In boxing you either die a hero or live long enough to become a cautionary tale, and seldom does a boxer get to choose his or her own ending. For some, death is a quite literal thing, which is what makes the idea of fighting, let alone fighting too long, a scary proposition to even consider. For others — that is, the majority — death is experienced only in the sense of one’s career; the identity, the purpose, the relevance. All this disappears, or dies, the moment fighters have both thrown and received their final punch, and the void created is often what causes the deferring of this death by way of either reinvention or denial.
