About the Calculator
This Calculator is based on a quiz Harvard Medical School researchers Thomas Perl, M.D. and Margery Hutter Silver, Ed.D. developed to help you calculate your life expectancy. The quiz was developed after a rigorous study of 150 centenarians.
To compute your life expectancy, the calculator sums all of the individual score points together. The result may be negative, zero, or a positive number. The calculator program then divides the result by 5. The result of this division is then added to 84 if male or 88 if female, producing life expectancy in years.
