(Way More Than) Everything You Wanted To Know About Guinea Pigs

Original image

Let's get this straight. They're not pigs. They're rodents. And they're not from Guinea, either, so the name is just downright misleading. Cavies (cavia porcellus), also known as guinea pigs, are tame, become accustomed to handling, and rarely bite, making them not only ideal pets but ideal lab animals. And in some cases, a crunchy snack or homeopathic diagnostic tool—especially when the pig is drunk. Here's some delicious peeg trivia the next time you need to impress the boss or in-laws.

They Used to be HUMONGOUS

Eight million years ago, the ancestor of the guinea pig was the buffalo-sized 1,545-pound rodent Phoberomys pattersoni. It lived a semi-aquatic life in the ancient Orinoco delta in northern Venezuela, frolicking amongst lion-sized marsupial cats and three meter long crocodiles.

High-Profile Owners

Queen Elizabeth I is purported to have owned a guinea pig, starting the trend of keeping guinea pigs as a pet. Theodore Roosevelt's family raised guinea pigs. In letters, he complained about being forced to babysit them.

Crepuscular!

Guinea pigs are crepuscular—mostly active during twilight hours. This is due to their domestication; subdued indoor lighting has led them to prefer neither direct sunlight nor total darkness.

Yum Yum Yum Guinea Pig in My Tum

Once only consumed by ancient royalty and elite or reserved for ceremonial meals, a dish of guinea pig, or Cuy, has gradually become common in Peruvian, Ecuadorian, and Bolivian diet. The guinea pig, native to South America, has meat that is high in protein and low in fat and cholesterol, similar to rabbit or the dark meat on chicken.

There isn't much space to raise cattle in the mountains, so modern day Andean Indians and Peruvians often raise guinea pigs as a food or income source. They will keep eight to fifteen guinea pigs at a time for food, although some families may have as many as forty or fifty running amok in their home. With the exception of the occasional egg, guinea pig meat is often the only source of animal protein available to Andean Indians.

During World War II, the government encouraged Italian peasants to raise guinea pigs to supplement their meat rations, but this campaign did not go over very well.

A recipe for cooking guinea pig can be found here, but be warned that you may need to buy and cook three or four at a time in order to feel full. Also, be warned: guinea pig meat is illegal in several places, including California.

Avast, That Peeg Thar has Scurvy

Like humans, guinea pigs are one of the few mammals that cannot make or store their own Vitamin C (ascorbic acid). Because guinea pigs do not have L-gulonolactone oxidase (GULO), an enzyme that produces Vitamin C, guinea pigs have to get all of their vitamin C from food or "“ again,like humans "“ they will die from scurvy. The only other known animals that cannot synthesize their own Vitamin C are primates, fruit eating bats, and a specific species of bird and trout, respectively.

When scientists study the effect of Vitamin C on humans, they almost always use guinea pigs as the test animal. Vitamin C overdose has been correlated to osteoarthritis, and guinea pigs develop knee arthritis in a manner similar to humans.

Male guinea pigs can mate with as many as forty guinea pigs, although the common ration is one male to seven females. In 2000, BBC reported on Sooty, a Welsh guinea pig who knocked up 24 females over the course of 2 days and fathered 42 babies. [Photo credit.]

Cavies as Ceremonial Mediums and X-ray Machines

The guinea pig was regarded as an important divination tool. Incan haruspices would open the animals with their fingernails and inspect the entrails to prognosticate. Even to this day, guinea pigs are sometimes used in rural areas as sacrificial offerings or for fortune telling.

In addition, curanderos, South American folk healers, use guinea pigs as a diagnostic and healing tool. A live guinea pig is rubbed over the body of the sick patient, and the pig's reaction is used to gauge the illness. If the pig dies during this rubbing procedure, it is generally considered a bad sign. Afterwards, some curanderos will split open the guinea pig to examine its internal organs and arrive at a diagnosis, or kill the guinea pig in order to destroy the disease. Modern day takes on this practice include feeding the guinea pig beer (making the guinea pig's healing powers more potent) and adorning it with ribbons before giving the patient a rub down. The guinea pig is then set free, taking the disease with it.

High Maintenance Nakedness

Originally bred for dermatological laboratory research and chemical testing, these hypoallergenic guinea pigs have a weaker immune system and resemble baby hippos. They are very easily sunburned, sensitive to the cold, and their delicate rumps require frequent moisturizing with lotion. [Photo credit.]

