What's the best way to keep your brain sharp?

When most of us think about keeping our brains flexible and powerful, most of us probably think of things like brainteasers...

...or crosswords.

Oh my God, they're doing it in pen. Hard. Core.

And brain challenges can help, although not every puzzle is created equal (some studies suggest that doing a bunch of crosswords might just make you better at crosswords, for example).

But maybe we need some of THIS added to the mix:

Don't bother him, he's exercising his brain.

Exercise won't just make you swole, a new study shows it also keeps your brain young.

As we get older, our brains tend to slow down a bit, but a study published in Neurology showed that exercise keeps our brains quick, sharp, and powerful.

The study followed about 900 older people over the course of many years. The researchers judged how much exercise the people were getting, then over the course of more than a decade, they judged their mental capabilities using memory and logic tests. They even used MRIs.

At the end, the study showed people who intensely exercised had brains that looked 10 years younger than their peers.

Those people were both quicker at figuring things out and had better memories. The researchers note that it wasn't just any exercise — the benefit came for the people who got regular moderate to intense exercise, like running or aerobics.

The researchers did caution that they can't draw a direct 1:1 relationship between exercise and brain aging, but exercise carries a lot of other benefits that might come around to helping our brains anyway. Exercise can help fight off hypertension (which can affect our brains) and decrease stress (which is a good thing all around). Some studies have even suggested exercise can make your brain bigger by volume!

Go for the gold!

Brain training.

So the next time you think about staying sharp, it might be time to put down the crossword puzzle and break out those running shoes.

Between the new normal that is working from home and e-learning for students of all ages, having functional electronic devices is extremely important. But that doesn't mean needing to run out and buy the latest and greatest model. In fact, this cycle of constantly upgrading our devices to keep up with the newest technology is an incredibly dangerous habit.

The amount of e-waste we produce each year is growing at an increasing rate, and the improper treatment and disposal of this waste is harmful to both human health and the planet.

So what's the solution? While no one expects you to stop purchasing new phones, laptops, and other devices, what you can do is consider where you're purchasing them from and how often in order to help improve the planet for future generations.

Sir David Attenborough has one of the most recognized and beloved voices in the world. The British broadcaster and nature historian has spent most of his 94 years on Earth educating humanity about the wonders of the natural world, inspiring multiple generations to care about the planet we all call home.

And now, Attenborough has made a new name for himself. Not only has he joined the cool kids on Instagram, he's broken the record for reaching a million followers in the shortest period. It only took four hours and 44 minutes, which is less time than it took Jennifer Aniston, who held the title before him at 5 hours and 16 minutes.

A day later, Attenborough is sitting at a whopping 3.4 million followers. And he only has two Instagram posts so far, both of them videos. But just watch his first one and you'll see why he's attracted so many fans.

There are very few people who have had quite as memorable a life as Arnold Schwarzenegger. His adult life has played out in four acts, with each one arguably more consequential than the last.

And now Schwarzenegger wants to play a role in helping America, his adopted home, ensure that our 2020 election is safe, secure and available to everyone willing and able to vote.

Shortly after immigrating to America, Schwarzenegger rose up to become the most famous bodybuilder in history, turning what was largely a sideshow attraction into a legitimate sport. He then pivoted to an acting career, becoming Hollywood's highest paid star in a run that spanned three decades.

One night in 2018, Sheila and Steve Albers took their two youngest sons out to dinner. Their 17-year-old son, John, was in a crabby mood—not an uncommon occurrence for the teen who struggled with mental health issues—so he stayed home.

A half hour later, Sheila's started getting text messages that John wasn't safe. He had posted messages with suicidal ideations on social media and his friends had called the police to check on him. The Albers immediately raced home.

When they got there, they were met with a surreal scene. Their minivan was in the neighbor's yard across the street. John had been shot in the driver's seat six times by a police officer who had arrived to check on him. The officer had fired two shots as the teen slowly backed the van out of the garage, then 11 more after the van spun around backward. But all the officers told the Albers was that John had "passed" and had been shot. They wouldn't find out until the next day who had shot and killed him.
