Ancient Samurai Armor | by williamcho

Where does this saying come from? It's from a seventeenth-century samurai warrior. This way his key to successful living.

No fear. There should be nothing in this life that you are afraid of. If there is, you might need to overcome that fear. Here I have to confess to a certain fear of heights. Recently, owing to leaky rain gutters, I had to crawl out on our roof. I gritted my teeth and kept repeating, "No fear, no fear", until the job was done. Oh yes, and of course I didn't look down. Whatever your fear, face it head on and defeat it.

No surprise. Life seems to be full of them. You're going along swimmingly and suddenly something huge rears up ahead of you. But if you look carefully, there were clues all along the way that it was going to happen. So why does life seem to surprise us then? Because we are asleep half the time. Wake up and nothing can sneak up on you.

No hesitation. Weigh up the odds and then just get on with it. If you spend too long thinking, the opportunity will have passed. Once we have looked at the options, we make a choice; then, go for it. No hesitation means not waiting around for other people to help out or make up our minds for us. No hesitation means if there is a certain inevitability about a situation then just throw yourself in, head first, and enjoy the ride. If there is nothing to be done then waiting doesn't help.

How would we live in a world without oil? -PAU 2016 inglés Madrid resuelto

>Exámenes selectividad inglés resueltos C. Madrid

What would happen if our oil supply were shut off in a day? First, there is transportation. With the overwhelming majority of the oil we produce devoted to powering our vehicles, the impact on getting around would be most dramatic. Price-speculation would begin right away, and long lines would form at gas stations. Soon, we would all be looking for an electric car or converting our vehicles to run on natural gas. But it would not be long before natural gas supplies were also driven to extinction.

Fuel shortage is not the only problem our enslavement to black gold would cause. We also need to keep the lights on and blackouts would soon begin. It gets much worse still, of course, because a world without oil would quickly become a world without all of the products made from petroleum that we have come to know, love and depend upon. The list of essentials that we would soon be doing without is prodigious: medicines, paints, utensils and equipment, virtually all plastics, etc.

Eating would get tougher, too. If no one can truck fresh vegetables from across the country, we might be inclined to go back to basics and grow our own food. Local farmers would become a necessity, not just people who sell us honey at the street fair. It is an interesting thought experiment to picture such a world. Though the scenario is unreal, of course, taken to its logical conclusion, it encompasses so much more. A complete extinction of oil would lead to a rapid breakdown of society, desperation, lawlessness, wars and untold suffering.

Better ways to learn- PAU 2016 inglés Madrid resuelto

>Exámenes selectividad inglés resueltos C. Madrid

New studies challenge the notion that a high test score equals true learning. Although a good grade may be achieved in the short term by cramming for an exam, chances are that most of the information will be quickly lost. Indeed, these surveys show that over 70 % of students probably don’t need to study more – just more effectively.

Based on decades of brain science, experts offer students a new method for learning. “Students tend to sit there and push themselves for hours, when there are other ways to make the learning more efficient, fun and interesting, which will maximize their learning potential,” researchers say. For instance, rather than sitting at the same desk studying for hours, changing the scenery will create new associations in your brain and make it easier to recall information later. Another way to signal to your brain that information is important is to talk about it. Self-testing and writing down information on flashcards also reinforces learning.

Another technique is called “distributed learning” or “spacing”. Long study sessions may seem productive, but chances are that learners are spending most of their brainpower on maintaining their concentration for a long time. That does not leave a lot of brain energy for learning. “The brain wants variation. It wants to move, it wants to take periodic breaks.” Scientists also confirm that repeating the information over a longer interval – say a few days or a week later, rather than in rapid succession – sends a stronger signal to the brain to retain the information, and this enhances learning.

Use or abuse of technology - PAU inglés 2015 Madrid resuelto

>Exámenes selectividad inglés resueltos C. Madrid

People in Britain now spend more time watching TV, gaming, and using their mobile phones and computers than they do sleeping. Research by a British communications agency found that the average UK adult uses technology for eight hours and 41 minutes a day, 20 minutes longer than they spend sleeping. One of the biggest reasons for this is Wi-Fi. People can get online almost anywhere, so they spend more time online. Nowadays, it is very common that people make telephone calls or surf the web while watching television.

The study, which examined the use of technology by different age groups, also found that six-year-olds understand how to use gadgets such as tablets and mobile phones at the same level as 45-year-olds. Another finding was that people understand digital technology better when they are 14 or 15.