25 Things You Should Know About Tucson
Original image

The west is still wild in Tucson. Surrounded by breathtaking mountains, Arizona’s second-largest city attracts artists, astronomers, outdoorsy types and at least one rare cat. Read on for more Tucson trivia.

1) Some of the earliest evidence of corn cultivation in North America comes from Pima County, Arizona, where Tucson is located. Archaeologists have recovered kernels estimated to be 4000 years old within 60 miles of the city.

2) Towering above the downtown area is an iconic mountain called Sentinel Peak. Look at it from a distance and you may notice that the base is darker than the summit. The native Tohono O’odham people called this landmark Ts-iuk-shan—which is a corruption of their word for “black base.” Spaniards later turned Ts-iuk-shan into Tucson.

3) On March 20, 1880, a passenger train rolled into Tucson for the first time. Mayor R.N. Leatherwood sent out telegrams to dignitaries to publicize the occasion, writing to Pope Leo XIII that the railroad now linked "this ancient and honorable pueblo" with the rest of the Christian world. Newspapers began calling Tucson “the A. and H. Pueblo,” which gradually shrunk to its current nickname, “the Old Pueblo.”

4) If you’re a stargazer, Tucson is one of the best spots in the U.S. for astronomy. In 1972, Pima County enacted a “dark sky” code to regulate the brightness and number of outdoor bulbs in an effort to help local observatories like one at Kitt Peak. Now Tucson suffers from far less light pollution than most cities do, allowing stars and planets to shine through the darkness.

5) Above Broadway Boulevard, you can walk through the belly of a giant metal snake. A covered bridge for pedestrians and cyclists, this serpentine structure is designed to look like a diamondback rattlesnake, whose gaping jaw and fangs form the entrance.

6) By day, it looks like a big plastic doughnut. But after sundown, the solar-powered Desert O sculpture lights up in an array of vibrant colors. The ring, owned by the city of Tucson, is 6 feet in diameter and uses LED lights to create a brilliant display with a different color combo for every night of the week.

7) In 1970, then-mayor Jim Corbett called Tucson's East Speedway Boulevard the "ugliest street in America." At the time, it was enveloped by garish billboards that obscured the city's beautiful vistas. Then Life magazine ran a two-page photo of the forest of road signs and advertisements. The embarrassing spotlight led to Tucson's sign code, passed in the 1980s, which gradually limited billboards and tacky signage.

8) According to Guinness World Records, Davis-Monthan Airforce Base in Tucson has the largest aircraft repair shop and storage facility on Earth. Covering 2600 acres, it could house 4200 aircraft and 40 aerospace vehicles at one time, while still leaving room for 350,000 production tools.

9) In 2013, a new species of scorpion was discovered in the Santa Catalina Mountains, which are visible from downtown Tucson. Biologist Rob Bryson Jr. discovered the species in the Santa Catalinas' "sky islands"—isolated mountaintop habitats known for their biodiversity.

10) Cyclists should consider dropping by on the last Saturday before Thanksgiving for El Tour de Tucson, Arizona's largest and longest-running cycling event. The series of races attracts more than 9000 bike enthusiasts per year and usually raises about $2 million for local charities.

11) Hugo O’Conor, an Irish colonel in the Spanish army, is regarded by some as the founder of Tucson. Although a Spanish mission had been operating in present-day Tucson since 1692, and Native American communities before that, O’Conor arranged to have a military base for Spain's army set up on the site in 1775, resulting in a population boom for the city. O'Conor's red hair and courage in battle gave him the nickname “The Red Captain.”

12) The United States Handball Association Hall of Fame is located on North Tucson Boulevard.

13) Five years after peace was declared in the Mexican-American War, the U.S. bought the lower third of Arizona, which included Tucson, from Mexico. The $10 million transaction, known as the Gadsden Purchase, was finalized in 1854 and added a 30,000-square-mile territory to the United States. The expansion allowed Gadsden, a railroad promoter, to build a transcontinental railroad through the new territory.

14) One of the largest rock shows in the country, the Tucson Gem and Mineral Show attracts around 50,000 people annually. In addition to hosting gemstone scholars and dealers, the annual convention has exhibited the most dazzling rocks in existence—like the Hope diamond, lunar rocks collected by NASA astronauts, and the eye-popping Logan sapphire.

15) The Arizona State University Sun Devils and the University of Arizona Wildcats have a longstanding rivalry that dates back to their first meeting in 1889. Each year, the teams compete for the Territorial Cup, the oldest rivalry trophy in college football. The Wildcats play regular home games in their 56,000-seat stadium in midtown Tucson.

