Some of the Most Incredible Facts About the Human Body



That’s right; most of you isn’t even really you. In fact, between 2 and 6 pounds of your weight is actually just bacteria. Feel free to factor that in next time you’re on a diet.

Scientists have discovered that there are small deposits of magnetite in human brains. While they’re not 100% sure why, a leading theory is that the magnetic crystals aid our sense of direction by drawing upon Earth’s natural magnetic fields. Similar deposits can be found in the brains of homing pigeons, dolphins and bats, who all use magnetic fields to navigate.

The muscle that moves your jaw up and down (called the masseter) exerts more pressure than any other muscle in your body — up to 200 psi on your molars! However, we still wouldn’t recommend trying to chomp through a jawbreaker.

You might not be able to run faster, but you can run farther! Human bodies are perfectly engineered for running long distances, and it’s believed we evolved this way in order to hunt more efficiently. In fact, this type of hunting — called Persistence Hunting — is still practiced by hunter-gatherers in Southern Africa. You can see a video of the process here.

There are a few other primates who can toss objects, but humans are the only animals who excel at accurate, high-momentum throwing. Some scientists argue that our ability to throw is very much responsible for our success as a species, as it gave us a way to kill strong animals from a distance. Today it comes in handy as a way to play fetch with your dog.

That’s right, GOLD! However, it’s only 0.2 milligrams of gold, which by today’s standards will net you…less than a cent. But still. It’s real gold. In fact, there are a lot of valuable chemical elements floating around your body, including Rubidium, Boron and Scandium (all valued at thousands of dollars per kilogram). All together, the chemical elements of an average human body are worth about $160.

Of course you know that your fingerprints are unique but, as it turns out, the shape of your ears is, too! Biometrics developers are working on ways of implementing this knowledge in order to easily identify individual people in crowds from CCTV footage or to take attendance in a classroom. If you’re looking for a way to evade this new technology, we recommend wearing a hat, or maybe investing in some Spock ears.

Both the shape and the pattern of bumps on your tongue are entirely unique to each individual. In fact, both your teeth and the bacteria in your mouth are also unique between people — even identical twins! So the next time someone calls you unoriginal, just stick your tongue out at them and show ’em how special you are!

A baby has over 300 bones at birth, but adults have only 206. So what gives? Did you just lose some bones and not realize it? Nope! Actually, many of the bones in a baby’s body fuse together to create bigger, mega-bones (not a medical term), and that’s how you end up with only 206 in adulthood.

Babies are born exhibiting a number of fascinating reflexes, including the ability to walk on a flat surface (as long as the baby’s body and head are supported). Another baby superpower is called the Palmar Grasp, which allows the baby to grab onto an object with surprising strength. In fact, some babies can even support their own weight (although we don’t advise trying to recreate the picture above).

And speaking of superpowers, here’s a shout out to your liver, which is basically the superhero organ of the human body. Your liver performs over 500 functions, including producing bile and cholesterol, removing bacteria from the bloodstream and — of course — clearing the blood of toxins from drugs and alcohol. Keep that in mind next time you complain about working overtime.


And if that’s not impressive enough for you, it’s recently been discovered that your nose can smell at least 1 trillion scents, making it the most sensitive organ in the body by a large margin. However, I think we can all agree that there are some scents you might be better off forgetting.

It’s called the Mammalian Diving Reflex, and it is seriously one of the coolest things your body is capable of. When you splash cold water on your face, your body thinks it’s going for a swim, and prepares accordingly. First, your heart rate slows down 10-25%. Then the blood vessels in your extremities constrict and send more blood to your lungs. As a result, you use up less oxygen and — if you were swimming — would be able to stay underwater longer.

Maybe the Mammalian Diving Reflex is what the people in face wash commercials are actually demonstrating…

Ounce for ounce, human bones can withstand a lot more pressure than steel. In fact, a cubic inch of human bone could bear a load of 19,000 pounds! Bones are also a lot lighter, less dense and more flexible than steel, which makes them a great material for, you know, supporting your entire body. Steel wins when it comes to building materials, though, because using bones would be a little too spooky.

Like, a lot of saliva. In fact, throughout the course of your lifetime, the amount of saliva you produce could fill the Olympic-size swimming pool pictured above…twice. Maybe even more if you spend a lot of time thinking about Warhead candies.

