Worst Advice for the Preservation of Health

From a book written in 1858:

Of course this advice is mostly wrong but some is surprisingly accurate.

“Rules for the preservation of health: Pure atmospheric air is composed of nitrogen, oxygen, and a very small proportion of carbonic acid gas. Air once breathed has lost the chief part of its oxygen, and acquired a proportionate increase of carbonic acid gas. Therefore, health requires that we breath the same air once only.

The solid part of our bodies are continually wasting, and requires Continue reading Worst Advice for the Preservation of Health

Worst Bicycling Experience

Some will tell you the worst thing that can happen while riding your bike is being chased by a dog. If that happens, here’s what to do:

1. Slow down or stop. There’s no fun for the dog in chasing something that isn’t moving.

2. In a deep voice, firmly order the dog to “go home.” They often will, but in any case, you’re making it clear who’s in charge and that you do not approve of their current behavior.

3. Get off the bike and place it between you and the dog. It’s a fence to protect you, and if necessary, you can press it against the dog in self-defense.

4. Yell for help. The owner will most likely take control as soon as your plight is discovered.

5. If you encounter the same dog frequently, contact your local animal control agency. In most neighborhoods, it’s illegal to let dogs run loose and bother people.

Worst Household Shedding

Humans shed a lot of skin, roughly 30,000 to 40,000 cells per minute.

Studies show that skin cells make up about 20% to 50% of household dust. The percentage can spike higher in specific localized spots (like inside mattress covers or on worn couches). The remaining majority of household dust is a mixture of outdoor and indoor debris, including:

Outdoor material: Soil minerals, sand, plant pollen, and outdoor pollution tracked in on shoes or blown in through windows.

Fibers: Clothing, carpet, furniture, and paper fibers.

Organic debris: Pet dander, insect parts, hair, and dust mite droppings.

Trace particles: Cooking soot and even microscopic space dust (micrometeorites).

Shown above: Close view of skin of hand.

Worst Dog Breeding

Many breeds of dogs are the result of human intervention. By selective breeding, the dogs have been made cuter. Very little dogs and pug-nosed dogs may have been bred too far into their specialty. The problem is with their teeth. It seems that their teeth have not decreased in size as much as their mouths, and when these teeth grow in, they come in all crooked. These crooked teeth trap food particles and eventually cause extreme decay and periodontal disease.

You can actually brush a dog’s teeth, and should, to help spare them the pain of mouth problems. To do it, start when the dog is quite young, and put your finger in their mouths and rub their teeth while playing with them. They will get used to this, and you can eventually substitute a toothbrush for your fingers. Don’t use human toothpaste, which is designed to be spit out. Use a small amount of baking soda.

Worst Thing About Pit Bulls

Pit Bulls, the breed of dogs which are mostly lovey, even-tempered pets, are sometimes bred to be vicious. Because of these rare badly-trained dogs, all pit bulls may be outlawed in England, meaning all of them in that country could be sentenced to death. There are 5,256,000 pitbulls in the United States, and approximately 9 million in England.

More about Pit Bulls

“Pit Bull” Isn’t Actually a Single Breed
The term “pit bull” is an umbrella label used to describe several distinct, distinctively built breeds descending from bulldogs and terriers. This category primarily includes the American Pit Bull Terrier, the American Staffordshire Terrier, the Staffordshire Bull Terrier, and the American Bully.
They Once Earned the Title of “Nanny Dogs”
In the early 20th century, pit bulls were widely celebrated in popular culture for their gentle, protective nature around children. Their patience and affection earned them a reputation as family guardians, leading to the affectionate nickname “Nanny Dog.”
They Were America’s Military & Cultural Mascots
During World War I and World War II, pit bulls represented American bravery, loyalty, and determination on recruitment posters and wartime campaigns. Their likeness was regularly used to embody national strength and patriotic duty.
Sergeant Stubby Was a Highly Decorated WWI War Hero
Sergeant Stubby, a pit bull mix, served on the Western Front during World War I. He survived being wounded, alerted troops to incoming mustard gas attacks, located injured soldiers in no-man’s-land, and caught a enemy spy, earning official promotion to Sergeant and national fame.
The “Locking Jaw” Myth Is Completely False
A persistent urban legend claims pit bulls possess a special physical locking mechanism in their jaws. Studies by veterinary anatomists have proven that their jaw structure is identical to that of any other dog breed; they simply possess strong jaw muscles, as do many large working dogs.
They Excel in Temperament Testing
In evaluations conducted by the American Temperament Test Society (ATTS), pit bull breeds consistently score higher than many popular family breeds, including Golden Retrievers and Chihuahuas. American Pit Bull Terriers frequently achieve pass rates near 87%.
A Pit Bull Was One of Early Hollywood’s Biggest Stars
Petey the Pup from the famous 1920s and 30s short comedy series Our Gang (later known as The Little Rascals) was an American Pit Bull Terrier named Pal the Wonder Dog, famous for the natural ring marking around his eye.
They Were the First Dog to Cross America by Automobile
In 1903, a pit bull named Bud accompanied Dr. Horatio Nelson Jackson and Sewall K. Crocker on the first successful transcontinental trip across the United States in a motor car. Bud wore custom goggles to protect his eyes from dust along the unpaved roads.
They Don’t Have a Naturally Aggressive Disposition Toward Humans
Historically bred to work closely alongside human handlers, pit bulls were selectively bred to be exceptionally friendly and submissive toward people, making human aggression an unnatural trait in properly socialized dogs of the breed line.
They Excel as Search and Rescue & Therapy Dogs
Due to their high athletic drive, intelligence, resilience, and affection for humans, many pit bulls excel as working dogs in law enforcement detection, search-and-rescue teams, and certified hospital therapy programs.

