Ever wonder what the science behind heartbreak is? Find the answer here.

Find out what happens to your body when you see someone you love (and more!)

Love doesn't have to be all about romance. It can also be about SCIENCE.

And who doesn't love some science? Let's take a look at some of the hard facts of the history and science of the heart.


Hahhhh. Get it? Limbic system = part of the brain.


FACT: By 2000 B.C., Chinese doctors had uncovered the heart's role in pumping blood throughout the body.


This diagram of the heart is from a medical book published in 1864.

Yep, they figured that ish out in 2000 B.C., as in 4,000 years before today. Also known as a ridiculously long time ago. Meanwhile (or rather, about 1,600 years later), Aristotle was busy hypothesizing that the heart was the center of intelligence. Even through the Renaissance, many great thinkers believed that the heart governed a person's emotions — "a notion so powerful that it still persists today in a different form."

FACT: Even though feelings of love come from our brain, we really can physically feel them.

Pretty cool, huh? Let's take a look at both sides of this coin.

The "happy side" of feeling love is that when you see a loved one, your brain stimulates the release of neurotransmitters that make you feel real good. Epinephrine and norepinephrine are secreted from your adrenal glands, which cause your heart to beat faster.


Yay!

Of course, those aren't the only neurotransmitters involved in love. There are SO many chemicals and hormones at play — dopamine, serotonin, oxytocin, vasopressin ... on and on. They all work together to govern sex drive, partner preference, and attachment. It's complicated science, but the bottom line is simple: When you're in love, your body reacts big time. It's far from "all in your head."


Slightly cute, mostly creepy. For more info on other chemicals involved in love, check out this video.

The "heartbroken side" of feeling love is that emotional loss activates the same region of your brain as physical pain. This can lead to great levels of neurological stress, which can actually overstimulate your vagus nerve, causing nausea, dizziness, and physical pain. That's heartbreak.


And that's why you can actually feel a broken heart.

FACT: Many animals average 1 billion heartbeats in their lifetime, no matter their size or life span.

The billion beat hypothesis says that an animal's heart will beat around 1 billion times, no matter their size or life span. Smaller animals have shorter life spans and faster heart rates whereas larger animals have longer life spans and slower heart rates.


That's heart beats per minute, life span in years, and lifetime heartbeats in billions.

Small animals have a larger ratio of surface area to mass, so they lose heat more quickly and have higher metabolic rates — which are linked to shorter life spans. As mass goes up, so do life spans while heart rates go down.


Is this all just a complicated way of saying that mice don't live very long? Maybe so.

But HUMANS defy the billion beat hypothesis. We live three times as long as we should with about twice as many heartbeats as we should be "allotted." Why? Because modern science and medicine have extended our life span. It's pretty corny, but ...

Caring for one another helps humans defy the principles of science.

Glenda moved to Houston from Ohio just before the pandemic hit. She didn't know that COVID-19-related delays would make it difficult to get her Texas driver's license and apply for unemployment benefits. She quickly found herself in an impossible situation — stranded in a strange place without money for food, gas, or a job to provide what she needed.

Alone, hungry, and scared, Glenda dialed 2-1-1 for help. The person on the other end of the line directed her to the Houston-based nonprofit Bread of Life, founded by St. John's United Methodist pastors Rudy and Juanita Rasmus.

For nearly 30 years, Bread of Life has been at the forefront of HIV/AIDS prevention, eliminating food insecurity, providing permanent housing to formerly homeless individuals and disaster relief.

Glenda sat in her car for 20 minutes outside of the building, trying to muster up the courage to get out and ask for help. She'd never been in this situation before, and she was terrified.

When she finally got out, she encountered Eva Thibaudeau, who happened to be walking down the street at the exact same time. Thibaudeau is the CEO of Temenos CDC, a nonprofit multi-unit housing development also founded by the Rasmuses, with a mission to serve Midtown Houston's homeless population.

Eight months into the pandemic, you'd think people would have the basics figured out. Sure, there was some confusion in the beginning as to whether or not masks were going to help, but that was months ago (which might as well be years in pandemic time). Plenty of studies have shown that face masks are an effective way to limit the spread of the virus and public health officials say universal masking is one of the keys to being able to safely resume some normal activities.

Normal activities include things like getting a coffee at Starbucks, but a viral video of a barista's encounter with an anti-masker shows why the U.S. will likely be living in the worst of both worlds—massive spread and economic woe—for the foreseeable future.

Alex Beckom works at a Starbucks in Santee, California and shared a video taken after a woman pulled down her "Trump 2020" mask to ask the 19-year-old barista a question, pulled it back up when the barista asked her to, then pulled it down again.

Pete Buttigieg is having a moment. The former mayor of South Bend, Indiana keeps trending on social media for his incredibly eloquent explanations of issues—so much so that L.A. Times columnist Mary McNamara has dubbed him "Slayer Pete," who excels in "the five-minute, remote-feed evisceration." From his old-but-newly-viral explanation of late-term abortion to his calm calling out of Mike Pence's hypocrisy, Buttigieg is making a name for himself as Biden's "secret weapon" and "rhetorical assassin."

And now he's done it again, this time taking on the 'originalist' view of the Constitution.

Constitutional originalists contend that the original meaning of the words the drafters of the Constitution used and their intention at the time they wrote it are what should guide interpretation of the law. On the flip side are people who see the Constitution as a living document, meant to adapt to the times. These are certainly not the only two interpretive options and there is much debate to be had as to the merits of various approaches, but since SCOTUS nominee Amy Coney Barrett is an originalist, that view is currently part of the public discourse.

Buttigieg explained the problem with originalism in a segment on MSNBC, speaking from what McNamara jokingly called his "irritatingly immaculate kitchen." And in his usual fashion, he totally nails it. After explaining that he sees "a pathway to judicial activism cloaked in judicial humility" in Coney Barrett's descriptions of herself, he followed up with:

When you picture a ballerina, you may not picture someone who looks like Lizzy Howell. But that doesn't mean you shouldn't.

Howell is busting stereotypes and challenging people's ideas of what a dancer should look like just by being herself and doing her thing in her own body. The now-19-year-old from Delaware has been dancing since she was five and has performed in venues around the world, including Eurovision 2019. She has won scholarships and trains up to four hours a day to perfect her skills in various styles of dance.

Jordan Matter Photography shared a documentary video about Howell on Facebook—part of his "Unstoppable" series—that has inspired thousands. In it, we get to see Howell's impressive moves and clear love of the art form. Howell shares parts of her life story, including the loss of her mother in a car accident when she was little and how she was raised by a supportive aunt who helped her pursue her dance ambitions. She also explained how she's had to deal with hate comments and bullying from people who judge her based on her appearance.

"I don't think it's right for people to judge off of one thing," Howell says in the video. And she's right—her size is just one thing.
