 Why Humans Evolved to be Active

Humans of all to be much more physically active than our ape ancestors. Typical chimpanzee walks maybe two to three kilometers a day, and they take maybe what, three, 4,000 steps a day. A typical hunter-gatherer takes about 15 to 20,000 steps a day. Per kilo hunter-gatherers spend about twice as much energy per kilo on being physically active per day than our ape cousins. And importantly, that physical activity occurs as we age, right? So Americans are pretty inactive, as we all know. A typ...

 Digestive Enzymes Leaking into the Body May Increase Aging

In young rats, the researchers found low levels of the protein-breaking enzyme trypsin, although the tiny folds (villi) of the small intestine and the lungs contained more of this molecule. However, trypsin levels were much higher in old animals. “High densities are on sections of the intestine, liver, and lung, organs that are in the pathway of digestive enzymes leaking from the small intestine,” the paper says. Elevated levels of other digestive enzymes (elastase, lipase, and amylase) ...

 The Chess Stress Response

Another aspect of chess as a sport is the intense psychological and physiological exertion involved in a competitive chess game, and the crisis after the game. What sports science calls the "stress response process" is at least as powerful in chess as it is in more physical sports. When I say exertion, I am not referring only to the mental gymnastics of moving the pieces in our minds, but also the huge nervous tension that fills you before and during the game, tension that rises and falls wit...

 Exercise Meaningful in Having Good Mental Health

In this cross-sectional study, we analysed data from 1 237 194 people aged 18 years or older in the USA from the 2011, 2013, and 2015 Centers for Disease Control and Prevention Behavioral Risk Factors Surveillance System survey. We compared the number of days of bad self-reported mental health between individuals who exercised and those who did not, using an exact non-parametric matching procedure to balance the two groups in terms of age, race, gender, marital status, income, education l...

 Kayfabe

Although the etymology of the word is a matter of debate, for at least 50 years “kayfabe” has referred to the unspoken contract between wrestlers and spectators: We’ll present you something clearly fake under the insistence that it’s real, and you will experience genuine emotion. Neither party acknowledges the bargain, or else the magic is ruined. [...] The aesthetic of World Wrestling Entertainment seems to be spreading from the ring to the world stage. Ask an average Trump support...

 Infective Hallucination in "Martian Chronicles"

The psychologist shut his eyes and scratched his nose. “This is the most incredible example of sensual hallucination and hypnotic suggestion I’ve ever encountered. I went through your «rocket,» as you call it.” He tapped the hull. “I hear it. Auditory fantasy.” He drew a breath. “I smell it. Olfactory hallucination, induced by sensual telepathy.” He kissed the ship. “I taste it. Labial fantasy!” He shook the captain’s hand. “May I congratulate you? You are a psychotic...

 Children are Smarter Than Adults

This precocity of childhood may be said to characterise all the known races of man, and to be even more marked the more primitive the race. On this point, ‘It is an interesting fact,’ says Havelock Ellis (183, p. 177), ‘and perhaps of some significance, that among primitive races in all parts of the world, the children, at an early age, are very precocious in intelligence.’ And again, ‘ It seems that, the lower the race, the more marked is this precocity, and its arrest at puberty. ...

 Heritable IQ is Boosted by Environment, Just Like Height

hough it’s not easy to pinpoint the causes of the rise in IQ scores, it’s no paradox that a heritable trait can be boosted by changes in the environment. That’s what happened with height, a trait that also is highly heritable and has increased over the decades, and for some of the same reasons: better nutrition and less disease. Brains are greedy organs, consuming about a fifth of the body’s energy, and they are made of fats and proteins that are demanding for the body to produce. Fig...
