Starting point is 00:00:00 On the podcast, Hey Dude, the 90s called, David Lasher and Christine Taylor, stars of the cult classic show, Hey Dude, bring you back to the days of slip dresses and choker necklaces. We're gonna use Hey Dude as our jumping off point, but we are going to unpack and dive back into the decade of the 90s.
Starting point is 00:00:17 We lived it, and now we're calling on all of our friends to come back and relive it. Listen to Hey Dude, the 90s called on the iHeart radio app, Apple Podcasts, or wherever you get your podcasts. Hey, I'm Lance Bass, host of the new iHeart podcast, Frosted Tips with Lance Bass. Do you ever think to yourself, what advice would Lance Bass
Starting point is 00:00:37 and my favorite boy bands give me in this situation? If you do, you've come to the right place because I'm here to help. And a different hot, sexy teen crush boy bander each week to guide you through life. Tell everybody, ya everybody, about my new podcast and make sure to listen so we'll never, ever have to say. Bye, bye, bye.
Starting point is 00:00:57 Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple Podcasts, or wherever you listen to podcasts. Hi everybody, it's Chuck, and I am introducing this week's Stuff You Should Know Selects episode. This is from the vault from 2009, November 12th, and it's called How Population Works. And I picked this one because I remember this being
Starting point is 00:01:23 a super cool episode because it was one of those where I thought, population, what does that even mean? And how can we make a show out, a full show about this? And it turned out to be great. Josh, I think it was his pick initially, and it's just really, really cool. So if you don't even know what how Population Works might mean, give it a listen.
Starting point is 00:01:44 I think you'll be pretty intrigued. Welcome to Stuff You Should Know from HowStuffWorks.com. ["Punkin' Chunkin'"] Pumpkin' Chunkin', Pumpkin' Chunkin', Pumpkin' Chunkin'! That's right, Chuck Hay, and welcome to the podcast. I'm Josh Clark, clearly Chuck Bryant's here, and let's talk about Pumpkin' Chunkin', I guess.
Starting point is 00:02:12 You just kind of forced our hand, Chuck. Yes, the road to Pumpkin' Chunkin' and Pumpkin' Chunkin'. So that's on Science Channel, 8 p.m., Eastern Time on Thanksgiving night. Yeah. And Pumpkins get chunked. Pumpkins get chunked. Pumpkins, yeah, okay.
Starting point is 00:02:27 Again, Science Channel, the road to Pumpkin' Chunkin' starts at 8 p.m., Eastern Time. Pumpkin' Chunkin' itself starts at 9. Great. Thanksgiving night. Yes. Science Channel. On with the show.
Starting point is 00:02:38 Yeah, Chuck, have you ever belonged to a population? No, man, I'm like, I'm totally independent. Screw populations. You're like that guy who lives in the commune, right? Right. Yeah, well, the joke's on him because a commune constitutes a population. That's right.
Starting point is 00:02:55 This sounds kind of boring, and you would think it is. I thought it might be. Wonder if I could do how a population works. It actually started to pick up. I actually didn't know what it was even gonna be when I saw how a population works. I was like, what? You know what's awesome?
Starting point is 00:03:06 This was my idea, this article was. I pitched it. Oh, really? Mm-hmm. Why didn't they let you write it? I don't know. Chirks. I know, but the Grabster did a good job with it.
Starting point is 00:03:14 Oh, yeah, the Grabster's always good. Yeah, classic. That's Ed Grabinowski, by the way. Right, so human beings, marriage, human beings tend to congregate. Yes, and segregate, interestingly. That is an excellent, you just blew my mind. Good Lord, Chuck.
Starting point is 00:03:36 Well, let's get back to what I was saying. Right. Unless you wanna go on the segregation, right? We'll get on that later. Humans congregate and segregate, but let's talk about congregation in that. Most of the time, I would say, are early, early ancestors, and probably even other species congregate
Starting point is 00:03:55 because there's safety in numbers. Sure, and it helps, like with farming, collecting water and food, power numbers. But even before farming, hunter-gatherers lived in bands. I think 30 was about tops. They figured out somewhere along the way that groups of 30, or groups of more than 30, there tended to be a lot more hostility
Starting point is 00:04:14 and intergroup problems. Have you ever tried to kill a mastodon by yourself? That's another good point, too. There's cooperation, mastodon. Let's say if you are farming and your crop fails, well, you're not standing there like, well, I'm in trouble. Yeah, I'm gonna die then.
