Robert Heinlein: un-American Rebel With A Cause
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
- Robert A. Heinlein, American science-fiction author (1907-1988)
That's outrageous! Why, look at what our experts have done for us.
Our expert chemists have created chemical fertilizers and pesticides to put on our agricultural crops so megafarming agribusinesses can produce lots more food than our ancestors ever dreamed of. And diseases and weaknesses such as diabetes, allergies and heart disease at rates never previously imagined because our bodies can't cope with the chemical attacks over long periods of time. (Tests are usually over three years, seldom longer, as if nothing could affect our health over a long period of time.)
Other expert chemists, medical specialists, have developed drugs to rescue us from the ravages of those chemicals, which have also made their way into our air (over half a million kinds) and our drinking water (over 300,000 kinds).
Our expert medical doctors happily prescribe those drugs for the rest of our lives so we can stay on our feet and work harder than our ancestors ever dreamed. And, so they won't forget what to prescribe, many of them accept reminder gifts from the pharmaceutical companies. A comfortable arrangement for the experts.
Our business specialists, MBAs tucked neatly in safe locations, figure out how to manufacture things to make our lives easier. Our communications specialists devise ways to sell those products to us through advertising, making us believe we need stuff we seldom use. The facts that our lives are not easier, that we have more stress than any previous generation, take more drugs than any previous generation and buy so much we don't need that we have to have yard sales and to give other stuff to "needy" people in neighbouring countries is never mentioned, so we forget. (Donations by Americans are often sold in Canada, and vice versa, a fact seldom noted publicly.)
Our expert architects design skyscrapers so well that most people who have to work in them have their health compromised. Sick building syndrome--no one knows how it will affect our length of life--stands as a hallmark of modern architectural progress.
Our legal specialists are so good at defending bad guys with cash to spread around that few go to prison and the ones who do have short stays. Our lawyers have reputations worse than used car salesmen of the old days. Their accounting specialists advise them how to Hoover every available dollar from ordinary folks who know so little of the skills of relationships they don't know how to stay married, so little about money management that more cash goes out than comes in for too many people and so little about getting along with neighbours that whole television courtroom series have cropped up to document the conflicts and allow the rest of us to be voyeurs.
Our specialists have made us the great Western World are persuaded those who are not part of it envy to such extremes that some of them want to murder us because of it.
We are, in short, the epitome of progress. We have our specialists to thank.
Let's take a moment to consider the parts of their lives that our experts and specialists don't want us to think about. Would you expect to see one of them changing a flat tire? No, because they have roadside assistance insurance. Or is it because they have no idea how to change a tire? Or because they fear getting their hands dirty. Ask one.
Most pay little attention to their diet until they are diagnosed with diabetes, heart disease, have a stroke or are told point blank by their doctors that they are obese or dangerously overweight such that their lives are at risk. They know little about nutrition, what their bodies need to stay healthy.
Most have no idea how to fix their own computers, even how to keep dust out of them, and many don't even keep their security programs up to date. They don't change the oil in their own cars because they don't know how. They can't change a washer in a leaky tap/faucet. They have to call a plumber when their toilet plugs up because they have no idea how to use a plunger (or how to avoid plugging the toilet in the first place).
They don't plant their own gardens where they can grow pesticide-free and chemical-free veggies and fruit because they "don't have time." In fact, most don't have any idea how to tend a garden.
On the other hand, a high school dropout may know how to do all of these things and hundreds more. Does this make the dropout more fit for life in the 21st century than the highly educated person? Not necessarily. But maybe.
Consider this possibility. Something happens that causes the power to go out in your part of the world and you learn that it will be out for a whole year or more. Would you rather have the high school dropout who has had to survive by the seat of his pants for many years as an ally or one of the experts or specialists mentioned earlier in this article?
Of course you assume that such a thing will never happen, even though a terrorist bomb could accomplish it. The 30 million people of the US state of California believe their state will never sink into the Pacific either, even though scientists have been warning it would happen for years from a split of earth's tectonic plates along the San Andreas fault. Many Americans are unaware that what is known as a super volcano is brewing under Yellowstone Park, even though a blow that would darken the skies of the world possibly for years is overdue. These things can happen. Eventually one will. Some call it Armageddon, but it's really just nature in action.