According to Dr. Arthur Cassidy, a social media psychologist, technology is changing the way people communicate with each other. He warned that we are becoming more and more anti-social and we are moving away from face-to-face conversations because of technology. He added that people are now saturated with digital technology and are becoming psychologically dependent on their smart phones.

Dr. Cassidy linked the increasing cases of Internet and social media addiction among youngsters with problems in mental and physical development. Perhaps we should think of recreational screen time as a form of consumption in the same way that we think of sugar, hours of sun, ... – measured in units of hours per day.

Go on two wheels - PAU inglés 2015 Madrid resuelto

>Exámenes selectividad inglés resueltos C. Madrid

“Beat the Tube strike, get a bike!” During the 48-hour shutdown of London Underground in February 2014, thousands did just that and took to two wheels. During the General Strike of 1926, the middle-class volunteers who drove trains were strike breakers. Similarly, these two-wheeled commuters were trying to beat the Tube strike.

With every turn of a bicycle wheel, human freedom is advanced. Cyclists do not have to face timetables; through their own sweat, they make their way in the world, free from following rigid lines of steel and electricity. The bike is individualism in action.

The bicycle is a reminder of the freedoms people enjoyed in the lost Victorian days. You pay no taxes or duties; you need no licence, permit or certificate of proficiency - you just get on your bike. And any cyclist with road sense will have a relaxed attitude towards highways regulations. It is absurd to give dog-like obedience to a red light when your eyes and ears tell you it is safe to go.

The bike has always pedalled individual freedom forward. The Lady Cyclists’ Association, founded in 1892, knew that it not only gave women an escape from home and husband, but also a reason to throw off constricting dresses. Many lady cyclists, for practical reasons, made cause with the Rational Dress Society who opposed “the introduction of any fashion in dress that either deforms the figure or impedes the movement of the body”.

The car is no longer a symbol of freedom, so if you want to feel free, go on two wheels.

Genetic fingerprinting - PAU Madrid inglés 2015 resuelto

>Exámenes selectividad inglés resueltos C. Madrid

On September 10th 1984, Alec Jeffreys, a scientist at Leicester University, was using DNA in an experiment to analyse the inheritance element in illness. DNA is the molecule that carries our genetic information. Looking at an X-ray showing the DNA profiles of his assistant and her parents, he suddenly realised that he had, completely by accident, discovered a revolutionary new method of biological identification. He called it “Genetic Fingerprinting”.

The importance of the discovery was recognised immediately by both the UK police and immigration authorities. The technique is now used in forensic science to assist police detective work and to resolve paternity and immigration disputes. It has also helped convict thousands of murderers, rapists and burglars while freeing many innocent people already in prison.

Genetic fingerprinting also has a promising future in the battle against disease. Scientists are storing genetic information of people in a “biobank”, in the world’s largest study of the role of nature and nurture in health and disease.

Many of the worst illnesses, including heart disease, diabetes and Alzheimer’s, are caused by complex interactions between genes, lifestyle and environment. However, it does have a negative side. Many people are worried that the discovery could badly affect our civil liberties. Jeffreys fears possible abuses of the system. He wants a global DNA database but without any information on race, health or physical appearance. As the technique becomes more sophisticated, all this information and more will be available.

Do aliens really exist? - PAU Madrid 2015 inglés resuelto

>Exámenes selectividad inglés resueltos C. Madrid

“Alien” is a word used to refer to beings from other worlds. Do aliens exist on Earth? No one knows the answer for sure, but it is a question that has been debated for ages. If history is to be believed, aliens have been a subject of mysticism in civilizations of places such as India, China, Babylon, South America and Arabia. The external appearance of aliens is also a much discussed matter: they have been depicted as green monsters, small creatures with arms and legs like humans, tiny viruses or beings that change appearance at will.

Many people nowadays, including well-known scientists such as Carl Sagan or Frank Drake, are tireless propagators of the theory that aliens are in fact regular visitors to Earth. This theory is supported by many reported alien sightings. For example, a person waiting at St Martin airport claimed to see fire in the sky; the fire suddenly transformed into a silver ball, moved over him like a jet and vanished in a few seconds. And two brothers in Chile said that they saw a humanoid creature about 80 cm tall, shiny and red, who resembled a child wearing a driver’s suit. 

However, others believe that aliens are just figments of imagination. This view also has scientists on its side, such as Enrico Fermi. He proposed the famous “Fermi paradox”, which states that there is an apparent contradiction between the strong belief in the existence of extraterrestrial civilizations and the present lack of solid evidence for, or contact with, such civilizations.

