I discovered a year ago that walking makes it pleasant to study boring stuff — as I put it then, boring + boring = pleasant. I am still a little amazed. (more…)

A Chinese teacher in Los Angeles named Yang Yang, whom you can see in this video, wrote this on her website:

I believe that we all have our own niche – something so unique and innate to us that we enjoy every second of it and can naturally do better than others. Teaching Chinese is my niche.

I think this is the beginning of wisdom about human diversity — a big improvement over judging people by how “smart” they are, as so often happens. (To a college professor, smart = able to imitate a college professor.) My theory of human evolution emphasizes the need for diversity of occupations. In ancient times, occupational diversity arose because different people enjoyed doing different things.

But I also think Yang Yang is wrong in two ways. First, I don’t think your niche is innate. I think it can be changed. I think we can come to enjoy and excel at many jobs that we do not enjoy at first. This is the other side of procrastination. Just as we dislike doing things simply because we haven’t done them in a long time, we like doing things simply because we did them yesterday. Habits are pleasant.

I also think that where you fall on a pro-status-quo/anti-status-quo (conformist/rebel) dimension is not innate. I think it has a lot to do with your birth order (first-borns are more pro-status-quo), as Frank Sulloway says in Born to Rebel. I didn’t read Amy Chua’s Battle Hymn of the Tiger Mother expecting to think about birth order and rebelliousness but that’s what I ended up thinking about.

A new study supports my idea that walking and learning are connected. Normally I found it boring to study Chinese flash cards. While walking, I found it pleasant. You could say walking made me more curious. Just standing on the treadmill didn’t have this effect.

The study divided men and women in their 60′s into two groups: (a) walking for 40 minutes/day and (b) stretching. At the end of the study, for persons in the walking group, part of the hippocampus — which is associated with learning — had grown. For persons in the other group, that part of the hippocampus got smaller. Several other parts of the brain, not associated with learning, did not differ between the groups.

In the excellent BBC series about the history of design (The Genius of Design), chairs played a large role.  Perhaps a fifth of the show is about them, far more than any other product. Yet I rarely use them and own only a few. I sit while socializing but otherwise usually work reclining (on a bed or in a rocking chair) or standing up. Long ago I discovered that if I stand a lot I sleep better. Since then I’ve spent a lot of time on my feet for someone whose job doesn’t require it.

My self-experimental discoveries led me to avoid about 99% of the food sold in a typical store — granola, cake mixes, flour, rice, breakfast cereals, and so on. Most of what I avoid is carbohydrate. Just as we are pushed to sit in chairs, we are pushed to eat carbohydrate. I don’t think carbs cause obesity — it’s more complicated than that — but they raise blood sugar (making diabetes more likely) and rarely supply essential fats. They are also poor source of microbes, which I’m sure you need to eat.

Over the last 30 years, designers have focused more and more on sustainability, “green design”, and so on. I think of this as the second half of the industrial revolution — cleaning up the mess. As far as I can tell, designers have not yet started to understand that we need certain things from our environment just as we need certain things from our food. Here are some things I think we need from our environment: 1. Sunlight in the morning. Some buildings have daylighting to save energy. 2. Faces in the morning. 3. Absence of fluorescent lights at night. 4. Movement throughout the day. 5. An hour of walking per day.
