Mark Twain once said, “It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.”
Here are 60 pieces of false knowledge many people misquote as absolute facts.
- Shaving causes hair to grow back thicker. – Shaving does not cause hair to grow back thicker. This false knowledge carried by many people is due to the fact that hair wears down and appears thinner over time. Thus, new hair looks thinner than old hair and feels coarser due to unworn edges.
- We only use 10% of our brain. – We may only be using 10% of our total brain at any one given time, but this 10% is nearly 100% of the brain capacity designed to calculate the data sets we are currently working on. For example, the creative side of the brain isn’t going to help you remember a statistics formula. It wasn’t designed to do so and it will remain unused during this process.
- Rice is pure and healthy. – Actually, it’s often contaminated with small traces of arsenic.
- Milk is absolutely essential to your health. – It’s just one of numerous sources for calcium and Vitamin D.
- People should eat mostly carbohydrates. – After all, that’s what the food pyramid says, right? False! Look around at the average American’s midsection. An excessive intake of carbohydrates is fattening. Wholegrain foods containing fiber should be the primary source.
- Tar and nicotine in cigarettes cause cancer. – Nope, excessive smoke in your lungs causes cancer. In fact, the Radon and Polonium in the smoke is enough to account for most cases of cigarette related lung cancer.
- Being overworked can cause a nervous breakdown. – Actually, nervous breakdowns do not even appear as an official mental health disorder in DSM-IV.
- Depression is purely biochemical. – Depression is more closely related to a specific cognitive state of mind.
- Male masturbation is unhealthy. – I’m sure most teenage guys will love this. Research has shown that masturbating early and often may reduce Prostate Cancer later in life.
- Females are biologically inferior in math and spatial skills. – Statistically, males and females have very similar grade averages in math courses from grade school through doctorate level classes. Male enrollment, however, drastically out-numbers female enrollment.
- Based on global warming Earth will be hotter in 2000 years. – Nothing is certain. In this kind of complex nonlinear system, we could have an ice age.
- Corn based fuel (biodiesel) is better than gasoline. – It’s more expensive, increases the cost of food and still pollutes the environment.
- Religious faith alone heals. – This is only true on a physiological basis to a minuscule degree. Religious faith cannot replace medical intervention.
- Herbal medicine is healthier than modern medicine. – In numerous cases herbal medicine has been found to have either zero value or undesirable side effects.
- Chills don’t make you ill. – Wrong! Getting a chill in your body shocks your immune system, which prevents it from effectively keeping viruses at bay.
- Highly social people are psychologically healthier. – Not healthier, but usually a bit happier.
- Nutritional supplements make you live longer. – Quite often the opposite is true. Many people misuse supplements and end up doing more harm than good to their bodies.
- Hair and fingernails continue to grow after death. – Hair and fingernails do not grow at all after a person dies. This illusion is based on the fact that skin dries up and shrivels away from the foundation of hair roots and nails, making the hair and nails look longer than before death.
- String Theory – There has been zero proof that String Theory relates to the physical universe.
- The Big Bang was an explosion. – It was an expansion of space, not an explosion.
- Windows is easier to use than Linux. – Linux, harder? Only if you are completely against the notion of learning something new.
- A true free market exists. – Take a hard look at the price of oil and tell me that the recent 100% price spike is completely based around supply and demand and not partial price manipulation.
- Ozone is healthy. – Ozone is only healthy when used in controlled medical environments. Outside of that, it is harmful to the lungs if inhaled.
- Stretching before exercise is a sure thing. – Only if you stretch properly. Many people injure themselves due to improper stretching practices.
- Weight belts prevent injuries. – If used properly when lifting extreme amounts of weight, they do help. The problem is that most amateur weight lifters swing their bodies and hyper-extend their backs while lifting weight with their upper body. When they wear weight belts for upper body exercises they still swing their bodies and hyper-extend their backs, only this time they use more weight and the injuries are more severe.
- Soap kills germs. – Plain (non-antibacterial) hand soap does not kill germs. Instead, it lifts the germs off the surface of your skin, forcing them to be washed down the drain.
- Alcohol is a great antiseptic for open wounds. – Alcohol is a great disinfectant for intact skin and inanimate, non-living things. Alcohol is not effective or healthy when applied into open wounds. When used on open, exposed tissue, alcohol actually kills some of the human tissue along with the germs. This can drastically delay the healing of larger wounds.
- Coffee is unhealthy. – It’s all about moderation and timing. If you take excessive doses of coffee late in the day, you’ll be up all night, and that’s not healthy. However, coffee is also a great source of healthy antioxidants. Coffee consumption has been medically linked to the reduction of certain cancers and chronic diseases. There have even been controlled studies which have concluded that moderate doses of coffee can be a healthy energy booster for a person partaking is intense physical exercise.
- Fructose is healthier than Sucrose. – Sucrose (table sugar) is made from sugarcane. Fructose is usually made from corn (also found in fruits) and is a cheaper alternative to Sucrose. Once thought to be healthier, fructose actually has many negative downsides. Some of these downsides include cholesterol increases and digestion difficulty, in addition to the fact that it converts to fat more easily than other types of sugar.
- Exercise alone increases lifespan. – It increases the quality of your life and the ability of your body, but exercise alone has not been proven to increase lifespan. A regular habit of eating healthy food, however, will.
- Time heals all wounds. – Time does heal most psychological wounds, but if the wound is severe (e.g. someone killed your spouse) it may never fully heal.
- Eye exercises can improve vision. – Eye exercises for improving vision have never been scientifically proven to work. Results contain significant variance.
- Cheese is healthy. – Regular cheese contains an extremely high content of fat. As with anything, moderation is the key. In smaller doses it can be a decent source of calcium and protein.
- Tan people look good, so tanning in the sun is okay. – Extremely tan people have burnt skin. Check back with them at age 60 when they have skin cancer.
- Swimming in chlorine pools is healthy. – While the chlorine levels found in most swimming pools won’t noticeably hurt a swimmer, continuous exposure is unhealthy for the skin and the eyes. True saltwater pools are a much healthier alternative.
- Jogging along a traveled roadway is healthy. – Jogging along a traveled roadway forces the jogger to inhale large quantities of air polluted with car exhaust. Like secondhand smoke, this can be extremely bad for the health of a person’s lungs.
- Heading a soccer ball doesn’t hurt the player. – Soccer players don’t just head the ball; frequently their heads collide with another player’s head while trying to head the ball. In both cases there remains a potential for mild amounts of brain damage, especially when the heading is repeated over a long period of time.
