Something You Should Know
The Untold Story of the Christmas Tree & The New Rules of Eating Out
08 Dec 2025
Chapter 1: Why is yawning contagious?
Today on Something You Should Know, yawning is contagious, but do we really know why? Then the fascinating story of Christmas trees, and are they any different than normal evergreen trees?
Fascinating thing is that Christmas trees are the same species that if you just let them grow, they'll be 100 feet tall and can be called lumber. They're just raised differently. So the cultural practices on Christmas tree farms are fine tuning those trees to make them look good for Christmas.
Also, did you know eating some foods can actually make you hungrier? And the new reality of dining out, why it's so expensive, and what you don't see behind the scenes.
Chapter 2: What is the history behind the Christmas tree tradition?
Nothing that you ask for in a restaurant is ever easy. The natural state of a restaurant is chaos, and all of the people that are working behind the scenes, their job is to try to guard you as the guest from the chaos behind the scenes.
All this today on Something You Should Know.
Ah, the Regency era. You might know it as the time when Bridgerton takes place, or as the time when Jane Austen wrote her books. The Regency era was also an explosive time of social change, sex scandals, and maybe the worst king in British history. Vulgar History's new season is all about the Regency era, the balls, the gowns, and all the scandal.

Chapter 3: How do Christmas trees differ from regular evergreens?
Something you should know. Fascinating intel. The world's top experts. And practical advice you can use in your life. Today, Something You Should Know with Mike Carruthers.
I think we've all experienced the fact that yawning can be contagious. But why? That's what we're going to start with today. Hi, I'm Mike Carruthers. Welcome to Something You Should Know. So the reflex to yawn has its roots in physiology, tiredness, boredom, maybe even brain temperature. But the contagious part of yawning, that's a real mystery.
Research shows that seeing, hearing, or even thinking about someone yawning can trigger a yawn in you. Why does that happen? Well, there are two leading theories. One is automatic mimicry. Our brains automatically imitate actions we observe, thanks to mirror neuron systems. When we see someone yawn, the same neural circuits fire as if we were yawning. The other theory is about how groups behave.
In social species, including humans, contagious yawning may have evolved to help synchronize the group's state. It's not fully explained yet.
Chapter 4: What are the challenges facing the restaurant industry today?
For example, that popular, we yawn to bring oxygen to our brain, and so we trigger each other. Well, that idea has largely been discounted. And while it may relate to empathy, because we do catch yawns from people we're close to more often, the link between yawning and empathy is inconsistent across studies. So why we yawn when other people yawn, it just isn't really well understood.
And that is something you should know. For many people who celebrate Christmas, the season doesn't officially begin until the pine tree goes up in the living room. It's the centerpiece of the tradition. So familiar, we barely question it. But the pine tree isn't just a holiday symbol. It's a survivor, a resource, and a driving force in American and human history.
Chapter 5: How has dining out changed post-pandemic?
Its journey from wild forests to living rooms is far more remarkable than most people realize. And here to walk us through that story is Trent Pressler. He's a professor at Cornell University's Applied Economics and Management program and author of the book Evergreen, The Trees That Shaped America. Hi, Trent. Welcome to Something You Should Know. Happy holidays. Hi, Mike. Thanks for having me.
Sure. So explain what an evergreen tree is. I mean, you can look at it and see it's different than other trees. It has needles and not leaves, and the needles stay on in the winter. But from your perspective, what is an evergreen tree?
It's so many things. First of all, the main difference, which is rooted in the name, obviously, is that they don't lose their foliage in the winter.
Chapter 6: Why do some foods leave you feeling hungrier?
So they're extremely winter hardy, and they've evolved this kind of strange conical shape, which is different from all other trees. And in part, that's because they grow in the northern climates where there's a lot of snow, and that kind of helps deflect snowfall. Another fascinating thing about their shape, the identifiable Christmas tree shape of an evergreen,
is also related to capturing as much light as possible. They grow so far north that there's often, in the wintertime, you know how the sun kind of shines low in the sky? So you get a lot of side light instead of overhead light. So by having that pyramidal shape, they're able to absorb a lot of light from the sides in addition to overhead. But they are tough as nails.
These trees grow in the most inhospitable climates. I compare them to the botanical equivalent of city pigeons. They can survive on a rock ledge clinging to life with almost nothing. And they're also prehistoric. They are some of the first plants that appeared in the fossil record hundreds of millions of years ago.
And so one day somebody said, let's bring a Christmas, let's bring an evergreen tree into the house because it's Christmas. And I never really understood like, well, what was that about? But how did that come about? Do we know or did it just kind of happen and now we do it because everybody does it?
We have a vague idea. So there were pagan rituals associated with the winter solstice in ancient history and people would bring in evergreen boughs and evergreen trees from outside as kind of a talisman against winter's darkness. And on the winter solstice, the shortest day of the year, the evergreen boughs represented hope for the future and sort of a light and life in the darkness.
And then the first known recorded instance of, I guess, a modern era Christmas tree, there were a couple of reports in the 1500s in Germany, in small villages in Germany where villagers erected trees and decorated them with bread and ginger and apples and candies and then it spread throughout Germany first.
Then from there, it really spread throughout Europe and eventually made its way to the United States in the early 1800s, the tradition of bringing in a tree for the winter.
Wasn't the British royal family somehow involved in the story of popularizing the Christmas tree?
Probably the most popularized form of a decorated tree happened in England with some members of the royal family who put up a tree and decorated it. Then there was a very popular magazine in America in the 1800s called Godey's Lady Book. And they published this photo of English royalty posing with a decorated tree. And it kind of spread. I guess it was one of the original viral images.

