Daily Dose of Common Sense

“I heard from a friend of a friend that…” How many times have you received an email with this sort of opening? Usually what follows is some sort of urban legend, offers of free money, or dire warnings about the health of your children. But, not everyone might spot an e-hoax as easily as the next person.

That’s why debunking sites, such as Snopes.com and Hoax-Slayer.com, are so important. If I hear a crazy Internet rumor, one of these sites is my first stop to verify what I’ve been told.

For example, “Man Hit by Lightening, Then Mauled by Bear” is true. However, the alert that several women have died from sniffing perfume samples sent to them in the mail is false. Way false.

So, check with reputable sources before you believe what you read. Even people you know and trust can be misinformed.

It is always surprising to get in an elevator in a hotel and see the numbers go from twelve to fourteen. We all know there’s a number missing. Are some people really still paralyzed with fear over the number thirteen?

There are many theories as to why thirteen has gotten a bad rap. Some say it has Christian roots revolving around the Last Supper. Others say the ancient Egyptians believed the number thirteen to be a symbol of death. There are also Norse and medieval ties to this number as well. Regardless, we all know superstitions are just crazy, right?

For example:
- Knocking wood won’t really change your luck (there’s no such thing as luck).
- Spilling salt doesn’t bring the devil (it means you’re clumsy).
- Sneezing doesn’t let your soul escape (it means there’s an irritation in your nose).
- A sudden shiver doesn’t mean someone is walking on your grave (it means you’re cold!).

And yet, the fear over the number thirteen persists. Friday the thirteenth is not just a horror franchise; many people actually alter their plans when this day rolls around. A small percentage of people polled said they would request a room change if given accommodations on the thirteenth floor.

A recent USA TODAY/Gallup Poll suggests a large majority of Americans — 87% — would be comfortable with a 13th floor room assignment. But 13% say they’d be bothered by a 13th floor room assignment, including 9% who would be sufficiently bothered to seek a room change.

The poll shows women, people age 65-plus and those with annual household incomes below $30,000 are more prone than average to seek a new room if assigned to the 13th floor.

The trend of renaming the thirteenth floor in buildings and hotels began in the late 19th century. However, in a rash of rationality, some newer hotels have bucked this nonsense and have installed elevator buttons with thirteenth floors. I say let the 9% move to a different floor–and get a grip. But, until then, I guess I’m staying on the “fourteenth” floor of my hotel.

Not all claims of environmental friendliness are created equal. In fact, some are outright lies. That’s where Greenwash comes in. Greenwash is a blog in The Guardian that seeks to expose, “the exaggeration, absurd claims or downright lies that big business makes about its green credentials.”

For a sample of what the author, Fred Pearce, takes on, here’s a bit from a post, Green advertising rules are made to be broken:

Big companies can always drive a coach and horses through the rules, greening their corporate image by mixing a couple of heavily marketed green products into a range of many more thoroughly un-green products.

Again, oil companies are notorious. This column has returned several times to the greenwash strategies of BP and Shell, plastering the country with posters and double-page adverts extolling their involvement in green energy, which in truth makes up a tiny (and recently diminishing) part of their investment.

Yea! We love it when anyone exposes lies and untruths, whether it’s big business, small business, or no one’s business. A lot of Greenwash’s content relates more to Europe, but the environment is a huge topic worldwide right now. It’s great that someone is sifting through the green spin to find the truth.

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.

My daughter had a birthday yesterday, and I had several well-wishers ask if she was bouncing off the walls because of sugar. Well, no, actually she was no more hyper yesterday than any other day. Yes, she ate a cupcake, Cracker Jack, Nerds, and a bunch of other junk, but she’s a healthy kid. That, and there’s no such thing as a “sugar high.”

I know, it takes a second for it to sink in. We have been led to believe that sugar makes people (especially kids) hyper. But, it’s just not true. Our bodies do a really good job of regulating the sugar we intake. Many studies have been done on this topic and the conclusions are the same: the amount of sugar that a kid eats does not affect his or her level of activity.

Jessie from Rational Moms did a great in-depth debunking of the sugar high myth. I highly recommend giving it a read.

So, don’t worry about your kids being up all night after eating a bunch of sugar. They’re up late because they want to be up late. Duh.

This past week, The Amazing Meeting 7 congregated in Las Vegas. Today, the final day, $1 million was on the line as self-proclaimed psychic Connie Sonne stepped up to take JREF’s infamous challenge.

If you don’t know about the challenge, here’s the deal. James Randi and his organization have offered a $1 million prize to anyone who can offer scientific proof of the paranormal. Since 1964, no one has been able to win the money. About 1,000 people have applied for the challenge, and testing has been completed on astrology, ESP, dowsing, psychics, faith healing, and more. No one to date has been able to prove their abilities are real.

Today’s applicant also goes home without the money. Asked to dowse three cards, Ms. Sonne failed. To read more about the test and the set up, read this JREF blog thread.

If you believe you have a paranormal “gift,” then submit your application to JREF and try to win the million bucks. Until then, we’ll remain skeptical about anyone who claims to possess paranormal abilities.

My three-year old loves ghosts. She loves any book with a ghost in it, and Boo Berry cereal is always a huge hit. But, she’s never afraid of them, and doesn’t consider them any more real than Spongebob Squarepants. To her, as well as rational people everywhere, ghosts are fictional, amusing things. We can say this because the existence of ghosts, or any kind of paranormal activity for that matter, has never been credibly documented or recorded using true scientific methods.

Most Americans believe that July 4th is the day independence from Britain was declared. Only it wasn’t. Independence was actually declared on July 2nd.

On July 2nd, the Second Continental Congress approved a resolution declaring independence. In fact, John Adams himself believed July 2nd would be the day Americans would commemorate the anniversary.

On July 3rd, 1776, John Adams predicted in a letter to his wife that “the Second day of July, 1776, will be the most memorable Epocha, in the History of America. I am apt to believe that it will be celebrated, by succeeding Generations, as the great anniversary Festival.”

So, why do we celebrate on the 4th? First, that was the date Jefferson wrote at the top of the Declaration of Independence. Also, that was the day the final draft of the document was voted on and approved. It should be noted that this vote was not unanimous. New York did not agree to the declaration until July 19th.

The signing of the document did not take place on the 4th, as many believe. Some men did, in fact, sign that day. But most signatures were penned at the official signing ceremony on August 2nd, with a few more coming even later. The final signature was added in 1781.

So, celebrate with gusto today. But, next year, remember July 2nd, too.