Starting point is 00:04:34 You can say, hey, neighbor, I'll totally give you favors of some variety if you will let me have some of your grain. Right, I'll give you a chicken, let's say. Sure, you can trade. Yeah, barter. A lot of reasons people live together. So it's my theory that people aggregate together naturally.
Starting point is 00:04:53 Yes. And then there are people out there who get their jollies by studying these groups of people. They're called demographers. Yeah, demographers. So we have populations, natural or otherwise, and let's say a natural population today are people who live in a certain state.
Starting point is 00:05:09 Yeah, Georgians. Right, that's where we are. So you have natural populations in demographers' study, right? Sure. And they look at things like, say, how many people in this natural population are Republicans? Or Democrat, or how many are Caucasian.
Starting point is 00:05:26 Right. Or how many have, how many are live below the poverty line? All kinds of things you can study. Right. By looking at a population. And are these groups segregated? Like you brought up.
Starting point is 00:05:40 You know, like if you study where different races are living, are they living mingling, if so, then that's probably a fairly harmonious place, hopefully. Right. If not, why are they living apart? How do we fix this? Because it's probably a problem. Sure.
Starting point is 00:05:55 Who knows? But yes, so demographers study populations natural or otherwise, right? Yes. The problem is, is you very few people have the ability to hover over the earth and use super binocular vision to study populations by sight. Yeah, very few people.
Starting point is 00:06:14 Yeah. Like three or four, I think. Perhaps. So. Does that count as a statistic? I think so. Okay. Richard.
Starting point is 00:06:22 So measuring populations, is that what you're gonna talk about? How do we actually determine this kind of thing? Yeah. That was my segue. That was a good segue. There's a couple of ways, Josh. One is by counting them, literally counting them. Like a census.
Starting point is 00:06:36 Counting every single person. Right. And that is called complete enumeration. Yeah. Remember we talked about that poor guy who was killed or possibly killed himself in Kentucky? The census taker? Right.
Starting point is 00:06:46 Oh, I didn't know that suicide was a possibility there. I got a cryptic email from somebody I never followed up on that said that he identified himself as a doctor. And I think said that he was a part of the group that was the medical examination team and said that they strongly suspected suicide. Really? My problem with it is, is how do you bind yourself in duct tape?
Starting point is 00:07:09 I don't know. How do you bind your own wrists in duct tape? I'll show you later. Okay. So my point is, wow, he threw me off with that one. My point is that he was called an enumerator. Yes. Literally counter.
Starting point is 00:07:25 And that's the people who work for the census whenever they have their drive and they count. Right. And that's one way to determine it. Well, let's talk about the census. It's gone on every 10 years since 1790, right? Yeah. And the reason they do it every 10 years
Starting point is 00:07:38 is because it's a real pain in the ass to count every person in America. Yeah, the real reason they do it is so they can, well, there's a lot of reasons, but taxes, taxes, taxes. That is the reason why anyone's ever conducted a census. Yeah, well, plus they determined the number of house representatives for your state based on population, stuff like that.
Starting point is 00:07:56 Oh yeah, there's that too. But you know, come on, taxes. Did you know that the census information is kept secret for 72 years? Yeah, aside from the numbers, I believe. Right. The public cannot see that information for 72 years. Right.
Starting point is 00:08:12 That's odd. It is odd. I wonder if that was the average lifespan at the time or something. Dude, that's gotta be it. I'll bet you're right. Okay, the other way, Josh, is to do something called sampling.
Starting point is 00:08:27 And that is when statisticians use a mathematical formula to determine the minimum number of people that must be counted, and then they multiply that out and basically end up getting a full population. And sometimes, I didn't know this, that's even more accurate than an actual head count. Right. You see that margin of error?
Starting point is 00:08:48 It's like plus or minus 4%? Yeah, you gotta have a margin of error there whenever you're sampling. Right, because you're not actually going around asking every single person in America, are you left-handed to determine how many people are left-handed. Yeah.
Starting point is 00:09:01 But let's say you have a population of 1,000 and some statistician's been like, you need 100 and do it. What? Do your egghead voice. Ew. Yeah, you need 150 people. The 150 people that are left-handed,
Starting point is 00:09:16 and you can just multiply that out to determine that there are, in fact, how many people? Let's say 10% of the population. 10% of the population. Right, but your sample is perfect, Josh. Your sample has to be a random sample to be an effective sample. Yeah, and you know how they used to do that?
