Rio Olympics: Daniel Smith overcomes addiction to join swimming team

Smith was a talented junior swimmer and won a string of Australian Junior Championships, but in his late teens ice pushed his life off the rails and he was soon living on the street.

"It was difficult, but I guess the pain that I suffered, the pain that I dealt with has actually put me in a position now to give back to others," he said.

"That's what my life's all about now. I'm all about giving hope to the next generation and giving hope to other people who are addicted to drugs."
