We didn't always turn left the way we do now. What changed?

We didn't always turn left the way we do now. What changed?

Unless you're a child, New York City resident, or UPS driver, chances are you've made a left turn in your car at least once this week.

Chances are, you didn't think too much about how you did it or why you did it that way.

You just clicked on your turn signal...

...and turned left.

The New York State Department of Motor Vehicles instructs drivers to "try to use the left side of the intersection to help make sure that you do not interfere with traffic headed toward you that wants to turn left," as depicted in this thrilling official state government animation:

Slick, smooth, and — in theory — as safe as can be.

Your Drivers Ed teacher would give you full marks for that beautifully executed maneuver.

Before 1930, if you wanted to hang a left in a medium-to-large American city, you most likely did it like so:

Instead of proceeding in an arc across the intersection, drivers carefully proceeded straight out across the center line of the road they were turning on and turned at a near-90-degree angle.

Often, there was a giant cast-iron tower in the middle of the road to make sure drivers didn't cheat.

These old-timey driving rules transformed busy intersections into informal roundabouts, forcing cars to slow down so that they didn't hit pedestrians from behind.

Or so that, if they did, it wasn't too painful.

"There was a real struggle first of all by the urban majority against cars taking over the street, and then a sort of counter-struggle by the people who wanted to sell cars," explains Peter Norton, Associate Professor of History at the University of Virginia and author of "Fighting Traffic: The Dawn of the Motor Age in the American City."

Norton posted the vintage left-turn instructional image, originally published in a 1919 St. Louis drivers' manual — to Facebook on July 9. While regulations were laxer in suburban and rural areas, he explains, the sharp right-angle turn was standard in nearly every major American city through the late '20s.

“That left turn rule was a real nuisance if you were a driver, but it was a real blessing if you were a walker," he says.

Early traffic laws focused mainly on protecting pedestrians from cars, which were considered a public menace.

For a few blissful decades after the automobile was invented, the question of how to prevent drivers from mowing down all of midtown every day was front-of-mind for many urban policymakers.

Pedestrians, Norton explains, accounted for a whopping 75 percent of road deaths back then. City-dwellers who, unlike their country counterparts, often walked on streets were predictably pretty pissed about that.

In 1903, New York City implemented one of the first traffic ordinances in the country, which codified the right-angle left. Initially, no one knew or cared, so the following year, the city stuck a bunch of big metal towers in the middle of the intersections, which pretty well spelled things out.

Some cities installed unmanned versions, dubbed "silent policemen," which instructed motorists to "keep to the right."

Drivers finally got the message, and soon, the right-angle left turn spread to virtually every city in America.

Things were pretty good for pedestrians — for a while.

In the 1920s, that changed when automobile groups banded together to impose a shiny new left turn on America's drivers.

According to Norton, a sales slump in 1922 to 1923 convinced many automakers that they'd maxed out their market potential in big cities. Few people, it seemed, wanted to drive in urban America. Parking spaces were nonexistent, traffic was slow-moving, and turning left was a time-consuming hassle. Most importantly, there were too many people on the road.

In order to attract more customers, they needed to make cities more hospitable to cars.

Thus began an effort to shift the presumed owner of the road, "from the pedestrian to the driver."

"It was a multi-front campaign," Norton says.

The lobbying started with local groups — taxi cab companies, truck fleet operators, car dealers associations — and eventually grew to include groups like the National Automobile Chamber of Commerce, which represented most major U.S. automakers.

Car advocates initially worked to take control of the traffic engineering profession. The first national firm, the Albert Erskine Bureau for Street Traffic Research, was founded in 1925 at Harvard University, with funds from Studebaker to make recommendations to cities on how to design streets.

Driving fast, they argued, was not inherently dangerous, but something that could be safe with proper road design.

Drivers weren't responsible for road collisions. Pedestrians were.

Therefore, impeding traffic flow to give walkers an advantage at the expense of motor vehicle operators, they argued, is wasteful, inconvenient, and inefficient.

Out went the right-angle left turn.

Industry-led automotive interest groups began producing off-the-shelf traffic ordinances modeled on Los Angeles' driver-friendly 1925 traffic code, including our modern-day left turn, which was adopted by municipalities across the country.

The towering silent policemen were replaced by dome-shaped bumps called "traffic mushrooms," which could be driven over.

Eventually the bumps were removed altogether. Barriers and double yellow lines that ended at the beginning of an intersection encouraged drivers to begin their left turns immediately.

