In Beijing, a friend and I were talking about how to improve high-school teaching. I said two things would help: more personalization, and more movement. Movement really helps learning, I said. I read something about that recently, my friend said. She meant this post of mine (treadmill walking made it pleasant to study Chinese)!

Paul Sas has drawn my attention to a man with a remarkable memory:

JB is an active, articulate septuagenarian who began memorizing Paradise Lost at the age of 58 in 1993 as a form of mental activity to accompany his physical exercise at the gym. Although he had memorized various poems in earlier years, he never attempted anything of this magnitude. JB stated that he wanted to do something special to commemorate the then-upcoming millennium. “Why not something really challenging like, oh, ‘Paradise Lost’?” he said. He began by walking on a treadmill one day while trying to memorize the opening lines of the poem.

He eventually memorized the whole poem, about 11,000 lines. Apparently the scientists who studied him ignored the treadmill.

A learning psychologist might say that walking provides mental activation, we learn better when we’re stimulated. (For example, we learn better when we’re scared.) My point is treadmill walking produced an hedonic change: I found learning more enjoyable when I was walking.

What We See: Advancing the Observations of Jane Jacobs, a collection of essays, has just been published by New Village Press (who sent me a copy). Several of the essays are very good, such as those by Pierre Desrochers, Janette Sadik-Khan (in charge of improving New York City’s streets), Daniel Kemmis, Robert Sirman, and Mary Rowe, but my favorite was the one by Janine Benyus. Benyus came in contact with Jacobs when Jacobs phoned her to ask her to speak at the 1997 Toronto conference Jane Jacobs: Ideas That Matter. Benyus was thrilled to be speaking to the person whose writing she’d studied to learn how to write. Benyus wrote about increasing appreciation of the value of biomimicry, learning how nature has solved this or that problem to help us solve the same problem.

[On the Galapagos Islands] I watched a quiet engineer named Paul stand motionless before a mangrove as if in deep conversation. He finally called me over and pointed: “This mangrove needs fresh water but its roots are in saltwater, which means it somehow desalinates using only the sun’s energy. No fossil fuels, no pumps. Do you know how we do it? We force water through a membrane at 900 pounds of pressure per square inch, trapping salt on one side. When it clogs, we apply more pressure, more energy.”

Then Paul asked the question I’ve been working to solve ever since: “How is it that I, as a desalination engineer with a five-year degree and twenty-year experience, never once learned how nature strips salt from water?”

Contradicting the notion that you can find anything on the Internet, I cannot find any info about what I was told in a Beijing Starbucks: A few years, a city was started in Mexico where a million Chinese workers will manufacture stuff. Because of NAFTA, the stuff they make will have tariff-free access to the American market. And shipping from Mexico will be cheaper than shipping from China. The Chinese workers will come over for a limited time, such as one year.

I asked Brent if he had any comments on his experience (after he adopted an ancestral diet, his migraines and sinus infections stopped). He wrote:

The quality of my life (mental + physical health) improved even further when I started eating slices of butter throughout the day awhile back. For awhile, I was using spoonfuls of coconut butter/coconut oil and/or Greek yogurt for this satiation role, but once I added butter slices to the mix, I beefed up my nutritional ‘bag of tricks’ quite a bit. Of course, I had cooked in butter for a few years, but I never made the link to simply eat it in slices, despite enjoying its taste so much. And, a little bit goes a long way. I eat cultured butter from a few different brands and a few different locations of the world (hoping this diversification may carry extra beneficial side-effects: different strains of micro-organisms, etc.). I try to find brands that are pastured too (more naturally-occurring Omega-3′s, evidently). I usually suck on/chew on the butter slowly because I’ve found this has improved my oral health too: animal lipids (plus coconut oil) are good for epithelial tissue health (that’s why I rub coconut oil on my face and skin and rub butter, coconut oil, and yogurt on my hands). Pairing butter and coffee (I eat the butter; I don’t put it in my coffee; I drink my coffee black) has become a nice start to my day (Dave Lull even found a study speculating on the benefits of coupling hyperlipidity and anti-oxidants together in this way; I think it’s also a useful approach to detoxifying the liver), particularly when I know I am going to workout that morning–this little hyperlipidity kick seems to help in the gym too (when I am not fasting). Using butter slices in this manner is a nice compliment to fasting intermittently–these two practices allow me to enjoy low-caloric intake periods pleasantly. They set up my “feasts” nicely. Whenever I have a “grumbling” stomach, or I feel a “biting” sensation in my stomach, I eat a small piece of butter, and my mood and body tend to stabilize. And, like bacon and yogurt and eggs, it’s cheap. Butter has certainly been an excellent ‘cheap health option’ for me.

He later added:

Now I am working intently on Meta-Rules. Meta-Rules are simply ‘rules for making rules’ to live by. Three dynamics concern me deeply: (1) The problem of induction; (2) biochemical individuality; and, (3) factoring for the unseen. For instance, one of my nutritional Meta-Rules is: “Don’t consume anything that causes a negative physiological reaction.” From this Meta-Rule, I have deduced the following rule to live by (as one example): “Don’t consume high-fructose corn syrup.” A marker for monitoring this rule could be facial inflammation and ‘puffiness’ post-consumption, as one possibility. That’s an example of a higher-level precept empowering an individual to deduce for him or herself how that concept applies (or does not apply) in his/her own specific case (I like the term: Patient of One). Over time, I suspect that something like William Baines’ Biomedical Mutual Organization (BMO) could emerge if enough people were self-experimenting with Meta-Rules and interacting about their experiences and results. Amongst this cohort of parallel n=1 clinical trials, some convergence of Meta-Rules may occur, indicating ways that our bodies are the same, and also showing how our bodies differ individually when it comes to things like diet, exercise, and lifestyle design.

To explain why headaches can be due to inflammation, he pointed me to this.

Dan Wich, a faithful reader of this blog, told me that my work had helped him. I asked for details. He wrote:

I have a desk job and began to experience back pain that was aggravated while sitting. So I bought a desk designed for both sitting and standing, and spent most of my time standing.

I was on the lookout for improved sleep patterns because of your experiments, and I noticed similar results. But the biggest benefits I observed were unexpected. First, my ability to focus and prioritize improved while standing; sitting for long periods made me more likely to avoid challenging tasks. Second, I felt more creative while standing, avoiding the problem-solving tunnel vision I’d often get after sitting for a while.

Being able to switch between standing and sitting without changing anything else has led me to dismiss other causes for those mental benefits. And I wasn’t expecting to receive them, making me doubt the placebo effect is at work. So, I think I can corroborate your results of improved mental function while standing.
