This Device Helps Paralyzed People Breathe--and Sing

In his early twenties, Lee Nam-hyun was an avid swimmer. But in 2004 he broke his neck in a pool, which left him paralyzed from the shoulders down. Recovery from his injuries required years of rehabilitation. The accident also temporarily halted his lifelong passion for singing. Opera and K-pop songs are his favorites, and being able to sing again became one of his top goals in recovery.
