A group of Danish researchers recently made an interesting discovery about the relationship between our education level and how fast we age.
The researchers were led by Eigil Rostrup, who works as a doctor at Denmark’s Glostrup Hospital.
The study, published in the journal Human Brain Mapping, was based off of data from a group of 2,400 boys who had been born in the Greater Copenhagen area in 1953. The boys were tested both physically and mentally at the age of 20, and again when they were 57.
The testing gathered data on the participants general state of health, as well as their weights, smoking habits and IQs.
After the second round of testing at age 57, the researchers invited 200 men to the Glostrup Hospital for additional research: the 100 men with the best scores compared to their first test (at age 20), and the 100 men with the worst scores compared to their first test.
“We asked the participants to lie completely still in the MR-scanner without doing anything. Once in a while a light would flash in the scanner and at the same time the participant had to move his fingers,”
said Rostrup. This allowed the researchers to see how fast the men’s brains were able to switch from “default mode” (ie. when our brain is relaxed) to problem solving mode. Moving your fingers when a light comes on may not seem like a complex problem, but problem solving (even for the most basic problems) all happens in one region of the brain.
Rostrup and his team found that the men who had received a better education were able to more quickly and efficiently switch from default mode to problem solving mode than those with the least amount of education.
The findings suggest that an education or job that challenges you regularly can actually stave off diseases related to brain aging like dementia and Alzheimer’s. Here’s Rostrup again:
“In young people the brain quickly and efficiently switches from the default mode to problem-solving activity. But in elderly people, and especially those who are demented or suffer from Alzheimer’s, this change is slow and inefficient…
The better our brains manage this change from rest to problem-solving when we are 60, the better equipped we will be at the age of 80 when it comes to handling the tasks of daily life and avoiding the symptoms that are especially common in patients with dementia, including Alzheimer’s.”
Researchers and neuroscientists alike hope that this new study can help doctors predict conditions like dementia and Alzheimer’s ahead of time.
One thing is for sure though: mental exercise keeps the mind young just like physical exercise does for our bodies. Keep that mind sharp!
I’m no saint. Just like everyone else, I get frustrated with people from time to time. If you catch me after a particularly maddening encounter, you may hear the words “ignorant”, “bigoted”, “close-minded”, and maybe even “asshole”.
But one word you will never hear me use to describe a person is “dumb”. The increasingly popular idea that the world is full of stupid people is a basic misunderstanding of what it means to be “smart”.
Real intelligence is simply the measure of a person’s curiosity.
As a child, I was deprived of video games and cable television (in hindsight, I’m eternally grateful for it). So, I explored outside, dug things up, made messes, did questionable “experiments” in the kitchen, and burned stuff every chance I got (what little boy isn’t a pyromaniac?).
I also asked a lot of questions. I mean a lot. Why is the sky blue? Why is rain wet? Why does grandma keep an extra set of teeth in a glass in her bathroom?
One day I guess my mom just got tired of trying to answer them all, so she took me on my first trip to the library. I’ll never forget what she said as we entered that temple of learning:
“The answer to every question you could ever have is in here.”
I was immediately hooked. From then on, when I wanted to know how something worked or why something was the way it was, I went to the library and found a book I could read about it.
I wasn’t critiquing the authors’ literary styles, or analyzing their sentence structure, or looking for deeper meanings. I was just enjoying the reading and relishing in my newly found power to find answers to every question.
That’s why today I have a wealth of relatively random facts that I can recall whenever necessary. It’s not because I was any smarter than any other kid my age, it’s just that I had parents who showed me a place where I could ask as many questions as I wanted and actually find the answers on my own.
Calling someone stupid also means you don’t understand how the brain works.
The average brain is made up of about 100 billion brain cells called neurons. Each of these neurons has the potential to connect to any of the others.
If you can remember your combinations and permutations unit in 7th grade math, you’ll know that the total number of possible connections that can be formed between 100 billion neurons is equal to 100 billion factorial:
100,000,000 factorial = 100,000,000,000 x 99,999,999,999 x 99,999,998 etc. all the way down to 1.
