 We're joined this morning by Dr. Steven Sidorov, a PhD, a psychologist, and internationally recognized expert in resilience and optimal performance. He's also the author of his latest book, The Nine Pillars of Resilience, The Proven Path to Master Stress, Slow Aging, and Increased Vitality. Professor, can you talk about some specific lifestyle factors such as diet, exercise, and especially sleep that can really be important today?