- Free-diving doesn’t cause brain damage. – Do you really think it’s healthy for the human body to remain in deep water with no oxygen for extended periods of time? Based on the complications of pressure equalization and a lack of oxygen, free-diving will cause small amounts of neurological damage no matter how you breathe out while ascending.
- Brain scan imaging tells us lots about the mind. – Understanding the brain by looking at brain scan images is sort of like trying to evaluate a software-based computer problem by looking inside the computer case. You may locate the hard-drive, but you’ll never know exactly what’s on it. Brain scans are efficient at detecting gross physical abnormalities, which do save lives. However, much of the claims about reading a persons thoughts and future is complete nonsense. Brain scanning cannot even reliably detect early stage Alzheimer’s disease as of yet.
- Rorschach inkblot tests are reliable. – Various studies have depicted the conclusions found by inkblot test administrators as being akin to fortune teller cold readings. The controversy stems from several factors including the potential variance of interpretation, general verifiability and reliability, the inability to completely baseline testing norms and the limited number of psychological conditions the test is supposedly capable of determining.
- Positive thinking (and the placebo effect) helps heal cancer. – Medical treatment is the only way to eliminate cancer cells. Positive thinking does nothing more than help cancer patients mentally prepare for medical treatment.
- Eggs are unhealthy. – Eggs are a food you should eat regularly, but in moderation. They are a great source of essential nutrients and high in protein. Unfortunately, they also contain a high level of cholesterol, which means limiting intake to 1 or 2 eggs a day.
- Regular dentist visits create healthy teeth. – Dentists repair problems and make suggestions. Brushing your teeth twice a day and flossing will create healthy teeth.
- Poor people are lazy. – Money is not always the best measure of personal effort and drive. Remember, some millionaires are very poor and some people with small incomes are very rich… in happiness.
- Asians are smarter than Caucasians. – Asian grade schools are typically more disciplined and demanding than public school systems elsewhere (especially the USA). So while Asians do not dominate over Caucasians in intelligence, many of them come out of grade school with a much better education.
- You can drink as much water as you want. – It may sound weird, but people do die from fatal water overdoses. An overdose occurs when an overabundance of water in the body causes regular salt levels in the blood to become drastically diluted. This dilution can cause swelling in the brain and organs which may result in coma or death.
- Ivy League students get the best education. – Education is about self-discipline, curiosity and personal drive. Some of the most educated and successful people on this planet are self-educated. Strictly from a formal education standpoint, think about the fact that MIT (a top technical school) and Duke (a top medical school) are not Ivy League.
- Human growth hormone (HGH) increases life span. – In many cases the opposite is actually true. HGH does tend to improve the quality of life in a person’s elder years by reducing fat production in the body while increasing muscle mass. However, no critical factors for extending a person’s life span are affected, such as bone density improvements, cholesterol level reduction, lipid measurements, maximal oxygen consumption, or any other factor that would increase a body’s durability. Regular consumption of HGH has also been linked to various negative side effects such as joint swelling, joint pain, carpal tunnel syndrome and an amplified risk of diabetes.
- Shouting into a phone helps the other person hear you. – In most cases it will rattle your phone’s microphone and distort the sound of your voice, thus making it harder for the other person to comprehend your words.
- Tabasco sauce causes stomach cancer. – This is an urban legend. In reality, researchers have discovered that spicy pepper sauces may actually help fight the growth of cancer cells. The University Of Pittsburgh School Of Medicine found that capsaicin (the hot ingredient in pepper sauce) induces apoptosis in the cancer cells.
- Karate works better than dirty street fighting. – Sad, but true… The dirty street fighter with a concealed weapon will probably win the fight outside of a formal fighting ring.
- Expensive CD players produce better sound quality. – If you want better sound quality spend your money on a decent amplifier, equalizer and a high quality set of speakers. An expensive input device like a CD player is worthless if the other components are not in place.
- Monster Cables (expensive audio/video cables) are worth it. – In most cases you will hear and see no difference in the quality between a Monster Cable and a standard cable. The only exceptions occur in extremely high end systems where slight cable attenuation creates a noticeable difference in clarity.
- Lie detector (polygraph) tests are accurate. – The American Civil Liberties Union released a report in 1996 stating that “…there is no machine that can detect lies. The ‘lie detector‘ does not measure truth-telling; it measures changes in blood pressure, breath rate and perspiration rate, but those physiological changes can be triggered by a wide range of emotions.”
- Raw veggies are always healthier for you. – Cooking certain kinds of vegetables such as onions and garlic can actually increase the variety and potency of nutrients that get released inside a person’s digestive track. In addition, cooking vegetables also eliminates the potential for bacterial contamination such as salmonella.
- SUV’s are safer than regular cars. – When it comes to vehicles, bigger does not mean safer. Many SUV models are top heavy and have poor handling. Several recent accident-related death statistics have shown that fatality rates in SUV’s are no lower than those in standard size vehicles.
- Soft water is healthier than hard water. – Reverse it. Hard water is healthier than soft water. Hard water contains natural minerals and is sodium free. Soft water has sodium and is stripped of all natural minerals. So why do people soften water? Soft water has cleaning benefits. When soft water is used, soap lathers better and cleans objects more efficiently, kitchenware and shower glass will sparkle and remain scum-free and hair and skin will also feel smoother.
- Astrology has value. – Astrology is one of the world’s oldest con games. It’s complete rubbish. People want to believe that the future can be predicted, which is exactly why the traditions of Astrology still exist in modern cultures.
- Chiropractic therapy can cure various diseases. – Chiropractic therapy has been medically proven to help with some joint and bone related injuries, comparable to various forms of physical therapy. However, there is no medical proof to backup the popular assertions from chiropractors claiming that chiropractic therapy is an effective remedy for other diseases or conditions (such as chronic stress headaches).
- IQ is a perfect measure of intelligence. – IQ tests are only one of many imperfect techniques for measuring human intelligence. IQ tests don’t measure creativity, social skills, general wisdom, learned aptitude or an entire gamut of other traits most people would consider as a measurement of intelligence. IQ tests can be used as a measure of basic intellectual potential, but do not reflect accurate measurements in all circumstances.