So what’s the total number of possible connections? Well, I tried to do 100 billion factorial on five different online scientific calculators and they all gave me the same answer: infinity (the real answer is obviously not actually infinity, but it’s a number with about 25 billion zeroes).
That’s right. There are virtually infinite ways in which our brain’s neurons can potentially connect to one another, and it’s the combination of these neural pathways that allows our brains to function.
When we are born, there are very few connections in our brain. This basically means that our potential is limitless.
As we begin to get older, our brain realizes that certain abilities, like being able distinguish monkey faces as well as we distinguish human faces, aren’t really very useful. Consequently, those pathways erode away-the typical adult only maintains a few trillion pathways throughout their life.
I know the monkey example seemed a bit random, but it’s actually from a real study. In 2005, researchers demonstrated that six-month old infants could distinguish between the faces of different monkeys just as easily as they could between different human faces.
However, by the age of nine months old the toddlers’ brains had realized that the skill wasn’t useful, and most of them lost the ability. Only the babies who continued having to differentiate between the monkeys (ie. for whom the skill was still useful) retained the ability.
There is the potential for some extremely powerful, some would even say magical abilities within our brains. However, the brain’s number one priority is survival, so it limits things like creativity and imaginativeness to ensure that we can function well in society and provide for ourselves.
But sometimes, the part of the brain which holds back that dam of possibilities gets damaged, allowing glimmers of our superhuman potential to shine through.
That is the case with people suffering from savant syndrome. Savant syndrome occurs when a mental disability like autism damages the part of the brain that controls our basic functions.
Although those suffering from the condition usually lack the basic motor skills to tie their own shoes or dress themselves, the condition also liberates other parts of their brain, giving them some mind-blowing abilities:
A man who can read a book two pages at a time (one page with each eye) and remembers every detail about the 12,000+ books he’s read so far:
A man who flawlessly played Tchaikovsky’s Piano Concerto No. 1 after hearing it once. He was 16, never had any classical training, and had just learned to walk on his own a year earlier:
A man they call the human camera, who can recreate entire cityscapes, down to the number of windows in every building, after viewing it once:
When we are born, we all have the potential to be as smart as Stephen Hawking, or as funny as Richard Pryor, or as musical as Jimi Hendrix. But from that point on, who we become depends on the neural connections that are created by the environment we live in.
And not only does everyone have amazing potential, but everyone has something to teach you. Knowledge can be obtained from books or computers, but wisdom can only be obtained through experience.
Every person in this world has a life experience unlike anyone else’s. We all gain perspective about the world from the lessons we learn throughout our lives, so there’s a nearly infinite amount of wisdom we can obtain from those around us, if we’re willing to look for it.
Our brains are naturally curious, but this curiosity must be protected and fed for it to achieve its potential. Remember, Einstein was dyslexic and mildly autistic as a child, and he ended up becoming arguably the greatest scientific mind of our times.
Calling someone dumb makes them scared to ask questions- it stunts their curiosity, thereby inhibiting their ability to find out the truth on their own.
So, every time you call someone dumb, you are actually the one making society less intelligent.
When we talk about educational inequality in our country and the poor conditions of public schools in low income areas, we tend to focus on middle schools and high schools, and their inability to reach “troubled” youth.
This is definitely an important aspect of the problem, but the issues start much, much earlier.
One of the most important and most ignored aspects of educational inequality is the disparity in resources available for early childhood education.
In middle class or upper class families, a child is often given all kinds of educational toys and games to help the mind grow, develop, and prepare for formal schooling. Parents are also typically active in teaching the child basic lessons and skills through play.
But for low income children, this experience is very different. For one, many of them live with single parents who are working 80+ hours a week just to keep the lights on and put food on the table.
These parents don’t have money for all of the educational toys, games and camps that more well-off parents provide to their kids. Also, their demanding work schedules tend to leave them with very little time to spend with their child (and it is often only for a short period of time after an exhausting day of labor).
