You frequently hear people wishing for a return to “the good old days.” Study your history and learn the science, is what Dr. Amy Tuteur argues over at Science-Based Medicine. The days of yore were tough, and a lot of us alive today wouldn’t have made it way back then if it weren’t for modern science (me included).
Yes, there is obesity, heart disease, cancer, and more. But, the average lifespan just keeps climbing. As recent as the early 1900s, the average expected lifespan was only 48. And this was when food was organic, people got lots of exercise, and when doctors still made house calls.
Advocates of alternative health have a romanticized and completely unrealistic notion of purported benefits of a “natural” lifestyle. Far from being a paradise, it was hell. The difference between an average lifespan of 48 and one of 77.7 can be accounted for by modern medicine and increased agricultural production brought about by industrial farming methods (including pesticides). Nothing fundamental has changed about human beings. They are still prey to the same illnesses and accidents, but now they can be effectively treated. Indeed, some diseases can be completely prevented by vaccination.
So, don’t knock modern times. It may not be perfect, but it’s sure better than polio, cholera, plague, dysentery, and smallpox. In the good old days, “your doctor couldn’t do much more than provide comfort until your body defeated the illness, or until the illness defeated you.” Doesn’t sound like much fun to me.
Myth or fact: Wearing a bra causes breast cancer? Answer: MYTH.
Apparently, there’s an Internet rumor going around (and we all believe those, don’t we?) that women who wear bras have a higher rate of breast cancer than those who don’t. Here is what Dr. Ted Gansler, director of medical content for the American Cancer Society, told The New York Times:
There is no scientifically credible evidence of this, he said, and the proposed mechanism–that bras prevent elimination of toxins by blocking lymph flow–is not in line with scientific concepts of how breast cancer develops.
He goes on to say that the idea that bras might cause breast cancer is so ludicrous that it’s doubtful scientists will ever waste research dollars on it. So, don’t burn your bras yet, ladies, and don’t believe everything you hear on the InterWebs.
Remember the Ouija Board? It’s a staple of the middle school sleepover, to fill up the minutes when you aren’t playing “Light as a Feather, Stiff as a Board.” Well, Hasbro has released a pink version of the game and some folks are really…well…freaked out.
Meet Stephen Phelan, communications director for Human Life International, who believes that using a Ouija Board, “will leave a person’s soul vulnerable to attack.”
“It’s not Monopoly. It really is a dangerous spiritual game and for [Hasbro] to treat it as just another game is quite dishonest.”
Some comments on the product’s Amazon page chastise Hasbro for marketing Ouija Boards to young girls. Reviewers say Hasbro should be ashamed, and one person advises to buy this only if you hate your child:
Guns don’t kill people, people kill people, right? Why doesn’t Amazon.com sell automatic weapons or child porn? Because it is understood that these are very dangerous.
Um, what? Child porn and guns are the same as Ouija Boards?! That seems a bit ridiculous. And, actually, it’s not understood that these are dangerous. Has there ever, EVER, been an incident reported where something bad happened (legitimately) because of a Ouija Board? They have been debunked many times. How does a Ouija Board work?
What makes the pointer move? An effect similar to that which occurs in dowsing, known as the ideomotor effect. This is a fancy name for involuntary/unconscious movement, such as a dowser’s hand flicking enough to move his stick when he passes over an area he knows has water.
Sorry to get all “science-y” on you, but this should explain that a Ouija Board is nothing to be afraid of. It’s a game, and just a game. So, paint it pink, blue, purple, or yellow–it still won’t conjure up anything more than harmless fun. Don’t believe the experts? Then take Skeptic.com’s advice and debunk it yourself:
To prove this, simply try it blindfolded some time. Have an unbiased bystander take notes on what words or letters are selected. Usually, the results will be unintelligible.
I actually think it’s pretty smart of Hasbro to create a pink version and market it to tween girls. They know *exactly* who their audience is!