I’m glad to hear about the coffee thing and the tabasco sauce. I should be in good shape! I was surprised that positive thinking didn’t help more than you indicate here in combating cancer. I always thought that positive thinking boosted your immune system or increased some chemical in the body that would help you stay healthier. Who knew?
John says
Number 18 is only true for high-frequency AC electricity, not DC. And for practical purposes, low-frequency AC power cables that operate at 60 Hz and flow through normal sized power cables also flow uniformly through the cables, for instance. DC electricity flows uniformly through the cross-section of a wire, whereas AC electricity, because of its fluctuating behavior, exhibits what is called the “skin effect” in electromagnetic theory; as the frequency of the AC electricity increases, it tends to flow on the outside of the conductor and not uniformly through the inside.
Marc says
@John:
You are correct. I had it written wrong and I replaced #18.

How about… Mammal blood is bright red or scarlet when oxygenated and a darker red when not oxygenated. It is never blue. Veins appear blue through the skin because of Rayleigh scattering, the same effect responsible for the blue sky.

P. Greek says
Re: #59 Chiropractic Therapy
I noticed that the neutrality of the Wikipedia article that was cited has been disputed. So, I’m not sure that there is enough evidence or “medical proof” to say true or false about that claim. Maybe this one should be taken off the list–for now.
Marc says
@Juliana:
Great addition! Thanks!
@Tom:
You’re right… not all lists are accurate. I didn’t write all these points (a guest blogger did), but I did edit them all. I had to work out some kinks, but I do believe each point holds a great deal of truth.
@P. Greek:
Penny’s point was not to state that #59 is false, but instead to point out that there is no medical proof to prove it.

It is amazing how often we accept things as truth based only on rumor or because we heard it once on TV! Great job exposing a lot of myths for what they really are. I love this kind of stuff!
Pratik Dwivedi says
Well, i agree with most of the above BUT not with what is said about Astrology.
Indian Vedic Astrology can really predict your future most of the times.
The incorrect predictions are more due to human error rather than a flaw in the vedic astrology principals/methods.
Thanks

I need to take the one about yelling into a cell phone to heart. Without even trying I get louder and louder on the phone. It’s a bad (and annoying) habit.
Fuzzles says
Some of these “facts” are subjective, and by passing them off as the real answers to false knowledge, you’re only perpetuating the same kind of behavior you seek to fight.
Marc says
@Fuzzles:
You’re right. A few of these points are subjective because they have not been scientifically proven one way or the other. The point for these is to first state the fact that the common misconception (i.e. false knowledge) is not true and then to state a counter argument.
Orchid says
So, by your own admission, this list is inaccurately title. It should be “common assertions which may or may not be true.”
This does sort of make it look like stridently claiming these things are false then admitting they aren’t proven false is adding to the sum total of inaccurate information. In essence, you’re saying, “I don’t believe these things, so you shouldn’t either.”
Also, frankly, saying there’s no proof that something is true isn’t the same as “it’s not true.” It’s simply saying it can’t be supported by facts at present (like the assertions of temperatures in the future).
Marc says
@Orchid:
You have to remember, this is a guest post. I did my best to verify the accuracy of each point. Most of these points are 100% accurate. However, a few are a bit subjective like #51 and #31, but still hold a great deal of truth and support.
Martin says
I loved the article, but I am curious of your sources, since you only write some sources in each “none-fact”.
Nice to keep in mind that education isn’t always proportional with knowledge. 🙂
Kay says
I agree many of the things on this list are subjective. Saying positive thinking doesn’t do anything to help fight cancer is pessimistic many people who gave up mentally probably wouldn’t have survived it.
penny says
All astrology is nonsense–because their is no scientific reason that the position of planets should have any effect on human destiny. To say otherwise is to have
a primitive mystical view of the world–like believing in tooth fairies.
As Carl Sagan was found of saying: ” The gravitational pull of Mars on a baby is less than that of the obstetrician!” There is no other possible physical effect that the planets could have on you–unless you believe in magic.
There have been studies to see if “positive thinking” has any effect on cancer survival rates. And, the answer is NONE. It’s science, and if that’s pessimistic, well so be it.
