Phelps puts his mind to helping others

SYDNEY, Australia - Michael Phelps, the most decorated Olympian of all time, on Monday joined the board of an Australian mental health company, a subject close to his heart after his struggles with depression and substance abuse.

The American, who won 28 Olympic medals and quit swimming last year, said joining Medibio met his aim to raise awareness of mental health problems.

"I personally suffered from mental health challenges from my teenage years on, and only fairly recently - after reaching a point of desperation - did I acquire the understanding, treatment, and support I needed, which has truly changed my life," he said.