Although it can’t totally make up for the economic differences, pre-school was designed to help bridge that gap a bit. Unfortunately, less than half of pre-school aged children are actually even attending pre-school.
Check out the infographic below to see how this lack of quality early childhood education affects a child’s future:
This Fourth of July weekend saw joy, laughter, fellowship and fun. It also saw another rash of murders in the streets of Chicago.
The 3-day weekend starting on the 4th saw eight murders in Chicago. Two more have already been reported for today.
While this weekend was slightly more violent than others, it is definitely not an aberration. Easter weekend this year saw 45 separate shootings in Chicago. The weekend before that, there were 35 shootings in 36 hours.
In recent years, Chicago’s violence has the nickname “Chiraq”. Since the start of this year, the city has has seen 196 murders. That’s more than four times as many American fatalities as the 46 so far in Afghanistan and Iraq this year.
The homicides this weekend were a result of multiple shootings at Independence Day celebrations around the city which left another 60 people injured.
Murder totals in Chicago actually peaked at 943 in 1992, and steadily declined in the decade that followed. But that number spiked again in 2012, which saw 521 murders. The majority of these murders were related to gang activity and the increasingly lucrative drug trade in Chicago.
To combat the rise in violence, Chicago dispatched hundreds of extra police into particularly dangerous neighborhoods, and reached out to community leaders for support.
“We will keep building on our strategy, putting more officers on the street in summer months, proactively intervening in gang conflicts, partnering with community leaders,”
said Police Superintendent Garry McCarthy said in a recent statement.
It seems to be working. Last year, Chicago tallied 415 murders, the lowest that number has been since 1965. And as of June 30, Chicago had experienced nine fewer homicides than in that same period last year.
But these rates are still much higher than most cities. By comparison, New York City (which has three times more residents than Chicago) only had 350 murders in 2013.
So why is the murder rate so high? Many people would point to high rates of poverty, but Chicago actually has lower poverty rates than other major cities like New York, Los Angeles and Miami.
Poor schools also play a major part in the crime, but Chicago actually has a higher percentage of high school graduates over the age of 25 than New York City, Los Angeles or Houston.
There is no one reason for the violence in Chicago, but there are a few other major factors that have contributed to it. One of these factors is depopulation and gang fragmentation.
In the 80s and early 90s, the majority of the homicides in Chicago centered around low-income government-subsidized housing projects like Cabrini-Green and the Robert Taylor Homes.
Starting in the late 90s, the city carried out an aggressive campaign to demolish these high-rises as part of a plan to reduce crime. However, this just displaced tens of thousands of residents, exacerbating the issues of poverty they faced while simply spreading the criminals who had been sharing the buildings with them out to new neighborhoods.
The demolition of these centralized crime hubs has also led to a fragmentation of the gangs in Chicago. During the early 90s, much of the drug trade was controlled by Larry Hoover, who was head of the Gangster’s Disciples street gang.
This gang (which controlled a number of Chicago’s subsidized high-rises) was no stranger to violence, but it also had a very strict hierarchy that maintained unity and order amongst its gang members.
The arrest of drug lords like Hoover and the destruction of their headquarters created a power vacuum that broke Chicago’s gangs into countless smaller “sets”, which now battle amongst themselves for turf, power and money.
But maybe the biggest reason for Chicago’s high crime rates is the lack of jobs. Despite the fact that Chicago has higher levels of education than other large cities like New York, Houston and Los Angeles, it still has a much higher rate of unemployment (13.7%) than these other cities.
The gang violence exacerbates this problem by driving potential employers out of the inner cities, leaving only a handful of low-paying jobs to the residents who remain. This de-population also reduces property values which in turn further limits the public funds (ie. taxes) available to help fight crime and improve conditions.