So Trent, the trees that we take into our home and decorate, for the most part, they are grown for that purpose. And how is that different than growing pine trees for lumber or furniture?
The fascinating thing is that Christmas trees are the same species that if you just let them grow, they'll be 100 feet tall and can become lumber. But they're just raised differently. So the cultural practices on Christmas tree farms are fine-tuning those trees to make them look good for Christmas.
So that involves quite a few steps, hundreds of steps, in fact, from the moment you plant that tree as a seedling to the moment maybe eight to 10 years later when it gets cut down for a Christmas tree. They prune them, they shape them a couple times a summer, and by cutting off and shearing the branches, the tree responds by producing even more branches, so an even fuller structure.
Nobody likes a gangly-looking, empty, sparse Christmas tree. Everyone likes a full tree. It involves all kinds of tricks of the trade, not just shearing, but also Christmas tree farmers will use almost like a cigar cutter to kind of splice the top leading spire of a Christmas tree, which makes the tree think that, well, maybe I shouldn't be growing taller.
And they invest more energy in their lower branches and then becoming more, you know, a thicker, more beautiful tree.
So if I go into the Christmas tree farming business, I have to wait eight to ten years before I make a dime?

Chapter 8: How can understanding restaurant dynamics improve customer experiences?
After 10 years, maybe you get sick of it, it's got dust, the branches are bent. It's kind of not true that artificial trees are forever. They're not. Just like, you know, something like IKEA furniture, there's some research that shows that the average lifespan of IKEA furniture is about seven years. The average lifespan of an artificial Christmas tree is about 10 years.
Well, I certainly understand why you might want an artificial tree, but boy, there is something about a real Christmas tree.
Nothing can replace a real tree. The smell, the texture, and the imperfections of it, the things that kind of remind us of our childhood still hold so much power. And a lot of baby boomers actually switched to artificial trees after their kids left the house. And they did so for a couple reasons.
The first was convenience, because, well, now I don't have the mess of the needles, and it's just a lot easier, and I don't have to go through the hassle.
um and the second was i think for many people they felt like well i'm no longer tied to those childhood traditions because my children are no longer at home and then i've heard as i traveled the country you're not the only person i have heard this from that you switch to the artificial and then you miss the real
I have heard that so many times from people that they do it for the reasons I just described, but then it kind of makes them miss the magic of a real tree.
Yeah, I miss the every year my brother and I would get in the car with our father and we would go look at trees.
christmas tree lots and you know it was a whole tradition and now it's now you just go to the closet and get the box out and it just doesn't it doesn't have the it doesn't have the memory that that that did so yeah i can understand that but on the other hand you know i remembered a time when fake christmas trees looked really fake but some of them now look so real that i
I understand the appeal more now than before. But as you say, the ones that look really good are pretty expensive. So you're going to have to keep it for years before you get your money's worth.
