Can someone please give me a formula for calculating the chance of living N years, given your current age? I really want to know so I can calculate the probability of living to the age of 1000 years or maybe even 4198862272127 years (if the formula holds for that high a number). Also, I need a table to check against the formula.

 2012-09-02, 22:40 #4 jeebee   Sep 2011 2·3 Posts If you're asking for God's formula, I'm afraid we won't see it in this lifetime. Otherwise, actuarial science uses empirical evidence along with probability measures to compute these values. Since no one firm uses the same data, there is no consensus on these statistical measures. The day will come when data will be centralized but insurance is still a capitalist game and historical data is still considered a private asset. Furthermore, one can argue that historical data should be given less and less weight as the years go by. Think of the advancement of medical science but also environment contingencies which along with many other influences modify significantly the observed mortality. On topic, the usual notation is npx, which means the probability that a person of age x survive at least n years. It is computed precisely using a mortality table and will therefore match the 'expected' result...It should also be clear at this point what the probability of what you're asking is. You may want to search for public domain mortality tables to get some practice. Last fiddled with by jeebee on 2012-09-02 at 22:42

Depends upon how you define 'live'. If it is merely for existing and keeping your heart beating then IMO that is not living. Without Mini-me to complete me I would not be living regardless of whether my physical body is still in good working condition.