A single strand of hair can support about 100g (which is equal to about two candy bars). But twisted together, one person’s entire head of hair (consisting of about 150,000 individual strands) could support 12 tons of weight — that’s the weight of 2 elephants!

Not only is hair very strong, it’s also virtually indestructible. Aside from being flammable, hair won’t break due to extreme temperatures, and it’s also resistant to a lot of acids and other corrosive chemicals.

Although hair doesn’t easily break, you still lose between 60 and 100 strands of it every day. Think of how many elephants you could be lifting if you didn’t!

This reflex, known as the Photic Sneeze Reflex, is present in 18-35% of the population, and it causes people to sneeze when exposed to a change in light intensity (such as leaving a dimly lit building on a sunny day). Sneezing can also occur in some people after eating spicy foods, or even when they’re full after eating. This phenomenon is not completely understood, but we’re pretty sure it’s the lamest superpower ever.

While your eyes remain the same size throughout your entire life, your ears and nose will continue growing as you get older. This is partially due to the fact that they are made out of cartilage (rather than bone), but is mostly as a result of gravity. So they’re not actually growing as much as sagging. Regardless, you’ll be able to tell your grandkids “all the better to hear you with,” so that’s pretty cool.

Since fat is essentially an endocrine organ, it needs a supply of blood to function. So, as fat is added to your body, your body in turn constructs blood vessels and capillaries to provide blood to the fat cells. For each pound of fat, your body creates 7 miles of blood vessels, and that means your heart has to work harder to pump blood throughout your body. This is part of the reason why obesity is often linked to heart disease, and is also part of the reason why we’re having a salad for lunch.

Monkey on my back

And now for one of our regular, semi-obligatory Meth-related questions. I get at least a half dozen of these questions a month. And each and every one of them breaks my heart. I know nothing about the fellow writing me; I don’t know where he lives or his age. I don’t suppose it really matters, does it?

I need some help and I hope you can point me in the right direction. I am recently divorced and trying to move on in life but I’m depressed all the time and also using meth a lot. I have tried to have different sexual partners since my divorce and every time I’m with someone new I can get a erection when we are messing around with no problem, but soon as its time for penetration I loose my erection I feel like I’m having anxiety issues and also I’m very nervous, and I’m not impotent so can it be the meth preventing me to keep it up, or do I need medication for my anxiety? How can I overcome this problem?

I’m certain I can point you in the right direction. Thanks for asking. Allow me to speak plainly. Quit the meth! Quitting won’t solve all your problems, but it is the first and most important step. And frankly, if you choose not to quit, all your other efforts to pull your life together are doomed.

MonkeyBackMeth is not a therapy for depression, nor is it gonna help you connect with a new partner. It most assuredly will not help your erection problems; in fact, it is the cause of your erection problems. But I’ll wager you know that already, huh?

You also have an underlying performance anxiety problem that needs to be addressed ASAP.

Find a competent sex therapist to help you. look to the directory of The American College of Sexology for someone near you. Or you can check out my Therapy Available page.

In the meantime, take a look at some of the stuff I’ve written and podcasts where I talk about meth. Use the pull-down CATEGORIES menu in the sidebar, to your right, and scroll down till you fine the SEX & SUBSTANCES category. It’s under that category that you will find the subcategory Crystal Meth.

You’ll also want to take a look at some of the stuff I’ve written and podcasts where I talk about performance anxiety. Again, use the pull-down CATEGORIES menu in the sidebar and scroll down till you fine the SEX THERAPY category. Under that category you will find the subcategory Performance Anxiety.

Here are examples of the stuff you’ll find.

On meth:

Name: Joey
Age: 22
Location: Southern Calif
Love doing tina with masturbation and watching really hot porn. Think this is just social fun?

Nope, I don’t Joey. Despite the prevalence of this dastardly drug, there is nothing fun about tina…crystal meth for those unfamiliar with the term “tina”. If you love doing tina for whatever reason, I’d wager you’re hooked on that shit.

Listen, I’m not prude when it comes to using some crystalmakesmesexy.jpgdrugs recreationally. But I think that we’d do well to stick to those drugs that are more natural. The less processing involved (and meth is the worst in that regard) and fewer added chemicals (OMG, the crap they put in crystal) the better, in my humble opinion.

