Fact 1: For the last few weeks, I’ve been studying Chinese using a flashcard program called Anki. It’s an excellent program but boring. I’ve never liked studying — maybe no one does. Fact 2: I’ve had a treadmill for a very long time. Walking on a treadmill is boring so I always combine it with something pleasant — like watching American Idol. That makes it bearable. I don’t think listening to music would be enough.

Two days ago I discovered something that stunned me: Using Anki WHILE walking on my treadmill was enjoyable. I easily did it for an hour and the next day (yesterday) did it for an hour again. The time goes by quickly. Two boring activities, done together, became pleasant. Anki alone I can do maybe ten minutes. Treadmill alone I can do only a few minutes before I want to stop. In both cases I’d have to be pushed to do it at all. Yet the combination I want to do; 60 minutes feels like a good length of time.

I’ve noticed several related things: 1. I could easily study flashcards while walking. This was less mysterious because I coded walking as pleasant. 2. I can’ t bear to watch TV sitting down. Walking on a treadmill makes it bearable. This didn’t puzzle me because I coded TV watching as pleasant and sitting as unpleasant (although I sit by choice while doing many other things). 3. I have Pimsler Chinese lessons (audio). I can painlessly listen to them while walking. While stationary (sitting or standing), it’s hard to listen to them. 4. When writing (during which I sit), it’s very effective to work for 40 minutes and then walk on my treadmill watching something enjoyable for 20 minutes. I can repeat that cycle many times. 5. Allen Neuringer found he was better at memorization while moving than while stationary. 6. There’s some sort of movement/thinking connection — we move our arms when we talk, we may like to walk while we talk, maybe walking makes it easier to think, and so on.

You could say that walking causes a “thirst” for learning or learning causes a “thirst” for walking. Except that the “thirst” is so hidden I discovered it only by accident. Whereas actual thirst is obvious. The usual idea is that what’s pleasant shows what’s good for us — e.g., water is pleasant when we are thirsty. Yet if walking is good for us — a common idea — why isn’t it pleasant all by itself? And if Anki is good for us, why isn’t it pleasant all by itself? The Anki/treadmill symmetry is odd because lots of people think we need exercise to be healthy but I’ve never heard someone say we need to study to be healthy.

The evolutionary reason for this might be to push people to walk in new places (which provide something to learn) rather than old places (which don’t). To push them to explore. David Owen noticed it was much more fun  for both him and his small daughter to walk in the city than in the country. He was surprised. When I drive somewhere, and am not listening to a book or something, I prefer a new route over a familiar one. If I am listening to a book I prefer the familiar route because it makes it easier to understand the book.

Maybe the practical lesson is that we enjoy learning dry stuff when walking but not when stationary. Pity the 99.9% of students who study stationary. Ideally you’d listen to a lecture while walking somewhere, perhaps around a track. Now and then I’ve interviewed people while walking; it worked much better than the usual interview format (seated). The old reason was I disliked sitting. Now I have a better reason.

Imagine if, to get the news, you had to go somewhere and have it read to you! What a joke. From an article in the Washington Monthly about on-line education:

If Solvig needed any further proof that her online education was the real deal, she found it when her daughter came home from a local community college one day, complaining about her math course. When Solvig looked at the course materials, she realized that her daughter was using exactly the same learning modules that she was using at StraighterLine . . . The only difference was that her daughter was paying a lot more for them, and could only take them on the college’s schedule. And while she had a professor, he wasn’t doing much teaching. “He just stands there,” Solvig’s daughter said.

The excellent article misses something big, however:

A lot of silly, too-expensive things—vainglorious building projects, money-sucking sports programs, tenured professors who contribute little in the way of teaching or research—will fade from memory, and won’t be missed.

Edward Jay Epstein, a wonderful journalist, has just published The Hollywood Economist. I asked the publisher for a free copy. About two-thirds I’d already seen, mostly in Slate. The back cover says “Freakonomics meets Hollywood saga” but I’d say “Spy meets The New Yorker” — not that many people would understand “Spy”. It has a Spy-ish “here’s how things really are” aspect but with fewer embarrassing stories. And it has a New-Yorker-ish broad and deep view. (Epstein has often written for The New Yorker.) Like both Spy and The New Yorker it is very well-written. Although I’ve visited his website many times, I didn’t know about The Assassination Chronicles: Inquest, Counterplot, and Legend (three books combined) nor Who Owns the Corporation: Management vs. Shareholders (69 pages). He’s currently writing a book about the 9-11 commission. From his profile: “I taught political science at MIT and UCLA for three years but then decided that researching and writing books was a far more educational enterprise.”

I’m fond of arguing that the Ten Commandments was a very political document. Notice it’s aimed at men? Notice that women aren’t protected, much less children? That’s because men had all the power. No one has said they already knew this or that I was wrong.

I thought of the Ten Commandments when a friend from Amsterdam wrote me about a recent experience of hers:

A very old man asked me to come to his apartment, and he would donate a bike to the project.  I went over to get it, and it was half a bike, and it was locked to a pole…had obviously been there for years.  The temperature was well below zero.  It became clear that he was in fact super-lonely, and torn between usual Dutch suspicion of strangers… and desperation for human contact.  He finally pleaded with me to come up to his apartment (where he obviously lived alone) but not before we spent 15 minutes trying to saw that rusty old bike loose, with his World War II-vintage hacksaw with missing teeth.

You may know that Dutch people are the tallest in the world, reflecting a very high standard of living. But — if this old man is not unusual — alleviating the loneliness of old people isn’t part of the Dutch social contract, admirable as it may be.

I recently watched the Frontline program Sick Around the World. It suggested that that old man isn’t unusual. In England, where doctor visits are free, a doctor said he has several patients who come weekly, purely because they’re lonely. In Japan, some patients have their blood pressure measured very often — presumably for the same reason. In Taiwan, if you see a doctor 20 times in one month someone from the government will come to talk to you. Not about loneliness — about overuse of medical care. The Frontline program made nothing of any of these facts, which were included to show that access was easy. That’s not all they show. What if the British doctor had said that several patients visit him often because they need water? Then we’d be shocked. Yet the idea that everyone needs human contact isn’t mysterious or controversial.

My explanation is there’s a double whammy: Not only do lonely old people have little power, it’s also clear that their problem (loneliness) isn’t caused by a “chemical imbalance”. So no drugs can be sold to treat it. And there’s no diagnostic category. It’s another example of gatekeeper syndrome. When these lonely old people exert what little power they have by visiting their doctor, the doctor — I’m assuming — doesn’t do anything to get rid of the loneliness. Even if you visit 20 times in a month.