Starting point is 00:09:34 Uh-huh. They used to just pick it out of the phone book. Oh, I know. And call people. I know, and that makes sense to a certain extent? No, it doesn't. Well, back then, it made a little more sense. I would think it made less sense,
Starting point is 00:09:46 especially if you're talking like 1950 or so. Well, it depends on what year. I'd say in the 1980s, it was probably a good way, but now there's cell phones, people in college probably don't have a phone. Poor people who don't have phones at all. Poor people who don't have phones, sure. So that's not a very good way, because.
Starting point is 00:10:01 What about freight train riders of America? What's that? They don't have phones. Oh yeah, good point. Yeah. I don't think they want them. So sampling is a little harder than it seems. Yeah.
Starting point is 00:10:13 Right, especially coming with a random population, random sample of the population. But, okay, so, so far we've talked about people and where they live. Right. There's other ways to define a population. There's other attributes that people have that we use to lump into population.
Starting point is 00:10:29 Yeah, it's not just a geography. When people think populations, it's not just a city population. Or state. Yes. Or nation. Age, you can have a population of age. Or continent.
Starting point is 00:10:41 A demographic. Right. What else? Location, of course. Socioeconomic population. Well, let's talk about age. Why would you even want to know age? Who cares?
Starting point is 00:10:50 People are old, people are young, whatever. Right, well, there's a lot of factors. Like, take the baby boom, for instance. After World War II, all these babies were born. So there was a bulge in the population. And I just like saying the word bulge. But you got to do the air quotes. Air quotes, yeah.
Starting point is 00:11:04 So what that will show them then is, wow, we got a bulge here. So that means probably in 25 to 60 years, there's going to be some serious buying power in this country. Right, let's start borrowing as much money as we can right now. Right, but it also means in 70 plus years,
Starting point is 00:11:21 that they may be a medical burden and a burden on social security. Right. I'm not going to think. So let's start borrowing as much money as we can right now. Right. Yeah.
Starting point is 00:11:30 Same result there. I like that. We'll get to bulges again in a little bit. Yes. But let's move on. Like you said, socioeconomic data, right? Yeah, why would they want to do this, Josh? This one, I find this the most interesting of all data.
Starting point is 00:11:44 Okay. You can look at a bunch of people who are maybe related geographically. Right. But other than that, aren't related in any other way. Sure. And all of them suddenly have this horrible cancer. And there just so happens to be
Starting point is 00:12:00 some paint manufacturer nearby. What did you say? High tension wires. Sure. Which has been proven, I think, to not actually have any effect on people. Not in my buddy. So now all of a sudden you have this information.
Starting point is 00:12:16 Thanks to your demographer friend who went and collected it. And you can say, okay, paint factory, you guys better start giving away some free paint. Yeah. Or we're going to sue you. Yeah, true. Right. Race.
Starting point is 00:12:30 That's a little more hinky. Because technically there is no such thing as any difference in different races. I remember watching MTV years and years and years ago. And the VJ was interviewing the BC boys. And he was like, Mike D, I hear you're dating a black girl. You know, what's it like dating somebody from a different race?
Starting point is 00:12:50 Which is just an asinine question to begin with. But I remember Mike D going, there's only one race, the human race. And I was like, huh, Mike D's right. Wise words, Mike D. That was clearly before he was down with the Ioni. Or no, that was Adrock. Sorry.
Starting point is 00:13:05 Yeah, Adrock's down with the Ioni. Yeah, they're divorced though. So he's not down with her anymore. Poor Ioni. So yeah, race is a little hinky. But you can't actually determine some useful things when you study populations of race. Because of like, you know, it's important for people
Starting point is 00:13:20 to be involved in their culture. Yeah. And to hang on to that, for sure. I guess racial profiling, again, I don't know if I should say again or not. But it's such a hot button issue that, yeah, I don't know. We need to talk about it collectively. That's my answer for everything.
Starting point is 00:13:37 Everybody needs to get together and decide what we want to do, OK? Well, the other thing with race though is if there's a medical problem that's specific to that race that can help out. That, exactly. Sure. On the podcast, HeyDude, the 90s, called David Lasher
Starting point is 00:14:00 and Christine Taylor, stars of the cult classic show, HeyDude, bring you back to the days of slip dresses and choker necklaces. We're going to use HeyDude as our jumping off point. But we are going to unpack and dive back into the decade of the 90s. We lived it. And now we're calling on all of our friends
Starting point is 00:14:17 to come back and relive it. It's a podcast packed with interviews, co-stars, friends, and nonstop references to the best decade ever. Do you remember going to Blockbuster? Do you remember Nintendo 64? Do you remember getting frosted tips? Was that a cereal? No, it was hair.
