Yeah. I remember when I first began doing photofocus on books, I did it on other things. In P.E., I started doing it during games, and my visual reflexes are WAY better. It's crazy.
One day there was a basket ball kicked against the wall, and it came at my side traveleing at least 40-50mph off that friggin' wall. I just brought my fist up, and without even thinking about it - hit the ball away. I'm completely calm. I'm not afraid of anything flying at me anymore.
