Living to 100, By Dr. Thomas Perls

Expanded from the ground-breaking book Living to 100.

Life Expectancy Calculator

The Living to 100 Life Expectancy Calculator uses the most current and carefully researched medical and scientific data in order to estimate how old you will live to be. Most people score in their late eighties... how about you?

The calculator asks you 40 quick questions related to your health and family history, and takes about 10 minutes to complete. At the end, you will be asked to create an account to store your answers.

Dr Tom Perls

In addition you will receive:

  • Personalized feedback for each of your answers
  • A Personalized "To-Do" list for you and your physician
  • A list of things you can do differently and how many years you will add if you do so
  • The option to sign up to take the calculator again so you can keep track of your answers and see if your calculated life expectancy gets better or worse. We will send you a yearly reminder to come visit us!

Thanks for providing this interesting site — it's good to know how one is getting on! I am going to suggest that my husband does the questionnaire — it might frighten him into giving smoking up, and my daughter might be encouraged to stop her bad eating habits!


Just this week, I'm announcing my retirement at work — effective in June — and it was terrific to have a cheery prognostication of nearly thirty years to enjoy it in! (And that's without looking up my blood pressure figures, which I'm always told are stellar!) Your "test" was easy and fun to take and encourages me to continue doing what I do well and to address those areas where I know I could improve. Now, if the results only came with a guarantee...


I found this very enlightening… and encouraging! As a school nurse, I will recommend it to our staff.
