Study: One of the Keys to a Happy Life is Being a Generous Person

Let’s be honest for a moment. You’d probably be thrilled to have a cool million or 2 in the bank. Money can’t buy happiness, as the saying goes, but what you do with your money (as well as time and talents, for that matter) might have an awful lot to do with your quality of life. Sure, doing something nice for someone else feels nice, but a recent study suggests that generosity has a positive biological effect on the brain.


For the study, published in Nature Communications, researchers at the University of Zurich in Switzerland told 50 people they would receive $100 over a few weeks. The team asked 25 of the individuals to use the money only on themselves, and asked the other 25 participants to spend it on someone they knew.


The researchers wanted to know: Would the mere promise to spend the money on someone else be enough to make people happier?




Before handing out the first batch of cash, the researchers brought those in the give-away group into the lab and asked them to think about a friend they’d like to give a gift to and how much they would hypothetically spend. Then, the participants underwent functional MRI scans so researchers could measure activity in 3 regions of the brain associated with social behavior, generosity, happiness, and decision-making.


Those who had pledged to spend the money on other people were more likely to make generous decisions throughout the duration of the experiment, the team found, compared to those who had pledged to spend the money on themselves.


The group’s MRI’s showed more interaction between the parts of the brain associated with altruism and happiness, and the participants expressed higher levels of happiness after the study ended.


Furthermore, it didn’t matter how generous people were. Even giving away a small amount of cash impacted the participants’ happiness in the same way.


Lead author Philippe Tobler, associate professor of neuroeconomics and social neuroscience, said:


“At least in our study, the amount spent did not matter. It is worth keeping in mind that even little things have a beneficial effect – like bringing coffee to one’s office mates in the morning.”


He added:


“You don’t need to become a self-sacrificing martyr to feel happier. Just being a little more generous will suffice.” [2]


Co-author Soyoung Park says many questions remain unanswered. [3]


“There are still some open questions, such as: Can communication between these brain regions be trained and strengthened? If so, how? And, does the effect last when it is used deliberately, that is, if a person only behaves generously in order to feel happier?”


Earlier studies have shown that older people who are generous tend to be in better physical shape. Some research has even suggested that spending money on other people is as effective as medication or exercise for lowering blood pressure. [1]


So the next time you feel like treating yourself, consider treating someone else instead. It might make you feel even better.


Tobler said:


“It is worth giving it a shot, even if you think it would not work. In order to reap health benefits, repeated practice is probably needed so that giving becomes second nature.”

The Real Danger Behind MRIs

The Real Danger Behind MRIs | mri-fb | General Health Medical & Health Special Interests


Magnetic resonance imaging is a common preventative and diagnostic method used in medicine, and at times this technology can be invaluable. Of course there are some health questions associated with the practice, such as does the practice involve powerful magnetic fields? But for those who require them in case of an emergency, they can be extremely helpful. Besides the minute threat of magnetic frequencies, new concerns over the drugs used to produce clearer images have been shown to leave toxic residue in the brain. These findings have shown the importance of more stringent health monitoring prior to MRI application.


The Real Danger Behind MRIs


MRIs are typically safer than a CT scan, as they emit little to no radiation during the procedure. The real concern surrounding MRIs, in fact, has nothing to do with the technology at all. Patients are often given injectable drugs that improve the visibility of certain areas in the brain, which can be very useful for discovering health issues that could possibly be missed. [1] The issue is that these drugs may accumulate gadolinium–a toxic metal–in brain tissue.


The medications, known as contrasting agents, sharpens the resulting images; however, it may also be contributing to deleterious effects, many of which have yet to surface in any research. Toxic metals that build up in brain tissue are commonly associated with age-related brain declines, such as those attributed to dementia and Alzheimer’s disease. [2] Some research even shows that these drugs could be linked to kidney problems, prompting FDA to issue a “black box” warning on the drugs.



What You Should Know about MRIs


There are currently nine gadolinium-based agents in the United States, and two of the most concerning are made by GE Healthcare and Bayer HealthCare. Omniscan is perhaps the most commonly-used contrast agents used during MRIs, as is Magnevist, Gadavist, and Dotarem. If you take into consideration the compounds we are exposed to almost every day that are already contributing to brain degeneration (i.e., aluminum), you can see why you must be constantly aware of what is being offered to you by medical professionals. Ask questions and research any drugs that you are being given, especially if you are having an MRI, and work with your doctor to find safer methods for obtaining your health goals.

