Thai prisoner Changsuk P.U Suphap is massaged by his trainer before his match in "Fighting Backwall" at Klong Prem Central Prison in Bangkok June 26, 2014. Bangkok's Klong Prem prison organized the "Fighting Backwall" contest to "return good people to society" and fight drug abuse by training inmates in Muay Thai or Thai boxing and getting them to compete with professional boxers from outside. Muay Thai is Thailand's national sport and is said to be 2,000 years old. REUTERS/Athit Perawongmetha (THAILAND - Tags: CRIME LAW SOCIETY SPORT BOXING) less
