Life Expectancy

Life expectancy is a funny thing. It's NOT the age when you will probably die, it's the time when you have a 50/50 chance of dying. Life expectancy is not fixed, it extends as you get older, since each year you age eliminates more chances that you will die young. This is important because planning to have enough money to last just until the age of your life expectancy means there's a very good chance you'll outlive your assets.
