PLAYA VISTA (CBS) — A Playa Vista non-profit is trying to determine the secrets of a long life.

If you’re a centenarian, or know one, they want to hear from you.

The X Prize Foundation says their mission is simple — benefit humanity.

Philanthropists and companies donate funds. The foundation puts on competitions with cash incentives.

Five companies from around the world will study the DNA make-up of 100 centenarians.

There are an estimated 53,000 living centenarians in the United States.

The search for centenarians ends May 31.
