WILL I LIVE TO BE 100?

For an estimate of how long you will live, you can take a free 10-minute online quiz, answering 40 questions about your health, habits and family, including: Do you take an iron or calcium supplement? Floss? Sleep fairly well? How many new friendships have you developed in the past year?

The Living to 100 Life Expectancy Calculator is based on longevity research conducted by the New England Centenarian Study at Boston University.

In addition to an estimated life expectancy, the program suggests ways you can extend your life.
