Have you had corn today?

You did, whether you know it or not.

Check out this quote from the book Free (47):

Historians often look at the great civilizations of the ancient world through the lens of three grains: rice, wheat, and corn. Rice is protein-rich but extremely hard to grow. Wheat is easy to grow but protein-poor. Only corn is both easy to grow and plump with protein.

What historians have observed is that the protein/labor ratio of these grains influenced the course of civilizations based on them. The higher the ratio, the more "social surplus" the people eating that grain had, since they could feed themselves with less work. The effect of this was not always positive. Rice and wheat societies tended to be agrarian, inwardly focused cultures, presumably because the process of raising the crops took so much of their energy. But corn cultures - the Mayans, the Aztecs - had spare time and energy, which they often used to attack their neighbors. By this analysis, corn's abundance made the Aztecs warlike.
It is an interesting theory. Of course, there are way too many variables to say that growing corn is the reason why those people groups were war-like, but it does lead you to think about what people do with their left-over energy. In fact, there are a lot of things you can do with your spare energy such as being altruistic, using your imagination, research and innovate, and artwork. But of course, that free time also means that you don't have to be as team oriented because you aren't as reliant on others. I certainly hope we are not destined, because we eat more corn than you ever realized.

Today, we use corn for more than just food. Between synthetic fertilizer and breeding techniques that make corn the most efficient converter of sunlight and water to starch the world has ever seen, we are now swimming in a golden harvest of plenty - far more than we can eat. So corn has become an industrial feedstock for products of all sorts, from paint to packaging. Cheap corn has driven out many other foods from our diet and converted natural grass-eating animals, such as cows, into corn-processing machines.

As Michael Pollan points out in The Ominivore's Dilemna, a chicken nugget "piles corn upon corn: what chicken it contains consists of corn [its feed], but so do the nugget's other constituents, including the modified corn starch that blues the thing together, the corn flour in the batter and the corn oil in which it is fried. Much less obviously, the leavenings and the lecithin, the mono-, di- and triglycerides, the attractive golden color and even the citric acid that keeps the nugget fresh can all be derived from corn."

A quarter of all the products found in an average supermarket today contain corn, Pollan writes. And that goes for the nonfood items, too! From toothpaste and cosmetics to disposable diapers and cleansers, everything contains corn, even the cardboard they're boxed in. Even the supermarket itself, with its wallboard and joint compound, linoleum and adhesives, is built on corn.
It's worth it to know what you are eating - not only for the dietary reasons, but maybe so you don't find yourself thinking war-like thoughts with your neighbors!

You don't think the way you think you think

I love this Bertrand Russell quote: "It has been said that man is a rational animal. All my life I have been searching for evidence which could support this."

All you have to do is take a good look at the G-20 convention and protests going on this week in Pittsburgh to see that often we have no rational idea of why we do the things we do. For example, how do destructive actions promote change to help people? "The atmosphere turned destructive along Forbes Avenue, where storefronts, including Pamela's Diner, were smashed in. Windows at the campus police station also were damaged. Businesses on South Craig Street also were vandalized, including Irish Design Center and Quiznos."

You don't have to go to vandalism to find irrational behavior. You can pretty much look anywhere you want. In the book All Customers Are Irrational (5), the author talks about how, if you really want to predict future behavior, you absolutely do not try to answer with rational explanations. As it turns out, the answer to predicting future behavior is quite rational - you look at past behavior.

Trying to find a rational answer for why you do things is much more difficult than you think. Rather than the subconscious being that part of the brain that kicks in here and there but usually handles the most basic stuff and our conscious part of the brain being, well, the brain of the operations, it is the other way around - only about 5% of the conscious portion of our brains being used to make decisions, and it is usually being notified after the decision has been made.
What that means is that you don't really know why you often do things, instead you are generally justifying why you did that after the fact.

Newsflash: we humans are pretty complex creatures. We are far more emotional and communal, sometimes in strange ways, than we are rational. Understand this, and we may have something that can help our businesses, our jobs, and our relationships.

Say NO to blindspots

Here is a neat trick I learned from the book Traffic to get rid of blindspots:

While sitting in the driver's seat, lean your head against the driver's side window. Now adjust your mirror so that the edge of your sight barely touches your car. Lean right so that your head is between the driver's seat and the passenger seat and do the same thing for the passenger side mirror.

When you sit back upright, the mirrors will probably be facing further out than you are used to, but it should show cars in the side mirrors that you can't see in the rear-view mirror. This is all assuming you actually use the mirrors...

Roundabouts


I've loved roundabouts from the time I started driving. They seemed to make sense because when you were at an intersection, many cars could be moving to their destinations whereas at a stop sign only one or two generally go at a time. Many people that I have known over the years don't like them, and some even fear them.

I finally feel vindicated (lately I have to derive some kind of pleasure even from the small things). The pictured roundabout from Laweiplein is a cool one that incorporates cyclists and pedestrians in a high volume area - and was incredibly effective.

From Traffic, (124):

"A properly designed roundabout can reduce delays by up to 65 percent over an intersection with traffic signals or stop signs. Sure, an individual driver who has a green light may fly through a signalized intersection much more quickly than through a roundabout. Roughly half the time, however, the light will not be green; and even if it is green there is often a rolling queue of vehicles just starting up from the previous red."
