Does Mt. Dew shrink your penis?

By Philip Copitch, Ph.D.

Dear Dr. Phil,


There is a rumor going around my school that Mt. Dew will shrink your penis. Is this true? If so how come they can legally sell this product?

Paul, Central Valley High, Redding CA.

Does Mt. Dew shrink your penis?


The simple answer is NO!

I am glad that you used the word "rumor" in your question. It seems that you were suspicious.

The problem with rumors is that if they are repeated often enough, they start to seem like old information. Tell the rumor several more times, and it starts to sound like a fact.

Similar rumors have to do with Mt. Dew lowering sperm count and/or shrinking testicles. All bull honkey!

When you come across a rumor, question its authority. Who is telling you this and why? Are there credible facts that can be verified? Is the rumor logical? Personally I like to ask, "Something that important should have facts to prove it, can you show me the facts?"  Statements like, "Everyone knows it," or "My social studies teacher said it," are not facts.

Dr. Phil's opinion about Mt. Dew


Overall Mt. Dew is liquid candy and should be consumed like a treat. It is very high is sugar, salt, and caffeine. It has no nutritional benefits. I personally like the taste of it. Enjoy it sparingly such as on your birthday, Christmas, and D&D all nighters.

Nanny state or caring society?

By Philip Copitch, Ph.D.

Dear Dr. Copitch,


I read your article called "New images on cigarette packs" and found myself getting angry. Why do people think that they can tell me what to do? I like smoking, and I am aware that it may be harmful to me. But it is my life and I still choose to smoke. I should be able to "opt out" of the nanny state and be allowed to live my life my way.

Grumpy in Oxnard

Hi grumpy in Oxnard,



I think I understand your desire to be left alone to smoke to your heart's content, but you live in a caring society. If I happen to be walking down the street and see you keeled over and wheezing, maybe having a heart attack or suffering from lung cancer, I'm going to call 911 and get you some help. 


This help comes with a big price tag and all of us pay this price tag. You can't "opt out" of our society easily. I like the concept of free will, but the reality of your free will can be very expensive for us as a whole.


According to the CDC:


  • During 2000–2004, cigarette smoking was estimated to be responsible for $193 billion in annual health-related economic losses in the United States ($96 billion in direct medical costs and approximately $97 billion in lost productivity).
  • The total economic costs (direct medical costs and lost productivity) associated with cigarette smoking are estimated at $10.47 per pack of cigarettes sold in the United States.
  • Cigarette smoking results in 5.1 million years of potential life lost in the United States annually.

Chinese Herbal Medicine must be good because so many say it is good.

Dear Dr. Phil.

Last year you came to my AP Psychology Class at Shasta High. You were very informative and funny. You said that we could email you if we had a question... so here goes.

My friend's mom has gone 100% mental over Chinese medicine. She has an herb solution for everything. She is positive that there is a conspiracy keeping the truth about the power of Chinese medicine a secret so that doctors can get rich.

Is Chinese medicine better than American medicine?

Thanks, Sara

Is Chinese medicine better than American medicine?

Great question Sara,

The fact is that Chinese and American medicine are the same. Medicine is based in scientific fact, and in China if you can afford medicine you get the same treatments as you get in this country. Alternative medicine was (is) only used in poor, rural areas where there is little access to modern medicine. In fact, in the middle of the last century China was in the forefront of medical research. So, how come so many Americans believe that Chinese folk remedies are better than medicine (American, Chinese or French)?

It is important to look at how this phenomenon entered American culture. To help you get this information please take the time to listen to the podcast linked below. It is from Skeptoid.com. Their motto is Skeptoid: Critical Analysis of Pop Phenomena. I find Skeptoid's analysis of a subject to be scientifically sound and educational.

Mao's Barefoot Doctors: The Secret History of Chinese Medicine (Skeptoid #259) - Westerners' belief that Chinese have long relied on alternative medicine is due in part to being duped by book publishers.

The transcript (Read) is a synopsis, so I recommend listening to the podcast for the whole story.

May I recommend:

While I'm on the subject to of Skeptoid.com, I highly recommend their award winning web site: Skeptoid: Critical Analysis Podcast

and specifically their podcast on critical thinking: The Importance of Teaching Critical Thinking

Be well,

New images on cigarette packs

The U.S. Food and Drug Administration recently showed of the new "warning" images that will be on all cigarette packs by the end of 2012. 