The old way of hanging a left was mostly extinct by 1930 as the new, auto-friendly ordinances proved durable.

So ... is the new left turn better?

Yes. Also, no.

It's complicated.

The shift to a "car-dominant status quo," Norton explains, wasn't completely manufactured — nor entirely negative.

As more Americans bought cars, public opinion of who should run the road really did change. The current left turn model is better and more efficient for drivers — who have to cross fewer lanes of traffic — and streets are less chaotic than they were in the early part of the 20th century.

Meanwhile, pedestrian deaths have declined markedly over the years. While walkers made up 75% of all traffic fatalities in the 1920s in some cities, by 2015, just over 5,000 pedestrians were killed by cars on the street, roughly 15% of all vehicle-related deaths.

There's a catch, of course.

While no one factor fully accounts for the decrease in pedestrian deaths, Norton believes the industry's success in making roadways completely inhospitable to walkers helps explain the trend.

Simply put, fewer people are hit because fewer people are crossing the street (or walking at all). The explosion of auto-friendly city ordinances — which, among other things, allowed drivers to make faster, more aggressive left turns — pushed people off the sidewalks and into their own vehicles.

When that happened, the nature of traffic accidents changed.

"Very often, a person killed in a car in 1960 would have been a pedestrian a couple of decades earlier," Norton says.

We still live with that car-dominant model and the challenges that arise from it. Urban design that prioritizes drivers over walkers contributes to sprawl and, ultimately, to carbon emissions. A system engineered to facilitate auto movement also allows motor vehicle operators to avoid responsibility for sharing the street in subtle ways. The Centers for Disease Control and Prevention lists three tips to prevent injuries and deaths from car-human collisions — all for pedestrians, including "carrying a flashlight when walking," and "wearing retro-reflective clothing."

A Minneapolis Star-Tribune analysis found that, of over 3,000 total collisions with pedestrians (including 95 fatalities) in the Twin Cities area between 2010 and 2014, only 28 drivers were charged and convicted a crime — mostly misdemeanors.

Norton says he's encouraged, however, by recent efforts to reclaim city streets and make them safe for walkers.

That includes a push by groups like Transportation Alternatives to install pedestrian plazas and bike lanes and to promote bus rapid transit. It also includes Vision Zero, a safety initiative in cities across America, which aims to end traffic fatalities by upgrading road signage, lowering speed limits, and installing more traffic circles, among other things.

As a historian, Norton hopes Americans come to understand that the way we behave on the road isn't static or, necessarily, what we naturally prefer. Often, he explains, it results from hundreds of conscious decisions made over decades.

"We're surrounded by assumptions that are affecting our choices, and we don't know where those assumptions come from because we don't know our own history," he says.

Even something as mindless as hanging a left.

Three women, three MS journeys: How multiple sclerosis looks different for everyone

Gina, Nathalie and Helga share their reactions to being diagnosed with MS and how they stay informed and positive in the face of ever-changing symptoms.

Helga, Nathalie and Gina all have MS, and their experiences show how differently the disease can manifest.

True

It’s been 155 years since neurologist Jean-Martin Charcot gave the first lecture on a mysterious progressive illness he called “multiple sclerosis.” Since then, we’ve learned a lot. We know MS causes the immune system to attack healthy tissue, including damaging the brain and spinal cord. Resulting symptoms can be debilitating and include fatigue, blurred vision, memory problems and weakness. Huge advancements in our understanding of MS and its underlying causes, as well as treatment advances, have been made in the past few decades, but MS remains a complex and unpredictable reality for the 2.8 million+ people diagnosed around the world.

Ironically, the only real constant for people living with MS is change. There’s no set pattern or standard progression of the disease, so each person’s experience is unique. Some people with MS have mild symptoms that worsen slowly but sometimes improve, while others can have severe symptoms that drastically alter their daily lives.

All people with MS share some things in common, however, such as the need to stay informed on the ever-evolving research, find various lines of support and try to remain hopeful as they continue living with the disease.

To better understand what navigating life with MS really looks like, three women shared their MS stories with us. Their journeys demonstrate how MS can look different for different people and interestingly, how the language used to talk about the disease can greatly impact how people understand their realities.

Gina—Hamburg, Germany (diagnosed with relapsing multiple sclerosis in 2017)

When her youngest son was 4 months old, Gina started having problems with her eye. She’d soon learn she was experiencing optic neuritis—her first symptom of MS.

