Over or under? Surprisingly, there actually is a 'correct' way to hang a toilet paper roll.
Let's settle this silly-but-surprisingly-heated debate once and for all.

Should you hang the toilet paper roll over or under?
Humans have debated things large and small over the millennia, from the democracy to breastfeeding in public to how often people ought to wash their sheets. But perhaps the most silly-yet-surprisingly-heated household debate is the one in which we argue over which way to hang the toilet paper roll.
The "over or under" question has plagued marriages and casual acquaintances alike for over 100 years, with both sides convinced they have the soundest reasoning for putting their toilet paper loose end out or loose end under. Some people feel so strongly about right vs. wrong TP hanging that they will even flip the roll over when they go to the bathroom in the homes of strangers.
Contrary to popular belief, it's not merely an inconsequential preference. There is actually a "correct" way to hang toilet paper, according to health experts as well as the man who invented the toilet paper roll in the first place.
First, let's be clear about what we're even talking about here with a visual. In the image below, left is "over" and right is "under."

So which one is the right way? According to health experts, "over" is the way to go.
"One key to maintaining a hygienic washroom is minimising contact between people and surfaces," Dr. Christian Moro, associate professor of health sciences and medicine at Bond University on Australia's Gold Coast, told Australian Broadcasting Corporation. "Depending on the type of roll holder, [hanging the toilet paper "over"] often lowers the chance that a user will touch the wall behind when fishing for paper, leaving germs behind on that surface which can be spread to the next user."
Picture it: Grabbing the end of the toilet paper when it's hung "over" means you only touch the part of the toilet paper you're going to use. When it's "under," you sometimes have to fish for it or scrape your fingers on the wall in order to grab the loose end. In addition to whatever might be on people's hands already, think about all the people who wipe twice, potentially transferring fresh fecal matter or other bacteria to the wall on the second pass, which then get picked up by other people who inadvertently touch that wall when trying to grab their TP.
Theoretically, we all should have become better hand washers during the pandemic, scrubbing with soap for the full 20 seconds it takes to remove bacteria. But I wouldn't be willing to bet on it.
And touching any surface in a bathroom is pretty nasty, according to a study from the University of Colorado. As Inc. reported: "Using a high-tech genetic sequencing tool, researchers identified 19 groups of bacteria on the doors, floors, faucet handles, soap dispensers, and toilets of 12 public restrooms in Colorado — six men’s restrooms and six women’s restrooms. Many of the bacteria strains identified could be transmitted by touching contaminated surfaces."
Bacteria means things like e.coli, which is a common source of food poisoning and one of the most common bacteria found on bathroom surfaces in the study. If you've ever had a bout of food poisoning, I'm sure you'll agree that a toilet paper roll hanging preference isn't worth risking it.
But sanitary health concerns aren't the only argument for the "over" camp. After all, the original patent for the toilet paper roll, issued in 1891, clearly shows the TP in the "over" position. Thank you for the clarity right from the get go, Mr. Wheeler.

The toilet paper roll was patented by Seth Wheeler in 1891.
Now, before the "under" folks come running with their pitchforks, there are some understandable exceptions to the "over" rule. Namely: cats and kids.
If you have a furry friend or a tiny toddler who likes to unroll the toilet paper roll, "over" makes it super fun for them, while "under" stops them in their tracks. For many people, cats and kids are the primary motivator of their TP hanging habits.
That doesn't change the fact that "over" is actually the "correct" way to hang toilet paper according to health science and the inventor's intention, of course, but "under" is certainly preferable to having a pile of TP on the floor.
Now go forth, do that with information as you will, and try to make peace with your over vs. under rivals.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
