I'm sorry, alcohol

I've been on a booze break for some weeks now. My intention is to follow through on this indefinitely, but it appears I may have it all wrong. This page summarizes several hundred studies showing why: Alcohol and Health.

At first, I figured none of the studies suggested causation, only correlation. At least one study suggests that the apparently cognitive benefits in older adults who drink moderately (as opposed to not at all) are nonexistent after controlling for intelligence in young age: http://www.ncbi.nlm.nih.gov/pubmed/12878923.

But then I came across one damning section: "Alcohol Abstainers Who Begin Drinking Reduce Their Risk of Cardiovascular Disease":
During a ten year study of 7,697 non-drinkers, investigators found that 6% began consuming alcohol in moderation. After four years of follow-up, new moderate drinkers had a 38% lower chance of developing cardiovascular disease than did those who continued abstaining. Even after adjusting for physical activity, Body Mass Index (BMI), demographic and cardiac risk factors, this difference persisted.

This study is important because it provides additional strong evidence that the reduced risk of cardiovascular disease among moderate drinkers is a result of the alcohol itself rather than any differences in lifestyle, genetics, or other factors.
(from King, Dana E., Mainous, III, Arch G. and Geesey, Mark E. Adopting moderate alcohol consumption in middle-age: Subsequent cardiovascular events. American Journal of Medicine, 2008 (March), 121(3).)

So I may have to reconsider...

On becoming a potato

It seems that some people, interested in attempting meditation, but untrained in any techniques, resort to a process that's not so useful: they sit with eyes closed, think of nothing, and try to be aware of nothing. One Tibetan lama whose work I'm fond of has a nice description of this: "it's almost like becoming a potato." Supposedly, if you pour enough hours into this practice, you'll slowly vegetate.

As it happens, this method does have one useful purpose: it's a great way to fall asleep quickly! I used to use it as a child, when my mind was racing at night and I got tired of all the churning. I'm glad I didn't keep it up while awake, though :)

So give it a go. Just not for very long.

A quote on meditation

Just stumbled upon this clever quote from the great Tibetan yogi Milarepa about meditating properly.
When you run after your thoughts you are like a dog chasing a stick; every time a stick is thrown, you run after it. But if, instead, you look at where your thoughts are coming from, you will see that each thought arises and dissolves within the space of that awareness, without engendering other thoughts. Be like a lion, who, rather than chasing after the stick, turns to face the thrower. You only throw a stick at a lion once.
Oh, and now I am reminded of the moniker assigned to me at the monastery: Chokyi Senge, which in Tibetan means "Dharma Lion" (and "Dharma," in turn, is something like "the truths expounded by the Buddha").

By the way, if the analogy of a dog chasing after a stick isn't clear, I think of it like this: thoughts can arise by themselves. When you're meditating on the breath, they often do. What often ends up happening is that you'll sort of start "owning" the thoughts, or becoming attached to them. At that point you often start narrating them, and you're off to the races, riding one thought to the next. Instead, if you stop believing that you own or are responsible for the thoughts, they quickly melt away.

Now to find the thrower...

My brain made me do it?

Good article over at CNN about how brain differences that correlate with psychopathic behavior can be seen in children as young as three.

The article gives me hope, but as usual, the comments do not:

I swear I didnt kill that person.. My brain made me do it...

Ah, snideness. The easiest way to bury your head in the sand while trying to look clever.

Then there's no way that you can be rehabilitated. We'll have to remove you from society....permanently.

Armchair neurology: if it's in your brain, then there's no way to change it! And then a scary threat... punctuated by a scary... ellipsis.

There was, however, one comment that I am glad to have read:
I know I'm one of these people. My lack of guilt and fear of consequences have led me to make some huge mistakes. I've had to work very, very hard to make some major changes in the way I live my life and make decisions. This is a very interesting study. I hope that good things come from it.
What do you know? Sociopaths are people too! Of all the things I'm glad for, high on the list should be my acute sense of guilt, remorse, shame, and the host of other social emotions that keep me both from causing harm and being vilified.

