 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...

 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...

 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...

 Lower Mortality in Moderate Drinkers VS Abstainers Result...

RESULTS: Without adjustment, meta-analysis of all 87 included studies replicated the classic J-shaped curve, with low-volume drinkers (1.3-24.9 g ethanol per day) having reduced mortality risk (RR = 0.86, 95% CI [0.83, 0.90]). Occasional drinkers (<1.3 g per day) had similar mortality risk (RR = 0.84, 95% CI [0.79, 0.89]), and former drinkers had elevated risk (RR = 1.22, 95% CI [1.14, 1.31]). After adjustment for abstainer biases and quality-related study characteristics, no significant r...

 Health Concerns Spark Adult Interest in Science

Beginning in middle age and continuing through later adulthood, individuals are often motivated by events in their own lives or the lives of significant others to obtain health-related information.^^ Health-related concerns draw many adults into a new domain of science learning. At the same time, with retirement, older adults have more time to devote to personal interests. Their science learnmg addresses long-standing scientific interests as well as new areas of interest.^^ Adults differ fr...

 Evolutionary History Through Macro and Micro Observations

Everything in the cosmos has a history. The old dichotomy between the "historical" sciences (like geology, paleontology and evolutionary biology) and the (for want of a better term) "functional" sciences (like physics and chemistry—some would call them the "real sciences") was always supposed to be that fields like physics study dynamic processes and discover immutable laws of interaction among particles composing the cosmos—while the historical sciences study, well, history—the suppose...

 Longest Ever Personality Study Finds No Correlation Betwe...

There is evidence for differential stability in personality trait differences, even over decades. The authors used data from a sample of the Scottish Mental Survey, 1947 to study personality stability from childhood to older age. The 6-Day Sample (N = 1,208) were rated on six personality characteristics by their teachers at around age 14. In 2012, the authors traced as many of these participants as possible and invited them to take part in a follow-up study. Those who agreed (N = 174) complet...

 The Machine Euthanizes the Atheletic

"Well, the Book"s wrong, for I have been out on my feet." For Kuno was possessed of a certain physical strength. By these days it was a demerit to be muscular. Each infant was examined at birth, and all who promised undue strength were destroyed. Humanitarians may protest, but it would have been no true kindness to let an athlete live; he would never have been happy in that state of life to which the Machine had called him; he would have yearned for trees to climb, rivers to bathe in, meado...
