The Scientific Method Produces General Principles by Whic...

Just as the first means by which science reduces the danger of error is the continual comparison of ideas and concepts, the second is the formulation of general principles by means of which we can understand cause-and-effect or sequential relationships among events. The function of a general principle or scientific law is twofold; to organize discrete objects and events in systematic order so that we can deal with them more effectively and exercise greater control over them; and to provide a ...

 Observation Provides Data on Problems, but Cannot Solve Them

A good illustration of the scientific method, in which observations are made for the purpose of identifying difficulties and analyzing situations, is the procedure followed by a physician when he makes a diagnosis. A doctor does not write a prescription solely on the basis of what his patient tells him; he uses instruments to take the patient’s temperature to examine his feces, and to analyze his urine. It is only after he has made these examinations that he writes his prescription; without...

 What Can You Do to Keep Your Metabolism High?

Although metabolism does tend to shift with age, decades of research demonstrate that such changes are not set in stone. By regularly checking the key biomarkers that reveal your muscle mass, mitochondrial health, thyroid function, inflammatory status, and glucose regulation, you can detect subtle signs of slowdown and respond with precisely targeted interventions. Below are several evidence-based approaches that, when integrated thoughtfully, can preserve—and even enhance—your metabolic ...

 A Brief Primer on TEE, BMR, RMR, and the Thermic Effect o...

When discussing human metabolism, four concepts often arise: total daily energy expenditure (TEE), basal metabolic rate (BMR), resting metabolic rate (RMR), and the thermic effect of food (TEF). Energy expenditure science can feel alphabet-soup–heavy, so let’s clarify these key terms in more depth: Total Daily Energy Expenditure (TEE): TEE is the total energy (calories) you burn in 24 hours. It encompasses every energy-demanding process in your body—from keeping your heart pumping to...

 Exercise Prevents Spending Calories on Fat Storage and Ot...

The reason for that is because exercise causes stress and that stress turns on a whole raft of beneficial effects. And there are really two kinds of this stress. Now, the first kind is energetic stress. Like I went for a run this morning, I spent probably about 500 calories running and I can only do so many things with the calories my body has. And if I spend 500 extra calories exercising, that means I'm not gonna spend 500 calories on other activities that my bother body might engage in. An...

 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) ...

 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...
