Yes. I played sports. I compare your comment with a Tennis study done analyzing top players and how they act between points.

The players who rested their brains and regained focus were more successful. The players who stayed amped were less successful.

And I know, you can't compare Tennis and Football. So dumb, right?. But they are similar in that they are sports where you have short periods of maximum effort followed by stoppages of play.

Anyway, interesting thoughts.
