Check out this fascinating site where you input personal data to answer 40 questions about your lifestyle and family and in return receive a prediction of your life expectancy and some suggestions as to how you can improve it based on your input. The questionnaire takes about 10 minutes to complete.

The index was devised by Thomas Perls MD, MPH, who is the founder and director of the New England Centenarian Study, the largest study of centenarians and their families in the world.

The index is an extension of a book that Dr. Perls wrote entitled 'Living to 100: Lessons in Living to Your Maximum Potential at Any Age.'
