Peer 1 client Robert A. plays hopscotch with his 5-year-old daughter Isabella during Kid's Day at Peer 1 in Denver November 7, 2015. Peer 1 is a drug and alcohol rehabilitation programme for men, many having spent years in and out of prison, in Denver, Colorado. The men have often tried and failed over and over to turn their life around. With histories of abuse as children and living on the streets, they come to Peer 1 hoping to turn away from addiction and crime, to rebuild their lives and learn how to integrate into society. Treatment includes family group therapy, meditation and trust-building exercises. REUTERS/Rick WilkingPICTURE 25 OF 26 FOR WIDER IMAGE STORY "PEER 1: PRISON, DEATH OR RECOVERY".