Whatever the reasons are, the reality is inarguable: Chicago has a serious violence problem, and the fact that it doesn’t get the media airtime that Iraq, Al Qaeda ad ISIS do won’t change the fact that for every soldier we have lost overseas this year, we’ve lost another four youth in Chicago.
With the rise of modern technology, the look of the classroom has been changing rapidly. Computers are replacing workbooks, iPads are replacing notebook paper, and teachers are increasingly using social media to communicate with their students.

Back in 2010, Dawson predicted that newspapers would totally disappear from Australia by 2022. After getting significant press from the prediction, he expanded on his theory by predicting this date for a number of developed and developing countries around the world.
Click the map to enlarge it.
Though the years may not be exact, Dawson’s predictions definitely reflect the trends here in America.
For the second half of the 20th century, newspapers thrived, and ad revenue grew steadily from 1950 until around the year 2000, when the internet really began to take hold. In just the last ten years or so since then, newspaper ad revenue has plummeted back to its pre-1950s levels:
Dawson sees the demise of newspapers as the result of a number of factors, including an increase in the portion of our world that is educated and modernized, an increase in government control and censorship of media at the local level, and the advancement of digital media technology.
Check out this graphic he made highlighting the trends he believes will lead to the end of the printed paper:
The 2014 FIFA World Cup is just around the corner. All across the world, rabid soccer fans are eagerly awaiting the beginning of arguably the world’s biggest sporting spectacle.
However, many people in Brazil are not at all happy about the tournament. Between the stadiums and infrastructure, preparations for the Cup have cost Brazil an estimated $14.5 billion, and many Brazilians feel that this money should be being spent on improving schools and hospitals in Brazil’s infamously decrepit and crime-ridden favelas (Brazilian slums).
Brazilian street artists have been showing their disapproval with some powerful graffiti. Check out some of the street art below.
“The world cup takes our schools and hospitals and leaves us its ‘balls’.”
This incident seems to have really brought the brutality of the group to the forefront, despite the fact that less than a month earlier, Boko Haram shot and burned 59 male students at another Nigerian boarding school, telling the girls to leave and go find husbands (Boko Haram is extremely conservative, believing women should not be educated and should play a traditional domestic role in the family).
Earlier today, the Obama administration announced that it would be increasing its role in the search effort, sending a team of military, intelligence and law enforcement personnel to assist the Nigerian government.
I’m all for doing anything that might increase the chance of returning the kidnapped girls to their families, but please excuse me for being cynical about this latest news. For me, it immediately recalls memories of the botched #Kony2012 campaign.
If you need a refresher, back in 2012, the non-profit group Invisible Children launched a campaign with the goal of raising awareness about Josef Kony, leader of the LRA (Lord’s Resistance Army), and his practice of kidnapping young boys and turning them into child soldiers.
Following the explosion of the #Kony2012 campaign, both local forces (like the Ugandan army) and specialized foreign units (like the U.S. Special Forces) stepped up their activity in the region, with hopes of capturing Kony and ending his reign of terror once and for all. Two years later, he is still at large (most likely in a remote area of the Central African Republic), with many of his LRA soldiers still with him.
My point is this- when we hear about horrific crimes like Boko Haram’s recent mass-kidnapping, we respond with our most unrefined emotion: anger.
We get pissed off that such backwards and extreme ideologies like those espoused by Boko Haram even still exist in our modern world. We get pissed off that the local governments are either too corrupt, too scared or simply too apathetic to really do anything about the crimes. We get pissed off that some people aren’t as pissed off about the tragedy as we are.
When we get mad, we get vindictive. We hear about the horrific things being done to the girls in begin to equate justice with vengeance, while completely losing track of the real issues here.
Everybody seems to want to send in all our best guns (figure of speech) and shoot Boko Haram out of the jungles where they’re hiding- this is simply unrealistic. The central region of Africa has millions of square miles of virtually uncharted “bushlands” (African use the term “the bush” to describe uninhabited dense areas of forest).
Trying to track down Boko Haram and the kidnapped girls would be like trying to find a needle in a haystack… if that needle was constantly moving locations and was way more familiar with the layout of the haystack than you.
