The Debunker: Do People Breathe in Oxygen and Breathe Out Carbon Dioxide?

by Ken Jennings

In addition to his day job as Woot's full-time "Debunker," Jeopardy! wunderkind Ken Jennings moonlights as an author of books, and this month he has a new one in stores. It's the fifth in his Junior Genius series, this time chock-full of amazing facts about The Human Body. To mark the occasion, he'll spend all of February debunking anatomical anachronisms and medical misinformation for us. Finally: the inside scoop about our own insides.

The Debunker: Do People Breathe in Oxygen and Breathe Out Carbon Dioxide?

Well, okay. Yes, you do breathe in oxygen and breathe out carbon dioxide, which is why you're still alive. Fine. But you also breathe in plenty of carbon dioxide and breathe out plenty of oxygen. It's a lot more complicated than the diagram you remember from third grade where the people are pumping out carbon dioxide and the trees are pumping out oxygen.

The Debunker: Do People Have Five Senses?

The Debunker: Do People Have Five Senses?

"There is no sixth sense in addition to the five enumerated: sight, hearing, smell, taste, touch," wrote Aristotle in his landmark work De Anima, or On the Soul. And for the next two thousand years, Western civilization stuck with this view: five senses, period. "Sixth sense" became shorthand for some rare, ephemeral, unclassifiable-by-science gift, like telepathy.

The Debunker: Is the Heart on the Left Side of Your Body?

With Valentine's Day coming up, we're all more aware than usual that there's no greater mystery than the human heart. But it would probably surprise you how little most people know about their own heart. Including where it even is.

The Debunker: Does Lactic Acid Make Your Muscles Tired?

The Debunker: Does Lactic Acid Make Your Muscles Tired?

If you ever went to a gym- or a gym class - in the late 20th century, you probably heard this helpful exercise "fact": the reason why muscles get sore and give out, my fifth grade P.E. teacher assured us, is a chemical called lactic acid. Yup, the same stuff that makes sour milk sour and yogurt yogurt-y. It's in the body as well, and when it's produced by active muscles, it eventually causes fatigue and then soreness. Burning, overworked muscles were a sign of lactic acid building up, a warning sign from your body that you need to dial it back a bit.

The Debunker: Does the Word "Gringo" Come from Songs of the Mexican-American War?

by Ken Jennings

In January, we stand at the frontier of a new year. Obviously, there's no better month to remember that other mythic uncharted territory, the American frontier of the Old West! In the Western classic The Man Who Shot Liberty Valance, a newspaper editor famously says, "This is the West, sir. When the legend becomes fact, print the legend." But that attitude has led to a lot of frontier lore that's just plain loco. We've asked Jeopardy gunfighter Ken Jennings to separate fact from legend--and print only the facts. Let's see if he can clean up this town.

The Debunker: Does the Word "Gringo" Come from Songs of the Mexican-American War?

Etymology rule of thumb: as well-known stories about word origins become more and more "fun" and improbable, the likelihood that they are true approaches zero. Take the word gringo, a scornful Spanish slang word for anglo types. According to an oft-told story, gringo dates back to the Mexican-American War, when American soldiers were frequently overheard singing marching songs like "Green Grow the Rushes" and "Green Grow the Lilacs." Gringo is actually a corruption of the words "green grow," this theory would have you believe.

The Debunker: Did Jesse James's Gang Rob from the Rich and Give to the Poor?

Let's see if he can clean up this town.

The Debunker: Did Jesse James's Gang Rob from the Rich and Give to the Poor?

In 1882, the famed outlaw Jesse James was shot in the back by one of his gang members, Robert Ford (Brad Pitt and Casey Affleck, if you saw the movie). The shooting was immortalized in the folk song "Jesse James," which takes a strongly pro-Jesse/anti-Ford stance. Robert Ford is dismissed as a "dirty little coward," while Jesse James is lauded because "he stole from the rich and he gave to the poor." "He'd never see a man suffer pain," insists the star-struck balladeer. "He'd never rob a mother or child." The song, covered by everyone from Woody Guthrie to Bruce Springsteen, has cemented in the public mind the notion that Jesse James was a colorful do-gooder. Sure, maybe he was an outlaw, but the noble Robin Hood kind! A likable rascal!

The Debunker: Did Cowboys Wear Ten-Gallon Hats?

Real talk: no hat can hold ten gallons, not even Pharrell's. Your average Stetson has a maximum carrying capacity of three quarts, just 7.5% of what's advertised. Not sure why you'd want to carry liquid in your hat, cowpokes, but "let the buyer beware" is all I'm saying.

The Debunker: Was There a Gunfight at the O.K. Corral?

The Debunker: Was There a Gunfight at the O.K. Corral?

If Westerns were accurate, they'd be the most sedate movie and TV genre ever. They'd make Errol Morris documentaries look like Errol Flynn movies. They'd make BBC costume dramas look like Sons of Anarchy. That's because, despite what Hollywood would have you believe, violence was uncommon in the "Wild" West. Six-shooters were too inaccurate and ammo too expensive for precision dueling at high noon. Most frontier towns were safe, quiet places where visitors had to surrender firearms to the sheriff upon arrival. Don't tell the NRA.

The Debunker: Did Someone Else Write the Works of Shakespeare?

by Ken Jennings

If you're an anglophile, a lover of all things British, then this time of year must be like Christmas for you. Well, it's real Christmastime as well, but you know what I mean, right? If you have a soft spot for Dickensian carolers, candlelit mince pies, snow-covered country villages, special episodes of inexplicably popular TV shows like Downton Abbey and Doctor Who... well, in December, we all become a tiny bit British, don't we? But not everything we think we know about life across the pond is strictly "pukka." We've enlisted Sir Kenneth Jennings, VC, GBE, DJO (Distinguished Jeopardy! Order) to help us "mind the gap" between fact and fiction when it comes to Merrie Old England.

The Debunker: Did Someone Else Write the Works of Shakespeare?

It was Francis Bacon! Or Christopher Marlowe. Or could it have been Edward de Vere, the 17th Earl of Oxford? With all the hype that alternate theories of Shakespeare authorship have received lately (including Anonymous, a big budget movie by Independence Day director and Shakespeare skeptic Roland Emmerich) you'd be forgiven for thinking that this is an actual academic controversy. Could someone else have written the plays of Shakespeare? It would certainly be big news if the most celebrated writer in the history of the language--of any language maybe--were revealed as a fraud.

The Debunker: Does the Gulf Stream Keep Britain Warm?

The Debunker: Does the Gulf Stream Keep Britain Warm?

Travel due west from the United Kingdom, and what's the first U.S. state you'd hit? Virginia? Massachusetts? Maine, maybe? A quick look at a world map will probably surprise many: the whole of the British Isles lies to the north of the northernmost point in the contiguous 48 states. Due west from London, you'd reach the New World at the subarctic forest of southern Labrador, Canada. The only state you could hit traveling west from anywhere in the U.K. is actually Alaska! In short, Britain is a lot farther north than a lot of people think.
