Chapter 1: What surprising benefits can come from being in a bad mood?
Today on Something You Should Know, the surprising upside of being in a bad mood. Then the idea of living in space may sound like science fiction, but it's actually closer and more complicated than you think.
Here's the thing, like if we're talking about truly living in space, like, you know, moving to another place to live, it assumes that human reproduction is possible. And we actually don't know if that's the case.
Plus, is squeezing that last little bit of toothpaste out of the tube actually worth it? And what's being done about the high cost of veterinary care? And it is high.
Veterinary costs are double U.S.
Chapter 2: Could humans actually live on another planet?
inflation. You know, it's simple supply and demand. So you don't have enough veterinarians and you have a lot more pets. So that's kind of the biggest reason for price increases. 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: What challenges do we face when living in space?
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.
Say, if you're in a bad mood, that could be good news. I'm Mike Carruthers. That's what we're going to start with today on this episode of Something You Should Know. So having a bad day may not be all bad. Research suggests that a mildly negative mood can push your brain into a more careful, detail-focused mode.
People in that state have been found to be less gullible, more skeptical, better at spotting errors, and sometimes more persuasive in written arguments than people who are in an upbeat mood. The idea is that when you feel good, you rely more on mental shortcuts. When you feel a little down, you process information more systematically.
Now, that does not mean that being miserable is better overall or that depression is somehow helpful. It just means that for certain tasks like fact-checking, editing, evaluating claims, or making careful judgments, a slightly grumpy mood may actually help. And that is something you should know. Living in space.
It may sound like science fiction or, you know, something for astronauts or the movies, but living in space is already happening.

Chapter 4: How does low gravity affect the human body?
People are living on the International Space Station right now and plans to send humans back to the moon and eventually to Mars are well underway. The real question isn't, can we get there? It's, what happens to us when we do? Because the human body was built for this planet. Gravity, sunlight, even the bacteria around us all shape who we are and how we function.
Take that away and problems emerge.
Chapter 5: What are the rising costs of veterinary care?
So what would it really mean to live in space long term? Not just survive, but actually live there. Well, that's what we're going to discuss with Scott Solomon. He's a professor at Rice University and host of the podcast Wild World with Scott Solomon. And he's author of a book called Becoming Martian, How Living in Space Will Change Our Bodies and Minds.
Hey, Scott, welcome to Something You Should Know. Well, thanks so much for having me on. So I think most people know that there are astronauts living on the space station. There are people living in space and have been for some time. But I think it's maybe more surprising to know that there are companies and people really working on the future of this, of people living in space.
So who's working on that? They include commercial space companies like SpaceX and Blue Origin, but also governmental space agencies like NASA.
Chapter 6: How is telehealth changing access to veterinary services?
I mean, the current Artemis program that is attempting to return us to the moon has the long-term goal of getting to Mars and establishing a presence there. The idea of being on the moon is basically like a way to practice and learn for how we could eventually go and live on Mars.
Once it became clear to me that this was something that was actually in the works, I became really curious and really interested to understand, what do we actually know about what would happen if those efforts are successful?
And what's driving these efforts? Is it just because it's there or because there's some reason to think we'll run out of room here? Or why would one consider living on the moon? It seems a lot nicer here.
Some see it as just a great adventure. But then there's people that see the possibility for profit, right? For mining asteroids and making money back home. But to me, the most compelling reason that I've encountered and one that really resonates with me is the idea that eventually, if we don't leave Earth, we will probably become extinct.
I mean, if you just look at the history of our planet and the history of life on Earth, you know, I'm an evolutionary biologist, so I think about life on these long timescales, and we know that there have been major catastrophes that have happened throughout the history of life on Earth. The most recent
major disaster being the asteroid impact that killed the dinosaurs and about 75% of other species at the time, which was 66 million years ago.

Chapter 7: What factors are contributing to high vet bills?
Eventually, something like that is going to happen again. We may or may not have the ability to see it coming and to take action to prevent it. So the idea there is that if we don't expand into space, if we keep all our eggs in one planetary basket, so to speak, eventually our time will come.
Well, but the future is here now in the sense that people do live in space on the space station and people go up to rocket ships. And so, I mean, people are in space and we've all heard of stories of problems people have had, health problems and whatnot. I don't know the details of that, but it isn't all future. There is some practical application to this.
Yeah, you're absolutely right. I mean, people have been living on space stations since the 1970s, and the International Space Station, the ISS, has been continuously occupied since the year 2000. So for the entire 21st century so far, somebody has been off Earth. Right. So, you know, we are at that point where we don't all live on Earth.
Now, nobody has so far lived their entire lives out in space. The record for the longest continuous time in space is 437 days.
Chapter 8: What are some common misconceptions about pet care?
So a little over a year. But, yeah, we are regularly sending people out into space and we are. uh, you know, about to send, um, people deeper into space than anybody has ever gone. The Artemis two, um, mission, which is set to launch next month is, uh, going to take a crew of four astronauts around the moon and they will actually be traveling farther from earth than any humans have ever gone.
And again, the long-term goal is to return to the moon and then to Mars. But yeah, I mean, we are at that point where people are spending longer and longer in space. They're going deeper and deeper into space. And as you said, there are some known issues that happen, right? Some known things that happen to our bodies.
And I think it's important that we understand what is going to happen to people as we spend more and more time in space.
And what are the concerns? What do we know enough about to think, well, gee, we better take a closer look at this?
Yeah, there's a whole bunch of things. So anybody that goes to space can expect a few things to happen. One is that usually people get motion sick. There's an adjustment period, kind of like when you are on a boat for a lot of folks like me. I tend to get seasick, and I would probably get space sick. People usually get over that in a couple of days at the most.
But then other things start to happen. So one of the things that happens immediately is that your body fluids start to be redistributed. So normally here on Earth, with the gravity pushing down on us, you have more fluid in your lower body than in your upper body. But that starts to change as soon as you go into a microgravity environment.
And what the body experiences then is that it feels like there's too much fluid in your head. And so astronauts, if you look at pictures of them, especially soon after they've gotten to space, their faces look kind of puffy. And their legs actually look kind of skinny. So astronauts call this space face and chicken legs. And that's just the fluids being redistributed.
But that can actually have some long-term negative consequences. So having excess fluid in the head actually puts more pressure on the eye. And astronauts that have spent a long amount of time in space, like a year, they have often had vision deterioration. And so that is thought to be linked to those fluid shifts. So that's something that's a bit concerning.
We don't know what would happen if they're there for even longer, because again, the record is just a little over a year. Also, long duration space flight comes with muscle atrophy. again, not having to work against gravity. We don't think about gravity pushing down on us and us fighting against it when we're on Earth. But but we are.