What Disgusts Cats?

You would think that animals have no sense of disgust if you watch a cat who will sniff practically anything. But they can be disgusted. To prove it, peel an orange a few feet away from your kitty-cat and you’ll see what I mean. The cat will wrinkle its nose and leave the area, possibly displaying even more obvious signs of disgust in the process.

Worst Aphrodisiac

An aphrodisiac is a substance such as a food, drink, drug, or potion that increases sexual desire, attraction, pleasure, or performance.

There was a time and place where plain old potatoes fetched over $1,000 per pound. Until the mid 16th century, Spaniards had never seen potatoes and for a while it was assumed that they had aphrodisiac qualities.

10 Interesting Facts About Aphrodisiacs

The word comes from the Greek goddess of love
The term “aphrodisiac” is derived from Aphrodite, the ancient Greek goddess of love, beauty, passion, and procreation.
The “placebo effect” is their strongest feature
Modern science shows that most historical and popular aphrodisiacs have little to no measurable physiological impact on human libido. Instead, their perceived effectiveness is heavily driven by the psychological placebo effect—believing something will work often makes it work.
Sympathetic magic drove ancient choices
Throughout history, many foods were labeled as aphrodisiacs simply because of their physical appearance. Known as the “Doctrine of Signatures,” ancient cultures believed that foods resembling human reproductive organs—such as figs, avocados, oysters, and rhinoceros horns—possessed magical properties to boost fertility and drive.
Oysters earned their reputation through zinc and history
Giacomo Casanova famously ate 50 oysters every morning for breakfast to maintain his stamina. While the claim may be embellished, oysters are exceptionally high in zinc, a mineral vital for testosterone production and sperm health.
Chocolate contains mood-boosting chemical compounds
Dark chocolate contains phenylethylamine (often called the “love chemical”), which releases endorphins and dopamine in the brain, as well as tryptophan, a precursor to serotonin. While the concentrations are too small to act as a direct physiological aphrodisiac, it undoubtedly elevates mood.
“Mad Honey” was used as a risky physical stimulant
In parts of Turkey and Nepal, bees collect nectar from specific rhododendron species, producing a rare honey containing grayanotoxins. In tiny doses, “mad honey” produces a mild euphoric sensation and vasodilation historically used to boost performance, though slightly higher doses cause severe toxicity, hallucinations, and cardiac issues.
Spanish Fly is actually a toxic, dangerous beetle
Historically famous as a potent aphrodisiac, “Spanish Fly” is crushed beetle tissue containing cantharidin. Rather than increasing genuine desire, cantharidin irritates the urinary tract and genital tissue, causing swelling and inflammation. It is highly toxic, causing severe kidney damage and potential death.
Nutmeg was once a prized, hallucinogenic love potion
In medieval Europe and traditional Ayurveda, nutmeg was considered a powerful aphrodisiac. In large doses, nutmeg contains myristicin, a compound that acts as a psychoactive substance, causing warmth, euphoria, and mild hallucinations—though, like Spanish Fly, large doses carry severe toxic side effects.
Chili peppers trigger a physiological mimicry of arousal
Capsaicin, the compound that makes chili peppers spicy, increases heart rate, stimulates nerve endings, causes sweating, and releases endorphins. These physiological reactions closely mirror the body’s natural response to sexual arousal.
Modern medicine recognizes only a few true performance enhancers
While true aphrodisiacs (substances that inherently generate sexual desire) remain largely elusive in pharmacology, modern medicine has successfully created erectile dysfunction treatments (like sildenafil/Viagra) which work on blood circulation, rather than altering mental libido directly.