Do you punish your child differently depending on how intentional you deem his act to be? Would you label him a monster if you were to learn that you passed on genes that made it painfully difficult for him to act in accordance with most of society? Or would you do your damnedest to make sure he stops hurting himself and other people?

Meditation is boring

There, I said it. A friend and I were chatting earlier today about ways of revamping the brain. I wanted to suggest meditation -- as I have a thousand times in the past -- but I hesitated, and not only because I hate sounding like a preachy bastard all the time. It's also because I've been lousy at keeping up my practice myself, and I suppose it's not hard to understand why.

The thing is, meditation isn't supposed to be fun. I know that as well as anyone. But if I feel it's so boring that I don't do it, maybe it's time to be more practical and less idealistic. So here's an alternative I suggested to him. It's one I do myself when I'm not too lazy.

Pick up a challenging magazine that's only marginally interesting to you. I use The Economist. Spend five or ten minutes reading articles, being careful not to let your mind wander from the topic at hand, or even far from the details of the passages. Every paragraph or so, give yourself a very brief quiz ("What was this paragraph about? The PM of Japan. What's his name? Naoto Kan. Check."). Try to be as engaged as possible, allowing those details to seep into longer-term memory, even as you read on.

It's similar to attention meditation in that you're expected to carefully monitor your attention and detect when it's going off course. It's easier in that the subject is generally more engaging (than your breath, for example), and that you're able to wander further from the exact subject before you must accuse yourself of being off course (the sensation of the breath at your nostrils is a rather precise percept).

But even this simple exercise is not trivial to do well for most of us, and I believe that practicing it is a step in exactly the right direction if you're looking to strengthen the circuits in your brain that allow you to live your life in a directed and conscious manner (more on that soon).

So if you're not ready to give full-blown meditation a try, or are just feeling lazy, reach for a nearby magazine or book and give your brain a more manageable workout.

Revisiting a hard-to-pronounce Greek word

I guess it's high time I update this thing. Had a few thoughts yesterday, and figured I'd commit one of them to writing.

In Nov 2009 I wrote about a condition called anosognosia. That's a condition where you have a disability but don't know you have it. I'll repeat one of the quotes:
Neuroscientist Edoardo Bisiach at the University of Milan in Italy reported one 74-year-old stroke patient who repeatedly claimed that his left hand belonged to the doctor examining him. The doctor finally grasped the paralyzed hand between his own two and held it up to the patient's face.

"Whose hands are these?" he asked.

"Your hands," the patient replied.

"How many of them?"

"Three."

"Ever seen a man with three hands?" the doctor asked.

"A hand is the extremity of an arm," said the patient. "Since you have three arms, it follows that you must have three hands."
When we are attacked or affronted by another person, how do we decide how much to blame the offender? For many people, part of that decision is based on how much we think the other person should know better.

Well, how do we know whether they should, or even can, know better? For an amputee with anosognosia, surely he should know he's missing an effing arm. And still, no amount of yelling at him will change the fact that he does not.

I really enjoy learning about neurological disorders because they remind me how profoundly differently other people may experience the world. And I'm constantly reminded that the only thing people seem to have in common is that we're all trying to do well for ourselves, with the limited mental resources we have.

What mistaken beliefs might you hold you don't know about? Are you sure you'd recognize or accept them if they were pointed out to you by even your closest friends? I'd like to end again with the same quote as last time. It's something I believe fiercely:
"Looking at patients like Mrs. M. can be spooky at first," says Ramachandran, a neuroscientist and physician at the University of California at San Diego, and the Salk Institute nearby. "But then you realize you're really looking at yourself, in amplified form."
Do yourself a favor and spend an extra 15 seconds asking yourself if you're really really sure you're right the next time someone criticizes you. You just might be missing an arm.
