Our time is precious, isn’t it? We don’t want to waste it by spending hours scrolling through the endless source of information that is the internet, aiming to find interesting pieces of trivia to have on hand at our next dinner party. What we do want is to spend this free time wisely, so carefully curated accounts like the 'Not Common Facts' are the perfect outlets to help our mission. This page on Instagram is like a breath of fresh air where people can find concise and easily digestible information that is also fun to read through.

But as much as it is delightful to discover lesser-known historical and scientific details about our world, acquiring new knowledge is much more than just pure entertainment. According to an article by Harvard Health Publishing, learning and mastering new activities trains our brains and gets our minds going. The researchers explained that our mental muscles can grow and learn as we get older, but they can only do that if we give them something to work with, like picking up a new hobby or performing a challenging activity.

"Eventually, your cognitive skills will wane and thinking and memory will be more challenging, so you need to build up your reserve," Dr. John N. Morris, director of social and health policy research at the Institute for Aging Research, said. "Embracing a new activity that also forces you to think and learn and requires ongoing practice can be one of the best ways to keep the brain healthy."

The good news is that we can pick out any new activity we can think of, as long as it follows three important guidelines that would maximize brain training. The first one, Dr. Morris stated, is that it must be challenging. Although if you can’t think of something new that would pique your interest, you can spend time improving your existing skills. "You don't have the challenge of learning something new, but rather the challenge of increasing your skill set and knowledge," he added.

Another thing to keep in mind is the complexity of the activity. Not only does it make us more excited to delve deeper into the subject, but it also accelerates problem-solving and critical thinking. And lastly, you need to practice it to make it permanent, just as with everything else in life. "You can't improve memory if you don't work at it. The more time you devote to engaging your brain, the more it benefits," Dr. Morris said. "It is the constant repetition of working to improve, and not the quest for mastery, that can have the greatest impact."

We previously had a chat with Barbara Oakley, Ph.D., a professor of engineering at Oakland University in Rochester and author of Learn Like a Pro: Science-Based Tools to Become Better at Anything, who agreed with Morris’ line of thinking.

"New knowledge serves as a sort of mental trellis that allows new neurons to survive, thrive, and grow," she told Bored Panda. When we’re not engaged in learning, these "new neurons, instead of nestling into your neural lattice, will wither and die. And you can find yourself becoming less flexible in your thinking as you increasingly rely on older neurons," the professor added. 

When you wish to become better at educating yourself, setting a goal is of the utmost importance. After all, when you have your eyes on the prize, it encourages you to keep going and helps a lot with the whole process. "You might set a goal of reading 20 pages a day of a book, which can amount to 15 books or more each year," Oakley suggested. "And there are wonderful online courses on learning!" 

The professor herself teaches courses online like Learning How to Learn: Powerful mental tools to help you master tough subjects. According to her, online learning is great since we can access these lessons from any corner of the world, and they can add a lot to our educational journey. "You’ll see that many of these online courses are divided into 'chunks' of material that you can reasonably cover each week," Oakley told us. "And you’ll get weekly reminder emails to help keep you on track." 

Oakley pointed out that virtually any kind of new learning helps keep our brains fresh, as long as it is challenging and complicated enough to increase our intelligence. "Whether it’s a new language, bringing back your rusty math skills, improving your ability to code, or taking up a new sport," the professor provided a few examples. And if you’re not sure where to start, picking up a book and reading a certain number of pages is a great way to feed your curiosity.

"If you want to make your new learning 'stick' even better — and reduce mental fog — add some exercise to your life," Oakley continued. "Exercise helps produce a chemical, BDNF, that serves as a sort of fertilizer for newer and stronger neural connections in the brain. In other words, BDNF helps you focus and remember better!"

When asked whether the internet is a good tool for learning new facts and building up our knowledge, she told us that it gives us incredible opportunities to learn from some of the best teachers in the world. "Athlete Julius Yego, for example, couldn’t find top javelin throwing coaches in his native Kenya and couldn’t afford to travel overseas to train," Oakley said. "So he started watching YouTube videos." Surprisingly, by watching tutorials online and practicing on his own, "he became the world champion in the javelin!"

Also, if you want to become better at remembering the things you recently learned, the professor explained that the best way "is to use what psychologists call 'retrieval practice.'" She noted that this simply means retrieving information from your brain. "That is, checking to see if you’ve got that information stored inside you."