Brain Scans Catch Autism Months Before Symptoms Appear

The symptoms of autism generally begin to emerge in a person between 12 and 18 months of age. Oftentimes, babies develop normally until this age, but then they start regressing and lose skills. Now, a recent study suggests it may be possible to spot autism on an MRI scan months before symptoms start. [1]


Geraldine Dawson, a clinical psychologist and autism researcher at Duke University who was not involved in the new work, says:


“We’re learning that there are biological changes that occur at [the time] or before the symptoms start to emerge. It’s the ability to detect autism at its very earliest stages that’s going to allow us to intervene before the full syndrome is manifest.”


Read: New Scientific Discovery Could Make it Easier to Diagnose, Treat Autism


For the study, researchers conducted MRI scans on 150 children, 3 times: at 6 months old, 1 year, and 2 years. More than 100 of those children were at high risk for autism because they had an older sibling diagnosed with the disorder. Infants with older siblings who have autism have about a 1 in 5 chance of developing autism spectrum disorder (ASD).


The team found that 8 times out of 10, they could correctly predict which children would go on to develop autism based on the faster growth rate of the surface areas of their brains. They detail their findings in the journal Nature. [1] [2]


Source: ABC News – A 2011 study found that people with certain types of autism have bigger brains.

Washington University child psychiatrist Dr. Kelly Botteron, explains:


“It was basically 80, 85% predictive of being able to basically make a diagnosis based on just their MRI scan changes from 6 to 12 to 24 months.” [3]




The study’s lead author, Heather Hazlett, a psychologist at the University of North Carolina’s Carolina Institute for Developmental Disabilities (CIDD), says that enlargement of the brain seemed to correlate with the onset of symptoms, but more research is needed. The study was small, and doctors shouldn’t start conducting MRIs on children in an effort to diagnose them. [1]

Still, if the findings can be recreated in a larger study, MRI could become a new diagnostic tool for high-risk children before their symptoms begin, giving parents the opportunity to start treating their child at a time when treatment will be possibly most effective. We just have to be careful with recommending such measures, or we could see issues similar to those arising from mammograms (causing issues due to being unnecessarily overused). Currently, the average age of diagnosis is about 4 years. [2]


Botteron says:


“There’s pretty good evidence that the earlier we can make a diagnosis and begin interventions, even things like speech therapy, physical therapy, occupational therapy, kinds of behavioral interventions that we can have a much better long-term outcome.” [3]


Some of those interventions and treatments could include “hyper-parenting,” McPartland explains, meaning that a child headed for autism might benefit from more parental interaction such as cooing, singing, and laughing. He says:


“Supersaturate a child’s environment with social information as much as you can. And hope that it takes.” [1]

Chart Of The Week: The Exodus Begins

In March, hordes of "triggered" and "fearful" liberals began to investigate just what it would take to leave the country if - horror of horrors - Donald Trump should win the US presidential election. As the following chart shows, that "blip" of search hysteria appears to have been nothing compared to the overwhelming exodus that just occurred...



Of course, this has not gone unnoticed by the Canadians (who emigration website crashed on Wednesday), as Jim Quinn previously wrote, the flood of Trump-fearing American liberals sneaking across the border into Canada has intensified in the past week. The Republican presidential campaign is prompting an exodus among left-leaning Americans who fear they’ll soon be required to hunt, pray, pay taxes, and live according to the Constitution.





Canadian border residents say it’s not uncommon to see dozens of sociology professors, liberal arts majors, global-warming activists, and “green” energy proponents crossing their fields at night.



“I went out to milk the cows the other day, and there was a Hollywood producer huddled in the barn,” said southern Manitoba farmer Red Greenfield, whose acreage borders North Dakota. “He was cold, exhausted and hungry, and begged me for a latte and some free-range chicken. When I said I didn’t have any, he left before I even got a chance to show him my screenplay, eh?”



In an effort to stop the illegal aliens, Greenfield erected higher fences, but the liberals scaled them. He then installed loudspeakers that blared Rush Limbaugh across the fields, but they just stuck their fingers in their ears and kept coming. Officials are particularly concerned about smugglers who meet liberals just south of the border, pack them into electric cars, and drive them across the border, where they are simply left to fend for themselves after the battery dies.



“A lot of these people are not prepared for our rugged conditions,” an Alberta border patrolman said. “I found one carload without a single bottle of Perrier water, or any gemelli with shrimp and arugula. All they had was a nice little Napa Valley cabernet and some kale chips. When liberals are caught, they’re sent back across the border, often wailing that they fear persecution from Trump high-hairers.



Rumors are circulating about plans being made to build re-education camps where liberals will be forced to drink domestic beer, study the Constitution, and find jobs that actually contribute to the economy.