There is statistical proof that chiropractic treatment doesn’t help medical illness except for bone and joint pain–which also makes scientific sense since the theoretical basis of chiropractic is scientific nonsense.
As to “time doesn’t heal all psychological wounds”:
Scientific studies on trauma have shown in animal
models and human brain scans that trauma induces changes in brain structure. Some of it may be reversible, but not all. There is good evidence that it is due to poisoning by Stress hormones.
Clinical evidence shows that PTSD can persist–especially without treatment–for an entire lifetime. This was also shown in dogs, as far back as Pavlov.
( For electromagnetics junkies):
Finally, yes, there is a skin effect–that is why
submarines use low frequency radio.
They are in a half space ( to first order), and the field is periodic–not DC.
A proper math analysis in the case of a wire and DC is complicated. For an infinite straight wire, it is easy–use fourier decomposition, the
Helmholz equation,
then Bessel expansions–IF it were true that the speed of light were the same in and out of the wire–which it is NOT. Thus, this proof ( That there is NO skin effect for a wire in the periodic field case)–at Wikipeda
is false. But, it should be doable by a smart masters student in math, and is probably somewhere in the literature. One then needs to do the DC case by Fourier decomposition.
And, anyway, a real circuit is not an infinite wire but a kind of topological torus–and with the proper boundary condition for Maxwell’s equations ( recall the different speeds of light in an out of the wire) it would be fun ( and nontrivial to analyse
properly). Sort of a Cambridge Math Tripos question of the old school.
If I had several days to waste, I would do it myself.
So, the correct answer would be–I am not really sure.
Thanks for pointing out the skin effect as relevant.
I had made the mistake (interesting for psychological reasons related to the title) of accepting the argument for no internal field in the DC case, given
in Vol II of the Feynman lectures on physics–where he shows that the Poyntng Vector is zero inside the wire. ( look up Poyntng vector in the index). He then states that in the DC case the energy is all outside the wire.
He made a subtle error–and this is in many books on the field. Anyone here know what it was? Fun!!
Feynman won a Noble Prize for coinventing Quantum Electrodynamics. But ANYONE can make an error.
MY error was to not think about his proof carefully
, in all the years since I read it.
penny says
One wonders about Homopathy–because the standard argument is that the dilution is so great that no effect could occur. But, if one is allergic to something, only a few molecules can cause a severe reaction. It is interesting that–as far as I know–no one has made this connection.
Many of the facts taught in school when I was a child in the 1950’s are now known to be false. Anyone remember the twilight zone on Mercury? ( The reason for the name of the TV series was this fact.)
Anyone recall that bad mothering caused Schizophrenia, Autism, Homosexuality etc. ,? How about: watching TV would destroy your eyes? Or:
Coffee would stunt your growth. Or: IQ can’t go up?
Or: Eye Exercises? Or, Eat Spinach like Popeye for iron ( it is mostly not bioavailable).
Another one: Airplanes fly because of the Bernoulli
effect–faster air on top has lower pressure.
ImReallyAnElf says
I can’t help but sigh when people say things like Penny just did:
“All astrology is nonsense–because their is no scientific reason that the position of planets should have any effect on human destiny. ”
The only certain nonsense is that some humans are so all-fired arrogant that they believe if they can’t demonstrate it, it can’t exist.
penny says
Elf, it is NOT arrogance—it is the scientific method.
If one doesn’t use the scientific method, then the world is based on MAGIC. Believing in magic, without proof
is arrogant.
IT isn’t that I can’t demonstrate that astrology works–it is that statistical analysis shows that it
it doesn’t, and that there is NO scientific reason that it should work. Astrology is nonsense–that is the conclusion of science–and that means not just me
but all SCIENCE.
Again, the planets are balls of ROCK–they move under the influence of gravity, and there is no possible
scientific mechanism that could cause the position of the planets at your birth to affect your destiny.
Astrology is a relic of the prescientific mind set–when people thought the planets were gods.
That is why Mars and Venus etc., were thought to affect destiny.
Why not read Carl Sagan on the subject?
If you like, there is a nice blog called “bad astronomy”
and believers in astrology can discuss it with the astronomers there. Be prepared, because astronomers know that astrology is no different from believing in
magic unicorn dust.

