Descartes was right . The mind and body work together. The better they get along, that is, a well cared for body can better support a strong, lean thinking machine. Snakes do it the same way every day . Rituals, automatic ways to deal with common experiences, give way to productive expression.
Productive rituals reduce stress, thus increasing creative ways of thinking.
Brains thrive to survive . Brains are designed to learn, not teach. They drain when all of the attention is on teaching and learning lacks choices. Peaks and troughs make a brain flow . Evaluation is more critical to the brain than assessment .
