Everything I thought I knew about daylight saving time was wrong.

On the first Sunday in November, millions of people will set their clocks back an hour, marking the end of daylight saving time.

But while this autumnal tradition is engrained in our brains (and the extra hour of sleep circled on our calendars), most of us still don't know the scoop behind this semi-annual event.

But don't worry — I've got you. Let's take a few minutes out of your free hour to bust some myths about why we even have daylight saving time to begin with.

1. This is all because of farmers, right?

Historically, no. It turns out they kind of hate it.

Farmers are known the world over for two things: 1) getting up early and 2) working really hard. But, historically, it's the sun, not the clock that kicks off their day, so while people often blame daylight saving time on the farmers, that time jump is actually really disruptive for them. Shipments and orders still need to be filled at the same time, but there's one less hour of morning daylight to get things done.

What you might know is that farmers and the agriculture lobby actually fought to repeal daylight saving time in 1919, and it passed after Congress overrode President Woodrow Wilson's veto. But, as you may have guessed, that veto didn't last long.

2. OK, but springing forward saves a ton of energy and money, right?

Well, that was the plan anyway.

At the dawn of World War I, Germany thought, "Hey, we should turn the clocks back to help save coal and reduce lighting needs for the war effort." So, in 1916, they became the first country to give it a try (a few places in Canada had tried it before then as well). Before long, other countries were like, "Yeah, they're onto something." Daylight saving time arrived in the U.K. a few weeks later and then in the U.S. (as a temporary measure) in 1918.

After a few more experiments with daylight saving time, the U.S. made it permanent in 1966 with the Uniform Time Act.

But does it actually save us energy? Kind of.

In a 2007 study, economists at the California Energy Commission found that extending daylight saving time a few weeks had little effect on energy use in the state. In fact, the drop was 0.2%, within the study's margin of error.  But a 2008 study by the federal energy department found extending daylight saving time saved 0.5% in total electricity each day. It doesn't sound like much, but that's about 1.3 billion kilowatt hours, enough to power 100,000 homes for a year.

3. But most people like it and that's why everyone participates, right?

Nope. Not quite.

The United States aren't so united on this issue, with Arizona (with the exception of the Navajo Nation) and Hawaii electing to sit out the semi-annual time jump. Guam, Puerto Rico, the Virgin Islands, and American Samoa don't participate either.

The U.S. is one of more than 70 countries around the world that observe some form of daylight saving time. (As a reminder, there are just under 200 countries on Earth.)

4. Money saving or not, the time change is good for your body and mind, right?

Again, that depends.

The smart folks at Scientific American examined two daylight saving time related health phenomena.

First, the incidence of heart attacks rose about 5% during the first week of daylight, at least according to a study conducted in Sweden in the late-1980s. The same researchers published a paper in the New England Journal of Medicine in 2008 suggesting the increase may be due to sleep disruptions and biological rhythms getting out of whack.

By the same token, there are fewer automobile versus pedestrian traffic accidents since more people are driving home during sunlight.

Then again, correlation is not causation. So what do I (or those smart folks) know? Basically, the jury's out on this one.

5. Fine. But there's definitely an S on "daylight savings," right?

No, I haven't been using the wrong word this entire time. It's daylight saving time. I promise. Google it.

Somewhere along the way, we all made it plural when we started explaining it. But you know what, don't worry about trying to break the habit. Language is fluid. Time is a construct. Just roll with it.

So, you ask, why are we still trying to make this a thing?

Well, twice a year, plenty of people ask that very question. And the chorus against daylight saving time is growing stronger and stronger at the state level, where elected officials are pushing bills from coast to coast to relegate daylight saving time to the history books.

"What is the use in having this?" Texas State Representative Dan Flynn (R) told the NBC affiliate in Dallas. "And no one has a good reason."

He's not wrong.

But no matter how you feel about daylight saving versus standard time, it's here, and we all get an extra hour this weekend.

My recommendation: Use your hour to do what makes you happy. (And by the way, it's not really an extra hour, it's just the hour the government swiped from you in the spring.) Either way, make the most of it. Sleep in. Volunteer. Take a hike. Catch up on "Luke Cage."