actually. regular soap does kill germs. It breaks through the fatty membrane of the bacteria cell and thus kills it.

Yes, but not very well. Many germs survive quite well in regular soap. That is why chemical disinfectants are used at hospital and in
surgury hand prep.

I agree on every single point except the Linux thing and this is the only point where you sound emotionally motivated.
Maybe you are right if you reduce it to the OS itself but not to the real workflow you have to master when it comes to make your devices work find the drivers or work with others.
I’ve tried XP Vista several Linux derivates and OSX and nothing beats the simplicity of OSX.
sir jorge says
Most of this list is just common sense.
Wade says
“Nervous Breakdown” is also know as an anxiety attack which is a sudden and severe manifestation of an anxiety disorder many of which are noted in the DSM, and the etiology of some can be partially stress… say from being overworked.

I haven’t tried OSX yet.
But, I like linux a lot better than I like Windows.
I started when I wanted to do Latex ( a math markup
language) and I found out that the Windows version worked poorly and had to be expensively updated.
However, Fedora Linux had an included free version that worked very well using vim–a unix editor.
Later, I also added Ubuntu–which, once I found out how to run webvideo and audio on–works very well for most things–it is running faster than Windows did and with far fewer problems–n0 adware to remove or check, for example.
All my devices work just fine with Linux–perhaps because I use an older computer at home, and the
device drivers are now standard.
All the software for Linux that I ever need is free. That is very helpful to me. Unix is very powerful and with a few simple command line operations I can do amazing things.
Simplicity is not that important to me. What is important is working well, stability, and power.
And learning Unix wasn’t all that hard anyway.
It’s very logical.
I will never use Windows again–it is bloated, runs poorly, needs updates that cost money, software is expensive, and it need virus checkers, adware checkers etc. It isn’t very powerful either.
The Mac system is now built over Unix. I upset the guys at the Apple store when I asked for a free demo
of Leopard. They showed me all these silly bells and whistles and I finally just said: ” How do you bring up the unix terminal?” ” That is enough for me.”
( I had no intention of buying a MAC–my seven year old computer works just fine for me–when I use Linux.)
In short, I am very happy with my two flavors of Linux.
drip says
yeah i think positive thinking does boost up your immune system which helps in eliminating the growth of cancer cells which only grows if your immune system is low..
and Unix systems are simple but you need to be intelligent enough to understand its simplicity..got that qoute from the web..=p
drip says
by the way…thanks for the post…its great…=)
penny says
Wade,
Good suggestion, but I don’t accept it, unless you redefine terms. Here is why.
Nervous breakdown was
, historically, a complete physical and emotional collapse–brought on by stress. It was treated by months of rest and then people returned to health, without other treatment. There was no stigma
for it, at the time, by the way.
It was associated with a certain physical type –thin,
and ectomorphic ( which–see below–would be also a result of too much cocaine!) Such people were called Neuroasthenic.
We just don’t see that anymore–if indeed it ever existed. But, this may be because we have antianxiety drugs.
The DSM does list anxiety disorders and it is certain that if nervous breakdown existed it would be listed in that classification–but it isn’t there.
My theory is that there never was such an illness as nervous breakdown, but that there was unrecognised “bipolar” disorder–which led to extreme overwork–and then depressive collapse in a cyclical fashion.
One certainly sees a lot of historical accounts of successful scientists that involve successive “nervous breakdowns”. These date from the 19th and early 20th century. When re-reading E.T. Bell’s “Men of Mathematics”, I was struck by how common this was–and how when I read these accounts recently, it screamed “bipolar disorder” to me.
There was also a lot of abuse of stimulant drugs–such as cocaine–which was legal in the 19th century.
There is no evidence either, that
overwork stress leads to “acute anxiety syndrome”–in fact, it is believed to arise from underlying
emotional issues–often from childhood or social relations.
This reflects clinical practice–and may be just another false belief of
psychotherapists.
Moreover “acute anxiety syndrome” requires treatment not just rest.
Pavlov did show that dogs could be
conditioned into ” stress collapse” but not by overwork–by being pushed into double binds under torture conditions.
