Weakness feeds weakness


A collaborative Princeton research team of psychologists and neuroscientists have shown that physical exercise increases, so to speak, a brain’s resilience to anxiety. The team have shone light on the underlying substrates which, with the endorsement of further confirmatory research, naturally pave the way for the concept’s incorporation into the rapidly widening landscape of mental health treatments – widening in terms of pending possibility, even if still restrained by fledgling capability. Aside from those that have survived by chance, or arrived by mutation, all an organism’s traits must have endowed it with an advantage at some time in its history. As such, the study discusses the concept in evolutionary terms. Both ‘fight’ or ‘flight’ rely on physical proficiency. Physical proficiency, further still, is always relative to that reliably bigger fish. It follows, then, that less physically fit individuals would benefit, in survival terms, from an innate inclination to avoid having to impart either response.


“How could a thinking man have any self-respect whatsoever?” – Fyodor Dostoyevsky

A less filtered mind?

“The distance between insanity and genius is measured only by success” – Bruce Feirstein

These two articles look at the neural correlates of creativity and mental illness; unsurprisingly there is much to digest.



Smoother than ice

The combined ensemble of the articular surfaces covering the ends of the associated bones; the synovial capsule; and the contained synovial fluid, of human synovial joints, has a lower coefficient of friction than ice on ice. Joints like your knee, comprised of the components above, return less resistance to movement than you would feel pushing one block of smooth ice over another.

Smile and frown

The mouth, and the areas around it, as well as the eyebrows, are the most important in the perception of the facial expressions of others. Those regions convey the most information to another as your feelings are drawn on your face.


25% of the body’s metabolism takes place in the brain, in humans. That means 25% of the energy we use is used by our brains. Primates follow as the next closest using around 10% of their energy in their brains.