Starting point is 00:14:33 Do you remember AOL instant messenger and the dial-up sound like poltergeist? So leave a code on your best friend's beeper because you'll want to be there when the nostalgia starts flowing. Each episode will rival the feeling of taking out the cartridge from your Game Boy, blowing on it, and popping it back in as we take you back
Starting point is 00:14:48 to the 90s. Listen to HeyDude, the 90s, called on the iHeart radio app, Apple Podcasts, or wherever you get your podcasts. Hey, I'm Lance Bass, host of the new iHeart podcast, Frosted Tips with Lance Bass. The hardest thing can be knowing who to turn to when questions arise or times get tough, or you're at the end of the road.
Starting point is 00:15:08 OK, I see what you're doing. Do you ever think to yourself, what advice would Lance Bass and my favorite boy bands give me in this situation? If you do, you've come to the right place because I'm here to help. This, I promise you. Oh, god. Seriously, I swear.
Starting point is 00:15:21 And you won't have to send an SOS because I'll be there for you. Oh, man. And so will my husband, Michael. Um, hey, that's me. Yeah, we know that, Michael, and a different hot, sexy teen crush boy band are each week to guide you through life, step by step.
Starting point is 00:15:36 Oh, not another one. Kids, relationships, life in general can get messy. You may be thinking, this is the story of my life. Just stop now. If so, tell everybody, yeah, everybody about my new podcast and make sure to listen so we'll never, ever have to say bye, bye, bye. Listen to Frosted Tips with Lance Bass on the iHeart
Starting point is 00:15:56 radio app, Apple Podcast, or wherever you listen to podcasts. Learning stuff with Joshua and Charles, stuff you should know. All right, so Chuck, we've got all these different factors. Yes. Attributes, variables. We've used the word demographer several times. So we know that people study populations. One of the reasons why we study populations
Starting point is 00:16:26 is to see how big it's getting. Yeah. And I got to tell you, buddy, the human population has kind of exploded on this planet in the last several thousand years. Yeah, but you know what? They're reading these stats. There were a lot more people here way back when
Starting point is 00:16:42 than I thought. Yeah, again, favorite book of all time, 1491. Charles C. Mann, he basically points out that there is probably 100 million people in the Americas in 1491. That's awesome. Yeah, which is a fifth of the world population is way more than anyone thought.
Starting point is 00:17:04 Yeah. And the reason why is because 1492, Columbus shows up. Smallpox just ravages both continents. And by the time the European settlers start coming for real, the place is decimated. It seems like there's nobody there. Right, well, he had the whole genocide too thing. Did you ever know about that, Columbus?
Starting point is 00:17:22 I hear his men used to sharpen their knives on the skulls of live natives. Well, there's the, because genocide we talk about later on in the article, but there's speculation that Columbus may have been responsible for the worst mass genocide in human history. Wow. By completely wiping out the Taino, Taino Indian people.
Starting point is 00:17:48 Really? And that was in Hispaniola, which is modern day, I think, Haiti and Dominican Republic. And some people say there were only like 500,000 of them. And some people say there were as many as 15 million at the time that were decimated to about 2,000. Decimated through violence or through disease? Yeah, well, through violence, because Columbus came over,
Starting point is 00:18:07 set up a camp in Hispaniola for about 40 people, and then left, came back on trip number two, and found that the Indian tribe there had killed all those people. So he went on a kill crazy rampage, basically, and completely wiped out the population. And they're saying it may have been double the size of the Holocaust.
Starting point is 00:18:26 Wow. So happy Columbus Day, everybody. Yes, seriously. But we do mention that, because genocide is a way that a population can change rapidly. Well, let's talk about population growth. Yes. All right, so I guess about 10,000 BC,
Starting point is 00:18:40 they estimate that there is between 1 and 10 million humans. So we're starting to slowly grow, because by 1,000 BC, there's 50 million. Yeah. And then by 600 CE, we're at 200 million. See, that's a lot more than I thought there would be at the time. Yeah.