Putting the two views together, we cannot be sure if aliens are real unless and until we have strong evidence about their existence.

Cup of tea? - PAU Madrid 2015 inglés resuelto

>Exámenes selectividad inglés resueltos C. Madrid

Tea  is  a  huge  part  of  British  culture  and  heritage.  They  treasure  tea  breaks, teacakes,  tea  parties,  afternoon  teas  and  high  tea.  And  despite  the  increase  in coffee houses, tea remains their preferred beverage. So much so, they consume over 165 million cups of it every day.

Tea  was  a  relative  latecomer  to  British  shores.  Although  it  dates  back  to  the third millennium BC in China, it wasn’t until the mid-17th century  that  the beverage  made  its  appearance  in  England.  Samuel  Pepys  first  mentioned drinking  tea  in  his  journal  entry  for  September  1660.  Since  Pepys  was  a member  of  the  wealthy  and  fashionable  London  set,  his  failure  to  mention  tea earlier suggests that it was still unusual at that time.

Yet  it  became  known  in  Europe  very  quickly  after  its  introduction  there.  Two years  later  King  Charles  II  married  Catherine  of  Braganza.  Catherine  was  a Portuguese  princess,  and  a  tea  addict,  and  it  was  her  love  of  the drink  that established it as a fashionable beverage at court and among the wealthy classes.

Tea was particularly interesting to the Western world because it was very easy to  prepare  and  it  revived  the  spirits  and  cured  mild  colds.  In  fact,  in  the  18th century tea was thought to be a wonder cure for all manner of illnesses. It even played  a  big  part in the  Industrial  Revolution  because  the  stimulants  increased the number of hours labourers could work in factories.

Nowadays, whatever the occasion, the nation puts on the kettle for a cup of tea. It’s a drink that cheers and consoles, and it’s good for health and well-being.

Soap operas - PAU Madrid 2015

>Exámenes selectividad inglés resueltos C. Madrid

Watching  TV  is  a  very  popular  pastime  in  Britain,  but  what  kind  of programmes  do  British people  like  to  watch?  Well,  the  most-watched  TV programmes  are  dramas  based  in  one  neighbourhood  that  try  to  depict ordinary life. We call these dramas “soap operas” or “soaps”.

Most soap operas these days are shown in the evening. Each show will have several  different  storylines  happening  at  once  that  continue  over  several shows.  The  same  actors  will  appear  in  every  show  too.  There  are  lots  of different  soaps  on  in  the  UK  these  days,  but  there  are  three  main  popular

ones.

Coronation  Street has  been  on  since  1960.  It  is  set  in  a  suburb  of Manchester and it’s supposed to represent working class life in the north of England. Then there’s Eastenders, which started in 1985, set in the East End of London. And we should not forget Emmerdale, which is set on a farm in Yorkshire, in the north of England.

In  the  early  days  of  TV,  most  of  these  daytime  dramas  were  aimed  at entertaining  the housewives  who  would  traditionally  be  at  home,  probably doing the washing. Companies selling washing powder would advertise their products   at   times   when   these   dramas   were   on,   and sometimes   those companies would even sponsor the drama. Hence the word “soap”. So what about the word “opera”? Well, that’s because these dramas are often an exaggeration of real life. They are supposed to represent ordinary lives but, to  make  them  entertaining,  lots  of  dramatic  events,  like  murders, divorces, affairs,  etc.,  all happen  probably much  more  regularly than  they would in a normal neighbourhood.

Cell phone jammer - PAU Madrid 2014

>Exámenes selectividad inglés resueltos C. Madrid

It might look like a walkie talkie, but that little box is more powerful than you think. When a cell phone jammer is turned on, it can block any cell phone service in the area. Using one is not only a federal crime but is could result in a 16,000 dólares fine and jail time.

But that did not stop Eric, a man from Philadelphia, who was fed up with the chatty cell phone talkers on the 44 bus. According to a TV channel, Eric would fire up that jammer when he did not want to hear the conversations. "A lot of people are extremely loud, no sense of privacy or anything. When it becomes a bother, that's when I screw on the antenna and flip the switch", Eric told the reporters.

Eric claimed that he did not know it was illegal to block a cell phone sign, and thought it was a "grey area". He said he was under the impression that it was only illegal when blocking television or radio signals. "I guess I'm taking the law into my own hands and, quite frankly, I'm proud of it", he added.

