Is soy good or bad for me? |
The estimated per capita consumption of soybean oil increased >1000-fold from 1909 to 1999. (increase started during 60s)

Clinical studies show no effects of soy protein or isoflavones on reproductive hormones in men: results of a meta-analysis:
No significant effects of soy protein or isoflavone intake on T, SHBG, free T, or FAI were detected regardless of statistical model.

Discovering Limits to Growth | Do the Math
One may of course be skeptical that this general trend will also apply to the growth of our technology and economy at large, as innovation seems to continually postpone our clash with the ceiling, yet it seems inescapable that it must. For in light of what we know about physics, we can conclude that exponential growth of the kinds we see today, in technology in particular and in our economy more generally, must come to an end, and do so relatively soon.

PTSD: The War Disorder That Goes Far Beyond the Battlefield | Vanity Fair
This is an old problem, and today’s vets are not the first Americans to balk at coming home. A source of continual embarrassment along the American frontier—from the late 1600s until the end of the Indian Wars, in the 1890s—was a phenomenon known as “the White Indians.” The term referred to white settlers who were kidnapped by Indians—or simply ran off to them—and became so enamored of that life that they refused to leave. According to many writers of the time, including Benjamin Franklin, the reverse never happened: Indians never ran off to join white society. And if a peace treaty required that a tribe give up their adopted members, these members would often have to be put under guard and returned home by force. Inevitably, many would escape to rejoin their Indian families. “Thousands of Europeans are Indians, and we have no examples of even one of those aborigines having from choice become European,” wrote a French-born writer in America named Michel-Guillaume-Saint-Jean de Crèvecoeur in an essay published in 1782.

One could say that combat vets are the White Indians of today, and that they miss the war because it was, finally, an experience of human closeness that they can’t easily find back home. Not the closeness of family, which is rare enough, but the closeness of community and tribe. The kind of closeness that gets endlessly venerated in Hollywood movies but only actually shows up in contemporary society when something goes wrong—when tornados obliterate towns or planes are flown into skyscrapers. Those events briefly give us a reason to act communally, and most of us do. “There is something to be said for using risk to forge social bonds,” Abramowitz pointed out. “Having something to fight for, and fight through, is a good and important thing.”

Exposure to exogenous estrogen through intake of commercial milk produced from pregnant cows - Maruyama - 2009 - Pediatrics International - Wiley Online Library
7 men, 6 children, 5 women
After the intake of cow milk, serum estrone (E1) and progesterone concentrations significantly increased, and serum luteinizing hormone, follicle-stimulating hormone and testosterone significantly decreased in men. Urine concentrations of E1, estradiol, estriol and pregnanediol significantly increased in all adults and children. In four out of five women, ovulation occurred during the milk intake, and the timing of ovulation was similar among the three menstrual cycles.