Starting point is 00:18:57 I think there was about 500 million in the mid-15th century. Crazy. So let's go by, let's say there's 500 million in the mid-15th century. The 20th century, the Industrial Revolutions happened. Yeah. There's been great leaps in science and medicine. That's when populations really grow,
Starting point is 00:19:17 is during those big booms. Yeah, because it lends itself to fertility, higher fertility, and longer lifespans. Yeah. Good times, breed kids. So the 20th century hits were at 1.5 billion people. Indeed. And then this century, the population of the world
Starting point is 00:19:34 has quadrupled. Yeah. So it was like 6 billion. I know that it sounded like there should have been a drum roll there, but I'm impressed by that. Jerry might have put one in there, or producer Jerry. We'll find out later. And Josh here projecting, the US Census Bureau projects
Starting point is 00:19:50 that by the year 2050, there will be 10 billion people. Right. So the reason for this is what we call the Malthusian growth model. Yes. Malthus was a 18th century clergyman. Yeah, Thomas. He actually, I guess, inadvertently became
Starting point is 00:20:08 one of the great economic theorists. And he figured out that population grows exponentially. Right. So if you have 1 million people and they have enough kids to double the population, for the next generation, you have 4 million people. So in one full generation, you've gone from 1 million to 4 million people.
Starting point is 00:20:25 Right. Right? Yeah. That's big. It is. Especially when the planet is finite in size. Right. And we don't have the ability to go colonize other planets yet.
Starting point is 00:20:35 Right. But it's not necessarily that incremental and steady because of what we talked about, which are bulges or spikes and bottlenecks, like genocide. Right, yeah. So it doesn't always grow steadily. And actually, Chuck, have you heard of the replacement rate? No.
Starting point is 00:20:54 The replacement rate is how many kids a woman has to have to have a high statistical probability of having a daughter so that she, in essence, replaces herself. Gotcha. And right now, it's 2.33. Is the replacement rate worldwide? And the point of it is to trend toward zero population growth. Right.
Starting point is 00:21:17 So for every woman who dies, she has a daughter that can reproduce and continue on and continue on and continue on. So you have, overall, as many people dying as are being born. So there's no strain. Right, right. And there's also no dearth of people. Well, it's equilibrium.
Starting point is 00:21:35 Readen, this reminded me of when we did our big econ audio book. It's kind of, population kind of wants to seek equilibrium, I think, like just like economics does. And it doesn't always happen organically. I should say it probably rarely happens organically. But let's think about, like you said, the baby boom. The post-war success in Europe and the US and Canada, I guess, led to a huge boom in the population.
Starting point is 00:22:06 Nobody went to war to grow the population. It was just an indirect effect. So all of a sudden, we had a population spike that created a bulge. A bulge, if you will. Things can go the other way, too, which is the bottleneck, right? Yeah, and that's, well, we, and God, if I say genocide one more time, we should do a podcast on genocide. I wonder if there's a drinking game where every time you say genocide,
Starting point is 00:22:27 that's crazy. Genocide, drink. Famine, disease, something called the plague, I think, wiped out like half the world population at one point, or half the population of Europe. They suspect that in the fifth century, that would be CE, the plague of Justinian may have killed as many as half the world's population, 100 million people.
Starting point is 00:22:51 Unbelievable. Can you imagine walking around at that time like, holy crap, the entire half the world is dead. Just died in the last couple of years. It's crazy. Well, and the Black Death killed 20 to 30 million Europeans. So plagues can happen. There's also, I was talking to an evolutionary geneticist,
Starting point is 00:23:09 this is my way. Sure, at much today. Recently, and he was talking about a study he authored where they found two evolutionary bottlenecks, one coming out of Africa. They suggested it 50,000 years ago, and another one that happened along the Bering Land Bridge. Right. And he wasn't saying like all of a sudden a bunch of people died,
Starting point is 00:23:33 but these bottlenecks turned up because big groups of people separated in smaller groups of people, which accounts for a loss of genetic diversity. Gotcha. So you have the founder's effect, because as he put it, if you go into a town and grab the first 15 people you meet, and say, let's go find a new town, that new town isn't going to have a representative sample of all
Starting point is 00:23:55 the surnames in that town. Sure. If you do that enough time, some surnames are going to be lost because people didn't reproduce or whatever. Same thing happens with genes and genetic diversity. Well, look at you. Good stuff. Thanks.
