The WSJ for this weekend has a worthwhile article (behind a pay wall) entitled, "The 15 Numbers Every Investor Should Know." Among those numbers is one's life expectancy, that is, the age to which the subject should assume he or she will live. (Obviously, savers and investors should be interested in this number.) The article links to a website called "Living to 100," which includes a "Living to 100 Life Expectancy Calculator." By answering a few multiple choice questions, the calculator will give you the last anniversary of your birthday. Mine is 96.
The site will give you not only the age to which you can expect to live, but also a set of comments and suggestions in light of your answers to the multiple choice questions. Most of the comments and suggestions make sense, but there is one that is troubling. Because I answered that I consume very few dairy products per week, there is a recommendation that I consume more to avoid osteoporosis. Apparently, the author of the calculator, Thomas Perls MD, MPH, FACP, did not get Dr. McDougall's memo. A diet full of vegetables and a life with periodic exercise should result in enough calcium to keep one's bones strong.