Turkey gets a bad reputation as the cause of post-Thanksgiving “food comas.” This is where you’re so sleepy that you can barely function once the last bite of pumpkin pie has been swallowed. A myth has long been perpetrated about tryptophan, an enzyme in turkey, as being the cause for sleepiness. Well, that is just plain wrong.
Tryptophan also can be metabolized into serotonin and melatonin, neurotransmitters that exert a calming effect and regulates sleep. However, L-tryptophan needs to be taken on an empty stomach and without any other amino acids or protein in order to make you drowsy. There’s lots of protein in a serving of turkey and it’s probably not the only food on the table.
Also, the concentration of tryptophan in turkey is the same as the amount found in beef and chicken, and even more tryptophan is contained in cheese and pork.
So, why are you so sleepy after all that turkey dinner?
Overeating is the culprit in this myth. Ingesting an excess of food can slow blood flow and oxygenation, which makes you feel tired. Many people are led to believe it’s the turkey that specifically makes them long for their pillow, but in reality, it’s just the quantity of dinner.
Don’t blame the turkey if you have to go to bed early tonight.
Today is the third Friday the 13th in 2009, the most times that combination can possibly occur in one year. It’s rumored that millions of people postpone surgeries or travel on this day, and many are frightened that something bad will happen to them today. Is it true? Are many people paralyzed with fear over Friday the 13th?
It appears not.
…in Chicago, for example, neither O’Hare International Airport nor United Airlines has noticed any drop in the number of people flying on Friday the 13th.
“It’s an old wives’ tale,” said United spokeswoman Robin Urbanski in an e-mail.
The same goes for two of the biggest hospitals in the city–Northwestern Memorial Hospital and the University of Chicago Medical Center–where it appears people are just as likely go to go under the knife that day as any other, and aren’t rushing to the doctor, either.
And, investors don’t care, either. Friday the 13th is typically a good day for the stock market.
So, don’t let the superstition get to you. Travel, invest, and plan events for today as you would any other day. That’s what most of us are doing, anyway. As Stevie Wonder said,
When you believe in things
That you don’t understand,
Then you suffer,
Superstition aint the way
There’s no shortage of products that claim to alleviate arthritis. Copper bracelets are some of the more popular products sold. It is believed by some that wearing a copper bracelet or wrist strap will relieve the pain and discomfort of arthritis. Here is how one site claims it works:
It is no secret that copper is a most excellent conductor of electricity, and besides that, the skin is as much an entry point in the body as a barrier.
Micro doses of copper enter the body and bolster the immune system, and as it’s on the skin, it enters as and when needed (not as in dietary copper).
The copper bracelet seems also to emit elemental and molecular vibrations and other physical phenomena such as a corona effect of the ends of the bracelet.
These vibratory emissions appear to convey some medicinal benefit. In the case of body pains due to some rheumatoid arthritic condition, it appears to be very effective indeed.
Really? Just all from that one tiny bracelet?!
Sounds all very scientific, doesn’t it? Well, as with most products that hint at science but don’t back it up with real facts, it’s bunk. A study just released by a group of scientists in England has concluded that there is no scientific proof of medical benefit from wearing these bracelets. The test subjects experienced no difference in pain, discomfort, or stiffness while wearing copper jewelry. Any benefit felt someone wearing a copper bracelet or wrist band can likely be attributed to a placebo effect.
So, if you thought wearing a piece of copper to cure arthritic conditions sounded too good to be true, you were right.
Sure, most of us techno-geeks and science nerds get worked up when some movie or TV show blatantly mungs some bit of science or technology (the “sound” from explosions in space, for instance), but do you know what gets our beanie-hat propellers really spinning? When our non-technically minded friends buy some pseudo-science claptrap that they heard from “them”, or read on the Internet.
Nothing fits that mold better than confusion about radiation. Just like with any other word or phrase, it’s always a good start to understand its origins. The word radiation is derived from the word radius, which is the distance from the center of a circle to its edge. So, any phenomenon that spreads out in all directions from where it originates can be said to radiate, and thus can be called radiation.
