NBA Hall of Famer Magic Johnson is featured in a new Web video from the White House promoting the Affordable Care Act.

In the video, Johnson, who was diagnosed with HIV in the early 1990s, says he likely would be dead right now if he didn't have quality health insurance. He also urges young people, who haven't been signing up for Obamacare in as high a numbers as the law needs, to do so.

"Young people, they think they're Superman, like nothing's ever going to happen to them," Johnson says. "But trust me: One day, something's going to happen."

Johnson also wrote a blog post for the WhiteHouse.gov Web site.