So perhaps, if one is being TORTURED at work ( by abuse) with double bind situations, one might have some sort of collapse–but overwork alone doesn’t seem to be enough. And, even the above is conjecture–for it isn’t in the DSM–and we are not dogs.
Soldiers do show “battle fatigue”
–once known as shell shock–and this is in the DSM, as form of postraumatic stress disorder. But, conditions of battle ( involving horrendous
scenes of dismemberment etc.) are not the usual conditions of “overwork”.
So, I guess I don’t accept your hypothesis. Still, it was a very interesting idea.
Of course, you don’t have to accept my statement either.
It is the discussion that is important. Rather than accepting things blindly–one must think and discuss them.
Thanks for making me think!!
penny says
Jens,
Ok, I played around more with OSX at my friend’s place, and I still agree with my initial impression of OSX
( which is Leopard) from the Apple store demo.
It’s great if what one wants is a windows like system that has a lot of glitzy eyecandy and can do simple things with a minimum of user learning.
But, I much prefer the power of straight unix–just give me the unix terminal.
I don’t like eyecandy and chatty programs. I like command line, control and power.
And free is great too. Apple computers are very expensive–run the same chips as cheaper computers, and one pays a premium for the Leopard glitz.
By the way, if one does like OSX Leopard, it has been implemented as a free linux based imitation.
After all, OSX is based on Unix.
This was available with days of the release of Leopard.
Most of the Linux-unix community couldn’t care less.
In fact, I almost never use the windows imitation “Graphical inteface” in Linux–I find it slow and silly. I just run Linux as unix, from the command line. Less than ten simple commands do all the “graphical” stuff, and better.
I think putting the “Graphical Inteface” in Linux was an error–more useless bloat.
Unix is not supposed to be windows.
Omar says
This is true to some point, Alcohol is a BACTERIOSTATIC which means that fixes germs and bacteria so it doenst replicate or reproduce but doesn’t kill it. If u want to kill germs and bacteria you need a bactericide like iodine, which is safer on any tissue.
Ben says
Unfortunately, two of these I highly believe are wrong.
“Fructose is healthier than Sucrose”
“Fructose” is simply the natural sugar inside of fruits and vegetables, and fructose is much healthier then table sugar, yet the side effects come from people who might eat excess fructose, excess amounts of fructose also causes weight gain, and with the amount of foods on the market with “High Fructose Corn Syrup” I believe it might be to blame, yet if you are simply eating fruit, you will not have a problem like that.
“Positive thinking (and the placebo effect) helps heal cancer. – Medical treatment is the only way to eliminate cancer cells. Positive thinking does nothing more than help cancer patients mentally prepare for medical treatment. ”
Medical treatment, is not the only way to kill cancer cells, and positive thinking does deeply effect the growth of cancer, stress has a huge impact on the immune system, and when your immune system is weakened, your body cannot fight the cancer cells as efficiently. Despite many believes, your bodies immune system, can fight and kill cancer cells, and you can cure your cancer with a healthy lifestyle and positive thinking. Cancer feeds itself on many things, one of them is processed sugar, which is another reason why you should eat fructose. Cancer was nearly non-existent 50 years ago, the reason cancer developed is most likely through the higher use of chemicals to cheaply produce food, drug, and cosmetic products.
Also, herbal medicines do alot of the times work better then drug treatments, but it really varies what the case is, for example, most antidepressant drugs(paxil, prozac, etc) showed no more impact on people mildly depressed then a placebo. They just have a strong effect on very depressed people, yet plenty of other things were shown to have a similar effect, IE bananas increase serotonin levels, and things like that. The herbal alternative, St Johns Wort, was shown to be more effective then most anti depressants, its much cheaper, and it doesn’t cause kids to shoot up their school.
“There have been studies to see if “positive thinking” has any effect on cancer survival rates. And, the answer is NONE. It’s science, and if that’s pessimistic, well so be it.”
Studies are great, but alot of the studies, depending on who is performing the studies, have bias, studies can be manipulated, very easily, and it is a known fact that stress depresses the immune system, with a strong immune system, less cancer cells will survive.
If you want truthful information that is not biased, you should look at a multitude of sources and use common sense.

