportation sector should be emitting, according to the federal climate protection act. and how much it actually is a meeting in 2022, the sector went over to 2 emissions targeting 9000000 times a speed limit to reduce that different significantly if they go with a german environment. agencies estimates if it go with the liberal parties estimates the limit could reduce a portion of the success of missions. it's such a low line hanging fluid in terms of no age weight will have other benefits in terms of safety and reducing road death. and he's already exists in, in pretty much any other country in the woods. but for some germans, that's a big they see driving fast as an expression of their freedom and cars as a part of their culture. and some of john and see it as a kind of d n a. i think it's that it's sorry to say with, i don't know if it blocks the nazi dictator promised to motorized germany. in the 1930s, a venture that he said would create jobs and dr. taking

a lot decal development. he wanted to lay the groundwork for one of the earliest highway networks in the world. for a while, the nazis implemented no speed restrictions. that is until resources started running low during world war 2 and altima and drivers had to stick to a limit of 80 kilometers per hour to consider of gas. after the war, having autonomy became crucial to many german. germany was only destroyed whether it was no hope. the weather was paper. wow. yeah, coming back from the front and the car was a kind of freedom side. owning a car was d aspiration that turns more and more feasible. as the car industry started booming, producing cars became the answer to rebuilding the country's economy and driving them fast became the answer to rebuilding its freedom. for decades, many germans fought tooth and nail for this liberty. anytime anyone messed with the right to drive fast, they were met with outrage. perhaps because in the country with tens of millions of

cars and christine roads, driving fast, much of the one of the easiest ways to find the place of freedom. this list of freedom has become a bit of a sewing point abroad. torres even come to germany to drive as fast as possible. but if other people also find driving fast so fun wives, germany, one of the only countries that still allows that. after all this time, the speed limit can hardly be sold as a relic of nazi germany. well, the tuning car industry that provided many germans with a taste of freedom back then a still around of course. and it's very influential. the line between politicians and the car lobby has long been blurry. so you'll see this kind of what i'm driving because i did to effect the step out of politics. and they've got to go to the industry up to the lobby organizations. as for the speed limits, we can't say that the car lobby has actively petition against it in government. but we know the conservative and the liberal party currently stand in the way of this

restriction. and so it is most of the industry we need in general, widget speed limits on all the launch. it's as a spokesperson for the vda, an interest group for germany's automotive industry. the situations adapted speech recognition. the video suggests digital boards could show a speed limit when bad weather or traffic conditions require it. according to the group or richard limit would have minimal effects on the climate or road safety. it's faction reference as a study that says the limit could cost german society more than a $1000000000.00 euros. the study calculated how much time germans would lose if they drove slower, and how much of an average wage they would miss out on as a result. but this 2023 paper published in the journal for ecological economics disputes, assertions, like this. it's cost benefit analysis of germany could save hundreds of millions every year because yes, there is a cost of a speed limit. the benefits, like paying less for fuel damages from accidents,

and even the future effects of climate change outweigh these costs. reason that tends to implement a speed limit, have been denied in parliament because one of the parties and power the car. finally f t p. block the issue from being part of the coalition of bringing instead, some opponents select a point to alternatives to save emissions. like going electric. many car producers are becoming more open to the shift. after all that you has banned the sale of new petrol and diesel cars from 2035 in germany, it's very slowly incentivizing people to use electric vehicles. but there's still tens of millions of cars with combustion engines on german roads. and not everyone can afford to get rid of stairs or wants to beyond that, the country has the potential to improve public transport and rural areas and revamp a train system that currently is awesome, lead and unreliable. but the solutions take time for many environmental researchers stress is that a speed limit is one of the fastest mechanisms we have to lower emissions in the meantime. in my opinion, if the german government funds even bring the tubs to do that, then i,

i wonder what was it can do to, to reduce the size of the admissions. i think we need to have like that uh said, she was assembled. it's a bed of dreams as driving fast and owning a cough. for some people this would feel like an attack on their culture, their personal freedom. but it would put jeremy on par with most countries in the world. the breaking out of routines, habits, and all the ways of doing things opens up space for new ideas that applies to all areas of life. whether it's how we build our homes, how we work, or how fast we drive, we hope this episode could give you some food for rethinking things for turning in . and so your next time the
