Want to Live 12 Years Longer? A 30-Year Study Says Embracing an Optimism Mindset Is a Major Predictor of Longevity
Even better news: Since only 25 percent of your level of optimism is hereditary, becoming more positive is largely something you control. Here's how.
How to Be More Optimistic
Research shows that approximately 25 percent of our optimism set-point is genetic. That means 75 percent of your level of optimism can be shaped and learned.
In one study, participants who spent five minutes a day for two weeks imagining their "best possible self" (in terms of professional, relationship, and personal goals) experienced significant increases in optimism.
If visualization isn't your thing -- it definitely isn't mine -- try another approach. If, as Jim Rohn says, we are the average of the five people we spend the most time with, simply spend more time with optimistic people. They'll be more encouraging. They'll be more supportive. Their enthusiasm will naturally rub off on you.
If spending time in groups isn't your thing -- it kind of isn't mine -- then take a step back and think about your mindset. Generally speaking, people fall into two camps. Those with a fixed mindset believe that intelligence, ability, and skill are inborn and relatively fixed. That we are what we were born with.
Someone with a fixed mindset might say, "I didn't handle that well. I'm not cut out to be a leader."
People with a growth mindset believe that intelligence, ability, and skill can be developed through effort. That we are what we work to become. Someone with a growth mindset might say, "I didn't handle that well, but next time I'll make sure I'm more prepared."
People who embrace a growth mindset believe success is based on effort and application, not innate talent.
That makes YOU more optimistic.
And will help YOU live a longer, healthier life.
Music Could Be the Next Best Treatment for Pain
It may come as a surprise, but music is a tried-and-true therapy for healing in the eyes of science. Numerous studies support its benefits in combination with other treatments, as well as on its own. Still, we don’t know much about its mechanism—we know that sound can provide physiological benefits, but not how.
A new study in mice, published Thursday in the journal Science, reveals a recipe for leveraging music as a potential pain reliever and providing a low-cost, widely accessible alternative to traditional pharmaceuticals.
A team of neuroscientists from China and the U.S. injected the hind paws of lab mice with complete Freund's adjuvant, a solution that causes inflammation and pain. Then they prodded the hind paws and observed the threshold at which the mice flinched—providing a measurement of each animal’s tolerance for pain.
The team went on to play sounds at levels slightly higher than background noise and observed what kinds of effects these sounds had on the mice’s pain tolerance. It seems like the mice weren’t music snobs: They reacted equally to classical music, dissonant music, and white noise when each was played 5 decibels louder than ambient noise.
Whatever the music was, the overall effect was remarkable: The sounds being played led to significantly lower pain levels for the mice, a result that persisted even two days later.
“In the future, these findings could spur the development of alternative interventions for treating pain,” the authors wrote in the new paper.
Once they had evidence that the music therapy worked, the researchers peered into the mice’s brains and recorded the regions that lit up when they played the soothing sounds. They traced the effects through regions called the neocortex, thalamus, and brainstem to show how the music competed for airtime in the brain with pain signals from the paw.
According to an accompanying perspective article in Sciencewritten by Heidelberg University biologists Rohini Kuner and Thomas Kuner, previous explanations for the pain-relieving properties of music focused on sounds’ ability to distract listeners. While sound “likely contributes to distraction,” they wrote that the study details a new and distinct pathway for pain suppression.
They also speculated that the secret sauce that explains the 5-decibel effect was its ability to trigger defensive instincts in the mice. If so, a fight-or-flight response would have lowered their perceptions of pain as the mice focused on more pressing concerns, like avoiding a potential threat. “From an evolutionary perspective, it makes sense that sound-driven defense behaviors are acutely accompanied by pain suppression,” the Kuners wrote.
Even so, we need to study this phenomenon in more depth before we can start firing off pain-relieving noises to patients in need.
“Using rodents to study how music and sound are related to pain presents major challenges, not least because it is unknown how animals perceive music,” the Kuners wrote.
On this point, the Chinese and American team seems to agree. “The neural mechanisms underlying music-induced analgesia in humans are doubtlessly more complicated than those revealed in mice,” they wrote.
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.
Americans use five times the amount of water that Europeans use.
I Study Cognition & This Is How To Know How "Old" Your Brain Is
October 25, 2022
Our editors have independently chosen the products listed on this page. If you purchase something mentioned in this article, we may earn a small commission.
We know that our brains are often not the same age as our chronological age. For instance, there is a group of people called SuperAgers, who are in their eighties and beyond but have the cognitive function of those decades younger1. Conversely, it's possible for your brain to be older than your chronological age. Obviously, that's not something you want!
So how old is your brain?
