James Hewitt is Head of Science & Innovation at Hintsa Performance. His work includes consulting with Formula 1 drivers and teams, work in elite sport and with global corporations, a wide-range of written articles, presentations, keynotes and workshops in Europe, the United States and Asia.

In this interview with Dr Tommy Wood, James discusses a polarised approach to cognitive performance, arguing that time spent in the middle gear is time wasted. James also explains why smartphones are so compelling yet interfering with our ability to concentrate.
