We all know people whose lifestyle and health are such that they were not expected to live very long, yet some of them continue to live on well past life expectancy.
A more prudent approach is to prepare for maximum probable lifespan (i.e. the age where there is a one in 10 chance that you exceed), not merely prepare for your life expectancy. An even safer approach is to ensure you have enough money saved to fund your maximum possible lifespan, because otherwise, you’re still taking a gamble.
Addressing the uncertainty of our lifetimes is the most important challenge of retirement planning. If you use the standard population mortality tables to estimate life expectancy, you will have underestimated your lifetime, on average, about half of the time.
That’s because roughly half of all people die before reaching life expectancy, and half live beyond it, often far beyond it. To base a retirement plan on average life expectancy would be foolhardy because everyone is an individual, not a population. It would be sort of like playing Russian roulette with a two-shooter. Not too many people play that game. Unlike an insurer, individuals don’t have the luxury of ’diversifying’ the timing of their death across a large number of people of similar age and of relying on the Law of Large Numbers to reduce the variation around their own timing.
Speaking of insurance, when one purchases life insurance to provide an inheritance in case they die prematurely, through pooling large numbers of people, an insurer can offer a policy that costs much, much less than if you were trying to accumulate such a financial legacy without insurance, especially during the years prior to reaching life expectancy. That’s because through risk pooling, an insurer can price policies based on averages. For example, a 25-year-old has about a 1 in 1000 chance of dying during the year. By pooling numerous 25-year-olds, an insurer can charge them, for example $100 each plus administrative expenses and margins, for $100,000 of coverage. It would require much more saving to amass such a legacy without insurance.

 Attempting to project one’s own lifespan, if you correctly evaluate enough factors, may reduce the odds to those of a three-shooter, or perhaps even a four-shooter, but basing a retirement plan on that is still unwise.
