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...

 Star Wars Nostalgia VS Star Trek Futurism

Also, Star Wars is set in a fantasy past that can look like anything, while Trek is supposed to be a projection of what we imagine our own future to look like. And Star Wars has always been an exercise in nostalgia from the start — nostalgia for ’30s movie serials and comic strips, for ’40s war movies, for ’50s hot rods and samurai movies, etc. It’s always, always been based on the past and set in the past. Star Trek looks to the future, and our idea of the future is always changing.

 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...

 Exercise Releases Brain-Healthy Proteins

We all know that exercise is important for a strong and healthy body. Less appreciated is that exercise seems also to be important for a strong and healthy mind, boosting memory and learning, while possibly delaying age-related cognitive decline [1]. How is this so? Researchers have assembled a growing body of evidence that suggests skeletal muscle cells secrete proteins and other factors into the blood during exercise that have a regenerative effect on the brain. Now, an NIH-supported study...

 Exercise "Sweet Spot" for Extending Lifespan

They found that, unsurprisingly, the people who did not exercise at all were at the highest risk of early death. But those who exercised a little, not meeting the recommendations but doing something, lowered their risk of premature death by 20 percent. Those who met the guidelines precisely, completing 150 minutes per week of moderate exercise, enjoyed greater longevity benefits and 31 percent less risk of dying during the 14-year period compared with those who never exercised. The sweet s...

 Ideal Amount of Exercise for Longevity

People who got some exercise, but not enough to meet the physical activity recommendations were still 20 percent less likely to die over a 14-year period than those who did not do any physical activity. (The recommendations say to do 150 minutes of moderate activity per week or 75 minutes of vigorous activity per week.) People who engaged in the recommended level of physical activity saw even more benefit: They were 31 percent less likely to die during the study period, compared with those w...

 People With High Cognition Want More

First, it seems to me (based on anecdotal evidence and personal observations) that people who are already endowed with above-average cognitive capacities are at least as eager, and, from what I can tell, actually more eager, to obtain further improvements in these capacities than are people who are less talented in these regards. For instance, someone who is musically gifted is likely to spend more time and effort trying to further develop her musical capacities than is somebody who lacks a m...

 RPG as Collaborative Creation

Playing D&D is an exercise in collaborative creation. You and your friends create epic stories filled with tension and memorable drama. You create silly in-jokes that make you laugh years later. The dice will be cruel to you, but you will soldier on. Your collective creativity will build stories that you will tell again and again, ranging from the utterly absurd to the stuff o f legend.

 Exercise of Directing a Child's Focus

OK, Nicole, while you’re lying still, move your eyes around the room. Even without moving your head, you can see the lamp over on the table. Now look over at your baby pictures. See them? Now look at the bookcase. Can you see the big Harry Potter book there? Now look back at the lamp. Do you see how you have the power to focus your attention all over this room? That’s what I want to teach you about, but we’re going to focus your attention on what’s going on inside your mind and body. ...

 The Bonds Revealed Through Taxonomy

From the most remote period in the history of the world organic beings have been found to resemble each other in descending degrees, so that they can be classed in groups under groups. This classification is not arbitrary like the grouping of the stars in constellations. The existence of groups would have been of simpler significance, if one group had been exclusively fitted to inhabit the land and another the water; one to feed on flesh, another on vegetable matter, and so on; but the case i...