Sadly, few call sound “acoustic radiation”, or perhaps people might get the commonality. Either that, or they’d think that loud noises will give them cancer. Scratch that idea.
That bad, cancer-causing kind of radiation is “nuclear radiation” (that’s not a real term, just used for emphasis) and is the kind being talked about when something is called radioactive. Its real name is ionizing radiation (because it can strip an atom of electrons, turning it into an ion), and it consists of actual subatomic particles getting thrown around. While it is associated with things like nuclear reactors and bombs, it also just happens naturally. Almost all of the lead in the earth, for instance, once started out as another element, and was transformed into lead by the process of radioactive decay.
Ionizing radiation is bad, and can injure or kill us, because when atoms get ionized, they become very chemically reactive, and all kinds of unintended reactions start to happen in our cells. Cells can die, or worse, accumulate genetic mutations and turn cancerous. When cancer had another cause, however, ionizing radiation can help, as its targeted use can kill just the cancer cells and spare healthy cells.
Then there’s electromagnetic radiation, otherwise known as radio waves or light waves. Electromagnetism is one of the four fundamental forces of the universe, and I won’t attempt to explain it here. But, in the frequencies/energies in which we use it to run our modern world of technological marvels, it is not, I repeat, not, ionizing radiation. The electromagnetic radiation from your radio, Wi-Fi, cell phone or even microwave oven (which is by far the most powerful electromagnetic device most of us encounter) can not injure you the same way ionizing radiation can. Electromagnetic radiation is a wave, just like a ripple of water in a pond. What radiates out in such a ripple is not particles, like an explosion, but the motion of the water.
(Note: A damaged microwave oven CAN injure you, in the same way that it affects the leftovers you heat up: by heating the water molecules inside your body. NEVER use a microwave oven with a broken door, hinge, latch, etc.)
Now here’s the tricky bit. Although nearly all of the confusion between ionizing radiation and the benign electromagnetic kind comes from the common word being used in the sense of “radiate”, there is another connection.
One of the great mysteries of our universe is that in certain situations, matter and electromagnetic radiation behave like both a wave AND a particle. Light is the most famous example, and is how science first came across the phenomenon. Some ionizing radiation, like x-rays and gamma rays, which are high-energy particles like other ionizing radiation, are ALSO very high frequency electromagnetic waves. Ain’t the universe just the coolest?!
So, while that connection is true, it does not mean that your cell phone, which emits electromagnetic “radiation” of very much less energy/frequency, where the difference in quantity becomes a difference in kind, is radioactive in the sense of a nuclear bomb. Ditto with the cell phone towers, radio station antennas, etc.
In short, Stevie Wonder said it best: “When you believe in things you don’t understand, then you suffer; superstition ain’t the way.”
If you’ve watched TV with commercials lately, chances are you’ve had to suffer through a Jamie Lee Curtis yogurt ad. After hearing the claims made in this ad, you might think yogurt is the next super food. Yogurt will help my digestive problems! Yogurt will keep me healthy! Yogurt will paint my house!
Okay, we made up the last one. But, seriously…has yogurt ever gotten so much healthy street cred? The secret ingredients in Activia, and other similar products, are probiotics. According to the New York Times:
Probiotics are live micro-organisms that work by restoring the balance of intestinal bacteria and raising resistance to harmful germs. Taken in sufficient amounts, they can promote digestive health and help shorten the duration of colds. But while there are thousands of different probiotics, only a handful have been proved effective in clinical trials.
The bottom line is this: there are a lot of different strains of probiotics. Not all of them have been proven to work. The claims of most of these products are unsubstantiated, as recent lawsuits and rulings have declared. In fact, a $35-million decision in a class-action lawsuit against Dannon (makers of Activia) is forcing them to list the specific probiotics used in the yogurt, as well as remove the word “immunity” from the package.
