That year, I happened to become roommates with my childhood friend. He was in the ROTC, and one morning at PT he screwed up his knee during a drill. I remember him coming back on crutches, unable to walk on his own but still saying "Well, I'm still in ROTC so I have to go to the gym or do something. I just can't sit here and do nothing." Seeing that was what led me to stop lying around and make a change.