Despite the admitted high ya get, recent research shows that long-term meth use destroys nerve cells in the brain that regulate dopamine, muscle movement, memory, and decision-making. This damage can be wide-spread and permanent.

Your body reacts to crystal meth the same way it reacts to danger. Crystal floods the body with adrenaline — the same hormone that prepares us for emergencies. Adrenaline gives a super-charge of strength and endurance so the body can deal with danger and injury. But artificially triggering this response over and over again will have serious consequences.

When you use crystal, your nervous system shifts into high gear. The brain floods your body with “danger” messages. Your body responds immediately to what it thinks is a threat. It prepares to fight or to run away. Common body responses to perceived danger include:

  • Pupils dilate to let in more light.
  • Hair stands on end (“getting goose bumps”).
  • Blood vessels just under the skin constrict.
  • Body temperature goes up

Regular, long-term crystal use will diminish sores of neurotransmitters. Episodes of paranoia and anxiety become more frequent and longer lasting. Blocked blood vessels within the brain can lead to increased chances of stroke.

Crystal fucks with your dopamine levels. Dopamine delivers a sense of reward and pleasure. It is also associated with body movement. Too little dopamine causes paralysis or a Parkinson’s-like tremors and rigidity. Too much dopamine and a person can become paranoid, hear voices and get twisted thoughts. Sound familiar?

Crystal fucks with your serotonin levels. Serotonin is involved in regulating sleep and sensory perception. It plays a role in moods and regulating body temperature. Serotonin is involved with many emotional disorders like schizophrenia, phobias, super-aggressive states and obsessive-compulsive behavior. Too much serotonin can make it difficult (or impossible) to have an orgasm. And of course there’s the dreaded “crystal dick”…the inability to get it up.

Joey, listen up! You’re way too young with too much of your life ahead of you to self-inflict so much serious irreparable damage on yourself. If this weren’t such a troublesome drug, there wouldn’t be such a virulent anti and reformed tweeker community out there. Want to know the real truth about “tina” check in at: You’ll be glad you did.

On Performance Anxiety:

I get a dozen or so messages a month on this topic. I’ve written about it in numerous postings and spoken about it in several podcasts, but still the email comes.

One of the real bugaboos for anyone, regardless of gender, is living up to our own expectations of sexual performance. So many things can get in the way, literally and figuratively, of fully enjoying ourselves and/or pleasuring our partners.

The arousal stage of our sexual response cycle is particularly vulnerable to a disruption. And when there’s trouble there, there’s no hiding it. A limp dick or a dry pussy can put the kibosh on all festivities that we may have hoped would follow.

However, performance anxiety can strike any of us, regardless of age, and at just about any point in our sexual response cycle. This is a particularly galling when it seems to come out of the blue. And regaining our composure can be more far more difficult than we imagine.

Today we will be focusing on male performance anxiety. I’ll address female performance anxiety at a later date.

You are what you eat

Name: Edie
Gender: female
Age: 52
Location: Galveston
Are there any foods I can add to my diet that might boost my sex drive? Some of which seems to have been lost in my advancing years. Any information would certainly be appreciated.

People first sought aphrodisiacs as a remedy for various sexual difficulties, especially performance anxiety. Aphrodisiacs are also thought to boost both male and female potency. In ancient times nutrition was always an issue. Food hasn’t always been as available as it is today. And of course, nothing pulls the plug on the libido like malnutrition. And hunger radically reduces fertility rates.

Our forbearers believed that anything in nature that looked like or represented fertility, such as bulbs, eggs, snails were considered to have sexual powers. Other types of foods were considered stimulating because they physically resembled male or female genitalia.

The Greeks and Romans believed aniseed had special powers. Sucking on the seeds is said to increases your desire. Or maybe it just freshened the breath enough to get close enough to fuck.

Almonds have been a symbol of fertility throughout the ages. The aroma is thought to induce passion in a female. Arugula or “rocket” has been considered an aphrodisiac since the first century A.D. Arugula was added to grated orchid bulbs and parsnips, which was combined with pine nuts and pistachios for a full-on erotic feast.

The Aztecs called the avocado tree the “testicle tree” for obvious reasons. The fruit hanging in pairs, as it does, resembles a man’s cajones.

Bananas have a marvelous phallic shape. But from a more practical standpoint bananas are rich in potassium and B vitamins, necessities for sex hormone production.

