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 level...31 OCT 2018 by ideonexus
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 supporter wheth...27 JUL 2018 by ideonexus
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. It is a fa...27 JUL 2018 by ideonexus
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. Fighting of...20 MAR 2018 by ideonexus
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...Folksonomies: longevity alcohol consumption
Folksonomies: longevity alcohol consumption
The studies fail to take into account that many abstainers are former alcoholics who are biased toward ill health.

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...As do novelty, wonder, self interest, and relevance to personal.

The Fraud of Agriculture
Scholars once proclaimed that the agricultural revolution was a great leap forward for humanity. They told a tale of progress fuelled by human brain power.Evolution gradually produced ever more intelligent people. Eventually, people were so smart that they were able to decipher nature’s secrets, enabling them to tame sheep and cultivate wheat. As soon as this happened, they cheerfully abandoned the gruelling, dangerous, and often spartan life of hunter-gatherers, settling down to enjoy the pl...21 NOV 2017 by ideonexus
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 supposed outc...20 JUN 2017 by ideonexus
