Life-Expectancy Calculator

The Martha Stewart Show, October 2007

The Living to 100 Life-Expectancy Calculator was developed by Dr. Thomas Perls, founder of the New England Centenarian Study, the largest study of centenarians and their families in the world. The people working on the study are vigorously looking for the genetic key to longevity

The calculator asks you 40 quick questions related to your health and family history, and takes about 10 minutes to complete. (It takes longer if you lie or cheat, so be honest!)

It calculates how many years you are likely to live based on your lifestyle, by incorporating numerous observational studies and actuarial science, a method using statistical and mathematical research (this is used by insurance companies to determine how healthy you are compared to others in your age group.) The average life expectancy in the United States is about 75 years old; most of the people taking the test fall near there.

    The link worked for me, and I think it was very accurate. My great-grandparents lived to about 92, and it said I would probably live to around 91. Based on my lifestyle, I agree. This was a neat calculation.

    It wouldn't let me get past page 1

  • Marybel57 23 Mar, 2008

    I wasn't very comfortable with giving my personal info either,so I deactivated
    my account. I thought that seeing how long that I would have to live was neat ...But only our Lord know when our number is up.

  • merrysage 26 Feb, 2008 is a dead link.

  • ringlet1 13 Feb, 2008

    I liked it. I didn't think that the questions were too personal. I did get sent back on one page. Sometimes the page problems may be with your server, instead of with the web site you're viewing.

  • akeehner 8 Feb, 2008

    I took the test until I was asked to register and then I cancelled out. If I had known that this required registration I would not have even bothered. My personal information is just that - personal. Very disappointing

  • AuntBoo 2 Feb, 2008

    Either I did this test before or they're having server problems from all the Martha readers clicking over to take the test, 'cause I couldn't get past the registration page and there was no link to recover a lost password. BTW, there ought to be a "not so good" category for article ratings.

  • Levis-Mum 31 Jan, 2008

    easy to do

  • Rosalia 22 Jan, 2008

    I didn' have a problem, no personal information was requested of me. My results were great!

  • NataliePoppet 20 Jan, 2008

    I just did the test and i didnt have to register? I just clicked on the link :)

  • dotsonjudy 18 Jan, 2008

    I got stopped after the registration process which I really didn't want to do and never got my score. What a waste of my time!!!!!!!!!!!!!!!!!!

  • alecsj 16 Jan, 2008

    The personla questions are not too personal like your social security #. It's for example what is your cholesterol level...or did your grand parents live past 98...and so on. Nothing you put there will identify you. Pretty safe to do.

  • hokie01 31 Dec, 2007

    I just stumbled across the difference. When I used the calculator for myself I didn't have to register or have any problems. When I asked my mom to take it and read her the questions over the phone that was when I had to register. I believe the different comments are coming from the two different age groups. Your age determines which calculator you need to use and the calculator for the 49 and up group is the one that you have to register with an email address and screen name.

    This is such a great educator to help yourself! Thanks Martha for helping us to help ourselves. It's very personal and gets right to the point. Love it! So far, it looks like I may be around till 86 before any lifestyle changes---woo hoo! Yeah me! Hopefully, Social Security will still be in place then. Oh well, no point in worrying now about it. Cheers and Happy New Year everyone!

  • Belmont 29 Dec, 2007

    Something is wrong with the system-can't get past #1. Very disconcerting to read the comments aout giving out personal info. This is not Martha's usual high quality product.


  • jasper_10981273_963 29 Dec, 2007

    I guess I was one of the lucky ones that didn't have any problems with the questionaire. It only took about 15 minutes, and I printed out a copy of the results. My life expectancy is only 62, so I will be making some lifestyle changes. Thanks Martha, you did some real good here.

  • elsie6 29 Dec, 2007

    i took the test 4 times and there was all ways something i had to answer the questions several time and got error on my emailaddress was wrong i thank four times was one time to many

  • gsdlady 29 Dec, 2007

    I had no trouble with the test. I was sent back a couple of times, but it worked out ok. I jope I will take advantage of the material feedback.