“Immediately after the diagnosis, I looked up facts on MS because I didn’t know anything about it,” Gina says. “And as soon as I knew what could really happen with this disease, I actually got scared.”

As her family’s primary income provider, she worried about how MS would impact her ability to work as a writer and editor. Her family was afraid she was going to end up in a wheelchair. However, for now, Gina’s MS is managed well enough that she still works full-time and is able to be active.

“When I tell somebody that I have MS, they often don't believe me the first time because I don't fulfill any stereotypes,” she says.

Overwhelmed by negative perspectives on living with MS, Gina sought support in the online MS community, which she found to be much more positive.

“I think it’s important to use as many positive words as you can when talking about MS.” It’s important to be realistic while also conveying hope, she says. “MS is an insidious disease that can cause many bad symptoms…that can be frightening, and you can't gloss over it, either.”

To give back to the online community that helped her so much, Gina started a blog to share her story and help others trying to learn about their diagnosis.

Though she deals with fatigue and cognitive dysfunction sometimes, Gina stays active swimming, biking, riding horses and playing with her sons, who are now 11 and 6.

Cognitive dysfunction is common in MS, with over half of people affected. It can impact memory, attention, planning, and word-finding. As with many aspects of MS, some people experience mild changes, while others face more challenges.

Gina says that while there’s still a lot of education about MS needed, she feels positive about the future of MS because there’s so much research being done.

Nathalie — Pennes Mirabeau, France (diagnosed with relapsing-remitting multiple sclerosis in 2002)

Nathalie was a teenager and a competitive athlete when she noticed her first symptoms of MS, but it would take four years of “limbo” before she was diagnosed.

“Ultimately, the diagnosis was more of a relief, than a shock,” she says. “Because when you have signs and you don’t know why, it’s worse than knowing, in the end, what you have.”

However, learning more about the disease—and the realities of disease progression—scared her.

“That glimpse of the future was direct and traumatic,” she says. Her neurologist explained that the disease evolves differently for everyone, and her situation might end up being serious or very mild. So, she decided to stop comparing herself to others with MS.

She said to herself, “We’ll see what happens, and you’ll manage it bit by bit.”

By 2005, Nathalie’s MS had progressed to the point of needing a wheelchair. However, that has not dampened her competitive spirit.

Nathalie began her international rowing career in 2009 and has won multiple world titles, including two Paralympic medals—silver in London and bronze in Tokyo. Now, at 42, she still trains 11 times a week. Fatigue can be a problem, and sometimes hard workouts leave her with muscle stiffness and shaking, but she credits her ongoing sports career for helping her feel in tune with her body’s signals.

“Over the years, I’ve learned to listen to my body, letting my body guide when I need to stop and take breaks,” she says.

Nathalie explains that she used to only look backwards because of the initial shock of her diagnosis. In time, she stopped thinking about what she couldn’t do anymore and focused on her future. She now lives in the following mindset: “Even when doors close, don’t miss out on those that open.” Instead of focusing on what she can’t do, she focuses on the opportunities she still has. Right now, this includes her training for the 2024 Paralympic Games in Paris, where she will compete for another rowing medal.

“I only go forward,” she says. “Well, I try, anyway…It’s easy to say, it’s not always easy to do. But that’s what I try to do.”

Helga—Johannesburg, South Africa (diagnosed with relapsing multiple sclerosis in 2010)

When Helga first started having balance issues and numbness in her feet, she chalked it up to her training as a runner. But when the numbness moved to her face, she knew something was wrong. She never guessed it was MS.

“When I was diagnosed, I felt completely overwhelmed and clueless,” Helga says. “I felt that I had nowhere near enough information. I did not know anything about the disease…I had no idea that it was going to be a process of continually monitoring and adjusting your lifestyle.”

In the beginning, Helga’s symptoms developed slowly, and she didn’t appear ill to others. She was even able to run for a few years after her diagnosis, but she couldn’t do marathons anymore, and she began to fall frequently due to balance issues and right-foot dragging. Then her cognition issues became more problematic, especially in her job as a trainer in a printing company.

“My executive function, decision-making and short-term memory were affected to the point that I was eventually medically unfit for work,” she says. She stopped working in 2017.

However, she didn’t stop living life. Even though she could no longer run, she continued to swim competitively. She got a Great Dane puppy and trained him as a service dog to help her walk. She also serves as vice chair of the patient support organization Multiple Sclerosis South Africa, and she advises others who have been diagnosed to join a patient advocacy group as soon as possible to get reliable information and meet others with MS.