Some of the images are relatively mild:


While some are in your face gross:









The big question is "Will these warning graphics help people to stop smoking, or better yet, never start?"

The simple answer is yes.

These warning labels are product specific advertisement, and it is well documented that advertisements work. In 2006, the tobacco industry spent $12.4 billion on advertising, not to keep newspapers and magazines afloat, but to replace customers that die from their product. This 12.4 billion represents a doubling in expenditure since 1997.  Read the FTC report.


Health and Human Services Secretary Kathleen Sebelius said on June 21, 2011, 

Somebody said when they first saw the warnings: ‘These are really gross.' Well, they are. We want kids to understand smoking is gross, not cool. And there's really nothing pretty about having mouth cancer or making your baby sick if you smoke.

"I heard that teens aren't influenced by these scare tactics" 


Most people start smoking before age 19.  A common reason teens start to smoke is to say "screw you" to their parents, school, or authority in general. This attitude is fleeting for most teens. So over time, knowledge will  overcome anger. And advertising (warnings) take time to seep into the mind.


Smoking for teens is a statement. The more the teens see the bigger picture, the less effective their "statement" will be. 

A closing thought:

Teens are substantially more likely to smoke if one of their parents smoke. Some parents wonder if their teens learn anything from them... the simple answer is... Yes!

No Child Left Behind - a disservice to our children

by Geri Copitch, veteran teacher:

As someone who has taught in both an underperforming school and a high achieving school I’ve always had a problem with No Child Left Behind (NCLB). The concept that all students - without exception - can and must be proficient (at grade level) readers by third grade, was not run past any real life teachers who’ve ever taught in schools serving real kids. It is an ideal that we all strive for, but it’s not reality. So, I was surprised to hear a former assistant secretary of education in the George W. Bush administration, Diane Ravitch, come out against standardized testing and privatized charter schools.
Professor Ravitch acknowledged what I’ve experienced, that there are many factors that affect a child’s success in school, with teachers themselves being just one factor. Home and community life have a huge influence, as do the resources available to the students once they’re in school. As a newly minted teacher, I was surprised to learn that there were students in my second grade class who didn’t own any books - honestly, not one! How can we hope to mold competent readers when they have no reading material at home? When parents don’t model (demonstrate) reading? A co-worker who taught kindergarten at the same school told me she had one little girl who had never held a pencil or a crayon...Never! How can these children possibly get to the same proficiency level as a child whose parents take them to the library, occasionally buy them books, read them bedtime stories from the time they are barely able to sit up, and hand them paper and pencils to scribble with?
Ravitch was a strong advocate of NCLB. It was a program she felt would help schools and teachers hone in on areas that needed improvement, and make that their goal. Instead, it become a charge to reform schools using a hatchet to fire whole teaching staffs, while missing improvement goals completely. It became a one size fits all, fill-in-the-bubble approach. “No Child Left Behind has turned into a timetable for the destruction of American public education”, she told the radio host.
When schools are closed down for being underperforming, new schools open to replace them. Unfortunately, some of these schools, mostly those that are run by educational corporations, are allowed to winnow out underachieving students, making the school’s performance numbers improve. “If they’re not educating the same kids, then they’re not doing better.” In the end they are doing a grave injustice to those students who need the most help. These children are slipping through the cracks and are indeed, being left behind.
Vouchers and the push for homeschooling have the same chilling effect on public schools. They aren’t pushing public schools to improve, they are leaving them with nothing.
For schools to improve, we need parent and community investment in them. Not just money (though that helps) but time and interest. As Susan B. Anthony once said: If all the rich and all of the church people should send their children to the public schools they would feel bound to concentrate their money on improving these schools until they met the highest ideals.
When you look around the world, you see that those countries who provide free education to all their children are the countries that value democratic ideals. We used to be a nation that valued our free public education system. It was part of defining who we were. Now we have become a nation that worships at the altar of free enterprise. We value the business model which places very little value in the creative process, the very process that made us the envy the world over. We have become a nation of the bottom line, and our children, instead of becoming creative souls, will become commodities. Our children and the nation will suffer because of it.

But what about larger numbers times 11

After Prof. Benjamin's video last week, a few smart alecks pointed out, "But that is only 2 digits, how about larger numbers?" Fair question. I know two ways to multiply larger numbers by 11- both fun! In a few minutes you will know both!

Dr. Phil has fun with a little math.
