Plain radiographs showed 11 nails penetrating into his brain. His detailed history presented a diagnosis of PARAN0ID SCHlZ0PHRENlA, and the patient confirmed that he had hammered a nail into his head each week for the past 11 weeks in order to rid him of evil.

The nails were removed with the patient under general anesthesia, and he made an uncomplicated recovery with no neurological deficits.
The curiosity to look at medical procedures or conditions isn’t new.
Long before the internet existed, crowds gathered to watch public surgeries in the anatomical amphitheaters of the Renaissance. Here, public dissections took place several times a year to see what many believed were the “secrets of nature revealed by God.”
For an entrance fee, people could watch doctors conducting an autopsy on the body of an executed criminal. Surgery was pure theatre, literally.
As Julie V Hansen describes, “In the anatomical theater, which was lit by scented candles to augment the dim light drawn from windows and sometimes featured music played by a flutist…they took on a festive and theatrical atmosphere.”

Around the 18th century, the operating theater at Jefferson Medical College in Philadelphia was famously nicknamed “the pit,” a reference to the space where orchestra musicians typically sit during performances.
Surgery turned certain doctors into public attractions. Scottish surgeon Robert Liston was history-of-operating-theaters/1" rel="noopener noreferrer" target="_blank">nicknamed “the fastest knife in the West End,” and it was rumored that he operated with a blade gripped between his teeth.
However, by the 20th century, operating theatres with audiences had all but disappeared.
Once anesthesia started being used, doctors no longer had to rush through operations as fast as possible, and the dramatic atmosphere faded. Doctors also began to realize that big crowds were bringing germs with them which was not so ideal for the patients.

Today, the setting is different, but the curiosity is still there.
People visit museums to see preserved specimens or detailed wax models showing diseases and injuries.
They scroll through online archives of historical medical photos, follow pages dedicated to unusual cases, or watch doctors explain procedures online.
A recent survey found that 58.5% of US adults used the internet to look for health or medical information.
In another survey of medical students, 39.2% said they watch cadaver dissection videos, while 85% said they use YouTube to study human anatomy.
It’s easy to understand why medical students end up watching anatomy videos or surgical clips online. But that still makes us wonder why people with zero medical background scroll through unusual medical photos, especially when they are not suffering from any illnesses.
Part of it is simple curiosity. The human body can do some pretty strange things, and people want to know what’s possible.
Sometimes, it’s also about awareness — seeing a rare condition online might help someone recognize it later in real life.
Take something like a green hairy tongue. It sounds made up, but it’s a real condition often linked to things like antibiotic use or smoking.
Then there’s anonychia, a rare condition where someone is born without fingernails. It doesn’t affect many people, but when it does, it can change both appearance and everyday function.
Stories and images like these are exactly why people keep scrolling.
Some are fascinating, some are a little gross… but they all show just how strange and unpredictable the human body can be.

Science actually has a pretty simple explanation about why some people are so drawn to things that should normally make them look away.
Our brains to tend to lock onto things that seem unpleasant or risky, and that’s why gross or disturbing things grab attention much faster than neutral ones.
This feeling likely comes from evolution.
Our ancestors developed a natural tendency to notice disgusting things because it helped them avoid danger such as spoiled food, or diseases.
Even though disgust feels unpleasant, it also forces us to pay closer attention.

But people don’t just notice, they sometimes also enjoy looking at gross and scary things.
Psychologists link this to something called “benign masochism.” It’s the idea that people sometimes like experiences that feel a little negative, as long as they know they’re safe.
For example, riding a roller coaster, watching a scary movie, or eating extremely spicy food.
“It seems possible that any negative feeling has the potential to be enjoyable when it is stripped of the belief that what is happening is actually bad, leaving behind physiological arousal that is, in itself, exhilarating or interesting,” writes Psychologist Nina Strohminger.
