How Many Calories Does Hiking Really Burn?

What’s possible in a week? If you dedicated seven days to the achievement of one goal, how ambitious could you make this goal? These were the questions that the multilingual friends Katy and Sara posed themselves when they determined to learn English in one week, to prove that it can be done and anyone can do it with the right methods.

They would attempt to liberate themselves from the distractions and responsibilities of modern-day life in order to cram eight hours of study time and I was observing some of the world’s most capable language learners at work.

The language learning expert: Sara

The friends set themselves the challenge of learning a language in a week in order to stretch themselves, and then it was a question of choosing which language to learn. English presented itself as a natural option; there are nigh on 300,000 English speakers in Germany’s capital, and the areas are dotted with stores adorned with signs in English.

“Truly understanding one’s environment requires one to first understand English”

The first operational step in the friends learning process was to decorate the entire apartment with sticky notes. This had an almost ceremonial touch to it as the friends delved into dictionaries and proceeded to label everything with its corresponding English name.

Within the space of about an hour it was impossible to carry out any menial task, be it making a coffee or flicking off a light switch, without first being presented with at least three different words related to this action.

Sara learning in the park

The importance of the other twin’s presence became immediately apparent as Katy and Sara delegated responsibilities for rooms to decorate with sticky notes. This simple task was augmented by continuous little tests that they would spring on one another, and the fact that they split up their day slightly differently and studied different topics meant that each twin became a source of knowledge for the other.

The most extraordinary moment came towards the end of the week!

The friends simply switched their everyday conversations to English, asking one another if they wanted tea or coffee, were ready to cook dinner or when they were going to leave the house.

Katy and Sara had numerous micro-challenges throughout the week. On the first day they were visited by a English friend who greeted them in English and complimented them on how quickly they’d picked up their first words and phrases.

They then learned the names of fruits and the numbers from one to a billion so that they could visit the English market (although they refrained from purchasing nine hundred thousand kumquats). Displaying their haul after their first functional exchange in English, they beamed with pride and a palpable sense of accomplishment before marching back home to study further.

Katy playing audio lessons

On our second visit to the brother’s apartment 24 hours into the week, we found them sampling dozens of different kinds of English snacks.

Like kids staring at the backs of cereal packs before heading to school, the nutritional information and various special offers and competitions on the packaging were analysed during snack breaks.

There was no moment of complete removal from the language learning process during the eight hours that the friends had allotted to it.

They were constantly using their existing knowledge to support the ever-growing knowledge of English, this being the root of their success.

“you will likely come across words that share common origins with your native tongue”

The friends spent a lot of time engrossed in books or on their computers and apps, flicking and swiping their way through exercises eagerly, but at other times they were to be found searching busily for English radio stations and write-ups of English football games on the web.

There is no definitive method to learn a language fluently

All too often, people enter their weekly language class to converse with their teacher, but then barely have any contact with other speakers and that’s not enough.

The old saying that we can solve problems more effectively when we sleep on it may be especially true if the problem we’re trying to solve is learning a new language.

Motivated Katy out to the library

Researchers from two Swiss universities wanted to know if they could enhance the learning of words from a foreign language by exposing people to the words during non-rapid eye movement sleep the deep, dreamless sleep period that most of us experience during the first few hours of the night.

To find out, they gathered two groups of study participants, all of whom were native German speakers, and gave them a series of Dutch-to-German word pairs to learn at 10 pm. One group was then instructed to get some sleep, while the other group was kept awake.For the next few hours both groups listened to an audio playback of the word pairs they’d already been exposed to and some they hadn’t yet heard.

The researchers then re-gathered both groups at 2 am and gave them a test of the Dutch words to uncover any differences in learning. And indeed there was a difference:

“The group that listened to the words during sleep did better at recalling the words they’d heard”

The simple yet potent trick the researchers employed is known as verbal cueing, and this isn’t the first claim made for its success while sleeping. But what makes this study different is that it puts a finer point on the conditions necessary for this trick to actually work namely, it only works when we’ve already been exposed to the verbal cues before we sleep.

Internet is always helpful

The researchers added a techie dimension by conducting electroencephalographic (EEG)recordings of the sleeping participants brains to track neural electrical activity during the learning period.

They found that learning the foreign words overlapped with the appearance of theta brain waves, an intriguing result since theta is the brain wave state often associated with heightened learning while awake (usually we’re in either the high-frequency, high-alertness alpha or beta states while awake, but it’s thought possible to induce theta state slower in frequency than alpha and beta through concentration techniques).