Starting point is 00:24:08 Can I mention this place in Hong Kong? Yeah. We're talking about, well, we should mention population density is the number of humans per unit area, whatever unit you choose to call it. And the highest ever is believed to have been a place called Kowloon Wald City in Hong Kong. And at one point, evidently, there were 50,000 people
Starting point is 00:24:33 in a megablock, which is 500 by 650 feet. 50,000 people stuffed in there. And apparently it was a lawless district, the Grabster says. Of course. You kidding me? 50,000 people could conceivably get along. Yeah, hands across America style. Did you know that in Athens when widespread panic
Starting point is 00:24:51 played that free show, there was an estimated 100,000 people there, not one fight? Really? Yeah. That's because they were all on dope, the dope. I wasn't there. Were you there? Yeah, I never got into them.
Starting point is 00:25:04 Although I did hang out with that guy, the bass player. Day schools? Yeah, I hung out with him a couple of times, just through friends. Sure. Anyway, that park is now a park where the Wald City used to be. Yeah, which is the opposite of the highest population density. Exactly.
Starting point is 00:25:21 Yeah, ironically, it's just a park. Maybe the highest population of grass, but that's it. Yeah. On the podcast, HeyDude, the 90's called David Lasher and Christeen Taylor. Stars of the cult classic show HeyDude bring you back to the days of slip dresses and choker necklaces. We're going to use HeyDude as our jumping off point,
Starting point is 00:25:52 but we are going to unpack and dive back into the decade of the 90s. We lived it, and now we're calling on all of our friends to come back and relive it. It's a podcast packed with interviews, co-stars, friends, and non-stop references to the best decade ever. Do you remember going to Blockbuster? Do you remember Nintendo 64? Do you remember getting Frosted Tips? Was that a cereal?
Starting point is 00:26:14 No, it was hair. Do you remember AOL Instant Messenger and the dial-up sound like poltergeist? So leave a code on your best friend's beeper, because you'll want to be there when the nostalgia starts flowing. Each episode will rival the feeling of taking out the cartridge from your Game Boy, blowing on it and popping it back in as we take you back to the 90s. Listen to, hey dude, the 90s called on the iHeart radio app, Apple Podcasts, or wherever you get your podcasts.
Starting point is 00:27:06 Because, I'll be there for you. And so will my husband, Michael. We know that Michael, and a different hot, sexy teen crush boybander each week to guide you through life, step by step. Kids, relationships, life in general can get messy. You may be thinking, this is the story of my life. If so, tell everybody, everybody, about my new podcast, and make sure to listen so we'll never, ever have to say, bye, bye, bye.
Starting point is 00:27:36 Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple Podcasts, or wherever you listen to podcasts. So what do we got here, Josh? We got population control is something that we've referenced before with our China One Child policy. Yeah, and we talked about why you would want to control a population. A huge group of people put a strain on resources. Sure.
Starting point is 00:28:06 When resources go away, you have resource conflicts, like in Darfur, again. Genocide, right? Sadly. There's all sorts of problems that come from too many people coming or living in one place because of the strain it puts on resources and resource allocation, right? And yeah, you can control the population, e.g., you know, state mandated reproduction.
Starting point is 00:28:31 Right, i.e., China. Right, and that actually works as China shows, although much to the detriment of some people. Thank you, Chuck, for that look. Not everyone thinks some people think we should add more people, though. Well, yeah, there's Japan. In other countries, there's a problem of population decline. So we talked about the strain people put on an area.
Starting point is 00:28:56 That's carrying capacity, which we've talked about before. That's also from Malthus. Right. That eventually human population is going to outstrip advances in technology or our resources and we're screwed. Right. On the other side is shrinking, population shrinking. And what's the problem with that?
Starting point is 00:29:15 Well, you don't want the population to shrink too much because you need those hands to go to work and to contribute to the economy and to grow the grain and sow the flower and all that good stuff. And apparently in Russia, Japan and Australia, they all have like little incentive programs to make little babies. Sure. How about that? Which is the way to go.
Starting point is 00:29:36 Remember John Fuller's famous quote? When he was pitching an article about that program in Russia and he was talking about Putin giving away a TV? Oh, yeah, that's right. That was really funny. Yeah. Have a baby, get a TV. I think you had to be there and check the reason why
Starting point is 00:29:51 some of these places are seeing a population shrink and are having to, I guess, give incentives to reproduce. Right. Started in about 1960. Birth control. That's so crazy that it had an effect. That much of an effect, that pronounced of an effect. Yeah.
