NAKHON RACHASIMA, THAILAND - 2014/02/13: Zac, a foreign challenger from Canada, is encouraged by his coach to fight in the third round against one of the prisoners during a boxing match; convicts from some Thai prisons are allowed to train for boxing matches in which they can reduce their sentences after winning fights. Thai prisoners, many of them hardened by years of incarceration, were pitted against free foreign fighters in both Muay Thai and traditional boxing bouts. Both sides were competing for a little cash, but the Thai prisoners were also fighting for their lives, literally. Prisoners who win a championship and thereby bring glory to the prison have a realistic shot at having their sentences commuted. The organizer said this goes for any prisoner regardless of the magnitude of their crime, but he was also quick to point out that prisoners are judged from a holistic perspective that incorporates their behavior outside of the ring. That said, it doesnt diminish the gravity of whats at stake. - Coconuts Bangkok. (Photo by Jonas Gratzer/LightRocket via Getty Images)
