Working with Actuary Jeremy Clear, a mortality calculator was developed to determine individual life expectancy to the second. The peer-reviewed research is based upon mortality studies of relevant factors such as family history, lifestyle and health data. A Custom designed digital clock is programmed with the subject's date and time of birth and counts down to the estimated time of death in seconds. A GPS receiver regularly updates the current time via satellite to ensure the continuation of the countdown. Additional clocks are programmed with other individual's data.
