We have been reading since the invention of writing around the fourth millennium B.C. But computer screens, tablets and phones, products of the 20th century, are relatively new. So scientists have been studying reading comprehension. The question they examined is whether we absorb information more fully on paper or on the screen. 

Findings based on laboratory experiments, polls and consumer reports support what we already know. That screens drain more of our mental resources while we are reading and make it harder to remember what we read when we are done. That students who read texts on computers and then answer multiple-choice questions perform worse than students who read the material on paper. That paper books and documents are easier to navigate and therefore may be better suited to absorption, which is why people understand what they read on paper more thoroughly than what they read on screens. Seventy percent of people who work long hours in front of computers report symptoms including eyestrain, headaches and blurred vision, which collectively comprise a condition known as computer vision syndrome. Also, many people think of reading on a computer or tablet as a less serious affair than reading on paper. So they take a lot of shortcuts, skimming and scanning for keywords, rather than appreciating the honey-tongued phrases and mellifluous metaphors they'd find if they weren't so set on simply getting to the end. Busted!

Screen readers are also less likely to engage in metacognitive learning regulation by setting goals, rereading difficult sections and testing themselves on how much they've understood. You don't feel ownership of an e-book as you do a paperback or hardcover edition. All of these findings are common sense. Obvious to anyone who's ever tried to read an article as carefully on the screen as they can when printing it out and failed, though few try. Because e-reading is convenient! And often free! Which are the real benefits, indeed. The studies don't seem to justify the research funding required to publish them. Nothing is for nothing and you gotta pay the bills, I guess.

But what boggles me is that knowing that paper beats screens 9 times out of 10, that the only time the experience is comparable is when we look at images, I still persist in writing this blog thinking it will get appreciated while knowing full well that those who click on it do so only for the pictures. So here's one to brighten your day.

I was watching the TV show Naked and Afraid last night as I sometimes do. The show teams together two strangers, a man and a woman, who attempt to survive on their own for a period of 21 days in some remote and isolated region. Some of the locales featured include the Australian Outback, the Amazonian rainforest and the African Savanna. The man may have a military background, or be an adventurist or deep sea fisherman. Sometimes he's an ordinary dude who lives with mom. The woman is a park ranger or extreme fitness enthusiast or "just a mom" herself. Sometimes the couple quarrel, sometimes one or both "tap out" (quit) in a fit of anger or illness. It is satisfying to see them actually make it through the challenge and reach their extraction point. The victors are usually exhausted, emaciated, begrimed and bare ass naked. 

Even more satisfying, at least for me, is the occasional ass shot, snuck in at strategic intervals to boost viewership, of course. It's co…


In my days in the working world, doing the traditional 9 to 5 thing - although when I was a teacher it was more like 10 to 2 and 6 to 9; and as a doctor it was often 6 to 6 - I saw how easy it is to fall into the traps of so-called civilized life. I'm talking about modern vices. Things like drinking, smoking, drug use, promiscuity, and a diet of processed food, with or without animal flesh.

During my senior year of high school I decided it was necessary for me to abstain from these five vices. Each day that I didn't 1. drink alcohol, 2. smoke cigarettes, 3. do drugs, 4. eat meat, and 5. have sex or masturbate, was a day lived in the right direction. The direction of purity, divinity, wholesomeness, God consciousness. It was a way of distancing myself from my more earthy peers, who even at the tender age of 17 were indulging in many of these fleshy pursuits, and on a daily basis. I had soccer teammates who smoked a pack of cigarettes, getting their fixes before school, between …


I hereby proclaim that June is meditation month. And July and August and some of September too. For me at least. During the hundred days that comprise summer, give or take, I have taken it upon myself to "assume the position" for approximately one hour each day, usually divided into two 30-minute sessions. During this time I sit in front of a candle flame, let my breathing subside, and with it my mental activity, and literally count the seconds.

The reductive tendency that is emblematic of science has penetrated schools of meditation, and there are many, each of which advertises its particular breed as, if not being the best, at least boasting novel or specific benefits not found in other forms of meditation. 

For example, there is mindfulness, which is the monitoring of thoughts. There is concentration or focus, as on an object or the breath. There is transcendental meditation, which uses the inward repetition of a phrase, or mantra, to "allow your active mind to easily …
