When doctors discovered Kristin Johnson St. Goddard's breast cancer had spread to her lungs, they told her she had 18 months to two years left to live.

She and her doctors have no idea why she's still alive. The cancer has never been in remission, and has been classified as "stage four" the whole time.

Kristin says nothing is as important as simply appreciating life.

And, humor is important too. Whenever she leaves a phone message for anyone who hasn't called her back she readily reminds them, "I'm Stage Four, remember." And she's been kidding about it for years.
