Sometimes a pair of chopsticks is just a pair of chopsticks

Impressions

To have a meal with chopsticks is to engage in the immaterial world of relationships and ideas. People don’t use chopsticks in a restaurant to show their dexterity. Rather, it demonstrates one can navigate different cultural contexts, adapt to various social environments, and demonstrate a level of open mindedness. These are all fine purposes, but they have little to do with the pragmatic task of moving pieces of food from the plate to the mouth. And in many contexts, the temptation is to master chopsticks to fake sophistication. Seth Higgins, “On Lug Wrenches and Chopsticks, in Front Porch Republic

When I worked in an office, back in the early days of this century, I used to walk across the street to the grocery store on my lunch break to make a salad at the salad bar, which I took back to eat at my desk. I have always loved salad bars, maybe because when I was a kid they were the only chance I had to choose whatever I wanted to eat. Choice and abundance! Very American. Anyhow: I enjoyed my salad-bar lunches, but I found them difficult to eat. A fork is lousy at picking up raw carrots, no less so if they are grated — and more so if the fork is one of the plastic ones they give you at the store. Actually forks are pretty lousy at picking up raw vegetables, period. Radish? Cucumber? I felt like I was trying to kill Dracula. Have you ever tried eating raw spinach with a plastic fork? And let’s not even talk about those baby ears of corn.

Then I found, in my desk drawer, an unused pair of takeout chopsticks from a Chinese restaurant. And they worked. They worked really well. They picked up everything, from baby corn to the last little bits of shredded carrot. They worked so well that to this day I eat salad with chopsticks — at home, when nobody is watching — simply because they are more efficient than a fork.

Sometimes, to paraphrase something Freud may or may not ever have said, a pair of chopsticks is just a pair of chopsticks. And pretty much all the time, you’re better off choosing the right tool for the job instead of thinking of tools as symbols.

A cultural sleep

Impressions

Jessica Gamble describes new techniques and technologies whose inventors would radically reduce or eliminate the human need for sleep:

Transcranial direct-current stimulation (tDCS) is a promising technology in the field of sleep efficiency and cognitive enhancement. Alternating current administered to the dorsolateral prefrontal cortex through the thinnest part of the skull has beneficial effects almost as mysterious as electroconvulsive therapy (ECT), its amnesia-inducing ancestor. Also known as ‘shock therapy’, ECT earned a bad name through overuse, epitomised in Ken Kesey’s novel One Flew Over the Cuckoo’s Nest (1962) and its 1975 film adaptation, but it is surprisingly effective in alleviating severe depression. We don’t really understand why this works, and even in today’s milder and more targeted ECT, side effects make it a last resort for cases that don’t respond to drug treatment. In contrast to ECT, tDCS uses a very mild charge, not enough directly to cause neurons to fire, but just enough to slightly change their polarisation, lowering the threshold at which they do so.

Using a slightly different technique — transcranial magnetic stimulation (TMS), which directly causes neurons to fire — neuroscientists at Duke University have been able to induce slow-wave oscillations, the once-per-second ripples of brain activity that we see in deep sleep. Targeting a central region at the top of the scalp, slow-frequency pulses reach the neural area where slow-wave sleep is generated, after which it propagates to the rest of the brain. Whereas the Somneo mask is designed to send its wearers into a light sleep faster, TMS devices might be able to launch us straight into deep sleep at the flip of a switch. Full control of our sleep cycles could maximise time spent in slow-wave sleep and REM, ensuring full physical and mental benefits while cutting sleep time in half. Your four hours of sleep could feel like someone else’s eight. Imagine being able to read an extra book every week — the time adds up quickly.

The benefits are so obvious that Gamble doesn’t actually argue in favor of all this technological wonder and post-evolutionary glory; instead, she insists that no present-day person can logically argue against it:

The question is whether the strangeness of the idea will keep us from accepting it. If society rejects sleep curtailment, it won’t be a biological issue; rather, the resistance will be cultural…. Such attempts are likely to meet with powerful resistance from a culture that assumes that ‘natural’ is ‘optimal’. Perceptions of what is within normal range dictate what sort of human performance enhancement is medically acceptable, above which ethics review boards get cagey. Never mind that these bell curves have shifted radically throughout history. Never mind that if we are to speak of maintaining natural sleep patterns, that ship sailed as soon as artificial light turned every indoor environment into a perpetual mid-afternoon in May.

Setting aside, for the moment, the matter of sleep, there’s an interesting assumption lurking beneath that paragraph, and I think it’s worth ferreting out, because the opponents Gamble imagines share it.

Area man still not eating his veggies

Impressions

A school system in New York has dropped out of the federal school lunch program because the fruits and vegetables they’re forced to serve kids are winding up in the trash. The USDA has known for decades what’s needed to build a successful nutrition education program — one that actually changes people’s eating habits. But the confident language obscures just how hard it really is.