In recent days, liberals have turned to ingenious ways of crossing the border. Some have been disguised as senior citizens taking a bus trip to buy cheap Canadian prescription drugs. After catching a half-dozen young vegans in blue-hair wig disguises, Canadian immigration authorities began stopping buses and quizzing the supposed senior citizens about Perry Como and Rosemary Clooney to prove that they were alive in the ’50s.



“If they can’t identify the accordion player on The Lawrence Welk Show, we become very suspicious about their age,” an official said.



Canadian citizens have complained that the illegal immigrants are creating an organic-broccoli shortage, are buying up all the Barbara Streisand CD’s, and are overloading the internet while downloading jazzercise apps to their cell phones.



“I really feel sorry for American liberals, but the Canadian economy just can’t support them,” an Ottawa resident said. “After all, how many art-history majors does one country need?"



Finally, for those still thinking of leaving, our exclusive “Canadian insider” offered these tips and answers about making the move to Canada and what you can expect when you arrive:


1. Are Canadians as polite as the jokes say?


In fact they are. One joke that even Canadians laugh at goes, “How do you get 47 Canadians out of the pool as quickly as possible?” The answer: simply yell, “Get out of the pool!”


2. Is the weather in Canada as bad as the jokes say?


No; it is actually worse. The beautiful East Coast becomes an ice cube in the winter—an endurance test equaled only by the weather in the capital, Ottawa, where the main distraction (aside from watching your breath freeze) is skating on the central canal, which freezes solid during winter. The prairies are no better. The outdoor parking spots accompanying most condos and hi-rises each have a built-in electrical outlet. No, not for your orbital buffer; they’re for your block heater. (If you don’t know what a block heater is, perhaps the Dominican Republic should really be your first choice for bugging out…?)


3. Of course, there is always Vancouver, which experiences the best winters in the country (like Seattle, but with fewer serial killings).


Keep in mind, however, that Vancouver currently has the largest housing bubble on the planet. (Source: “This is Freaking Nuts — House sells $750K above Asking,” Zerohedge, March 1, 2016.)


4. Canada has cross-country “value added tax” (VAT), called HST, that can add about 13% to a typical purchase in the mere blink of an eye.


If you are in business, you may be able to reclaim it. Most Canadians just pay it. Americans will find this unsettling. Of course, the whole idea of a VAT is that it theoretically obviates the need for income tax. Unfortunately Canada has not figured this out yet. They introduced income tax right after WWI, swore it was just temporary, and yet it is still here…? If, however, you are seeking the comfort and nostalgia of politicians who say one thing and then do another, Canada could be a dream come true.


5. Speaking of politics, the wise voters of Canada just threw out the most conservative leader in decades (that is “conservative” with BOTH a small “c” and a capital “C”).


This was mainly because they were bored with his conservatism, and (the irony!) they felt he was too close to the U.S.


6. Social medicine will be a kick if you are making the journey north.


It has its plusses and minuses. If you are in dire need, it is there. I have a friend who recently received a lung transplant, did not pay a nickel, and now loves Canada so much he moved back to Toronto from the Czech Republic. On the other hand, if you are looking for a simple MRI in a non-urgent situation, be prepared to wait several months or (more irony!) be prepared to cross into a U.S. border town and pony up cold hard cash.


7. Supermarkets will be a shocker.


Imagine that 70% of all the products you have come to know and love disappeared in the blink of an eye, like in a sci-fi movie, and, in many cases, they were replaced by brands you have never heard of. Your first time grocery shopping may possibly bring a tear to your eye. Good news? They do stock Kleenex, just like in the U.S.


8. No, you don’t have to learn French, in spite of the millions of dollars a year Canadians spend translating and labeling everything that moves or squeaks into the official “second language.”


Learning French is mainly useful only if you plan to live in Quebec or run for federal office. And if you learned history via U.S. textbooks, be prepared for some revisionism. Turns out that France did not lose the war for Canada to the Brits at the Battle of the Plains of Abraham. It was actually a “draw.” (Luckily, nobody bothered to tell the British or every province in Canada would have two tax systems and two levels of government, just like those freethinkers in Quebec.)


9. The thing you will notice the most?


Well, the whole money thing will be uncomfortable. First of all, everything in Canada costs more, ceteris paribus, than the equivalent item in the U.S., even before taxes. Why? Mainly because of the higher costs of labeling and moving goods in the sparser geography (hey! those French labels don’t put themselves on the items, do they…). Next, if you factor in the weaker loonie, well, let’s just say that as a Canadian newbie, your first experience with socialized medicine might be for anti-depressants. The good news? The doctor’s visit, and part of the cost of your meds, will be picked up by the very same country that depressed you in the first place!
