OneRepublic have released the music video for 'I Lived,' the sixth single off their 2013 'Native' album. The video is dedicated to a 15-year-old teen named Bryan Warnecke who lives with Cystic Fibrosis.

"Cystic Fibrosis is a disease that attacks the digestive system and slowly shuts down the lungs," Warnecke explains off-screen as the video begins. "I've been doing my treatments everyday of my life, so to me, it's just one of those things that's normal."

We then see footage of Warnecke biking up a mountain spliced with home videos of him growing up. Warnecke goes on to reveal that he is only expected to live until he's 36 years old.

"It's just one of those things that really makes you appreciate life. It makes me appreciate where you are, as a person," he says. "I want to make the most out of my life and have as much fun as I possibly can and my biggest fear is not being able to do that."
