Though the brain makes up just 2 percent of the body’s weight, it consumes 20 percent of its energy. Normally about 50 percent of the brain’s energy consumption goes to managing balance. But when the brain senses imbalance–and particularly when it thinks you’re sinking–it goes into critical mode and nearly 100 percent of its energy is consumed with trying to fix that.
Until you fix ‘that sinking feeling,’ you have no chance of becoming comfortable or efficient. And with that amount of energy waste, it makes no sense at all to try to ‘tough it out.’ Before tackling even the most rudimentary skills, we need to send the brain unambiguous signals that we’ve got control of body position. That frees up the mental energy to focus on skills that require some degree of calm focus.