Am I suggesting that high school and post secondary education is worthless or counter productive? Not at all. What is needed is a change of focus in our elementary and high schools. We need to teach children life skills, not stuff they know they will never need or use. How much do you remember or use of what you learned in high school? Would you have willing traded much of it for some of the life skills you have learned by experience since then?
Adolescents and young adults have trouble in high school often because they see how useless what they are forced to learn is and will be to them in the future. They know they need to learn life lessons--that desire to learn is instinctive--but they don't know what those lessons are or how to get them. They rebel. They drop out. They take drugs or alcohol, get tattoos, listen to music that could destroy their hearing, and so on. Eventually, most of them learn the lessons they need, get back on track and become upstanding citizens. But not quickly enough. Those lessons often come the hard way, by making mistake after mistake and learning from them. A few don't make it.
As radical as Robert Heinlein's suggestion in our opening quote seemed when you first read it, it makes more sense now. We have time to teach these life lessons and more. We simply need to eliminate what was better suited for 18th century schools than it is for today's world. In the 18th century kids learned life lessons at home. Today's kids can't learn them at home because many of their parents don't know the life lessons themselves to teach. With both parents working to earn enough to buy the fun things of life as well as what we believe are necessities, we need someone to teach the life lessons that used to be taught at home.
They aren't being taught at school today because the curriculum is too crowded with other (often unnecessary) stuff. They aren't being taught at home. And our young people experience more problems at school and outside of it than any previous generation.
This is a simple connect-the-dots problem and solution. By the way, I still don't know how to set a bone, but I can do most of the rest of what Heinlein suggested. It took me six decades of life to learn these lessons. I should have been able to learn them in school, before I needed them. You too.

Why You Are No Longer Just You
Until now you have likely thought of yourself as "me," an individual human of the homo sapiens sapiens variety, a single being trying to make its way in the world. That will change before you reach the end of this article.
What's more, any thought or fear you may have had that you could be cloned will be removed from your list of possibilities forever. (That reminds me, why did the original of Dolly the sheep, the first large animal that was cloned, not receive any of the credit while Dolly took all the credit and glory? The original sheep that was cloned doesn't even warrant a name for us.)
Each of us is not just one organism, the way we usually think of ourselves. We are actually a symbiosis of billions of organisms, only one of which has the DNA pattern we associate with ourselves. Our DNA gives us the cells we think of as "us." Most of the rest are bacteria, good bacteria without which we could not survive. Each has its own DNA that is nothing like our own.
Let's begin with places that other living things we loosely call germs enter our bodies. The mouth is a very important place to begin because it's the location where the first battles against invaders that could harm us are fought. We don't just have saliva in our mouths when we're not eating. Saliva is the vehicle that carries good bacteria that are our first line of defence against disease. Invading viruses or bacteria could enter our bodies through our mouths at any time.
Okay, we know that if their are going to be battles, they must be fought somewhere. The mouth would be as good a place to fight some as any, right? Not so you'd notice judging by commercials we see on television. How about those mouthwash ads that promise to kill almost every living thing in our mouth if we use it a couple of times every day? That means that we would kill off millions of bacteria in our mouth that are prepared to fight to the death to prevent harmful bacteria and viruses from entering our body.
However much or little you know about military engagements, you would likely agree that it doesn't make sense to kill off the first companies of soldiers that go into battle on our behalf. That is exactly what those bacteria-killing mouthwashes do.
What do mouthwashes really do that is beneficial? They try to kill collections of fungi that grow on the top of the tongue at the back of the mouth. These fungi are the main causes of bad breath. That's what you wanted to avoid, right? Yes, but brushing the back of your tongue with your toothbrush just before you finish brushing your teeth and rinsing will do the same thing. The exact same thing. Only the brush will do it better because it can separate those little forests of tongue things and flick away the fungi, whereas the mouthwash may not be that successful.
If you want your first line of defence against disease caused by most kinds of bacteria and viruses to hold fast and keep you healthy, don't kill it off because you believe the commercials. Big corporations are in business to make money off ignorant people, not to help us maintain good health.
The nose is one of the vulnerable places where germs can enter. Lo and behold, the nose also harbours a boatload of good bacteria to fight disease on our behalf, as well as the mouth. When are the defences of the nose most vulnerable? When the nose gets cold, the bacteria that defend it tend to weaken, to lose their power to fight. They don't necessarily die, they just go kind of dormant. They are very subject to cold.