Chocolate is known as the “nourishment of the Gods”. Chocolate contains chemicals thought to effect neurotransmitters in the brain. It also contains more antioxidants than does red wine.

Carrots are believed to be a stimulant to the male. The phallic shape has long been associated with stimulation since ancient times. Early Middle Eastern potentates used carrots to aid in their seductions.

The Arabian nights tells a tale of a merchant who had been childless for 40 years but was cured by a concoction that included coriander. Cilantro is also known as an “appetite” stimulant.

Fennel, like anise, was found to be a source of natural plant estrogens. Use of fennel as an aphrodisiac dates back to the ancient Egyptians.

An open fig looks like a vagina. And traditionally it is thought of as sexual stimulant. A man breaking open a fig and eating it in front of his lover is a powerful erotic act.

The ‘heat’ in garlic is said to stir sexual desires. Garlic has been used for centuries to cure everything from the common cold to heart ailments.

Ginger root raw, cooked, pickled or crystallized is a powerful stimulant to the circulatory system. And what is good sex if it isn’t all about healthy blood flow?

The Egyptian believed that honey was a cure for sterility and impotence. Medieval seducers plied their partners with Mead, a fermented drink made from honey. Lovers on their “Honeymoon” drank mead and it was thought to “sweeten” the marriage.

Mustard, maybe because of its bite, is believed to stimulate the sex glands and increase desire.

Chinese women prize nutmeg as an aphrodisiac. In quantity nutmeg can have a hallucinogenic effect.

Oysters are legendary aphrodisiacs. They of course resemble a pussy, but they are also very nutritious and high in protein.

Tomatoes, known as the “love apple” are considered love food, because they have great nutritional value and their acidity is considered a sex stimulant.

The scent and flavor of vanilla is believed to increase lust.

Good luck

Tease and Tickle

Hey sex fans!

It’s not just a Friday; it’s a Product Review Friday. And today we bring you a review of another product that comes to us from our favorite retailer — Adult Sex Toys .com.

Here to tell us all about her new vibrator is Dr Dick Review Crew member, Jada.

Crystal Chic Wand — $36.45


You’ve probably noticed that the Dr Dick Review Crew has had a number of wand type massagers to review lately. All of them have been a variation on the granddaddy of wand massagers, the Hitachi. All have that distinctive bulbous head on a sturdy shaft. This classic wand shape is turned on its head with today’s offering, the Crystal Chic Wand.

There is nothing bulbous or bulky about this dandy. In fact, it is on the other end of that spectrum. It’s slim and sleek. It has comfortable to hold handle, a bendable shaft made up of gradually smaller beads and it’s topped of by a glorified bullet vibe. It’s 11.5” long, but only 7″ of that is the bendable beaded section. By the way, it’s just the tip of the Crystal Chic Wand that vibrates.

The three-speed controller, basically just a single button, is in the base of the handle. The handle is also studded with six crystals (rhinestones?). It’s also waterproof. The entire thing has a lovely velvety feel to it and it is easy to grip even with lubed fingers. It operates on one AA battery (not included).

I was completely under whelmed at first sight. The Crystal Chic Wand comes in a cheesy plastic package that is decidedly un-GREEN. I was all prepared to not like this thing, but I gave it a go anyhow. Sure glad I did, because I liked it immediately. Once out of its ugly packaging I discovered that the Crystal Chic Wand is really fun and versatile. I admit; my first impressions were totally wrong.

You can use the Crystal Chic Wand either internally or externally. I have a preference for external; it’s just the thing on my clit. I did try it as a G-spot vibe and that worked too. What’s great about it internally is that it’s not bulky, so you can pinpoint the vibration precisely where you want it. I tried to talk my husband into trying it as a prostate massager. The vibrating tip is no wider than my index finger. But he declined; he’s not ready for even a little butt play yet. That was disappointing, because I know he’d enjoy it. So you see what I mean when I called the Crystal Chic Wand versatile.

I want to call your attention to the bendable feature, because this was my favorite part. You can shape it however you want and it will hold that shape. BRILLIANT! The battery compartment in the handle is easy to open and close. Just remember to tighten it securely to keep the Crystal Chic Wand waterproof. I used the vibe for over 6 hours on just one battery, which is pretty amazing. If I have one complaint it’s that it’s not very quiet, particularly on the medium and high speeds.
