Send us a text Psychoactive substances have been ingested by human beings for millennia. But for a few decades at the end of the 20th century, many were banned in the U.S. as part of a cultural backlash manifesting itself in the disastrous War on Drugs. Now that’s slowly changing, as the medical industrial complex reconsiders the use of psychedelic drugs like MDMA, psilocybin, and LSD for treating depression, anxiety, PTSD, substance use disorders, and much more. Joe and Mark discuss the hist...
Send us a text A few years ago, we all started hearing about how gas ranges, which have been popular in our country for at least a century and are favored by professional chefs, were dangerous to our health and should be replaced by electric or induction cooktops. That revelation begs a couple of obvious questions about how such an unsafe appliance became so ubiquitous in the first place, and why we’re only hearing about its dangers now. Mark and Joe recount how natural gas became the go-to p...
Send us a text Back in its early days, this podcast explored the cultural and economic juggernaut that is Christmas. Time now to take a gander at Halloween. It’s unique among American holidays in that it’s neither religious nor patriotic nor sentimental, yet it’s hugely and increasingly popular for kids and grown-ups alike. How did that come to be? Attention, trick-or-treaters—Joe and Mark leave this sweet offering for you: a tale about how Halloween’s centuries-long metamorphosis from pagan ...
Send us a text Overshadowed by all the anti-immigrant rhetoric afflicting our country today are wonderful stories of non-human immigration, such as the ones about how certain foods made their way from the New World to the Old World. Take potatoes and tomatoes, for example. They’re staples of Irish and Italian cuisine, respectively, but neither was native to those countries—both originated in the Americas. Mark and Joe tell the story of how these two hardy pioneers with humble roots in Mesoame...
Send us a text Based on recent proclamations from the MAGA government and the zealotry that some of its partisans have for the American flag, you’d never guess that flag worship was really not a thing in the United States for a very long time. Most Americans in the first half of the 19th century had little to no knowledge of the Stars and Stripes; that is, until the Civil War changed everything. Joe and Mark discuss Old Glory’s journey from military banner to object of near-religious venerati...
Send us a text You may have noticed that there are a lot of very old people clinging to positions of authority, from our current president (79 years old) to our former president (82 when he left office) to other leaders in politics, business, and culture. Why won’t these folks leave the stage and let their younger colleagues step into power? Is this state of affairs good or bad for our society? Mark and Joe trace the history of gerontocracy, its role in feeding the alienation of younger gener...
Send us a text In The Social Contract, the philosopher Jean-Jacques Rousseau suggested that democracy was feasible only in smaller polities where the citizens have shared common interests. What might Rousseau have to say about the current-day United States, with its sprawling national government and a citizenry that can’t even agree on basic facts? Joe and Mark revisit their college classrooms to discuss Rousseau’s concept of the general will, whether it’s achievable in a large country, or wh...
Send us a text When visiting a few cemeteries recently, Joe was struck by how clean and well-maintained but desolately empty they were. That prompted him to ask Mark about the economic viability of cemeteries and whether they were becoming relics of a bygone age as increasing numbers of people opted for cremation. Mark and Joe discuss the history of cemeteries and prospects for the mortuary industry. Turns out it isn’t just whistling past the graveyard to think that our repositories for death...
Send us a text Water seems to many of us like an unlimited resource, what with oceans covering 71% of the Earth’s surface. But less than 3% of the world’s water is fresh, and nearly a third of that is groundwater, found deep beneath the surface in aquifers between soil and rock. Many of the world’s aquifers are drying up as we over-pump them for irrigation, drinking water, and industrial uses. Does the depletion of groundwater pose an existential threat to humanity? Joe and Mark slosh around ...
Send us a text What do the following household items have in common: A jar of aspirin; a tube of toothpaste; a clear plastic bottle; a package of KN-95 masks? Answer: they all expire on a certain date. Indeed, our homes are full of stuff we’re supposed to throw away long before we’re done with it. But do these products truly go bad, or are their producers planning their obsolescence so you’ll buy them again and again? Don’t mind Mark and Joe as they forage through your medicine cabinet, pantr...