Along come the viruses (about 200 different kinds of them) that cause us to develop a "cold." Have you ever wondered where that word "cold" came from to describe the runny nose, watery eyes and the rest of the discomfort? It came from an event that lowers our defences against cold viruses, getting our nose cold. A cold nose event isn't the only way to get a cold, nor does having your nose get cold guarantee you will get a viral cold. It's just a common way for the attack of the cold viruses to begin in our body while its primary defences are weak.
The other common place where cold viruses enter our body is through the eyes. Viruses ride the fluid in our eyes as it swashes around the eyeball, then eventually makes its way into the back of the eye where they find body cells to invade or blood cells that will carry them farther inside. We don't have many natural defences against invasion through our eyes. But eye fluid is not exactly conducive to growing or transporting live viruses, so having dry eyes is a condition we want to avoid.
Kissing with the tongue, having an open wound and exchanging bodily fluids through sex are other methods by which germs enter our bodies, only in those cases from another person rather than from air, food or liquid. Those practices are not necessarily risky in terms of increasing our vulnerability to disease. In each case we have good bacteria to defend us against invasion by germs and microbes (two words which mean essentially the same thing). We are as apt to get good bacteria from another person as bad bacteria.
While we have bacteria at work in every organ of our bodies, the greatest proliferation of them is in the stomach and gut. Bacteria actually perform the work we call digestion. Without them we could starve to death even if we ate all day long.
Have you ever wondered why some people could eat a mountain of ice cream without gaining an ounce, while another person gains two pounds just from sniffing a cupcake? The one who easily gains weight is "blessed" with a very efficient digestive system, lots of good bacteria that digest as much as possible of the nutrition they eat. The glutton with the beanpole body style has a very inefficient digestive system, not nearly enough good bacteria to help digest the food that passes through. (I know, it ain't fair.)
Some biologists have estimated that we may have more bacteria in our bodies than we have of our own body cells. While that may sound absurd, remember that just a few years ago very few people believed that anything could live in our bodies other than our own cells. And some bad bacteria and viruses that somehow managed to survive and cause diseases.
That brings us--briefly--to good viruses in our bodies. Are there any? Can a virus be good. As odd as that sounds, remember that just a few years ago (or a couple of minutes ago) you believed that all bacteria were bad. DNA experts tell us that strings of gene patterns in some human chromosomes are identical to gene patterns in some viruses. At some point in our past, some humans have accommodated bad virus genes into their own chromosomes. Now we consider them "natural," part of our own line of defence.
Medical science isn't certain if the virus genes within our own chromosomes help to protect us against certain diseases or prevent our immune system from recognizing disease-causing germs because they have genetic material similar to our own. The odds are that both are true, with different people and different diseases. (Doesn't that confuse the issue!)
We are not subject to some kinds of diseases that other large animals are. And we get a few diseases that other mammals don't. The reason likely has something to do with those strings of virus genes within our own. Some of us can get HIV/AIDS, while others of us could never contract the disease. Heart disease, cancer and other diseases have difference between people, even of the same family. The difference may be who has what viral gene sequences within their own DNA. And that may depend on which viruses were accommodated and which rejected within each person's lifetime. It is possible for DNA to change slightly over a lifetime.
As this gene accommodation and rejection of competing genes from viruses is part of human evolution that is going on today, we can't be certain how it works. Our bodies are still works in progress. We occupy a small section along the production line called life.
As for cloning yourself or cloning anyone else, you can now see that a single organism of DNA could be replicated, but no two could ever have the same combinations of bacterial organisms as each other because their symbiosis would be different. As most of our learning is based on excruciatingly small details we each learn as babies and very young children, no two people with the same DNA could ever be the same either, just as no two identical twins have the same personalities.
Even two people that began life with the same DNA might not be identical as adults because of gene accommodations through their respective lifetimes--that is, they may have different susceptibilities to diseases, for example. Medical science may be able to help us to grow new body parts (we can even grow new brain cells), but the subject of whole body cloning must be left to science fiction writers.
If you take nothing else from this article, at least do yourself a favour and don't kill off the good bacteria that are helping you to live a healthy life. Without them, you can't be healthy and eventually you may die from your own misdeeds.
