If you knew you were dying, what would you do with the time you had left?

For Debbie Whitmore, a young mother diagnosed with stage four colon cancer, the answer was simple: spend quality time, including a trip to Disney World, with her husband and four children.

Debbie and her family share their story in A Last Wish, an original FRONTLINE documentary short:

If you were in Debbie’s shoes and you knew your time was short, what would matter most to you?

It’s a question Dr. Atul Gawande, a surgeon and author of the best-selling book Being Mortal, encourages all of us to think about in his book and in tonight’s FRONTLINE film.
