We are what we practice. Neuroscience has shown that our brains are plastic, constantly seeking new challenges and new stimuli. Our daily choices can drive this plasticity in either a positive or a negative direction, making our later years rich and enjoyable or predictable and limited. Keeping ourselves sharp, engaged and on the ball is critical to our emotional and physical well-being. In Brain Fitness Peak Performance, host Peter Coyote leads a journey to explore the extraordinary levels of skill and ability involved in music, sports and language and how we can apply the lessons of experts in these fields to out own lives. Bonus material features extended interviews with the neuroscientists featured in the program, focusing on the scientific background behind the expertise exhibited by the simultaneous interpreter, baseball players and musicians that were profiled.