8 factors that make the teeth yellow

Do you envy the girl of the advertising of toothpaste? Are you embarrassed to laugh in public? In all the photos you leave with your mouth closed? If yellow teeth are a problem for you, we recommend that you read this article to know the main causes.

Why do I have yellow teeth?

First of all, you must understand that the point of comparison is never ads for dental creams, because they exaggerate the whiteness that teeth should have . Nor should we look at celebrities because they use expensive teeth whitening treatments to look that way.

The stains and yellowing of the teeth can develop both externally and internally. The former are more visible, but it does not mean that they are more frequent than the latter.

The reasons why the teeth turn yellow are:

Poor dental hygiene

Do not brush your teeth at least twice a day or do not floss daily accumulate plaque in the line between the gums and the teeth. In a short time the plaque hardens and becomes tartar.

That yellow substance that is only extracted in the dentist traps particles of food that increase the spots.

“If you want to remove the plaque and yellow particles from your teeth, go to the Dr. Roze dental clinic in Dubai. Here patient sit back comfortably and they make your smile brighten and beautiful. They use advance methods for the protection of gums and lips.”

Cigarette

People who smoke have darker teeth than those who do not have this vice. The culprits are nicotine and tar, two of the essential components of cigarettes. Quitting smoking will not only help to make the mouth more beautiful, but it will also bring several more benefits to your health.

Genetics

It is not a matter now to blame the parents or grandparents for having yellow teeth, since surely they also suffer it. Those people who have less enamel on their teeth due to genetic issues are more likely to stain at an early age.

There are also other defects of the genes that affect the development of enamel. This is the case of dentinogenesis imperfecta, where the layer is very superficial and easily damaged. Redheaded people tend to have yellow teeth because they have less ectoderm (the layer that builds enamel).

Age

The passage of time and aging cause the teeth to stain . That is why the color white is associated with youth. As we age, the layer that protects the pieces becomes narrower and wears out.

The edges of the teeth in adults are more translucent, more gray or more yellow.

Dental restorations

If you have made impasto in the teeth, you will have noticed that they turn yellow over the years. This is because the resin that was used for that procedure is more vulnerable to stains. It is advisable to change them at 5 or 10 years.

The amalgams of silver can in turn cause gray areas on the teeth, and especially on the teeth when repairing cavities.

Medicines

If they are consumed before 8 years of age, antibiotics, such as tetracycline and doxycycline, discolor teeth, as they are still developing. In the case of adults, medications that can stain teeth are:

  • Antidepressants
  • Antihistamines
  • Blood pressure regulators

Exposure to fluoride

This happens when the water that is drunk contains it in large quantities. It can also be due to the components of toothpastes and mouth rinses. The stains produced by fluoride are usually difficult to remove without professional teeth whitening.

Diseases

Certain infections cause problems in the enamel and the coloring of the teeth. On the other hand, some treatments such as radiotherapy and chemotherapy increase the risk of yellow teeth, since they produce a greater amount of saliva and plaque.

Drinks that cause yellow teeth

Eating habits are one of the fundamental factors for having white or stained teeth. The tooth enamel is wearing away and the dentine (darker color) begins to see.

Drinks that can cause yellowish teeth are:

Coffee

It is drunk all the time in offices and homes, regardless of the time of year, and is one of the biggest reasons why adults have spots on their teeth. The outer layer is very porous and can easily absorb the tone of dark drinks. Try to consume it with milk or cream.

Black tea

While many believe that it is healthier than coffee, in matters related to dentition is not the case. Tea has substances called tannins that can stain teeth.

Avoid drinking it alone and prefer to cut it with milk . Do not hesitate to choose green tea and white tea.

Red wine

Another dark drink that stains teeth. It is true that wine is good for the heart and the brain, as many researches indicate, but it is not entirely beneficial with oral beauty .

Look in the mirror after a glass of red wine and you will notice its effects. You can try a white or pink to reduce the spots.

Refreshments

For assumptions that could not be missing from this list. Cola drinks are not good for general health and neither for the aesthetics of your teeth.

In addition to their dark tone, they cause contractions in the gums and teeth when they are too cold. This causes greater porosity and propensity to stains.

In turn, the soft drinks contain citric and phosphoric acids that erode the enamel . Not counting the sweeteners and sugars included in the recipe, which cause tooth decay, among other oral problems.