While there's no test you can take at home to definitively say how "old" or "young" your brain is, we can think of a young and healthy brain as being at peak function. And, most often, peak brain function is associated with a sharp memory. As we get older, it can be difficult to remember names, faces, events, something we just read, or what we ate.
In younger brains, the process called neural differentiation is efficient and robust. In this process, specific brain cells are tasked to remember certain types of information, such as faces. As we age, that process deteriorates, so the cells lose their specificity and do not function as well. Instead of just focusing on faces, they try to remember other types of information as well. For a SuperAger, neural differentiation is akin to that of a twenty-five-year-old. That's part of the reason why a SuperAger has the memory performance of a twenty-five-year-old.
So what else are the secrets of these SuperAgers with robust memory—and all those with brain ages younger than their chronological age? A study published in 2021 uncovered some surprising answers. Over eighteen months, the study followed 330 people, referred to as SuperAgers, who were 100 years or older; the researchers found no decline in most areas of memory or cognitive abilities2.
While a year and a half might not sound like a long time, once a person reaches the century mark, two years for them is like twenty-five years for a seventy-five-year-old in terms of brain health. For example, the risk for developing dementia3 increases by 60 percent every two years after the age of 100, while it takes twenty-five years for a 75-year-old's risk of dementia to increase by the same amount. In other words, twenty-five years of risk is compressed into two years after the age of 100.
How to maintain a younger brain.
So, what is the secret of these mentally strong centenarians? You might be tempted to guess "genes." While genes can definitely play a role, 16.8 percent of the people in the study had genes that are known to raise the risk of Alzheimer's, and they did not develop the disease. What seemed to be a key piece of the puzzle was lifestyle!
One key factor was that they kept learning new things throughout their life. Remember, your memories are housed in those connections between your brain cells. Think of your brain like a bank account; the more deposits we make, the less our net worth is affected by withdrawals. We make deposits (new connections) by learning new things; as we age and naturally lose some of those connections, there are simply more remaining. There's a Spanish saying: "Learn one new thing each day." This simple advice is an excellent first rule for brain health—learning new information or a new skill keeps your brain young. So, if you are learning something new by reading this right now, you are doing one of the most important things for your brain.
A helpful exercise.
While we are not at the point where every person can slide into a brain scanner and find out their brain age, here are just a couple of factors that can help give you a sense of your brain age. Ask yourself the following five questions.
To remember these five questions, I created the mnemonic B.R.A.I.N., where the first letter of each question corresponds to a letter in the word “brain.”
*Balance and coordination: How well can I move and maintain balance4?
*Recall: How well can I remember important information5?
*Ability to get through the day or executive functioning: How well can I manage my day?
*Intensity: How fast can I walk? Faster walking speed is associated with a more youthful brain.
*Number: What's your age number in terms of how old do you feel? People who say they feel younger tend to have younger-looking brains8.
Use this B.R.A.I.N. mnemonic to quiz yourself tomorrow on these five questions. Mnemonics are an excellent way to remember information. Since recall is a use-or-lose-it skill and one of the five questions, here's a fun chance to practice.
Of course, none of these questions can replace an actual brain scan and comprehensive evaluation by a neurologist. Still, these fundamental categories can help us get a sense of brain age. It is important to note that simply determining someone's brain age by brain scan is also not without complexity and controversy9.
For example, there is the issue of which part of the brain and which biomarkers, such as white or gray matter, iron deposits, and volume, to investigate or prioritize. Be wary of a private clinic offering to tell you your brain age, especially for a hefty fee, as at this point this tool is primarily being used accurately at large research institutions. For that matter, be wary if it's an offer from a guy in a van for a bargain fee.
In all seriousness, determining brain age using cutting-edge imaging technology has become an emerging and powerful tool in research studies at large institutions10 to understand health, disease, and mortality. Remember, it is not just one of these factors but a combination that determines brain age.

The Ig Nobel Prize (/ˌɪɡnoʊˈbɛl/ IG-noh-BEL) is a satiric prize awarded annually since 1991 to celebrate ten unusual or trivial achievements in scientific research, its stated aim being to "honor achievements that first make people laugh, and then make them think." The name of the award is a pun on the Nobel Prize, which it parodies, and on the word ignoble.
Organized by the scientific humor magazine Annals of Improbable Research (AIR), the Ig Nobel Prizes are presented by Nobel laureates in a ceremony at the Sanders Theater, Harvard University, and are followed by the winners’ public lectures at the Massachusetts Institute of Technology.
Sherlock Holmes' famous memory trick really works
Sherlock Holmes remembers everything by imagining that he's storing bits of information in a "memory palace," a technique that originated in ancient Greece. Now, researchers have found that this method really does work to create long-lasting memories.