This type of jammers is illegal because they could prevent cell phone communication in emergencies and because they can block other important signals such as police radio. But the bigger issue is that Eric is not alone in this jamming practice. Jammers are easy to buy at sites on the Internet. Police reported that other people in the New Jersey and New York area are using them as well. Maybe Eric's story will remind them all of just how illegal using that powerful device is.

Courses online - PAU Madrid 2014

>Exámenes selectividad inglés resueltos C. Madrid

For those students who struggle to leave their beds for a 9 a.m. lecture, the idea of studying online wherever and whenever you want – including under the duvet with a laptop – may seem like a dream come true. Soon some students will be able to do just that, as will anybody with a computer and internet connection, because a number of universities are planning to offer some of their courses online. Not only will these offer greater flexibility to online learners around the world, they will also be free.

EdX, an online platform founded by Harvard, Berkeley and the Massachusetts Institute of Technology, has already attracted 800,000 students from 192 countries since it started in autumn 2012. Significantly, the platform has developed an examination process, which means that online learners can graduate from an EdX course with a certificate and a grade.

However, it seems unlikely, for the time being, that online higher education will supersede traditional on-campus university degrees. It is well-known that many leading institutions, including Oxford and Cambridge, are absent from a list of 17 universities that have signed up to give away their course content online.

An obstacle preventing online courses from being taken seriously is the fact that many have a high drop-out rate. For instance, although 155,000 students registered online to take MIT’s courses on electronics on EdX, only 7,200 students completed them. With no tutors or lecturers to help you in person, self-motivation and discipline are required in abundance to see a course through to the end.

The decline of “Once upon a time…” - PAU 2014 inglés Madrid

>Exámenes selectividad inglés resueltos C. Madrid

Once upon a time, parents read bedtime stories to their children... But now it seems that the fairy tale is over. According to a poll of mums and dads with under-sevens, 36 per cent of parents never pick up a book with their little ones. Of those who do read with their kids, just 21 per cent make time for a story before bed every night. The study also showed that nearly half of the kids would rather watch TV or play with toys or computer games.

In light of the findings, Littlewoods.com, a British online retailer behind the study, has teamed up with 31-year-old British pop star Natasha Hamilton to get youngsters back into reading. Littlewoods and Natasha have just launched a bedtime story competition for children under seven to draw pictures and create their own tale. The winning entry will be turned into an audio book, narrated by Natasha. The pop star said: “As a mum of three, I know how enjoyable bedtime stories are for my kids. I’m really excited about seeing all the different story ideas. I can’t wait to see what the kids come up with. Choosing a winner will not be easy”.

Experts say that one of the key ways of helping children to learn to read and write well is to give them a love of books. However, some parents blame a lack of time for not reading with their children, while others say they are just too stressed, or that their kids are simply not interested. Surprisingly enough, the vast majority of parents were told bedtime stories regularly when they were little.

What’s in a Name? - PAU Madrid 2011

>Exámenes selectividad inglés resueltos C. Madrid

Recently, a couple in New Zealand was not allowed to name their baby son 4Real. Even though New Zealand has quite liberal rules about naming children, names beginning with a number are not allowed. They decided to call him Superman instead.

In many countries around the world, unusual names for children are becoming more popular, especially since the increasing fashion for celebrities to give their children silly names. In Britain, you can call a child almost anything you like - the only restrictions on parents relate to offensive words. Some parents choose names which come from popular culture. For example, there have been six boys named Gandalf after the character in the Lord of the Rings novels and films. Equally, names relating to sport are fairly common - since 1984, 36 children have been called Arsenal after the football team.

Other countries have much stricter rules about how parents should name their children. Countries including Japan, Denmark, Germany and Argentina have an approved list of names from which parents must choose. In China, there are some rules about what you may call a child - no foreign letters or symbols are allowed. As a result, just a year ago, a couple could not name their baby son @.

In Britain, some names which were previously considered old-fashioned have become more popular again, such as Maisie or Ella for a girl, or Alfie or Noah for a boy. But the most popular names are not the silly ones. The top names are fairly traditional - Jack, Charlie and Thomas for boys and Grace, Ruby and Jessica for girls.