Send us a text For decades, American suburbia has resembled one continuous green lawn stretching across property boundaries in every direction. Indeed, lawns are part of the fabric of American life. When was it that we all decided to put grass around our homes, and why? Joe and Mark ramble through America’s iconic yardscape to dig up the history of grassy lawns, why they took hold here, and whether recent anti-lawn proclivities will eventually take root or be RoundedUp and killed like yesterd...
Send us a text Bullet trains have been a major component of transit systems in places like Japan, China, and Europe for decades. Why hasn’t high-speed rail taken root in the supposedly forward-thinking United States? Mark and Joe set off on a journey of discovery through issues like inadequate infrastructure, population density, and the usual economic and political obstacles before reaching its terminus in America’s ongoing, dysfunctional love affair with cars. Daunting as these challen...
Send us a text To meet the increased demand for carbon-free electricity that might mitigate the climate crisis that is already upon us, nations the world over are reconsidering nuclear energy. Mansplaining listeners of a certain age remember the No Nukes movement that gained steam after frightening meltdowns at Three Mile Island and Chernobyl. What they may not realize is that nuclear power remains an important piece of the world’s energy portfolio. Joe and Mark assess nucle...
Send us a text Recent estimates are that the United States has a shortage of housing volume of 4-7 million homes. A problem of that scale doesn’t happen overnight and involves decades of neglect and inaction. With the chronic lack of housing likely to be a major issue for the foreseeable future, public policy experts have been brainstorming about potential solutions, and a few have dusted off an idea that’s older than the Republic: a tax on the value of land without regard to the buildi...
Send us a text Like its cousin AGI, quantum computing, which harnesses the quantum states of subatomic particles to perform impossibly difficult computations at lightning speed, is a new-ish technology that many of its proselytizers believe is thisclose to reality. The “quantum supremacy” of this new technology over classical computing promises stunning breakthroughs in areas as disparate as drug development, materials science, weather forecasting, and cybersecurity. Is it for real, tho...
Send us a text The New York Yankees’ recent relaxation of half-century-old rules about facial hair got Joe to thinking about dress and codes generally. Why do they exist? Where do they come from? Mark takes Joe on a historical tour of dress codes, from ancient Rome and China through medieval Europe and Tudor England, ending in the modern era of school uniforms and casual Fridays. As our heroes discover, attire-related restrictions are less about affirming people than a...
Send us a text You know them by their brand names, like Ozempic, Trulicity, or Mounjaro. They're the GLP-1 receptor agonists that were originally formulated for Type 2 diabetes but have caused a revolution in the treatment of weight loss. As more research rolls in, they’re also looking like game-changers for treating conditions as far-ranging as heart disease, dementia, and substance use disorders. Do they represent a medical breakthrough on the level of penicillin, or are they too good to be...
Send us a text State lotteries are a 12-figure business in the US of A. Americans spend more money on lottery tickets than on books, video games, recorded music, movie and sports tickets combined. Of course, lottery revenue is allocated to public goods like schools and parks, but it’s a double-edged sword, as lotteries are disproportionately funded by the poorest third of households, i.e., the people who can least afford them. Mark takes Joe through the checkered history of lotteries, their p...
Send us a text Here are a couple sobering numbers: The typical American has only $8,000 in the bank, and the median savings for the age cohort approaching retirement is only $120,000. Neither is anywhere close to adequate. Might a fiscal cliff be approaching for millions of retirees? Joe and Mark do a deep dive into the scary numbers outlining Americans’ financial distress and declining optimism about the future, consider some reasons how and why we became so uniquely bad at saving, and ponde...
Send us a text You’ve probably used a map app like Google Maps, Apple Maps or Waze to help you get from Point A to Point B as quickly as possible. But did you ever wonder how they work? Did you ever wonder whether we should slavishly follow their directions or be skeptical and consider external factors like our own prior driving experience? Well, wonder no more. Mark and Joe take the fastest route that starts with paper maps, brings them past an obscure mathemati...
