If you're a chronic worrier, here's what you should know about your brain.

I worry a lot. I worry about my friends, my health, my planet. Heck, I worry about worrying too much.

It can keep me up at night wondering whether I've ruined my shoes by buying shoe polish, or it can make me read that one email 10 times before sending it off. It can be tempting to hate my brain for worrying so much.


Maybe I shouldn't be so harsh on myself. Every human being worries. And it turns out, worrying can have some surprising upsides, as professor Kate Sweeny recently wrote. So if you're the kind of person who worries about worrying, here are two big things to remember, courtesy of Sweeny:

1. Worrying is a track coach, keeping our brains active and motivated.

Nobody would hate their brains for making them feel scared when there's a big, obvious danger. Like an angry tiger. Or a bear. Or an angry tiger riding a bear. In that case, we need an immediate motivator for an immediate problem.

But our brains need a subtler response to subtler problems. Worry and anxiety can help our brains recognize and focus on long-term problems or motivate us to make better choices, like wearing our seat belts or applying sunscreen to avoid skin cancer.

2. Worrying is an emotional cushion, making our highs higher and lows not as bad.

Though worrying itself is unpleasant, it can help balance out our other emotions. One study showed the BBC television sitcom "Fawlty Towers" got funnier after watching a tense horror movie.

On the flip side, if things end up going south, your brain has already prepared itself. So worrying can be an emotional win-win.

But like all things, there's a right amount.

While a little worry can help us stay motivated, too much can paralyze us and can be a sign of anxiety disorders. If that's what's going on, taking a break from Facebook, practicing meditation, exercising, and talking with a therapist can all help reduce anxiety.

So, biologically, don't hate your brain for worrying.

Worry can be stressful. It's not fun to stay awake thinking about what you're going to say to your boss on Monday, whether you're eating right, or whether you're being a good friend. You might find yourself beset by worries at the worst time.

And that's OK. We can't always control our brains, but we worrywarts don't always need to feel bad for worrying. Sometimes it's our brain just helping us out.

When a pet is admitted to a shelter it can be a traumatizing experience. Many are afraid of their new surroundings and are far from comfortable showing off their unique personalities. The problem is that's when many of them have their photos taken to appear in online searches.

Chewy, the pet retailer who has dedicated themselves to supporting shelters and rescues throughout the country, recognized the important work of a couple in Tampa, FL who have been taking professional photos of shelter pets to help get them adopted.

"If it's a photo of a scared animal, most people, subconsciously or even consciously, are going to skip over it," pet photographer Adam Goldberg says. "They can't visualize that dog in their home."

Adam realized the importance of quality shelter photos while working as a social media specialist for the Humane Society of Broward County in Fort Lauderdale, Florida.

"The photos were taken top-down so you couldn't see the size of the pet, and the flash would create these red eyes," he recalls. "Sometimes [volunteers] would shoot the photos through the chain-link fences."

That's why Adam and his wife, Mary, have spent much of their free time over the past five years photographing over 1,200 shelter animals to show off their unique personalities to potential adoptive families. The Goldbergs' wonderful work was recently profiled by Chewy in the video above entitled, "A Day in the Life of a Shelter Pet Photographer."

Vanna White appeared on "The Price Is Right" in 1980.

Vanna White has been a household name in the United States for decades, which is kind of hilarious when you consider how she gained her fame and fortune. Since 1982, the former model and actress has made millions walking back and forth turning letters (and later simply touching them—yay technology) on the game show "Wheel of Fortune."

That's it. Walking back and forth in a pretty evening gown, flipping letters and clapping for contestants. More on that job in a minute…

As a member of Gen X, television game shows like "Wheel of Fortune" and "The Price is Right" send me straight back to my childhood. Watching this clip from 1980 of Vanna White competing on "The Price is Right" two years before she started turning letters on "Wheel of Fortune" is like stepping into a time machine. Bob Barker's voice, the theme music, the sound effects—I swear I'm home from school sick, lying on the ugly flowered couch with my mom checking my forehead and bringing me Tang.

This video has it all: the early '80s hairstyles, a fresh-faced Vanna White and Bob Barker's casual sexism that would never in a million years fly today.