About nr 6: No, the tar does not cause cancer itself, but it makes the more dangerous chemicals stay in your lungs: The radon and polonium is glued to the lung wall with the tar. Even radon from buildings will stay that way and increase the effect. As radon is an alpha-radiant this will cause cellular damage and thus cancer that would not happen from outside the body.

#22: Apparently the author does not understand the concept of free market. The producers of oil and those who sell it have the right to price their product at any level the deem fit. The user has the right to or not to buy said product. The laws of a free market and supply/demand dictate that as long as people continue to buy said product at the current rate the the product is priced correctly. As you may notice people are now finding ways to cut back on usage. What will happen is that if the profit of the oil companies is affected negatively they will respond by adjusting their prices as needed to get the max return on their product.
Do I like the fact it takes over 50 bucks to fill up my Honda Accord? No. And I drive less, and if the prices do rise I will either take public transportation to work, by a motorcycle or ride a bike. If the cost of oil goes back down, then I might buy a 30 foot long SUV that gets 4 miles per gallon. Free Market is all about whether or not the price of the product is what I as a consumer feel is worth spending my resources on. If not I will use my resources where I see fit. Its basic economics, but I know most people are not fortunate enough to take that class in college and are completely oblivious of the concept.
The Free Market, my friend, is alive and well.

Um… #15 chills don’t make you sick…
It says right there that it shocks the immune system, making it less able to fight off viruses. Seems to me it’s actually the VIRUSES & other BUGS that make you sick… not the chill. Maybe that’s splitting hairs, but so is parsing the terminology that the big bang wasn’t an explosion. That word “explosion” is just a word to help lay people better visualize the process. The Cambrian Explosion, wasn’t technically an explosion, either, but that word is used as a descriptor.

About the ‘Chlorine water can damage skin’ holy hell you can say that again, I started swimming alot in chlorined pools recently, and now I have white dry spots all over my skin!

@Brandt:
Your points here are very well stated and completely understood. However, I think Penny was pointing out that speculators (and possibly corrupt governments) are forcing up the cost of oil so that the true market price no longer reflects the true market demand. Yes, people are cutting back, but they still buy gas because they have no other reasonable alternative. True free markets are priced based solely on true demand, without all the fishy unknowns of this current oil market. Nevertheless, your arguments are valid for the most part.
PS: I’ll let Penny respond to some of the other recent comments.

I like how half of these statements don’t have sources. On top of this most of these are not earth shattering concepts at all. Most of the health points revolve around the concept of moderation, which is just plain obvious.
The only one I kind of disagree with is the point about hard water being healthy. For some reason, the author did not decide to put the word moderation in front of this one. In the area where I live, many patients who have kidney stones can be linked to the tap water they are drinking constantly. The problem with hard water is it contains a lot of calcium. Sure this varies depending on where you live, but seriously, the word moderation should not have been left out of this point.

Brandt,
The free market never existed. It is an abstract simplification invented by Adam Smith. What Marc said is exactly my point.

