I really enjoyed this New York Times article:
http://www.nytimes.com/2012/01/10/health/elderly-experts-share-life-advice-in-cornell-project.html?_r=2&smid=fb-nytimes

I loved this quote: “I chose to live each day as if it could be my last — but with a watchful eye on the future in case it wasn’t.”

Enjoy!