Worst Reproduction Rate

A mouse can have eight babies. Assuming four of them are female, and knowing that a mouse can give birth 60 days after being born itself, after 18 months, a pair of mice can become 4.5 million.

10 More Facts About Mice

Extraordinary jumpers and climbers:
Despite their tiny size, mice can jump up to 18 inches (45 cm) into the air. They are also skilled climbers and capable swimmers.
They sing ultrasonic love songs:
Male mice sing complex, ultrasonic courtship songs to attract females. These sounds are at a pitch far too high for human ears to hear.
Whiskers act like radar:
Mice have poor eyesight and rely heavily on their whiskers (vibrissae) to feel surface textures, gauge distance, and navigate in total darkness.
Constant tooth growth:
A mouse’s incisors never stop growing. They grow at a rate of roughly 0.3 millimeters per day, forcing mice to constantly gnaw on materials like wood and wire to keep them worn down.
Extreme flexibility:
Mice can squeeze through tiny gaps as small as a pencil (about 1/4 inch or 6 millimeters in diameter) because their ribs are flexible and can collapse slightly.
Hyperactive hearts:
A mouse’s heart beats incredibly fast—ranging between 300 to 800 beats per minute, compared to a human’s average resting heart rate of 60 to 100 beats per minute.
Resourceful tail use:
A mouse uses its tail not just for balance while running along thin ropes or ledges, but also to help regulate its overall body temperature.
Mice are clean freaks:
Contrary to popular belief, mice are very tidy animals. They organize their nests into distinct areas for sleeping, storing food, and going to the bathroom.
Expressive facial features:
Research shows that mice use facial expressions to communicate emotions, including discomfort and pain, by flattening their ears, narrowing their eyes, and puffing their cheeks.

Worst Freedom You Can Give a Cat

The average life of an indoor cat is 17 years. The average life of a cat that lives outdoors is 2 years.

More Cat Facts

Cats sleep for most of their lives:
On average, cats spend around 70% of their lives sleeping, which equates to roughly 13 to 16 hours a day.
Meowing is mostly reserved for humans:
Adult cats rarely meow at other cats. They primarily use meowing as a way to communicate, request food, or seek attention from human beings.
Their whiskers are highly sensitive sensors:
A cat’s whiskers are not just hair; they are deeply rooted and packed with nerve endings. They help cats navigate in the dark and determine if they can fit through tight spaces.
A unique nose print:
Just like human fingerprints are completely unique, every cat’s nose print has a unique pattern of ridges and bumps.
Incredible jumping ability:
An average healthy adult cat can jump up to six times its own body length in a single bound. Humans, by comparison, can rarely achieve even half their body length.
They have a “third eyelid”:
Cats possess a third eyelid called the nictitating membrane. It acts as a protective shield and helps keep their eyes moist.
Cats are lactose intolerant:
Despite the popular trope of cats drinking milk from a saucer, most adult cats lose the enzyme needed to digest lactose after weaning, meaning cow’s milk can upset their stomachs.
Purring has healing properties:
Cats purr at a frequency between 20 and 140 Hz. Studies suggest that sound vibrations within this range can help lower stress, promote bone density, and heal soft tissue.
They walk like camels and giraffes:
Cats are “direct register” walkers, meaning they step with both right feet first, followed by both left feet. Camels and giraffes are the only other animals that walk this way.

Why Cats Walk This Way

Quiet movement: By placing their back paws where their front paws just stepped, cats make very little noise. This helps them sneak up on prey.

Safety: The front paw tests the ground first. When the back paw steps in the same spot, the cat already knows the ground is safe and stable.

Fewer tracks: It leaves fewer footprints in mud or snow, making it harder for other animals to track them.

Most Repulsive Bird

The turkey vulture is a bird that repels threatening animals in a unique way. The bird throws up in the enemy’s face. Its primary defense mechanism is projectile vomiting.

Why It Works

Foul Odor & Acid: Because turkey vultures feed on carrion (decaying meat), their stomach contents smell exceptionally foul. Additionally, their stomach acid is extremely strong and corrosive—enough to burn the eyes and face of an attacking predator.

Distance: They can shoot their vomit up to 10 feet (3 meters) away, aiming directly at the aggressor.

Escape Weight: Vomiting serves a dual purpose. Clearing their heavy stomach allows the vulture to lighten its weight quickly so it can take off into the air and escape faster.
