"Never Give Up."

This is Diana Nyad.

Have you heard her story?

She swam for 52 hours+ for 111 miles,

from Cuba to Key West, FL.

She is 64.

She is the first swimmer to ever accomplish this.

She tried to do this 4X's before.

The first time in 1978, decades ago.

She even gave up swimming for years.

She didn't use a shark cage, wet suit, or flippers.

When she came ashore on Monday,

after accomplishing her goal,

she said,

"Never give up. . .

You are never too old to chase your dreams."