Starting point is 00:30:09 Well, it would seem like it would though. I guess so because it's called birth control. Sure. You know. Yeah. Before that, it was called have as many babies as you possibly can. Right. It was called no control.
Starting point is 00:30:20 Right. All right. So clearly there's a lot of reasons to study people. Yeah. It's way more interesting than I thought it would be. There's a lot of stuff to study, too. Indeed. You can find out whether or not we're going to kill the planet
Starting point is 00:30:33 or whether people need to stop using contraceptives or whether what your chances are of Putin giving you a free TV. Right. It's all in there. It's all demographers know everything. All there for the taken. So when your frenzy friendly enumerator comes knocking on your door, don't chase them off your land with your dog or a gun.
Starting point is 00:30:55 Right. Let them in. Give them some lemonade. Maybe some cookies. Yeah. Well, check their laminate first. But oh yeah. Before you let them in.
Starting point is 00:31:01 COA check. Good going. And if you want to know more about population, you can read Grabenowski's great article on the site. Just type in population in the handy search bar at howstuffworks.com, which of course leads us to your listener mail. Josh, I'm just going to call this your turn at listener mail. Because I think you have to talk about some money.
Starting point is 00:31:25 Oh, is it? Give up. Yeah. I just I don't necessarily have too much listener mail per se. But I just wanted to give a shout out to a couple of fellow Toledoans, one who's a longtime resident and one who's a recent transplant. Uh-huh. Christopher is holding the fort down in Toledo for me.
Starting point is 00:31:41 Keeping it real? He has officially lobbied the congresswoman from Toledo to get me the key to the city. How awesome would that be? That happens. Yeah. So Marcy Keptor, if you're listening, I would like that very much. If you get a key to the city, we got to go for a ceremony. And I at least want to get like a key chain to the city.
Starting point is 00:32:01 Okay. And you can have the key. Okay, we'll see what we can do. So yeah, Christopher has officially petitioned her. He's suggested that I'm the third most famous Toledo in of all time. After Jamie Farr. Jamie Farr, Danny Thomas. Oh, yeah, yeah.
Starting point is 00:32:15 The great entertainer. Sure. And then me. And I was like, I think you're forgetting Katie Holmes. She's from Toledo. Is she? And he's like, no, you got her b. Yeah, no, Kate.
Starting point is 00:32:24 Kate Cruz, you mean? Oh, is it Kate Cruz now? Yeah, give me a break. So anyway, thanks a lot for the effort, Christopher, even if it doesn't come to fruition. If it does, you will get a firm handshake and a free friendlies Sunday of your choosing for me. I love friendlies. Yeah, we'll be going to friendlies if we go to Toledo.
Starting point is 00:32:41 For sure. And then I also want to say hi to Colin, who is a recent transplant, as I said, from Colorado, I believe. Who moves from Colorado to Toledo? He moved to Toledo to attend Bowling Green State University. Oh, okay, sure. Go Falcons. My brother went there.
Starting point is 00:32:59 And Colin did so in an 88 Dodge Colt. Right. That's having a couple of problems. One, the rear struts are completely detached. And the axle is holding on by a tread, he says. And the mechanics didn't want him to leave when he took it in for service. So they're like, you're going to die in this thing. And the other problem is it has ants, he says.
Starting point is 00:33:24 I've never heard of a car having ants. I had ants in the car once. Really? You can't get rid of them when they come in. Well, that's probably when you were living in the car, which was probably always parked on the ant hill. This is actually prior to that when I lived in the car. But yeah, no, it's a real problem.
Starting point is 00:33:39 And Colin's basically just put the bullet and said, well, I have ants in my car now. He loves his 88 Dodge Colt. He said he loves Toledo. He's enjoying it. He went to Tony Paco's, as I suggested. I got to try that one then. I also told him to go to Rusty's Jazz Cafe.
Starting point is 00:33:53 Nice. So it's authentic as it comes. Awesome. So, hey, Christopher. Hey, Colin, you guys enjoy yourselves. Be safe in Toledo. Heck yeah. Welcome down for the winter.
Starting point is 00:34:03 Go Mudhins. And thanks for writing in. And if you want to say hi to me or Chuck or both of us. Chuckers or Jerry. Right. Chuckers, Jerry, Chuck or I. I mean, Chuck or me, Chuck and me. Right.
