Just How Dirty are Public Restrooms?


Some people feel so terrified of the germs lurking in public bathrooms that they practically cover the entire stall in paper before they go. Others try holding it to avoid germ-infested public toilets. Good news germaphobes! A new study finds that public bathrooms contain no more germs than our own bathrooms. 

To understand the bathroom environment, researchers examined the microbial makeup of the floors, toilet seats, and soap dispensers at four different restrooms—two female and two male—at San Diego State University. First, the brave researchers cleaned the bathrooms; then they took samples from the various surfaces, first hourly and then daily for eight weeks. They analyzed the various germs found in each area. Unsurprisingly, they discovered that fecal bacteria flooded the bathrooms first. 

"When you flush the toilet it goes airborne and spreads these viruses throughout the bathroom," Michael Schmidt, professor and vice chair of the department of microbiology and immunology at the Medical University of South Carolina, told HealthDay. (Watching this video is not for the faint of heart.)

The cool, dry, oxygen-rich public bathroom turns out to be terrible at fostering bacterial growth, and fecal bacteria quickly die, accounting only for 15 percent of the germs in a public toilet. However, bacteria that thrive on skin tend to weather hostile environments better and these make up the majority of bacteria discovered in the WC.  

"You're constantly turning over this skin that's literally covered in microbes," Schmidt explained. 

Skin bacteria along with outdoor bacteria made up the majority, 68 percent, of the potty microbes. The researchers most commonly found Staphylococcus, a genus of gram-positive bacteria that reside on skin and mucous membranes. Most Staphylococcus remains harmless, though Methicillin-resistant Staphylococcus aureus, MRSA, can cause nasty infections and resists antibiotic treatment. The researchers also noticed a few viruses, such as human papillomavirus and herpes, but overall there were more bacteria than viruses in the loo.

But there’s more good news. Five hours after cleaning, the bacteria population establishes itself and it stays relatively stable, even after many, many uses.

But that still doesn’t mean it’s cool to skip a good hand washing:

“If you do not want to become colonized with someone else's stuff, you need to wash your hands to inactivate the microbes you've picked up," Schmidt said. "Hand sanitation is the human being's best way of protecting ourselves against diseases."

So go ahead, sit down on that public toilet seat. Just skip the hand dryer.

Big Questions
Why Is Holly a Symbol of Christmas?

Santa Claus. A big ol’ red-and-white stocking hung by the fire. Nativity scenes. Most classic Christmas imagery is pretty self-explanatory. Then there’s the holly, genus Ilex, which found its way onto holiday cards through a more circuitous route. 

Christmas is kind of the new kid on the block as far as holly symbolism is concerned. The hardy plant’s ability to stay vibrant through the winter made it a natural choice for pre-Christian winter festivals. The Roman feast of Saturnalia, celebrated at the darkest time of the year, celebrated the god of agriculture, creation, and time, and the transition into sunshine and spring. Roman citizens festooned their houses with garlands of evergreens and tied cheery holly clippings to the gifts they exchanged.

The Celtic peoples of ancient Gaul saw great magic in the holly’s bright "berries" (technically drupes) and shiny leaves. They wore holly wreaths and sprigs to many sacred rites and festivals and viewed it as a form of protection from evil spirits. 

Christianity’s spread through what is now Europe was slow and complicated. It was hardly a one-shot, all-or-nothing takeover; few people are eager to give up their way of life. Instead, missionaries in many areas had more luck blending their messages with existing local traditions and beliefs. Holly and decorated trees were used symbolically by new Christians, just as they’d been used in their pagan days.

Today, some people associate the holly bush not with the story of Jesus’s birth but with his death, comparing the plant’s prickly leaves to a crown of thorns and the berries to drops of blood. 

But most people just enjoy it because it’s cheerful, picturesque, and riotously alive at a time when the rest of the world seems to be still and asleep.

NOTE: Holly is as poisonous as it is pretty. Please keep it away from your kids and pets.

What Are the 12 Days of Christmas?

Everyone knows to expect a partridge in a pear tree from your true love on the first day of Christmas ... But when is the first day of Christmas?

You'd think that the 12 days of Christmas would lead up to the big day—that's how countdowns work, as any year-end list would illustrate—but in Western Christianity, "Christmas" actually begins on December 25th and ends on January 5th. According to liturgy, the 12 days signify the time in between the birth of Christ and the night before Epiphany, which is the day the Magi visited bearing gifts. This is also called "Twelfth Night." (Epiphany is marked in most Western Christian traditions as happening on January 6th, and in some countries, the 12 days begin on December 26th.)

As for the ubiquitous song, it is said to be French in origin and was first printed in England in 1780. Rumors spread that it was a coded guide for Catholics who had to study their faith in secret in 16th-century England when Catholicism was against the law. According to the Christian Resource Institute, the legend is that "The 'true love' mentioned in the song is not an earthly suitor, but refers to God Himself. The 'me' who receives the presents refers to every baptized person who is part of the Christian Faith. Each of the 'days' represents some aspect of the Christian Faith that was important for children to learn."

In debunking that story, Snopes excerpted a 1998 email that lists what each object in the song supposedly symbolizes:

2 Turtle Doves = the Old and New Testaments
3 French Hens = Faith, Hope and Charity, the Theological Virtues
4 Calling Birds = the Four Gospels and/or the Four Evangelists
5 Golden Rings = the first Five Books of the Old Testament, the "Pentateuch", which gives the history of man's fall from grace.
6 Geese A-laying = the six days of creation
7 Swans A-swimming = the seven gifts of the Holy Spirit, the seven sacraments
8 Maids A-milking = the eight beatitudes
9 Ladies Dancing = the nine Fruits of the Holy Spirit
10 Lords A-leaping = the ten commandments
11 Pipers Piping = the eleven faithful apostles
12 Drummers Drumming = the twelve points of doctrine in the Apostle's Creed

There is pretty much no historical evidence pointing to the song's secret history, although the arguments for the legend are compelling. In all likelihood, the song's "code" was invented retroactively.

Hidden meaning or not, one thing is definitely certain: You have "The Twelve Days of Christmas" stuck in your head right now.