Ben,
Just because an idea sounds plausible, doesn’t mean it is true. In fact, there have been extensive studies on whether positive thinking can help cancer recovery rates, and they have shown that the answer is no. Studies are better science than anecdotes or
guesswork based on plausible ideas.
Does stress depress the immune system? Yes. Does this mean that positive thinking helps cancer recovery–nope. The question is whether the improvement in the immune system is sufficent to kill the cancer cells. The answer is no.
Can studies be manipulated –YES. But, they are the best tool we have here. And, replication is part of the process.
As to herbal medicine : Serotonin Uptake inhibitors seem to not work–as determined by many recent studies. The is no evidence that depression results from a deficiency of Serotonin.
A more recent hypothesis is that
antidepressants work by aiding the growth of new brain cells—such regrowth is now know to happen in a limited way. Nice idea, as it takes weeks for anti
depressants to work–something that the Sertonin
deficiency hypothesis never explained.
However, there are many classes of antidepressants, and studies have shown that older classes–such as tricyclics and MAO inhibitors do work. And, they work better than St. John’s wort–since studies have shown it doesn’t have more than a placebo effect.
Yes, there was less cancer fifty years ago–not almost none. That was because of two reasons–one, fewer people survived to the age that cancer becomes common, and two, much cancer was misdiagnosed.
A recent redo of histology for old Mayo clinic samples showed that many people who were diagnosed with fatal TB actually had cancer.
There was FAR more chemical pollution fifty years ago, and FAR more than that a hundred years ago.
Fifty years ago, we had huge use of coal–full of radon and other carcinogens.
Fructose interferes with Leptin–the hormone that tells us that we are satiated.

j,
I recall many science books and tv shows that showed the big bang as an explosion.
It only made sense to me that it wasn’t, when I looked at the solution to the Einstein equations and discovered that it was not at all an explosion.
So you are CORRECT, and it was intended as a metaphor, by Leimatre, the mathematician who first discovered it as a special solution to the Einstein equations–but it widely misunderstood.
Stefan–YES. THANK YOU. BRILLIANT!

drip,
I like your webquote about Unix.
When the engineers at Xerox park invented the idea of the mouse, they studied little boys–who they observed liked to play with toy cars, and decided that was basic. It was
sexist.
But, in fact, they might have come to a different conclusion had they studied older boys, and even Girls! Because verbal commands are also very natural.
They might have even studied ….perish the thought–adults!
Me, I prefer words to pulling a little truck around and pointing little arrows–that is a pain in the neck, and it increases eyestrain, and it is pretty slow, actually.
Optimal would be a verbal command line interface–which now that we have good verbal interfaces is not that hard to implement.
Nobody pulls mice around windows on Star Trek–they talk to the computer. This led to a very scene in Star Trek IV–where Scotty on a trip to the
1980’s thinks the mouse is a ….microphone.
Of course if one is a gamer–one might want a different interface. I don’t play computer games–except chess.

some of these are absolutely true.. but some seem to be personal opinions.. thumbs down. 🙂

Bob,
Interesting, because I get Kidney Stones, and my doctors ( and the latest research studies) show that calcium actually suppresses kidney stones–even those made of calcium.
I was told to drink LOTS of milk. Milk has far more calcium than my local hard water.
But, I wonder if –as you say, your locals have more stones–and if it is really due to hard water and not
another factor ( worth a careful statistical study), whether it is the calcium or another mineral in that water that is the issue. Or, perhaps the combination of that mineral and calcium.
What is healthy for most is often quite unhealthy for special populations–for example: milk is healthy, but not if you are allergic to milk.
Yes, moderation is important. And kidney stones are interesting because many supposed healthy foods are –in the subpopulation of Oxalate Kidney stone formers–unhealthy. This includes Spinach, and dark green vegetables, and many nuts etc. They must be
eaten in moderation.

Bob,
I wrote my post rather quickly. It was not an academic research paper–so I didn’t include sources. HOWEVER, one can now run keywords through google and you will find all kinds of sources.
As to earth shattering, the title wasn’t “Earth Shattering Facts….”.
For example, you might do a google search on calcium and kidney stones.
There is a lot of false info in medicine. It becomes very obvious when searching for such things as proper treatment of kidney stones. One gets lots of inconsistent information from various professional medical sites–which is why one should then read the actual research papers –after searching on Medline.
So my basic point is–don’t trust common ( even common medical) wisdom.
Commonly believed –even plausible things–are often dead flat wrong.
Lots of examples of this in the history of medicine.
Justin says
What exactly is the basis for 51? Ever been in a street fight? Have you ever used Karate or “dirty fighting” in fight? Do you have any statistic you could point to to show that people who have taken karate or other self defense classes are less capable at self defense then those who do not? What makes you think Karate is “clean fighting?” Are you talking about Karate as a sport, or Karate as self defense? Were you aware there was a difference?
brick says
Most of these comments are flawless, until you look more closely. All then come down to using moderation in everything, and there is not just one cause for every condition. There is one main problem: there is no hard and fast rule for anything, really.
