What This is All About

    Predicting life expectancy is a very important tool to enhance life itself. It brings  greater accuracy and efficiency to calculations of insurance premiums, economic forecasts and societal developments. Above all, it allows us to optimally plan our life.

    Presently, life expectancy of an individual is calculated primarily on the basis of sex, race, nationality and age. Some life tables take smoking status into account as well. However, these few factors are far from being exhaustive. There are many others that contribute to our life expectancies. This project attempts to do just that- to include a host of other important variables to get a much more accurate estimate of an individual's life expectancy.

    Some of the many additional factors accounted for include height, weight, education, income, marital status, fitness, family health history, blood pressure, stress, driving, occupation, nutrition, depression, sexual practices, and sleep.

    An intra-year exponential distribution, with the parameters being modified by individual relative risks, was used. Details of the statistical procedure used can be found in  Demonstration of Procedures.
