I did not enjoy the violence of boxing so much as the science of it. I was intrigued by how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat, how one paced oneself over a match.

Boxing is egalitarian. In the ring, rank, age, color, and wealth are irrelevant . . . I never did any real fighting after I entered politics. My main interest was in training; I found the rigorous exercise to be an excellent outlet for tension and stress. After a strenuous workout, I felt both mentally and physically lighter. It was a way of losing myself in something that was not the struggle. After an evening’s workout I would wake up the next morning feeling strong and refreshed, ready to take up the fight again.