The American government is famous for saying it won’t negotiate with terrorists (even though we’ve done so on many occasions). If Obama were to announce right now that we were negotiating a ransom for the girls, he would likely be blasted in the media as a spineless terrorist-appeaser.
But would that really be so bad? Try to remove your emotions from the decision- nobody likes the thought of rewarding people for committing heinous crimes like this kidnapping, but we’re already three weeks removed from the original crime: what are our chances of recovering even a fraction of the girls (alive) using force? I’d say that chance is almost zero.
Boko Haram promulgates a message that western culture (specifically western education) is evil, and that western powers like the United States are trying to spread evil progressive ideologies and create modern-day forms of colonialism. We cannot give them more ammunition for their propaganda machine.
One thing our foreign policy “experts” haven’t seemed to grasp in recent years is how we constantly create more enemies for ourselves by taking the bait of fringe militant groups. Look at Al-Qaeda for example: how many future insurgents did we create from all of the “collateral damage” (ie. civilian deaths) that resulted from our stubborn obsession with eradicating this group?
One of the biggest reasons why we are disliked by many people in other countries is that we are perceived as a schoolyard bully who is constantly trying to police the whole world. Sending in our special forces to fight a guerilla war in the jungle with an army that has no uniform and is full of young kids is just asking for trouble.
Boko Haram’s leadership would use this move as proof that the U.S. cared less about the girls’ well-being than about their own strategic interests in the region. And they would definitely make sure to publicize all of the graphic images, especially the ones of dead children (even if the kids were child soldiers).
Because of these factors, I think that negotiation is clearly the better option. It has the highest likelihood of recovering the girls safely and the lowest likelihood of becoming another black eye on our foreign policy record. Plus, it would show we cared more about the principles of equality and universal education than we do about maintaining a military presence around the world.
And if it was successful, why couldn’t we just go after Boko Haram afterwards? They would no longer have any leverage in the situation and the fact that we made sure to secure the girls first would probably make it a lot less likely that people would be suspicious of ulterior motives.
Obviously, we can’t ignore the fact that we would be, in effect, helping to fund Boko Haram by paying them a ransom for the girls. But we have to ask ourselves what’s more important to us: the lives of the girls, or revenge against Boko Haram. The latter will always be an available option, but we may be quickly running out of time to accomplish the former.
About three weeks ago (on the evening of April 14), the anti-western militant group Boko Haram (whose name literally means Western Education is sinful) stormed an all-girls boarding school in the Chibok region of Nigeria and kidnapped 234 female students.
“God instructed me to sell them, they are his properties and I will carry out his instruction.”
There was also a report last week that some of the girls were being sold as brides to their kidnappers for just $12 a piece.
Although Nigerian President Goodluck Jonathon has made speeches assuring that the government will find the girls, it doesn’t seem that much is actually being done, and Nigerians have very little confidence in the government finding the girls.
Last week, Naomi Mutah, a representative of the Chibok community from which the girls were taken, organized a protest outside of the NIgerian capital of Abuja. The protestors criticized the government for not doing enough to find the girls and fight Boko Haram.
Earlier today, the BBC reported that Nigeria’s First Lady Patience Jonathon called a meeting for those affected by the tragedy- the Chibok community sent Ms. Mutah to represent them. Following the meeting, Ms. Mutah was taken to a police station and detained.
The first lady is a very powerful political figure in Nigeria and apparently felt slighted that the mothers of the abducted girls had sent Ms. Mutah to the meeting.
Pogo Bitrus, another community leader from Chibok, told the BBC that he had been to the police station where Mutah was reportedly being held, but found no written records of her being there. He said he hoped the first lady would soon, “realize her mistake.”
The AP talked to another community leader, Saratu Angus Ndirpaya, who was at the meetings. She said that the first lady had accused the activists of supporting Boko Haram, and had even accused them of completely fabricating the abductions to give the government a bad name.