January sales - PAU Madrid 2013

>Exámenes selectividad inglés resueltos C. Madrid

People who are addicted to shopping are nowadays called shopaholics. For these shopaholics, the post-Christmas period means only one thing - sales!
Across the country, prices are reduced on clothing, electronics, home furnishings and more, but London is the place for serious shopping, and you can certainly pick up some amazing bargains.
The sales start on Boxing Day, 26th December, and continue for the month of January, but the keenest bargain hunters get there early to be first through the doors. In Oxford Street queues form outside shops before pre-dawn openings for the start of their sales. At Brent Cross, in north London, hundreds of people queue at 3:30 am for the “Next” clothing store’s sale which begins at 4 am. Some hardy individuals even camp outside the shops to be first in the line.
Consumers who go to the shops are rewarded with discounts of up to 80%, as department stores join the sales frenzy. The shops are packed with people moving around as the sales get into full swing, with more than half a million people converging on London’s West End.
Some people are taking their partners shopping with them and buying their Christmas presents in the sale - a practical but unromantic way of making sure you get the gift you really want. For a less exciting but less stressful shopping experience, online retailers also participate in the January sales of
their own. The most organised of all are those who are already doing their present shopping for next Christmas, in the January sales!

Cleopatra was not killed by a snake - PAU 2011 inglés Madrid

>Exámenes selectividad inglés resueltos C. Madrid

The Queen of the Nile ended her life in 30 BC. According to legend, it was the bite of an Egyptian cobra which caused her death. After losing the Battle of Actium, her Roman lover, Mark Antony, is said to have committed suicide. Cleopatra did likewise, according to tradition, by killing herself. Her legacy survives in numerous works of art and the many dramatizations of her story in literature and other media. Cleopatra is usually portrayed as a great beauty and her successive conquests of the world's most powerful men are taken to be proof of her aesthetic and sexual appeal.
Now Christoph Schaefer, a German historian and professor at the University of Trier, has presented evidence on a television programme that drugs and not a snake were the cause of death. He said that the bite of a snake would have given her an agonizing death over several days. "Queen Cleopatra was famous for her beauty and was unlikely to have subjected herself to a long and disfiguring death," said Schaefer, the author of a best-selling book in Germany called Cleopatra.
"Cleopatra wanted to remain beautiful in her death to maintain her myth. The last female Pharaoh probably took a lethal cocktail, which, back then, was a well-known mixture that led to a painless death within just a few hours. We consulted eminent zoologists and toxicologists and they said that a snake bite would have been too uncertain and taken too long," Professor Schaefer added.

Make room for the robots - PAU 2012 inglés Madrid resuelto

>Exámenes selectividad inglés resueltos C. Madrid

When world-famous cellist Yo-Yo Ma announced that he would be playing with the Detroit Symphony, every seat was sold. However, Yo-Yo Ma’s performance was not the only thing that amazed the audience. The conductor did too. The conductor stepped onto the stage and lifted both arms to direct the musicians who played the song "The Impossible Dream." Until recently, that is exactly what this performance would have been. This is because ASIMO, the conductor, is only eight years old and 1.2 meters tall. It is also a robot. The scientists who built ASIMO equipped it with many abilities such as climbing stairs, recognizing faces, or even helping musicians make beautiful music.

Since the 1960s, robots have been doing jobs that are too boring or dangerous for humans. These industrial robots, unlike ASIMO, do not have a humanoid appearance. But now that robots are moving into our homes, many are starting to look more like us. One company has built a dish-washing robot called Monty. To reach the sink, Monty needed to be more than 1.5 meters tall and have a human-like hand to pick up coffee cups. "Once you make a robot for human environments," says the company’s manager, "you end up getting closer to a human shape. But building robots to look like people is not always necessary.” His company also makes a disc-shaped vacuuming robot called the Roomba and more than 3 million are already in use.

Nomophobia: Mobile Phone Addiction - PAU inglés 2013 Madrid

Are you addicted to your phone? According to a recent survey in the UK, almost two thirds of respondents were afflicted with “nomophobia” or “no mobilephone phobia”. “Some people get panic attacks when they are without their phones,” said Michael Carr, an adolescent psychologist. “Others become very concerned and make all endeavors to locate their mobile phone. I have clients who abstain from school or their part-time jobs to look for their phones when they cannot find them in the morning.”
According to the survey, the younger you are, the more prone you are to nomophobia. The youngest age group (18-24) tops the nomophobic list at 77%, which is 11% more than that of the next group – those aged 25-34. “This is the most tribal generation of young people,” said Carr. “Adolescents want to be with their friends on a 24-hour basis.”
The reasons that drive young people to nomophobia include boredom and insecurity, while some young nomophobes cannot bear solitude. “Many of my clients go to bed with their mobile phones just like one did with a teddy bear in the old days,” he said. “While teddy doesn't communicate, the phone does,” said Carr, adding insomnia to the list of potential problems. “Some kids cannot entertain themselves. The phone has become our digital security blanket.”
Accidents lurk while nomophobes fix their attention on phones. Nomophobes reported accidents while messaging or talking on the phone, which include minor road accidents, falling while going upstairs or downstairs and stumbling while walking. More than 20% also reported pain in the thumbs due to excessive texting.

