 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...

 Today's Wants Become Tomorrow's Needs

I like going to coflfee shops occasionally, but now that Starbucks is here, I need my coffee, and that new need has spawned a whole new industry. I always wanted to be able...

 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...

 1.6 Grams of Protein a Day Per Kilogram of Weight

To answer the simplest question of whether taking in more protein during weight training led to larger increases in muscle size and strength, the researchers added all of the results together. [...] But those who did ramp up their protein gained an extra 10 percent or so in strength and about 25 percent in muscle mass compared to the control groups. The researchers also looked for the sweet spot for protein intake, which turned out to be about 1.6 grams of protein per kilogram of body weig...

 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...

The studies fail to take into account that many abstainers are former alcoholics who are biased toward ill health.

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...

 Cooperative Game of Competitive Questioning

Great Cooperative games make the play experience deliberately difficult; the game shouldn't be a cake walk. Mr. Glass's decision, therefore, is for him to assume the role of the game and present himself in opposition to his students—the players. He does this by instructing his students (working in groups designed to get everyone working together, especially those who have struggled in the past) to prepare 30 questions that, in their estimation, adequately assess or measure the topics with w...
