John Shoffner joins me to talk about how to maintain and even improve your driving performance as you get older. We talk about diet, supplements, mental training, fitness, and the basic differences between young and older drivers.

John started racing at the age of 58, and within a year was racing in the VLN series at the Nurburgring. With a steep learning curve like that, he’s done everything he can to minimize the effects of aging, and now feels he’s fitter – physically and mentally – than he was decades ago.

John’s Speed Secret: Always be at the limit.