Beauty over youth- PAU Madrid 2002

>Exámenes selectividad inglés resueltos C. Madrid

From the countless music videos portraying young healthy-looking beauties to a flourishing cosmetics industry that promises slow aging, women are led to believe that men primarily prefer youth to beauty. But a new study from Britain suggests that men go for older attractive women rather than younger plain-looking ones.
The new study by a psychologist of Chiterns University College shows that up to a certain age, men find attractiveness more important than youth when considering potential mates. The psychologist took a photo of a 36-year-old woman who was very attractive in the eyes of a group of men. They showed the picture to three other groups in their early 20s along with the same eight pictures of women aged 20-45 who had been considered less attractive. The researchers told the group the beautiful woman was either 36, 41 or 45 years old. When asked who they'd prefer as a long-term partner, all three groups of men chose her, regardless of how old they thought she was.

The study shows that beauty counts and that men are not concerned with the number of children they can have. The younger, plainer women will give them more children, but the fact that men are going for the "aging beauty" is indicative that beauty is more important at some level. But the psychologist also stressed that the study was based only on physical attractiveness and didn't take into account other characteristic traits like kindness, generosity, and caring, which were just as, if not more important, in determining long-term relationships.

Some people never forget a face - PAU inglés Madrid 2012 resuelto

>Exámenes selectividad inglés resueltos C. Madrid

A new study finds some people can remember faces of people they met years ago and only in passing. Others of us, of course, aren't blessed with that ability. In fact about 2 percent of the population has prosopagnosia, a condition characterized by great difficulty in recognizing faces.

The "super-recognizers", as they are called, excel at recalling faces. The study suggests that there is — as with many things — a broad spectrum of ability in this realm. The research involved standardized face recognition tests, and the superrecognizers scored far above average on these tests. Often super-recognizers are able to recognize another person despite significant changes in appearance, such as aging or a different hair color. They also recognize other people far more often than they are recognized. In these cases, they often compensate by pretending not to recognize someone they met in passing, so as to avoid appearing to attribute too much importance to a brief encounter.

Super-recognizers, then, really stand out in terms of their ability to remember people. They have extreme stories of recognizing people; it doesn't have to be a significant interaction. They can recognize someone who was shopping in the same store with them two months ago, for example, even if they didn't speak to the person. One woman in the new study said she had identified another woman on the street who served her as a waitress five years earlier in a different city. This outstanding ability could be important in courts, where one person's eyewitness testimony might thus be more credible than another based on their varying abilities to recognize a face.

Air-conditioned clothes in Japan - PAU 2014 inglés Madrid

>Exámenes selectividad inglés resueltos C. Madrid

A damaged Fukushima nuclear plant, severely limiting Japan’s power supply, has forced the country to reduce power usage. With restricted use of electricity, many people are looking for alternative ways to cool off in the hot Japanese summer. Hiroshi Ichigaya, engineer and president of the Japanese company "Kuchofuku", meaning air-conditioned clothing in Japanese, has invented a must for hot summers: the “Kuchofuku” jacket. The idea of “personal air-conditioning” struck Ichigaya in the 1990s, when he worked for Sony, trying to invent an air conditioner that would use little electricity. “It came to me that we don’t need to cool the entire room, just as long as people in it feel cool,” he said.
Kuchofuku jackets come equipped with a pair of battery-operated fans which draw air in, giving the jacket a puffed-up look. Ichigaya says the constant breeze inside the jacket helps evaporate all the sweat and creates a personal cooling system in the process. The goal is not to lower temperatures outside the body but expand the body's comfort zone, and eliminate the need for energy-consuming air conditioners.

Ichigaya's first collection only featured the standard air-conditioned jacket, but his collection has slowly expanded, along with the company. The Kuchofuku catalog now features air-conditioned cushions, shirts and pants, with fans installed in each pocket. Nearly 1,000 companies in Japan use Kuchofuku, including automobile giants, steelmakers, food companies and construction firms. The shirts and jackets are far from fashionable, but demand for them is soaring because they are not just economical. They also help boost worker productivity and aid in the fight against global warming.