  • psickles 29 Dec, 2007

    I am so disappointed that I was not able to get the results. After completing the survey, I got error messages saying that there was a problem either with my e-mail or username. Nothing worked that I tried.

  • scottdennis 29 Dec, 2007

    The quiz worked fine for me. Lots of interesting points raised and worth completing

  • Lorraine1 29 Dec, 2007

    This was a waste of time as far as I am concerned. After taking the survey I just kept getting the error that my e-mail address was wrong. There seem to be many negative comments about this. Is it going to be fixed?

  • twinkle 28 Dec, 2007

    I answered page 1, then page 2, then was sent back to page1, answered again, sent back to beginning, filled in same answers, was sent back to beginning....SO, I am finished. Too bad to waste so many peoople's time.

  • hokie01 28 Dec, 2007

    I just used the calculator and I didn't have any problems nor did I have to enter any personal information to get the score. It was at the top of the next page after you submit your quiz. You can enter your email at the end to email the results to yourself but you can also just print them out without entering the email. Contained lots of good info and the results were as promised on the show.

  • Minnie_Mouse 28 Dec, 2007

    Unfortunately this Life-Expectancy Calculator Quiz turned out to be just a way to get personal information to share with advertisers and other third party web sites. After taking the quiz you are not allowed to find out your results unless you register with a web site that will share your information. Please read their "privacy policy." "What a Scam." I'm disappointed that the Martha Stewart Company did not check further into this company before offering this so called free quiz to it's viewers.

  • goofydog 28 Dec, 2007

    I do not see where the test is being offered. So cannot even take the Life-Expectancy Calculator. Poor site? Too many people taking the test? I'm just simply too dumb? Perhaps all of the above?...

  • MaryAnn1 28 Dec, 2007

    Could not get passed the registration process. I tried 4 times. Said that my email or username already exists. Used the same email and user name for the registration on I gave up.

  • tinabear 28 Dec, 2007

    Wow! I wanted to take the " calculate your life test", but I couldn't get past the section 3; or into the nuitrition section. I tried several times, but it kept throwing me bact to section 2. 'thanks for the chance to try. "tina"

  • redseamom 27 Dec, 2007

    I did not need to register. My life expectancy is 95 -- so I am not too motivated to make major changes to add an extra year or two!

  • kathrynharrison 27 Dec, 2007

    I did this without registering and it was not a problem. I am also going to live to 100 so that is nice!! Unfortunately my husband is only going to make it to 82!

  • Paula2 27 Dec, 2007

    I could not get pass the registration as well. Whats the problem. Seems like alot of people had the same problem. This took time and then no results. Not good.
    I appreciate an apology for my taking my time.Paula

  • joniken 27 Dec, 2007

    After taking a long amount of time I could not register. This is really a mess. I am a professional and know my way around computers and programs. This one needs revamping and fast. All your contributor's Martha are taking time to do this with no results. What a waste of my precious time. jonicour

  • redwine48 27 Dec, 2007

    I couldn't get past registration either. kept saying I all ready existed in their computer.
    But that's impossible. Oh well, I'll just do things the old fashion way and wait it out.

  • leechambers 27 Dec, 2007

    I answered the questions but could not get past the registration.

  • leechambers 27 Dec, 2007

    I answered the questions but could not get past the registration.

  • diannebaxter 27 Dec, 2007

    I didn't get my score either.

  • myshatto 27 Dec, 2007

    I signed in as a member and the calculator did not show up. When I tried it the first time it said I was already registered but did not give me my score. can someone send it to me? My lifestyle and blood pressure numbers have changed

  • pattyjam 27 Dec, 2007

    I was able to do the first page, when I was changing to Step 2 it cycled back to the first page of questions again.

  • annmariegamm 27 Dec, 2007

    I can not sign on the questionaire. It keeps refering me back to the start.