16) Speaking of the University of Arizona, it was founded in 1891—21 years before Arizona achieved statehood.

17) Tucson's world-class culinary scene was recognized by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) in 2015 as a “Capital of Gastronomy.” Only 18 cities around the world have been given this title, and no other American city has cracked the list yet. Jonathan Mabry, a historic preservation officer in Tucson, filed the application for the city. “There are more heritage foods grown within 100 miles of Tucson than any other city in North America,” he told Smithsonian.com.

18) The Fourth Avenue Underpass doubles as a one-of-a-kind photo gallery. Roughly 7000 tiles bearing black and white portraits of 21st-century Tucsonans line the walls.

19) Four national flags have flown over the Old Pueblo. Spain ruled Tucson and the rest of Mexico until 1821. Then Mexico itself took over, but sold Tucson and much more territory to the United States in 1854 (see #13). When the Civil War broke out, the city joined the Confederacy and flew the Confederate flag from February to June 1862. Then Union forces, bearing the American flag, took the city back

20) Tucson is the oldest incorporated city in Arizona (and has been since incorporating in 1877).

21) For a few weeks in 1933, radio listeners in Tucson could enjoy a local show hosted by a very young Ray Bradbury. At age 12, he landed a gig at KGAR reciting comic strips on the air every Saturday night. “My pay was free tickets to see King Kong, Murders in the Wax Museum, and The Mummy,” he later reminisced. “You can’t do any better than that.”

22) El Charro Café is the oldest Mexican restaurant in the U.S. continuously operated by the same family. It may also be the birthplace of the chimichanga. As the legend goes, they were invented by Monica Flin, who established El Charro in 1922. She once flipped a burrito right into the fryer, splattering oil everywhere. Since kids were within earshot, she resisted the urge to curse and yelled “chimichanga,” a slang word that means thingamajig, instead.

23) The Mini Time Machine Museum of Miniatures is truly larger than life. A gallery of scale models, it boasts more than 300 tiny room boxes and houses. Some examples predate the Revolutionary War.

24) Downtown, a street known as Calle Carlos Arruza honors one of the greatest bullfighters in history, Mexican-born Carlos Arruza, whose nickname was El Ciclon (The Cyclone). According to historian David Leighton, Calle Carlos Arruza is one of the very few streets—possibly the only street—in the U.S. named after a bullfighter.

25) Only two non-captive jaguars, the largest cats in the New World, are known to reside within the U.S. One of them, nicknamed El Jefe, is a Tucson celebrity. Discovered in 2011, he can be found stalking the Santa Rita Mountains 25 miles south of the city. Jaguars are a near-threatened species: biologists estimate that about 15,000 are left in the wild.

The Night the Brat Pack Was Born
Original image
Columbia/TriStar

If Emilio Estevez had opted to pay for his movie ticket, the Brat Pack might never have been born. It was spring 1985, and Estevez—then the 23-year-old co-star of St. Elmo’s Fire—was being profiled in New York Magazine. The angle was that Estevez had just signed a deal to write, direct, and star in his own feature, That Was Then... This is Now, an opportunity that was rarely afforded to young Hollywood talent. Estevez was two years younger than Orson Welles was when he performed similar duties for 1941’s Citizen Kane.

That youthful exuberance was on display as New York writer David Blum followed Estevez in and around Los Angeles for several days gathering material for the story. With Blum in tow, Estevez decided that he wanted to catch a screening of Ladyhawke, a fantasy film starring Matthew Broderick. For reasons not made entirely clear, he preferred not to have to pay for a ticket. According to Blum, Estevez called the theater and politely asked for free admission before entering an 8 p.m. screening.

It's likely Estevez was just having a little fun with his celebrity. But to Blum, it was indicative of a mischievous, slightly grating sense of entitlement. Blum’s assessment was that Estevez was acting “bratty,” an impression he felt was reinforced when he witnessed a gathering of other young actors at LA’s Hard Rock Cafe for the same story.

What was supposed to be a modest profile of Estevez turned into a cover story declaration: Hollywood’s “Brat Pack” was here, and they had decided to forego the earnest acting study preferred by their predecessors to spend their nights partying instead.

The day the story hit newsstands, Blum received a call from Estevez. “You’ve ruined my life,” he said.