Helga says she is “hopeful” about the future of MS. “I must say that I am so grateful that we have all the new medications available, because my life would not be the same if it wasn't for that,” she adds.

Part of how she manages her MS is by looking at the positives.

“If I could tell the world one thing about MS, it would be that MS is an incurable disease of the nervous system, but it's also the greatest teacher of valuing your health, family, friends, and managing change in your life,” she says. “My life is diversified in a way that I never, ever thought it would, and MS has been honestly the greatest teacher.”

Each MS journey is unique – with each person impacted experiencing different struggles, successes, and feelings as they manage this unpredictable disease. But the common thread is clear – there is a critical need for information, support, and hope. We are proud to participate in World MS Day and share these incredible stories of living life while living with MS.

Man lists things millennials grew up with that Gen Z would be outraged by

"Imagine telling them that their free unlimited minutes only started after 9:00 and on the weekends."

Things Gen Z would be outraged by that were normal for millennials.

There will likely always be some kind of playful generation war going on between older and younger generations. This time it's a millennial throwing what some may deem as truth bombs at Gen Z, seemingly unprompted. (Well, it could be that he's upset that Gen Z is getting all the credit for being tech savvy since the majority of his complaints were technology related.)

Dwight Thomas uploaded a video to TikTok listing things that millennials grew up with that the generation below him would be outraged by. As someone who would be considered an elder millennial by some people, I'd have to agree. The man makes some valid points about things we experienced as teenagers that would likely make teens today aggressively send out Change.org petitions.

"These new-age kids will never understand the struggle. Imagine telling them that their free unlimited minutes only started after 9:00 and on the weekends," Thomas says into the camera.

Man diagnosed as a sociopath answers people's questions.

The term "sociopath" is something that people don't often understand. The public's exposure to what a sociopath is generally comes from the media depictions, usually in some psychological thriller that portrays the villain as a manipulative, out-of-control killer. They slap the sociopath label on them either in the background information or through inference.

But what is a sociopath? For starters, it's not actually called "sociopath," though the terms are sometimes used interchangeably. The correct diagnosis is "antisocial personality disorder," and the Mayo Clinic defines it as, "a mental health condition in which a person consistently shows no regard for right and wrong and ignores the rights and feelings of others." While it's true that people who have this specific type of personality disorder often engage in criminal behavior, that doesn't mean they are going to be unpredictably violent.

Greg, a man who says he was diagnosed with sociopathy around the age of 21, sat down to answer people's questions about the disorder.

Street artist creates delightful 3D scenes in walls and walkways for everyone to enjoy

David Zinn's characters bring joy to the lucky folks that happen to come upon them before they wash away.

David Zinn creates art from what he sees everywhere he goes.

Street artists are a special breed. While "the art world" can sometimes be a snooty, elite place for those with means, street art is made for everyone. Sometimes that means large public murals, but street art can be small, too. In fact, some of the best street art is so small you might miss it if you're not paying attention. But those who are can discover some delightful surprises.

A size 21 Nike shoe made for Tacko Fall.

A local reporter at Hometown Life shared a unique and heartfelt story on March 16 about a mother struggling to find shoes that fit her 14-year-old son. The story resonated with parents everywhere; now, her son is getting the help he desperately needs. It's a wonderful example of people helping a family that thought they had nowhere to turn.

When Eric Kilburn Jr. was born, his mother, Rebecca’s OBGYN, told her that he had the “biggest feet I’ve ever seen in my life. Do not go out and buy baby shoes because they’re not gonna fit,’” Rebecca told Today.com. Fourteen years later, it’s almost impossible to find shoes that fit the 6’10” freshman—he needs a size 23.

Dramatic flying squirrel makes it look like the broom fell on it. Spoiler: It did not.

Animals can be far cleverer than we give them credit for, especially creatures we don't think of as having distinct personalities. Most of us expect cats and dogs to do show us their unique quirks, but what about a flying squirrel?

A video is making its way around the internet that has people giggling over the dramatic antics of a large pet flying squirrel. It includes no narration explaining what's happening and no context—it just shows a flying squirrel repeatedly faking its own death by broom.

That's right. Death by broom. And from the way it looks, the little bugger came up with the idea on its own and made multiple attempts to create a convincing crime scene.

This is one you just have to see.