Science-based Medicine has a great article that busts the “immune-boosting” myth. The author does a great job of explaining exactly what is your immune system, and why any product claiming it can “boost” it is ludicrous.
What does that mean: boost the immune system? Most people apparently think that the immune system is like a muscle, and by working it, giving it supplements and vitamins, the immune system will become stronger. Bigger. More impressive, bulging like Mr. Universe’s bicep. That’s the body part I am thinking about. What they are boosting is vague, on par with chi/qi or innate intelligence. They never really say what is being boosted.
The other popular phrase is “support”. A product supports prostate health, or breast health or supports the immune system. It sounds like the immune system is sagging against gravity due to age and needs a lift.
The immune system, if you are otherwise healthy, cannot be boosted, and doing those things you learned in Kindergarten health (reasonable diet, exercise and sleep), will provide the immune system all the boosting or support it needs.
Most experts agree that more research is needed into these claims to see what helpful effect probiotics have on the body.
“The evidence for the general immune strengthening is just not there,” said Barry R. Goldin, a Tufts professor who helped discover LGG but no longer receives royalties from the patent.
So, eat yogurt and other probiotic products because you want to. Don’t eat them and think you’ll be protected against all of society’s ills. Instead, go for a walk, eat some broccoli, and watch this Activia parody from Saturday Night Live.
As Halloween approaches, it’s time for some old urban legends to be dusted off and circulated. First stop: Bobtown, Pennsylvania where the kids won’t be allowed to go door-to-door looking for treats. The scrooges in the small community have cancelled trick or treating. Community leaders say the radical step is being taken to keep kids “safe.” Safe from what, exactly? We’re not sure.
With a party at the fire hall, he says both the kids and the candy they receive would be safe.
Huh?
As Lenore Skenazy pointed out in her book “Free-Range Kids”:
Was there ever really a rash of candy killings? Joel Best, a professor of sociology and criminal justice at the University of Delaware, took it upon himself to find out. He studied crime reports from Halloween dating back as far as 1958, and guess exactly how many kids he found poisoned by a stranger’s candy?
A hundred and five? A dozen? Well, one, at least?
“The bottom line is that I cannot find any evidence that any child has ever been killed or seriously hurt by a contaminated treat picked up in the course of trick-or-treating,” says the professor. The fear is completely unfounded.
Give kids their costumes and candy. They are in more danger of being hit by a car than poisoned treats. So, keep them safe by following some simple common sense rules, like:
Always accompany young children and, if they’re too old to have an uncool parent tag along, be certain they travel in groups that are as large as practical. Be certain they know not to accept rides from, or go inside the homes of, strangers.
Get your kids to agree to a move along a pre-planned route and stay in the neighborhood. It’s best to know generally where they are and to set a time at which they must return home to prevent unnecessary risk or worry.
Be sure the costumes have reflective surfaces and have your kids carry flashlights and glo-sticks. Caution the trick-or-treaters to stick to the sidewalks and be very aware of moving vehicles and only cross at designated crossing areas and traffic lights. Spirits may be running high (in more ways than one), and nighttime driving can also affect the vision of the soberest driver.
The most you have to worry about from Halloween candy is a high dentist bill.
The New York Times does a good job of calling Bill Maher to task for his ignorance and misinformation on the flu vaccine. Maher hosts a chat show on HBO and is usually known for his political commentary. But, lately he’s been spending a lot of time leading people astray about vaccines and the H1N1 virus.
He [Maher] said he did not believe that healthy people were vulnerable to dying from the new H1N1 virus. This contradicts statements from the World Health Organization and the Centers for Disease Control and Prevention that young, healthy people from ages 5 to 24 appear particularly vulnerable to this flu. About a third of the 76 children who have died of H1N1 since April have had no underlying health problems.
Here is Maher getting schooled by Dr. Bill Frist, a heart surgeon.
Do not listen to talk show hosts when considering your safety and health. Please talk to doctors and other health professionals. He may have a big mouth, but Maher may not be right. Get the facts for yourself.
