Modern advancements in network neuroscience, flow science, and embodied cognition have completely changed how we think about peak performance ageing. According to theory, these discoveries should enable elder athletes to advance in pursuits like park skiing that were once thought to be "impossible" (think: jumps and tricks.) Kotler tried to teach an old dog some new tricks in order to test his own ass-on-the-line experiment in applied neuroscience and later-in-life skill acquisition. The best athletes in the world are competing much past what was formerly thought of as their prime. Kelly Slater, the greatest surfer of all time, is winning tournaments in his fifties, and Tom Brady can outperform opponents half his age. What about the rest of us, though? Steven Kotler has spent thirty years researching how people perform, and taught hundreds of thousands of people at all skill levels, age groups, and walks of life, how to achieve peak performance. Could his own advice work for him?