Blum’s label had its roots in the Rat Pack of the 1960s, so named for the carousing boys' club led by Frank Sinatra, Dean Martin, and Sammy Davis Jr. Whether it was accurate or not, the performers developed reputations for squeezing every last drink, perk, and joke they could out of their celebrity well into middle age.

That dynamic was on Blum’s mind when New York dispatched him to cover Estevez. After he arrived in California, Blum took note of the fact that a tight cluster of actors seemed to have formed a group, both on- and off-screen. Estevez was close friends with Rob Lowe and Tom Cruise, and all of them appeared in 1983’s The Outsiders; Lowe and Estevez were co-starring in St. Elmo’s Fire, a coming-of-age drama that also featured Andrew McCarthy and Judd Nelson; Estevez and Nelson gained a lot of attention for 1984’s The Breakfast Club.

To Blum, Estevez was more than just a multi-hyphenate; he appeared to be the nucleus of a group that spent a lot of time working and playing together. And in fairness to Blum, Estevez didn’t dissuade the writer from that take: Fearing he was coming off as too serious in the profile, Estevez asked Lowe and Nelson to hang out with him at Los Angeles’s Hard Rock Cafe so Blum could see the actor's lighter side.

Nelson would later recall that he felt uneasy around Blum. “Why is this guy having dinner with us?” he asked Estevez. Lowe, meanwhile, was busy flirting with women approaching their table. The group later went to a "punk rock" club, with a Playboy Playmate tagging along.

As celebrity hedonism goes, it was a tame evening. But Blum walked away with the idea that Estevez was the unofficial president of an exclusive club—attractive actors who were soaking up success while idling late into the night.

Blum returned to New York with a different angle for his editors. He wanted to capture this “Brat Pack,” a “roving band” of performers “on the prowl” for good times. Although the magazine had just run a cover story about a teenage gang dubbed “the wolf pack” and feared repetition, they agreed.

As far as Estevez and the others were concerned, Blum was busy executing a piece on Estevez’s ambitions as a writer and director. When Estevez, Nelson, and Lowe appeared on the cover—taken from a publicity still for St. Elmo’s Fire—with his newly-coined phrase, they were horrified.

Blum began getting calls from angry publicists from each of the actors mentioned in the article—and there had been a lot of them. In addition to Estevez, the de facto leader, and lieutenants Lowe and Nelson, Blum had dubbed go-to John Hughes geek Anthony Michael Hall the “mascot”; Timothy Hutton was said to be on the verge of excommunication for his film “bombs”; Tom Cruise, Sean Penn, Nicolas Cage, and Matt Dillon were also mentioned.

To the actors, the effect was devastating. Independent of how they spent their free time, all of them were pursuing serious careers as performers, with producers, directors, and casting agents mindful of their portrayal in the media. Being a Brat Packer was synonymous with being listless, or not taking their craft seriously.

Nelson recalled the blowback was immediate: Managers told him to stop socializing with his friends for fear he’d be stigmatized as unreliable. “These were people I worked with, who I really liked as people, funny, smart, committed to the work,” he said in 2013. “I mean, no one was professionally irresponsible. And after that article, not only [were] we strongly encouraged not to work with each other again, and for the most part we haven’t, but it was insinuated we might not want to be hanging out with these people.”

Universal Pictures

Some of the actors went on The Phil Donahue Show to criticize the profile, asserting that their remarks to Blum had been off-the-record. (Blum denied this.) Lowe told the media that Blum had “burned bridges” and that he was “no Hunter S. Thompson.” Andrew McCarthy called Blum a “lazy … journalist” and found the idea of an actor “tribe” absurd—he had never even met Anthony Michael Hall.

Unfortunately, the name stuck. “Brat Pack” was infectious—a catch-all for the kind of young performer emerging in the ‘80s who could be seen in multiple ensemble movies. While Blum would later express regret over the label, it’s never quite left the public consciousness. In 2005, Universal released a DVD boxed set—The Breakfast Club, Weird Science, and Sixteen Candles—as The Brat Pack Collection.

Nelson, Estevez, and Lowe never again appeared in a movie together. “Personally, the biggest disappointment about it is that ‘Brat Pack’ will somehow figure in my obituary at [the] hands of every lazy and unoriginal journalist,” Estevez told a reporter in 2011. “Warning: My ghost will come back and haunt them.”

Nelson was slightly less forgiving. In a 2013 podcast, he chastised Blum for his mischaracterization of the group of young actors. “I would have been better served following my gut feeling and knocking him unconscious.”
