Open thread / Links / Aaargh

So I wrote this great (by my standards, anyway,) post, and then there was a glitch and it disappeared. Totes frustrating.

So while I re-write it, here’s an Open Thread / Links post. Feel free to chit-chat, ask questions, whatever. Just keep things civil or whatever.

Some things I’ve been reading:

1. The incredible story of one couple’s trip across the Democratic Republic of Congo: Lubumbashi to Kinshasa. (I actually read this a while ago, but have been meaning to recommend it.) Story is notable in several ways:

A. The raw descriptions of what life is actually like in the heart of the DRC, where even Coca Cola can’t go because there are no roads.

B. The perspectives on what has happened since the end of colonialism (basically, the collapse or outright destruction of colonial infrastructure like roads and buildings):

When I walk around our cities, I often think about what their ruins will look like to explorers in a thousand years
“We also pass a ruin of what once must have been a grand building. The walls are marked with logos from a Belgian University. This must have once been some scientific study centre of sorts.”

 

C. It was the first thing I’d read in about a decade that gave an actually positive impression of religion.

 

2. Real History of the World, which is kind of like my blog, but devoted to the conspiracy theory that all human life began in Africa and then spread out from there to the rest of the world. “But wait,” I hear you saying, “Isn’t that, like, the accepted scientific consensus on the origins of humanity?” Why yes, yes it is. But Real History of the World thinks that “they” (“albinos”) are trying to keep you from knowing that.

Their site is part actually accurate, part inaccurate (jfc, “Black Celts” are not black-skinned people, they are Welsh people with dark hair like Catherine Zeta-Jones:

This is what the old books mean by "Black Celts"
This is what the old books mean by “Black Celts”)

and part insight into the irrational paranoia of people who hate you.

This website is a good demonstration, btw, why I don’t believe conspiracy theories.

 

3. More perspectives on people who hate you (or at least me): Black Girl Dangerous’s This Is What Rihanna’s BBHMM Video Says About Black Women, White Women and Feminism

“Yes, there are images of a woman being kidnapped, held hostage, and even hung upside down from the ceiling while topless. These are the kinds of images we see a lot in violent revenge films. They can be upsetting and harmful. I didn’t like seeing them here. But they’re also not the entire story.

Let me tell you what I see when I watch this video: I see a black woman putting her own well-being above the well-being of a white woman. …

if a white woman has to suffer some so that she, a black woman, can survive, so be it. After all, white women have been surviving on our suffering for hundreds of years.” –Black Girl Dangerous (Her bold, not mine.)

Feminists declaring themselves “allies” with people who beat, rape, and murder women is, of course, as much a betrayal of feminism’s goals as Anarchist communities getting taken over by Marxists.

 

4. Rushton’s Race, Evolution and Behavior: A Life History Perspective (second abridged edition.)

Rushton lays out an impressive array of data in support of his theory that different branches of the human family tree (whites, blacks, and Asians,) mature at different rates (eg, different gestation lengths) and have different r/k reproduction strategies.

On a similar note, “Multiplication is for White People”: Raising Expectations for Other People’s Children is actually an anti-racist book. I only read the first few pages before I had to leave the bookstore, but the author had some interesting, Rushton-supporting information about cross-cultural infant development rates, including early crawling in African infants.

 

5. Next, I am totally going to finish Moby Dick.

The Insidious Approach of Death

A friend recently attended their 20th highschool reunion, the sort of event that makes one feel very old. Worse, three of their classmates have already died.

I thought that sounded way statistically unlikely, especially given the group’s demographics, but I ran the numbers, and it turns out that it’s only a little unlikely. Given the small N, we’re probably talking about random chance making the class unlucky rather than a particular propensity for death, but it’s unfortunate either way.

Highschool reunions are also a great (by which I mean depressing) opportunity to see who has aged the most. Some classmates look hardly older than the last time you saw them, while others look like they got hit by a semi full of old. Hopefully not you, of course.

In “Quantification of biological aging in young adults,” Belsky et al confirm what I’ve long suspected: that different people age at radically different rates, not just emotionally/mentally, but also biologically.

From the abstract: “We studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. We developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. Our longitudinal measure allows quantification of the pace of coordinated physiological deterioration across multiple organ systems (e.g., pulmonary, periodontal, cardiovascular, renal, hepatic, and immune function). We applied these methods to assess biological aging in young humans who had not yet developed age-related diseases. Young individuals of the same chronological age varied in their “biological aging” (declining integrity of multiple organ systems). Already, before midlife, individuals who were aging more rapidly were less physically able, showed cognitive decline and brain aging, self-reported worse health, and looked older.” (bold mine.)

” We scaled the Pace of Aging so that the central tendency in the cohort indicates 1 y of physiological change for every one chronological year. On this scale, cohort members ranged in their Pace of Aging from near 0 y of physiological change per chronological year to nearly 3 y of physiological change per chronological year.”

“Study members with advanced Biological Age performed less well on objective tests of
physical functioning at age 38 than biologically younger peers (Fig. 5). They had more difficulty with balance and motor tests (for unipedal stance test of balance, r = −0.22, P < 0.001; for grooved pegboard test of fine motor coordination, r = −0.13, P < 0.001), and they were not as strong (grip strength test, r = −0.19, P < 0.001).”

“Study members with older Biological Ages had poorer cognitive functioning at midlife (r = −0.17, P < 0.001). Moreover, this difference in cognitive functioning reflected actual cognitive decline over the
years. When we compared age-38 IQ test scores to baseline test scores from childhood, study members with older Biological Age showed a decline in cognitive performance net of their baseline
level (r = −0.09, P = 0.010).”

“Neurologists have also begun to use high-resolution 2D photographs of the retina to evaluate age-related loss of integrity of blood vessels within the brain. Retinal and cerebral small vessels
share embryological origin and physiological features, making retinal vasculature a noninvasive indicator of the state of the brain’s microvasculature (32). Retinal microvascular abnormalities are associated with age-related brain pathology, including stroke and dementia (33–35) … study members with advanced Biological Age had older retinal vessels (narrower arterioles, r = −0.20, P < 0.001; wider venules, r = 0.17, P < 0.001).”

“… these biologically older study members were perceived to be older by independent observers.”

“Based on Pace of Aging analysis, we estimate that roughly 1/2 of the difference in Biological Age
observed at chronological age 38 had accumulated over the past 12 y.”

“… our analysis was limited to a single cohort, and one that lacked ethnic minority populations. Replication in other cohorts is needed, in particular in samples including sufficient numbers of ethnic minority individuals to test the “weathering hypothesis” that the stresses of ethnic minority status accelerate aging.”

“Three Dunedin Study members had Pace of Aging less than zero, appearing to grow physiologically younger during their thirties.”

While I suspect measurement error is at play, I’d still like to know what those guys did.
