“Memory can be dramatically disrupted if you force something that’s implicit into explicit channels. Here’s an example that will finally make reading this book worth your while—how to make neurobiology work to your competitive advantage at sports. You’re playing tennis against someone who is beating the pants off of you. Wait until your adversary has pulled off some amazing backhand, then offer a warm smile and say, “You are a fabulous tennis player. I mean it; you’re terrific. Look at that shot you just made. How did you do that? When you do a backhand like that, do you hold your thumb this way or that, and what about your other fingers? And how about your butt, do you scrunch up the left side of it and put your weight on your right toes, or the other way around?” Do it right, and the next time that shot is called for, your opponent/victim will make the mistake of thinking about it explicitly, and the stroke won’t be anywhere near as effective. As Yogi Berra once said, “You can’t think and hit at the same time.”