But get going, you only have a few more minutes.

On an old episode of "The Oprah Winfrey Show" in July 1992, Oprah put her audience through a social experiment that puts racism in a new light. Despite being nearly two decades old, it's as relevant today as ever.

She split the audience members into two groups based on their eye color. Those with brown eyes were given preferential treatment by getting to cut the line and given refreshments while they waited to be seated. Those with blue eyes were made to put on a green collar and wait in a crowd for two hours.

Staff were instructed to be extra polite to brown-eyed people and to discriminate against blue-eyed people. Her guest for that day's show was diversity expert Jane Elliott, who helped set up the experiment and played along, explaining that brown-eyed people were smarter than blue-eyed people.

Watch the video to see how this experiment plays out.

Cadbury has removed the words from its Dairy Milk chocolate bars in the U.K. to draw attention to a serious issue, senior loneliness.

On September 4, Cadbury released the limited-edition candy bars in supermarkets and for every one sold, the candy giant will donate 30p (37 cents) to Age UK, an organization dedicated to improving the quality of life for the elderly.

Cadbury was prompted to help the organization after it was revealed that 225,000 elderly people in the UK often go an entire week without speaking to another person.

Young people today are facing what seems to be greater exposure to complex issues like mental health, bullying, and youth violence. As a result, teachers are required to be well-versed in far more than school curriculum to ensure students are prepared to face the world inside and outside of the classroom. Acting as more than teachers, but also mentors, counselors, and cheerleaders, they must be equipped with practical and relevant resources to help their students navigate some of the more complicated social issues – though access to such tools isn't always guaranteed.

Take Dr. Jackie Sanderlin, for example, who's worked in the education system for over 25 years, and as a teacher for seven. Entering the profession, she didn't anticipate how much influence a student's home life could affect her classroom, including "students who lived in foster homes" and "lacked parental support."

Valerie Anglemyer, a middle school teacher with more than 13 years of experience, says it can be difficult to create engaging course work that's applicable to the challenges students face. "I think that sometimes, teachers don't know where to begin. Teachers are always looking for ways to make learning in their classrooms more relevant."

So what resources do teachers turn to in an increasingly fractured world? "Joining a professional learning network that supports and challenges thinking is one of the most impactful things that a teacher can do to support their own learning," Anglemyer says.

A new program for teachers that offers this network along with other resources is the WE Teachers Program, an initiative developed by Walgreens in partnership with ME to WE and Mental Health America. WE Teachers provides tools and resources, at no cost to teachers, looking for guidance around the social issues related to poverty, youth violence, mental health, bullying, and diversity and inclusion. Through online modules and trainings as well as a digital community, these resources help them address the critical issues their students face.

Jessica Mauritzen, a high school Spanish teacher, credits a network of support for providing her with new opportunities to enrich the learning experience for her students. "This past year was a year of awakening for me and through support… I realized that I was able to teach in a way that built up our community, our school, and our students, and supported them to become young leaders," she says.

With the new WE Teachers program, teachers can learn to identify the tough issues affecting their students, secure the tools needed to address them in a supportive manner, and help students become more socially-conscious, compassionate, and engaged citizens.

It's a potentially life-saving experience for students, and in turn, "a great gift for teachers," says Dr. Sanderlin.

"I wish I had the WE Teachers program when I was a teacher because it provides the online training and resources teachers need to begin to grapple with these critical social issues that plague our students every day," she adds.

In addition to the WE Teachers curriculum, the program features a WE Teachers Award to honor educators who go above and beyond in their classrooms. At least 500 teachers will be recognized and each will receive a $500 Walgreens gift card, which is the average amount teachers spend out-of-pocket on supplies annually. Teachers can be nominated or apply themselves.

One of the major differences between women and men is that women are often judged based on their looks rather than their character or abilities.

"Men as well as women tend to establish the worth of individual women primarily by the way their body looks, research shows. We do not do this when we evaluate men," Naomi Ellemers Ph.D. wrote in Psychology Today.

Dr. Ellers believes that this tendency to judge a woman solely on her looks causes them to be seen as an object rather than a person.
